Ukusilela kwebhetri yeLithium-ion kunye nokudumba

Amanani kaxakeka ayohluka ngokwamazwe. Eli phepha lisebenzisa u-911, inani laseMelika naseKhanada. Amanye amazwe amaninzi asebenzisa i-112, 999, okanye elinye inani. Fumana inombolo yelizwe lakho.

Rechargeable lithium-ion and lithium-polymer (LiPo) pouch and cylindrical batteries power almost every modern portable device: smartphones, laptops, tablets, USB power banks, vapes, cordless power tools, and electric bicycles or scooters. When these high-energy-density cells suffer physical impact, manufacturing defects, severe deep-discharge aging, or overcharging with uncertified bricks, their internal electrolytes break down. This degradation causes the battery pouch to swell like a tight balloon ("spicy pillow") and can escalate into an uncontrollable, self-oxidizing 1,000-degree-Celsius (1,832-degree-Fahrenheit) chemical blowtorch fire known as thermal runaway.

Because a lithium-ion cell generates its own internal oxygen as its metal-oxide cathode breaks down, a burning battery cannot be smothered by cutting off air, it can burn even underwater or inside a closed pot, while venting clouds of toxic, flammable hydrogen fluoride (\(HF\)) and carbon monoxide gas. Knowing how to quarantine a swollen phone or laptop without puncturing the pouch, how to cool a small device fire vs evacuating an e-bike battery fire, and where to dispose of damaged batteries legally prevents house fires and toxic inhalation.

Yenza oku ngoku

If you discover a swollen, overheating, hissing, or smoking lithium-ion battery in your home, vehicle, or office, execute these six steps immediately:

  1. If the battery is actively hissing, popping, emitting white/gray smoke, or smell of sweet chemical nail-polish remover, EVACUATE immediately: Do not try to pick up a hissing or smoking device with your bare hands; a pouch cell about to enter thermal runaway jets a 1,000°C (1,832°F) directional blowtorch flame within seconds of the first hiss. Get every person and pet out of the room, close the door behind you to contain toxic hydrogen fluoride smoke, and call your local emergency number (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom) via our amanani kaxakeka ulawulo.
  2. If the battery is swollen ("puffy") but cold and quiet, unplug the charging cable from the wall FIRST: Unplug the power adapter at the wall outlet rather than yanking tightly on a hot connector port attached to the swollen device. Never plug a swollen laptop or phone back in "just for ten minutes to back up photos," as charging voltage is the #1 trigger that turns a swollen pouch into an active fire.
  3. Power down the device gently without squeezing the screen or trackpad: If the screen responds, shut the device completely down so electrical current stops flowing through the stressed cell. Do not slam a swollen laptop lid shut or press down on a lifting phone glass screen to "snap it back into place," which can crush the internal separator and cause an instant short circuit.
  4. Never puncture, prick, or try to "vent the gas" out of a swollen battery: Never poke a swollen battery pouch with a pin, knife, or screwdriver to let the gas out, and never pry a glued-down swollen battery out of a phone frame using a metal flathead screwdriver or butter knife. Piercing the thin aluminum-laminate pouch shorts the anode and cathode together and exposes lithium compounds to moisture in the air, igniting an immediate jet flame into your face.
  5. Quarantine the cold swollen device outdoors in a metal container with dry sand: Wearing safety glasses and thick leather or work gloves, carry the powered-off device outdoors (never through a crowded hallway or elevator if hot) and place it on bare concrete, patio stone, or inside a metal bucket/cooking pot half-filled with dry sand, vermiculite, or non-clumping clay cat litter at least 3 meters (10 feet) away from walls, decks, and cars.
  6. If a small phone or tablet catches fire indoors and can be safely doused, flood it with massive volumes of water: Unlike grease fires (where water is forbidden) or solid metallic lithium-metal primary batteries, standard rechargeable lithium-ion electronics fires are suppressed by drenching with continuous gallons of water from a hose, sink sprayer, or water bucket to cool the cells below their 150°C (302°F) runaway threshold (only after unplugging from wall AC power). For large e-bike or scooter battery packs, do not fight the fire, evacuate immediately.

