Okokuqala, umthamo we-electrode ongemuhle webhethri ye-lithium ion akwanele Uma ingxenye ye-electrode engalungile yebhethri ye-lithium ion inganele, ama-athomu e-lithium lapho ukushaja kwenzeka lapho ukushaja kufakwa esakhiweni se-interlayer se-graphite ye-electrode negative, futhi ubuso be-electrode engalungile buyahlaziywa. I-crystallization ebhethri ye-lithium-ion izoholela kumjikelezo omfushane. Ngalesi sikhathi, ibhethri likhishwa ngokumangalisayo, kuzoba nenani elikhulu lokushisa, shisa i-diaphragm.

Izinga lokushisa eliphezulu lizohlaziya i-electrolyte ibe igesi, lapho ukucindezela kukhulu kakhulu, ibhethri izoqhuma. Okwesibili, umswakama uphakeme kakhulu njengebhethri ye-lithium ion, umswakama ungasabela nge-lithium, okuholela ku-lithium oxide, okuholela ekulahlekelweni kwamandla ebhethri, okulula ukubangela ukuba ibhethri likhokhiswe ngokweqile ukuze likhiqize igesi, futhi i-voltage yokuhlaziya i-hydraulic iphansi kakhulu, kulula ukuhlaziya igesi ekhiqizayo lapho ishaja, okuzokwandisa ibhethri lebhethri elingaphandle, elizokwandisa ibhethri. uma kuhlukanisiwe, ibhethri izoqhuma. Okwesithathu, i-short circuit short circuit ibangela ukukhishwa okukhulu kwamanje, kukhona ukushisa okukhulu, ukushisa i-diaphragm embi, okuholela kumjikelezo omfushane omkhudlwana, okubangela ukuthi i-electrolyte ihlaziye igesi, ingcindezi yangaphakathi inkulu kakhulu, ibhethri izoqhuma.

4. Lapho ibhethri ye-lithium-ion ishajwa ngokweqile, i-lithium yokukhululwa ngokweqile kwe-electrode enhle izoshintsha ukwakheka kwe-electrode eqondile, futhi i-lithium eyeqile ayikwazi kalula ukuyifaka ku-electrode engalungile, futhi ibangelwa kalula ukuthi ibangele i-lithium nge-negative surface, futhi lapho i-voltage Lapho ifinyelela ku-4.5V noma ngaphezulu, i-electrolyte izohlaziya inani elikhulu legesi.

Kungase kubangele ukuqhuma kuzo zonke izinhlobo. 5. I-short-circuit short circuit yangaphandle ingase ibangele iphutha elihle nelibi, ngenxa ye-short circuit yangaphandle, ukukhishwa kwebhethri okwamanje kuzokwenza ukushisa kwebhethri, izinga lokushisa eliphezulu lizokwenza ukuthi i-diaphragm ngaphakathi kwebhethri inciphe noma ilimaze ngokuphelele i-short circuit yangaphakathi.

Ngakho-ke, kwaqhuma. .
