Ukusukela ukuba i-IPHONE8 idweliswe ngaphezulu kwenyanga, inani leengozi ezenzeke ngenxa yebhetri zenzeka, ezikhokelela kwiingozi zesikrini kunye ne-fuselage. Ngokujonga isiganeko sokudubula kwe-Samsung Note7 kunyaka ophelileyo, ukhuseleko lwebhetri ngokukodwa luvumela abathengi ukuba bathathele ingqalelo, kwaye njengebhentshi kushishino lweefowuni eziphathwayo, isiganeko salo nyaka se-iPhone8PLUS se-bulge yebhetri sisavundiswa, ukuba i-iPhone8 elandelayo yefowuni iyaqhubeka isenzeka kwiNgozi enkulu, iya kubangela imiphumo eyintlekele kwi-Apple. Ke kwimeko yefowuni, ngaba iidramu zebhetri? Umgqomo webhetri awukho ngaphezu kweekhemikhali kunye neempendulo ze-electrochemical, ezinokukhuselwa kwibhloko yangaphakathi ngaphakathi.

Ukusuka kwizinto ezibangelayo, zinokwahlulwa zibe zizizathu zangaphandle kunye nezizathu zangaphakathi, kwaye izizathu zangaphandle zibandakanya i-battery overgemic, i-over-discharge, i-short circuit, i-extrusion collision, i-Environment yokugcina, njl. 1 Intlawulo engafanelekanga kunye nokuphuma kubangele ukuba ibhetri itshaje okanye ngaphezulu.

Emva kokuba ibhetri ihlajiwe, iyakutshajwa ukuba ibhetri ihlajiwe. Ngexesha lokukhutshwa kwebhetri, ukukhutshwa kusaqhubeka xa i-voltage yokukhupha ifikelela kwi-battery discharge, ebizwa ngokuba yi-over discharge. Ukugqithisa okanye ukugqithiswa kuya kutshabalalisa isakhiwo sangaphakathi seseli, okubangela ukuba i-polarization enzima yesibonda, kunye nokubola kwefilimu ye-SEI, i-electrolyte, njl.

kunye nerhasi. Xa ibhetri ye-lithium ion isenzeka, i-ion ye-lithium engaphezulu ikhutshwa kwi-electrode esebenzayo into esebenzayo, kwaye i-electrode crystal structure iyatshatyalaliswa, kwaye i-oksijini inokwenzeka kakhulu, kwaye isinyithi se-lithium sifakwe kumphezulu we-carbon negative electrode material, yenze i-lithium metal dendritic crystal. Le crystal ye-dendritic ilula ukugqobhoza i-membrane yombane, ibangela i-micro-short circuits yangaphakathi, kukho umthamo omkhulu wamandla okushisa, oye wakhuthaza ukusabela kweekhemikhali zangaphakathi, okukhokelela ekuqhumeni, kunye nokuqhuma komlilo.

I-2 yokugcina engafanelekanga okanye ukusetyenziswa kweemekobume. Ibhetri ye-lithium ion ibuyisela i-electrochemical reaction ye-compound yangaphakathi ukuguqula amandla ekhemikhali kumandla ombane, kwaye ukusabela kweekhemikhali kuya kuchaphazeleka bubushushu, iqondo le-reactivity yecala kunye nemveliso yokuphendula ihambelana nobushushu. Xa ibhetri igcinwe okanye isetyenziswe kwindawo yokushisa ephezulu, ifilimu ye-SEI ngaphakathi kwebhetri ichithwa ngenxa yokushisa okuphezulu, kwaye ukubola kuya kusabela ngokwekhemikhali nge-electrode efanelekileyo kunye ne-electrode engafanelekanga.

Ngokukodwa, xa ibhetri ingaphezu kweqondo lokushisa elicetyiswayo, umatshini webhetri osebenzayo uya kukhulula inani elikhulu le-lithium ion. Xa i-lithium ion ikhutshwa, ukuzinza kwesakhiwo se-crystal kuya kutshabalalisa ukuzinza kwesakhiwo se-crystal, kwaye ukhuseleko lwebhetri luyancipha. 3 Ukusetyenziswa kakubi koomatshini bebhetri.

Impembelelo okanye i-extrusion yindlela eqhelekileyo yokubangela ukulahleka kobushushu ngoomatshini, okunokubangela umonakalo kwisakhiwo sebhetri kunye nomsebenzi wepleyiti yokukhusela. Ibangela iisekethe ezimfutshane zangaphakathi okanye zangaphandle kwibhetri. Ukonakala komatshini webhetri ngokuqhelekileyo kwenzeka kwixesha elifutshane, kwaye isakhiwo sebhetri sitshatyalaliswa ngoomatshini, okubangela ukuba i-thermal ingalawuleki.