E-bike and e-scooter battery fires block exit doors in under 15 seconds

While a smartphone battery contains only 1 to 2 small pouch cells (roughly 10 to 18 watt-hours), an electric bicycle, e-scooter, or hoverboard battery pack contains 30 to 100+ cylindrical 18650 or 21700 cells wired together (500 to 1,000+ watt-hours). When one cell in an e-bike battery enters thermal runaway, it triggers a violent chain-reaction explosion across all adjacent cells, filling an apartment hallway with blinding black/white toxic smoke and launching flaming metal cell projectiles across the room in under 15 seconds. Never charge or store an e-bike, e-scooter, or hoverboard directly inside your apartment front doorway or only hallway exit, if it ignites while you are sleeping, it will cut off your only escape path.

How to recognize early warning signs of a failing lithium battery

Lithium-ion polymer (pouch) batteries and cylindrical cells give distinct physical, thermal, and olfactory warning signs days or weeks before catastrophic failure.

Device symptom and hazard level comparison table

Warning Symptom How It Looks or Feels on Your Device What Is Happening Inside the Battery Urgency & Required Action
1. Physical Swelling ("Spicy Pillow") Laptops: Trackpad becomes stiff and refuses to click; bottom aluminum case bows outward so the laptop rocks on a flat table; keyboard deck bulges upward. Phones/Tablets: Screen lifts along one edge showing a sliver of internal backlight; back glass cracks from inside out; white/purple pressure blotch appears in the middle of the LCD screen. Electrolyte decomposition (from over-discharge, heat, or aging) produces carbon dioxide (\(CO_2\)), carbon monoxide (\(CO\)), methane, and ethylene gas trapped inside the hermetic foil pouch. High (Non-Active): Unplug immediately, shut down, do not close the laptop lid or squeeze the phone, and take to a repair shop or hazardous waste facility for safe removal.
2. Abnormal Idle or Charging Heat The phone, power bank, or laptop bottom feels too hot to hold comfortably against the back of your hand (>50°C / 122°F) while just sitting idle or charging slowly. Microscopic metallic lithium dendrites (needle-like crystal whiskers) have grown across the internal polymer separator, creating an internal partial short-circuit that converts stored energy into heat. High: Unplug at the wall immediately, remove thick protective phone cases so heat can dissipate, place on a stone/tile surface away from fabrics, and never use the device again until the battery is replaced.
3. Sweet, Fruity, or Nail-Polish-Remover Odor You smell a distinct sweet, fruity, metallic, or acetone/ether chemical odor coming from the USB port, speaker grille, or battery compartment. Uxinzelelo lwerhasi lwangaphakathi lugqithise umda wokugqabhuka kwe-foil pouch seal, kwaye i-vaporized organic carbonate solvents (dimethyl carbonate, ethyl methyl carbonate) kunye ne-lithium hexafluorophosphate ($ LiPF_6 $) ziyavuza ngokusebenzayo. OKUBALULEKILEYO (Phambi koKulayita): Isingxobo sigqabhukile kwaye sikhupha umphunga otshayo. Khuphela isixhobo ngaphandle kwangoko usebenzisa iitongi/iiglavu ukuba zisapholile, khupha umoya kwigumbi, kwaye uhlale ucocekile.
4. I-Erratic Voltage Drops & Citdowns ngesiquphe Ipesenti yebhetri itsiba ukusuka kwi-65% ukuya kwi-12%, okanye isixhobo sifa ngequbuliso xa uvula ikhamera okanye i-app enzima nangona isalathiso sithi i-40% ihlawulwe. I-impedance ephezulu yangaphakathi (ukuchasana) kunye nokulahlekelwa kwee-ion ze-lithium ezisebenzayo ngaphakathi kweeseli ezonakalisiwe; ukutshaja le seli inyanzelisa i-lithium plating kwi-anode, inyusa ukukhula kwe-dendrite. Ephakathi: Cwangcisa ukutshintshwa kwebhetri kungekudala; kunqande ukushiya isixhobo siplagiwe singajongwanga ngobusuku.
5. Ukubetha, ukucofa, ukubethela umlozi, okanye umsi omhlophe Isandi esibukhali i-pop okanye i-aerosol ecinezelweyo hiss/whistle isandi esilandelwa ngumphunga oshinyeneyo omhlophe okanye ongwevu ophuma kumthungo. I-Active Thermal Runaway: Ubushushu bangaphakathi budlule kwi-130°C ukuya kwi-150°C (266°F ukuya kwi-302°F); isahluli sinyibilikile, kwaye i-jet flame ye-1,000 ° C iya kuqhuma phakathi kwe-2 ukuya kwi-10 imizuzwana. ** INKXASEKO EBUBONGE UBOMI**: Yihla / hamba ngokukhawuleza, uphume kwigumbi, uvale umnyango, kwaye ufowunele 911 / 112 / 999.

