Isizathu sobunzima bokuthuthuka kwamabhethri e-lithium ion, kodwa mayelana naleli bhethri, imoto yamanje yamandla amasha, ukuguqulwa kwendawo kanye nokulungiswa kwesakhiwo se-elekthronikhi, njengobuso bobuso be-manganese dioxide, kunganciphisa ukumelana kwe-diaphragm, Ingakwazi ukucindezela ngempumelelo ukuqina kokuwohloka kwezinto ezibonakalayo kwe-lithium-rich ion ukuze kuthuthukiswe impahla, futhi ingacindezela. I-LIBOB ingathuthukisa ukuzinza okushisayo kwebhethri njengosawoti we-lithium ion kanye nezithasiselo, ukuhanjiswa kukagesi okusha. Kodwa-ke, kusekhona into ekhiqiza ukushisa, okubangela abantu ukuba banake usawoti we-lithium ion nge-LIFSI bis (i-fluorosulfonic acid) imine ions] kanye nosawoti we-boracelium ion, okwamanje, njengesibonelo sezimoto ezihlanzekile zikagesi, zithuthukise ukuminyana kwamandla jikelele kusukela kulesi sici Futhi ukuzinza, kubalulekile ukusebenzisa ibhethri le-lithium elingama-ntathu hhayi nje ukuthuthukisa umthamo walo we-lithium.

Inqwaba yokushaja okusheshayo isetshenziswa isikhathi eside, futhi ukuzinza kwebhethri ye-lithium ion kungathuthukiswa ngokwengeziwe. Ngokuhlanganisa into ekhona ye-electrode ekhona, ithuthukise ukuzinza okushisayo kwe-oksijini engaphezulu yezinto zebhethri ye-lithium-ion, impahla yebhethri ye-lithium ion ingathuthukiswa ngokuthuthukisa izimo zokuhlanganisa, futhi ingathuthukisa ukusebenza kwayo kokukhulisa, okungakheka ku-electrode engalungile. Ifilimu ye-SEI ezinzile, futhi lawa mabhethri amabili ayingxenye yebhethri ye-lithium-ion ye-lithium, yandisa izinga lokudlulisela i-lithium, lapho i-amplitude yenqubekela phambili yonyaka nayo ilinganiselwe, futhi kwenzeka into ephuma ekulawuleni okushisayo, ukuhlanganiswa kokuqina kokushisa kuhle; noma Ukusebenzisa ubuchwepheshe obuyinhlanganisela obufana namasu e-doping (njengobuchwepheshe bokunamathela) ukuze kuthuthukiswe ukuzinza okushisayo kwempahla ye-electrode enhle, isibonelo, ngaphezu kokushisa, ingozi yomlilo yamabhethri e-lithium ion incike ezintweni zebhethri.

Ukuzinza kokushisa, nakuba ukuminyana kwamandla ebhethri le-nickel kungaphezu kwebhethri le-nickel langaphambilini, futhi ukuzinza kokushisa kwempahla yebhethri kuncike ekuphenduleni kwamakhemikhali okwenzeka phakathi kwezingxenye zakhona zangaphakathi. I-lithium ion iyona efaneleka kakhulu njengamanje, kodwa le ndlela incane, izinga lokushisa lokubola lingu-302 ¡ã C, ukuzinza kokushisa kwe-lithium boric acid borate acid acid acid acid acid acid acid, ingozi yomlilo yebhethri ye-lithium ion ibalulekile kusukela ngaphakathi kwebhethri. Ukusabela kwamakhemikhali kunqunywa ukusabela kwamakhemikhali.

Amanye amamodeli asebenzisa ibhethri ye-ion ye-lithium phosphate. Kukhona futhi impahla, ukusabela kwamakhemikhali ngaphakathi kwebhethri kuyakhula. Njengamanje, abantu babalulekile ukusebenzisa i-differential scanning calorimeter (DSC).

I-Heat Analyzer (TGA), i-Adiabatic Accelerator (ARC), njll. ukutadisha ukuzinza okushisayo kwento ehlobene nebhethri, okuholela kwezinye izinto kuphela ezingakhulisa enye isigxobo futhi zithuthukise i-electrolyte, i-diaphragm,. Kuzokwenza ukushisa kukhuphuke.