Ukuba ipleyiti yokukhusela ibhetri yonakalisiwe, ibhetri kunokwenzeka ukuba izaliswe ngokugqithisileyo kwimeko yokungabikho kokhuseleko. 4 Umzi-mveliso webhetri unenkqubo yokuvelisa. Ukuba ingundoqo ixutywe ngamasuntswana othuli ngaphakathi kwiseli yebhetri, inkulu kakhulu, inxeba alilingani, kwaye ukugquma okungalinganiyo akulingani kuya kubangela ibhetri ye-lithium-ion ngokwayo, eyingozi ekhuselekileyo efihliweyo kwiibhetri ze-lithium ion.

Le ngxaki yomgangatho inokubangela i-micro short circuits yangaphakathi, kwaye inkqubo yangaphakathi encinci ye-micro-short yebhetri inokucotha, asiyi kukwazi ukuvavanya ibhetri xa ibhetri iya kwenzeka. 5 Iziphene zokuyila ibhetri engundoqo, kubandakanywa amandla epalini angalunganga, ukwenzela ukunciphisa umthamo webhetri, i-diaphragm isetyenzisiweyo, i-design ye-septum margin ayihlukanga ngokupheleleyo, i-pole kunye ne-pali engalunganga, indlebe ayilwanga, i-tape yokukhusela, njl. Uyilo lwebhetri alubonakali kwixesha elidlulileyo, kwaye ibhetri ibangelwa yizinto ezahlukeneyo zangaphandle, ngenxa yezinto ezahlukeneyo zangaphandle ezifana nesakhiwo sefowuni ephathwayo, kukho izinto ezahlukeneyo zangaphandle ezibangelwa yi-extrusion yesakhiwo sefowuni.

I-Deposition, i-internal micro short circuit, njl., iya kubangela amagubu ebhetri, kunye nokudubula komlilo. Okwangoku, ibhetri esisiseko yefowuni yefowuni yenzelwe imisebenzi yokukhusela eyisiseko efana nokugqithiswa, ukugqithiswa, isiphaluka esifutshane, kwaye olu hlobo lomsebenzi wokukhusela lunzima ngokubanzi, ngoko ke ifowuni isetyenziswe kwiimeko eziqhelekileyo kunye nezifanelekileyo.

, Umlilo okanye ugqabhuko-dubulo. Nangona kunjalo, abaninzi abavelisi balandela izikrini zomphezulu, iimpawu ezingaphezulu, ukusebenza okuphezulu kunye noyilo lwefowuni ephathwayo elula, ngelixa uphucula umthamo webhetri, ukucofa rhoqo indawo yebhetri, okubangela ukuba iziphene zokuyila ibhetri zibe yingozi kakhulu yokhuseleko, kancinane Ukungaqondi kunokubangela iingozi zokhuseleko ezifana nokuqhuma kwebhetri. Isishwankathelo, igubu lebhetri liyingozi kakhulu kwaye alizinzile.

Ukuba kuphuhliso lwale meko, kulula ukubangela ukuba ibhetri ye-thermal ingalawuleki, kwaye ibhetri iphukile, i-electrolyte iphuphuma, kunye nomlilo onzima, ukuqhuma. Ukuba umsebenzisi udibana nesigubhu kwibhetri yeselula, ifowuni ephathwayo kufuneka imiswe ngokukhawuleza, kwaye uqhagamshelane nefowuni yeselula emva kokuthengiswa kwesebe lokulungisa indawo. Iingcebiso zithintela njani iidramu zebhetri: 1, zama ukusebenzisa itshaja yokuqala ukutshaja, ungasebenzisi itshaja engeyiyo yokuqala.

2, musa ukuvumela ifowuni yakho iqhubeke nokuqhagamshelwa kwitshaja. 3. Thintela iifowuni eziphathwayo kwiindawo ezigqithisileyo.

Qinisekisa ukuba ifowuni yakho okanye ibhetri ihlawuliswe kwaye isetyenziswe phantsi kwendawo efanelekileyo yokushisa, musa ukugcina ifowuni yakho kwindawo yelanga ngqo, imoto eshushu, njl. 4. Ukuba ufumana igubu lebhetri okanye enye impazamo, kufuneka uyibuyisele kwangethuba.