Ifiziksi kunye nekhemikhali ye-thermal runaway (Kutheni imililo ye-lithium-ion yodwa)

Ukuqonda ukuba kutheni umlilo we-lithium-ion uziphatha ngendlela eyahlukileyo kwinkuni, ephepheni, okanye kwigrisi yomlilo ekhitshini kucacisa ukuba kutheni iindlela eziqhelekileyo zokucima umlilo zisilela:

  1. **Inqanaba loku-1: I-SEI Layer Breakdown (80 ° C ukuya kwi-120 ° C / 176 ° F ukuya kwi-248 ° F) **: Ngaphakathi kweseli ye-lithium-ion enempilo, ifilimu ehamba nge-microscopic ebizwa ngokuba yi- **Solid Electrolyte Interphase (SEI) ** inxibe i-graphite anode. Ukuba ibhetri ihlanjululwe, ityunyuziwe, ihlawuliswe kakhulu, okanye ishiywe kwideshibhodi yemoto evuthayo, amaqondo okushisa adlula i-80 ° C kunye ne-sei ekhuselayo ye-SEI iyancibilika, ibangele ukusabela kwe-exothermic phakathi kwe-lithium-intercalated anode kunye ne-solvent organic liquid.
  2. **Inqanaba le-2: I-Polymer Separator Meltdown (130 ° C ukuya ku-150 ° C / 266 ° F ukuya ku-302 ° F) **: Iphepha elincinci elincinci le-polyethylene / i-polypropylene inwebu (kuphela i-12 ukuya kwi-25 ye-microns engqindilili, incinci kune-plastic wrapper) kuphela komqobo othintela ukuthintela kunye ne-anode epheleleyo. Kwi-135 ° C (275 ° F), esi sahluli seplastiki siyanyibilika ngokupheleleyo, sibangele isiphaluka esifutshane sangaphakathi esipheleleyo.
  3. **Inqanaba le-3: Ukukhutshwa kwe-Oxygen ye-Cathode kunye nokuZigcina ngokuBaleka (180 ° C ukuya kwi-1,000 ° C / 356 ° F ukuya kwi-1,832 ° F) **: Njengoko ubushushu bugqithisa kwi-180 ° C, i-metal-oxide cathode (efana ne-Lithium Cobalt Oxide, i-Ncombalt MC, i-Nickel ye-Nickel okanye i-Ncomba kwaye ikhupha ioksijini ecocekileyo yemolekyuli (\(O_2\)) ngaphakathi kweseli etywiniweyo. Ngenxa yokuba ibhetri ngoku iqulethe i-oksijini yayo yangaphakathi + i-fuel ye-solvent ye-hydrocarbon evuthayo + i-500 ° C yomthombo wokuvutha, iqhuma ibe yidangatye lokuziphakela.
    • **Kutheni ukutshaya kungayiyeki impendulo **: Nokuba ungcwaba ibhetri ye-lithium-ion ebalekayo phantsi kwengubo yomlilo, ugwebu, iCO2, okanye isoda yokubhaka, iseli iyaqhubeka nokusabela kwayo ngemichiza ephumayo ngaphakathi kwimfumba de kusetyenziswe amandla ayo ombane kunye neekhemikhali agciniweyo, kunye nomzuzu wokuphakanyiswa kwengubo, igesi evuthayo evuthayo kunye negesi enokutsha iphinde ikhanyise.
  4. Inqanaba lesi-4: I-Toxic Hydrogen Fluoride (\(HF\)) I-Off-Gassing: Ityuwa ye-electrolyte esetyenziswa phantse kuzo zonke iibhetri ze-lithium-ion zorhwebo yi Lithium Hexafluorophosphate (\(LiPF_6\)). Xa ibonakaliswe emlilweni kunye nokufuma, ibola ibe yi- Hydrogen Fluoride (\(HF\)) gas (ejika ibe yi-corrosive Hydrofluoric Acid xa ibamba ucweyo olufumileyo lwemiphunga yomntu kunye ne-corneas), kunye ne-phosphoryl fluoride (\(POF_3\)), i-carbon mondeoxide (\(POF_3\)), i-carbon $ HC \(), i-carbon mondeoxide (i-\) HC). Ukuphefumla kwanemiphunga embalwa yomsi oshinyeneyo webhetri emhlophe kwigumbi elivaliweyo kunokubangela umonakalo obulalayo wekhemikhali wemiphunga kunye nenkqubo yetyhefu yefluoride.

