Kuyini ukuqonda kwakho ngokunwetshwa kwebhethri le-iPhone 8?

ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - Mea Hoolako Uku Uku

Njengoba i-IPHONE8 ibalwe isikhathi esingaphezu kwenyanga, inani lezingozi ezenzeke ngenxa yebhethri liyenzeka, okuholela ezingozini zesikrini ne-fuselage. Uma kubhekwa isigameko sokuqhuma kwe-Samsung Note7 ngonyaka odlule, ukuphepha kwebhethri kuvumela ikakhulukazi abathengi ukuthi banake, futhi njengesilinganiso embonini yezingcingo eziphathwayo, isigameko salo nyaka sokuqhunyiswa kwebhethri le-iPhone8PLUS sisavutshelwa, uma uchungechunge olulandelayo lwe-iPhone8 umakhalekhukhwini uqhubeka ukwenzeka eNgozini enkulu, kuzodala imiphumela eyinhlekelele ku-Apple. Ngakho-ke esimweni sefoni, ingabe izigubhu zebhethri zizoba? Isigubhu sebhethri asiyona into edlula ukusabela kwamakhemikhali kanye ne-electrochemical, okungavikelwa kubhulokhi yangaphakathi ngaphakathi.

Kusuka kuzici ezibangela, ingahlukaniswa ngezimbangela zangaphandle kanye nezimbangela zangaphakathi, futhi izimbangela zangaphandle zihlanganisa ibhethri eligcwele i-overgemic, ukukhishwa ngokweqile, i-short circuit, ukushayisana kwe-extrusion, indawo yokugcina, njll;. 1 Ukushaja okungalungile nokukhipha okungalungile kubangele ibhethri phezu kokushajwa noma ngaphezulu.

Ngemva kokuba ibhethri selishajwe, izoshajwa uma ibhethri selishajwe. Ngesikhathi sokukhishwa kwebhethri, ukukhishwa kusaqhubeka lapho i-voltage yokukhipha ifinyelela ekuphumeni kwebhethri, okubizwa ngokuthi ukukhishwa ngokweqile. Ukushajwa ngokweqile noma ukugqagqana kuzolimaza ukwakheka kwangaphakathi kweseli, okuholela ekuhlukanisekeni okukhulu kwesigxobo, futhi kubole ifilimu ye-SEI, i-electrolyte, njll.

kanye negesi. Lapho ibhethri ye-lithium ion yenzeka, i-lithium ion eyeqile ikhishwa entweni esebenzayo ye-electrode, futhi isakhiwo sekristalu ye-electrode enhle siyabhujiswa, futhi umoya-mpilo kungenzeka kakhulu, futhi insimbi ye-lithium ifakwa ebusweni bezinto ze-carbon negative electrode, zenze ikristalu ye-lithium metal dendritic. Le crystal ye-dendritic kulula ukubhoboza i-membrane kagesi, okubangela ama-circuits angaphakathi amancane amancane, kukhona inani elikhulu lamandla okushisa, okuye kwakhuthaza ukusabela kwamakhemikhali kwangaphakathi, okuholela ekuqhumeni, ngisho nokuqhuma komlilo.

2 indawo yokugcina engalungile noma izindawo zokusebenzisa. Ibhethri ye-lithium ion ihlaziya ukusabela kwe-electrochemical kwenhlanganisela yangaphakathi ukuguqula amandla amakhemikhali abe amandla kagesi, futhi ukusabela kwamakhemikhali kuzothinteka izinga lokushisa, izinga lokuphinda lisebenze ohlangothini kanye nomkhiqizo wokusabela kuhlobene nezinga lokushisa. Uma ibhethri ligcinwa noma lisetshenziswa endaweni yokushisa ephezulu, ifilimu ye-SEI engaphakathi kwebhethri iyabola ngenxa yezinga lokushisa eliphezulu, futhi ukubola kuzosabela ngokwamakhemikhali nge-electrode ephozithivu kanye ne-electrode engalungile.

Ikakhulukazi, uma ibhethri lingaphezu kwebanga lokushisa elinconywayo, umshini webhethri osebenzayo uzokhipha inani elikhulu lama-ion e-lithium. Lapho i-lithium ion ikhishwa, ukuzinza kwesakhiwo se-crystal kuzobhubhisa ukuzinza kwesakhiwo se-crystal, futhi ukuphepha kwebhethri kuyancipha. 3 Ukusebenzisa kabi ibhethri ngemishini.