Indlela yokucima okanye uqulethe umlilo we-lithium-ion ngokukhuselekileyo

Uvavanyo lwenkonzo yomlilo nguMbutho woKhuseleko loMlilo weSizwe (i-NFPA), i-UL Solutions (UL 9540A), kunye ne-Federal Aviation Administration (FAA) iseka iiprothokholi ezicacileyo ze-electronics ezincinci zabathengi vs iipakethi ezinkulu zokuhamba.

Ukulinganisa indlela yokucima umlilo: I-Lithium-Metal vs Lithium-Ion

Intsomi exhaphakileyo kwi-intanethi ithi * "Akufuneki ubeke amanzi kwifowuni okanye kwi-laptop yebhetri yomlilo ngenxa yokuba i-lithium iqhuma emanzini." * Loo ntsomi iyabhidekisa ** iibhetri ze-lithium-Metal eziphambili ezingahlawulekiyo ** (eziqulethe i-elemental elemental metallic lithium foil) kunye ** ne-Lithium-Ion etshajwayo kwakhona kwiibhetri ze-lithium-Ion kwi-lithium edibeneyo ye-lithium efakwe kwi-lithium edibeneyo ye-lithium edibeneyo, i-lithium edibeneyo yesinyithi igraphite kunye neeoksidi zetsimbi).

I-Agent yoxinzelelo ILithium-Ion encinci eTshajwayo yoMlilo (Ifowuni, iThebhulethi, iLaptop, iBhanki yaMandla) I-E-Bike enkulu / i-E-Scooter / i-EV yeBattery Pack yoMlilo Kutheni Isebenza okanye Isilela
Umthamo wamanzi omninzi (Ithumbu lasegadini, isitshizi sokutshiza, iiemele zamanzi) EYONAYO / IYANIKEZWA YI-FAA & NFPA (Emva kokuba ikhutshiwe kumandla odonga lwe-AC). Ifuna imibhobho yomcimi-mlilo ephuma ngamandla (amawaka eelitha) ukusuka ngaphandle; musa ukuzilwela. Amanzi kuphela kwe-arhente yendlu eqhelekileyo enomthamo wobushushu obuphezulu ngokwaneleyo uku-pholisa iiseli zebhetri ngaphantsi kwe-130°C* kunye nokunqanda ubushushu ekutsibeni ukusuka kwiSeli #1 ukuya kwiSeli #2. Qaphela: Sebenzisa iigaloni eziqhubekayo zamanzi, ungaze ube nokutshiza okuncinci.
Isicimi-mlilo se-ABC esineMichiza eyomileyo (Isixhobo sokucima umlilo esikwikhaya elibomvu esiqhelekileyo) Iluncedo ngokuyinxenye kwiikhethini ezijikelezileyo/ikhaphethi, kodwa AYISAYI kumisa ibhetri ngokwayo ekubeni ilayite kwakhona. Ayisebenzi kwipakethi yebhetri; ipakethe iya kuqhushumba ngokutsha imizuzwana emva kokuba umgubo ucinyiwe. I-ABC monoammonium phosphate powder itshisa amadangatye kumandlalo ovuthayo okanye kwiplastiki yedesika ejikeleze ifowuni, kodwa ayinayo impembelelo yokupholisa **, ngoko ke ibhetri ye-600 ° C ihlala ngaphezu kobushushu obubalekayo kwaye iphinde ivuthe.
CO2 okanye iHalotron Extinguisher Iwisa ilangatye langaphandle okomzuzwana, emva koko kwangoko livuthe kwakhona. Ayisebenzi. Isusa umoya wangaphandle ngokufutshane, kodwa ayipholisi impendulo yeseli yangaphakathi.
Ukuntywila kwi-emele yentsimbi yamanzi (iPost-Fire) ** Isinyanzelo emva kokuyeka amadangatye ** (untywilise ngaphandle kwiiyure ezingama-24+). Abacimi-mlilo bantywilisela iipakethi ezitshisiweyo ze-e-bike kwiidrum ezikhethekileyo zamanzi/zevermiculite. Ithintela ukulibaziseka ukuvutha kwakhona (amandla obushushu axineneyo kwiiseli ezingabamelwane anokubangela ukuba ilaptop etshisiweyo okanye ibhanki yamandla iqhume emva kwedangatye kwiiyure ezi-2 ukuya kwezili-12 emva kokuvela "ngaphandle").
Intlabathi eyomileyo / iVermiculite / ingubo yoMlilo Ilungele i-quarantine yothintelo yebhetri ebandayo edumbileyo, okanye ukukhusela kwiintlantsi eziphaphazelayo ngelixa usuka kude. Kuyingozi ukuba ingubo yomlilo iphoswe ngokuqinileyo phezu kwebhetri ye-e-bike ekhupha umoya ngaphakathi. Uvavanyo lweNkonzo yoMlilo lubonisa ukuphosa ingubo yomlilo enzima phezu kwebhetri ye-e-bike esebenzayo ibamba ilifu elikhulu le-hydrogen eqhumayo engatshiswanga kunye negesi ye-hydrocarbon phantsi kwengubo, idala i- **umphunga-ilifu lokuchithwa kwebhombu ** xa i-oksijini ingena.

Iprotocol yeFAA "Cool and Submerge" yomlilo wesixhobo esincinci

Xa i-smartphone, ithebhulethi, okanye ipeni yevape ibamba umlilo ngaphakathi kwikhabhinethi yenqwelomoya, abalindi benqwelomoya baqeqeshwa yiFederal Aviation Administration (FAA) ukwenza ulandelelwano oluthile olunamanyathelo amathathu (onokuthi ulungelelanise ekhaya ** kuphela ukuba isixhobo sincinci, singafakwanga, kwaye unokukuphepha ukuphefumla umsi **):