Umthelela noma i-extrusion kuyindlela evamile yokuqalisa ukulahlekelwa ukushisa, okungase kubangele umonakalo esakhiweni sebhethri kanye nomsebenzi wepuleti lokuvikela. Idala amasekethe amafushane angaphakathi noma angaphandle ebhethrini. Ukulimala komshini webhethri ngokuvamile kwenzeka esikhathini esifushane, futhi isakhiwo sebhethri sonakaliswa ngomshini, okubangela ukungalawuleki kwe-thermal.

Uma umsebenzi wepuleti lokuvikela ibhethri lonakele, ibhethri maningi amathuba okuthi ligcwale ngokweqile uma kungekho ukuvikeleka. 4 Imboni Yebhethri inenqubo yokukhiqiza. Uma umgogodla uxubene nezinhlayiya zothuli ngaphakathi kweseli yebhethri, likhulu kakhulu, isilonda asilingani, futhi ukumbozwa okungalingani kungalingani kuzoholela ebhethri ye-lithium-ion ngokwayo, okuyingozi efihliwe ephephile yamabhethri e-lithium ion.

Le nkinga yekhwalithi ingase ibangele ama-micro short circuits angaphakathi, futhi inqubo yangaphakathi ye-micro-short yebhethri ingase ihambe kancane, ngeke sikwazi ukuhlola ibhethri uma ibhethri lizovela. 5 Amaphutha edizayini yomgogodla webhethri, okuhlanganisa ukusebenzisa amandla ensimbi angemahle, ukuze kwehliswe umthamo webhethri, i-diaphragm isetshenziswa, idizayini ye-septum margin ayihlukanisiwe ngokuphelele, isigxobo esihle nesinegethivu, indlebe ayiklanywanga, itheyiphu evikelayo, njll. Idizayini yebhethri ayitholakali ngempela esikhathini esidlule, futhi ibhethri ibangelwa izici ezihlukahlukene zangaphandle, ngenxa yezinto ezihlukahlukene zangaphandle ezifana nesakhiwo seselula, kunezici ezihlukahlukene zangaphandle ezibangelwa i-extrusion yesakhiwo seselula.

Ideposition, i-micro short circuit yangaphakathi, njll., izodala izigubhu zebhethri, ngisho nokuqhuma komlilo. Njengamanje, ibhethri leselula eliyisisekelo lakhiwe ngemisebenzi yokuvikela eyisisekelo njengokushajwa ngokweqile, ukugqagqana, ukujikeleza okufushane, futhi lolu hlobo lomsebenzi wokuvikela ngokuvamile lunzima, ngakho umakhalekhukhwini usetshenziswa ezimeni ezijwayelekile neziphusile.

, Umlilo noma ukuqhuma. Kodwa-ke, abakhiqizi abaningi baphishekela izikrini ezingaphezulu, izici eziningi, ukusebenza okuphezulu nokuklama kwefoni ephathekayo, ngenkathi kuthuthukiswa umthamo webhethri, ukucindezela njalo isikhala sebhethri, okubangela ukukhubazeka kokuklama kwebhethri ukuba kube yingozi ebaluleke kakhulu yokuphepha, kancane Ngokungaqondile kungabangela izingozi zokuphepha ezifana nokuqhuma kokushisa kwebhethri. Kafushane, isigubhu sebhethri siyingozi kakhulu futhi asizinzile.

Uma kungukuthuthukiswa kwalesi simo, kulula ukubangela ukuthi i-thermal yebhethri ingalawuleki, futhi ibhethri iphukile, i-electrolyte iyachichima, nomlilo onzima, ukuqhuma. Uma umsebenzisi ehlangabezana nesigubhu ebhethrini likamakhalekhukhwini, umakhalekhukhwini kufanele umiswe ngokushesha, bese uthintana nomakhalekhukhwini oshintshwayo wokulungisa umnyango ngemuva kokuthengisa. Amathiphu avimbela kanjani izigubhu zebhethri: 1, zama ukusebenzisa ishaja yasekuqaleni ukushaja, ungasebenzisi ishaja okungeyona eyangempela.

2, ungavumeli ifoni yakho iqhubeke nokuxhuma ekushajweni kweshaja. 3. Vimbela omakhalekhukhwini ezindaweni ezimbi kakhulu.

Qinisekisa ukuthi ifoni noma ibhethri yakho ishajiwe futhi isetshenziswa ngaphansi kwezinga lokushisa elifanele, ungagcini ifoni yakho ephathekayo endaweni eqondile elangeni, emotweni eshisayo, njll. 4. Uma uthola isigubhu sebhethri noma elinye iphutha, kufanele usishintshe kusenesikhathi.