  1. Inyathelo loku-1: Khupha kwaye uwise amadangatye ajikelezileyo: Ukuba isixhobo siqhagamshelwe kwindawo ephuma eludongeni, khupha intambo eludongeni (okanye uvale i-breaker sekethe) ukuze kungabikho mbane wekhaya we-120V/230V AC ukhoyo. Ukuba iphepha okanye izinto zokulala ezikufutshane ziye zatsha, wisa umlilo wegumbi ngesixhobo sokucima i-ABC okanye amanzi.
  2. Inyathelo lesi-2: Gxilisa rhoqo ngamanzi ukupholisa umbindi webhetri: Galela ingqayi, iemele, okanye umjelo wamanzi oqhubekayo ngqo kwifowuni evuthayo okanye ilaptop ukusuka kubude bengalo (ungaze ube ngamagaqa omkhenkce, akhusela ubushushu endaweni yokuba aqukuqelele kwibhokisi). Lindela ukufutha kunye nomphunga njengoko amanzi ebetha i-600 °C kwi-casing yesinyithi; qhubeka ugalela amanzi de kuphele ukutshaya nokufutha.
  3. Inyathelo lesi-3: Shiya ungaphazamisekanga kangangemizuzu eli-15, emva koko uye ngaphandle kwibhakethi entywilweyo/yentlabathi: Lindela imizuzu eyi-10 ukuya kwe-15 ukuze iiseli ziphole, emva koko sebenzisa intsimbi ende yebarbecue okanye ifosholo neeglavu ezishinyeneyo ukubeka isixhobo esitshisiweyo kwibhakethi yentsimbi ezaliswe ngamanzi okanye isanti emanzi okanye emanzi rhoqo- **ngaphandle kwezindlu kunye neebhanki rhoqo- **ukutshisa kwakhona iiyure emva koko **.

Enye indlela ekhuselekileyo yekhemistri yebhetri: LiFePO4 (iLithium Iron Phosphate)

Xa uthenga izikhululo zamandla eziphathwayo ezinkulu ("ijenereyitha zelanga" zokucima umbane ekhaya) okanye iibhetri zokushukuma ezitshintshileyo, khangela iiyunithi ezakhiwe nge LiFePO4 (Lithium Iron Phosphate / LFP) iiseli kuneeseli ze-NMC/LiPo lithium-ion. Ngenxa yokuba ibhondi ye-phosphorus-oxygen covalent kwi-LiFePO4 cathode yomelele kakhulu kune-cobalt-oxide bond, iibhetri ze-LiFePO4 zinomgangatho obalekayo we-thermal phantse ** 100 ° C phezulu (malunga ne-270 ° C / 518 ° F)** kwaye musa ukukhulula igesi ye-oksijini ekhawulezayo xa igcinwe ngokugqithisiweyo kwisitoreji sasekhaya.

Uvalelo olukhuselekileyo kunye nokulahlwa kwebhetri edumbileyo ("i-spicy pillow")

Ukuba uvula idrowa yedesika kwaye ufumane i-smartphone endala, i-PSP/Nintendo ephathwayo, iMacBook, okanye ibhanki yamandla ye-USB enebhetri ekhukhumele njengomqamelo, ungothuki. Ibhetri ebandayo, ephumleyo edumbile ehleli edroweni ayizukugqabhuka kwimizuzwana elishumi ezayo ngaphandle kokuba uyiwise, uyigqobhoze, okanye uyiplage kwitshaja.

Inyathelo ngenyathelo lokuvalelwa kunye nesikhokelo sothutho

  1. Sukuzama ukususwa kwebhetri ye-DIY kwifowuni okanye ithebhulethi encamatheleyo edumbile: Ii-smartphones zala maxesha, ii-iPads, kunye neelaptops ezibhityileyo zincamathelisa izingxobo zebhetri yefoil ethambileyo ngokuthe ngqo kwisakhelo sealuminiyam eneethebhu zokuncamathelisa ezomeleleyo. Xa ibhetri idumbile, ulusu lwayo lwe-foil loluliwe ngephepha-lincinci phantsi koxinzelelo lwegesi; ukuzama ukuyikhupha kwincamatheliswa ngespudger, ikhadi letyala, okanye umpu wobushushu ugoba isingxobo esidumbileyo kwaye sibangela ukuba sigqabhuke sibe ngamadangatye kanye kwibhentshi yakho yokusebenza. Shiya ibhetri edumbileyo ngaphakathi kwesixhobo sentsimbi (okanye thatha isixhobo sisonke usise kwibar yenkonzo egunyaziswe ngumvelisi njengeApple Store okanye uBreakiFix exhotyiswe ngeebhakethi zesanti ezithintela umlilo).
  2. Iteyiphu iitheminali zentsimbi eziveziweyo: Ukuba yipakethi yebhetri esuswayo, gquma iipadi zombane zegolide/zekopolongeteyiphu yokupakisha ecacileyo okanye iteyiphu yombane engeyiyo ekuqhubeni (ungaze uyivale ngentsimbi).
  3. Pakisha kwi-emele eyodwa yesanti/i-vermiculite de ube uqhuba ukuya kwindawo yokulahla: Beka isixhobo sicaba ngaphakathi kwembiza yentsimbi okanye i-emele ebhediweyo ngeesentimitha ezi-5 (ii-intshi ezi-2) zesanti eyomileyo, i-kitty litter, okanye i-vermiculite, kwaye uyibeke ngaphandle kwindawo enomthunzi, ekhuselwe yimvula kude nesanti enokutsha. Xa uyiqhubela kwindawo yenkunkuma eyingozi, beka iemele yentsimbi kwibhedi yakho okanye kwibhedi yelori enefestile ekrazukileyo.
  4. Uya kuyisa phi ibhetri edumbileyo okanye eyonakeleyo (UNGAZE uthabathe imigqomo yebhetri eqhelekileyo):
    • Kutheni ungenako ukuwisa ibhetri edumbileyo kwikhadibhodi eqhelekileyo "Ibhokisi yokuBhalisa iBattery Recycling" kwivenkile enkulu: Iityhubhu eziqhelekileyo zokuqokelelwa kwekhadibhodi ezingajongwanga kwiivenkile zegrosari okanye kwiindawo zokusebenzela zaseofisini kuphelazeziibhetri ezingonakaliswanga. Ukuwisa isingxobo se-lithium esidumbileyo okanye esonakeleyo kwibhokisi yekhadibhodi ezele ezinye iibhetri zentsimbi kunokutshisa ivenkile.

Ukuthintela ukusilela kwebhetri ye-lithium-ion ekhaya

Landela le mikhwa mithandathu yemihla ngemihla ecetyiswa yi-UL Standards & Engagement kunye neNational Fire Protection Association (NFPA) ukunqanda ukudumba kwebhetri kunye nemililo:

  • Ungaze uhlawulise iifowuni, iitafile, okanye iivapes phantsi komqamelo wakho, ebhedini yakho, okanye ngaphakathi kweekhushini zesofa: Ukutshaja kusoloko kuvelisa ubushushu; ukungcwaba ifowuni yokutshaja phantsi komqamelo okanye ingubo ibamba i-100% yolo bushushu kuze kube yilapho ibhetri ifikelela kwiqondo lokushisa lokutshatyalaliswa kwe-thermal ngelixa ulele. Soloko uhlawulisa izixhobo kwitafile eqinileyo, esicaba, engatshiyo okanye kwindawo yokulala ebusuku.
  • Thenga kuphela izixhobo ze-UL-Certified (UL 2849 yeebhayisekile, UL 2272 yeehoverboards/scooters, UL 2056 yeebhanki zamandla): Ngaphezu kwe-90% yomlilo obulalayo webhayisekile ye-e-bhayisekile kunye nesikuta kubandakanya iibhetri ezingaqinisekiswanga zasemva kwentengiso, iibhetri ezihlaziyiweyo ezihlaziyiweyo, iipakethi zeseli ezihlaziyiweyo ezithengwe ngexabiso eliphantsi leebhetri ze-intanethi ezithengwe ngexabiso eliphantsi lesithathu (BMS) iisekethe zokucutha amandla angaphezulu kwe-voltage.

Imibuzo ebuzwa qho

If I carefully poke a tiny pinhole in a swollen phone battery outdoors, will it let the gas out so I can keep using it?

**NO, never do this under any circumstances.** First, the gas inside a swollen battery is flammable hydrocarbon and carbon monoxide vapor mixed with toxic hydrofluoric acid precursors. Second, the swollen pouch is not an empty air pocket on top of the battery; the gas is trapped *between* the tightly wound microscopic layers of anode, separator, and cathode foil. Pushing a needle or pin even 1 millimeter through the outer pouch pierces those live energized layers together, creating an immediate dead short-circuit that shoots a 1,000°C jet of flame and molten metal out of the hole you just made. Even if it did not immediately catch fire, moisture from the outside air entering the pinhole reacts with the lithium salts to form hydrofluoric acid and destroys the cell.

Will putting a swollen battery in the refrigerator or freezer make the gas contract and fix the swelling?

**No.** Putting a swollen lithium-ion battery in your kitchen refrigerator or freezer is both ineffective and dangerous. While cold temperatures temporarily reduce gas volume slightly according to the ideal gas law, the chemical breakdown inside the battery is permanent and irreversible. Worse, placing a volatile, compromised battery containing toxic fluorophosphate solvents next to your family's food risks chemical contamination if the pouch leaks, and the condensation that forms on the battery when you pull it out of the cold freezer shorts out the external BMS circuitry and triggers fire when it warms back up.

Why did my old laptop or phone battery swell up sitting in a drawer when it hadn't been plugged in for two years?

Lithium-ion batteries do not only swell from overcharging; they also swell from **deep over-discharge during long-term storage**. Every lithium-ion battery self-discharges by a few percent each month even when turned off. If you put a phone or laptop into a drawer with only 10% battery and leave it for a year or two, the cell voltage drops below the critical threshold of **2.0 to 2.5 volts**. At that ultra-low voltage, the internal SEI layer breaks down and the copper current-collector foil begins dissolving into the electrolyte, generating hydrogen and carbon dioxide gases that puff the pouch up like a pillow even with zero external electricity applied.

What should I do if my phone slips down inside the crack of a motorized reclining couch or an airplane business-class seat?

**Do NOT press the motorized seat control button and do NOT force a manual recliner handle.** High-torque electric motors and steel scissor-mechanisms inside reclining living-room sofas, massage chairs, adjustable beds, and airline business-class seats exert hundreds of kilograms of shearing force. If a smartphone is wedged in the folding steel hinge and you move the seat, the metal frame bends and crushes the phone in half, instantly puncturing the lithium-ion battery and igniting the polyurethane foam cushions of the couch or aircraft cabin. On an airplane, **push your flight attendant call button immediately** without moving the seat; at home, unplug the motorized recliner from the wall first and look underneath with a flashlight to lift the phone out by hand.

Is it safe to buy a "LiPo Safe Fireproof Bag" to store or charge e-bike, drone, or RC car batteries?

Fiberglass-woven **LiPo Safe Bags** and metal ammunition cans (with the rubber lid gasket removed so the ammo can does not turn into a sealed pressure bomb) are helpful for **small RC hobbyist and drone battery packs (under 100 watt-hours)** because they contain flying sparks and reduce radiant flame spread long enough for you to grab a hose or evacuate. However, **independent fire tests show that thin zippered fabric LiPo bags often rupture, blow open at the zipper, or burn through when tested with large 500-to-1,000-watt-hour e-bike or scooter batteries**, and they do **not** filter out lethal hydrogen fluoride smoke. Never let a "fireproof bag" give you a false sense of security to charge a damaged or uncertified battery indoors overnight.

What should I do after a small battery fire in my home is out, how do I clean up the white powder and soot safely?

Never sweep or vacuum the white/black soot and chemical residue left behind by a burned lithium-ion battery without protective gear, and never touch the crusty residue around a ruptured cell with bare hands. The residue contains corrosive **lithium hydroxide, hydrofluoric acid salts, and toxic heavy-metal oxides (cobalt, nickel, manganese)**. First, ventilate the room thoroughly with open windows and fans blowing *outward* for several hours. Put on **thick nitrile rubber gloves, wrap-around eye goggles, long sleeves, and an N95/P100 particulate respirator**. Wipe hard surfaces using disposable wet paper towels dampened with water and mild detergent (never dry-sweep or use a standard household vacuum, which blows toxic dust into the air), seal all rags and burned debris inside heavy-duty double plastic bags inside a sealed bucket, and dispose of them through your municipal **Household Hazardous Waste (HHW)** center. Discard any porous items (pillows, clothes, mattresses, or food) that were exposed to the dense white battery smoke.
