Amabhethri e-Lithium-ionguqula amandla amakhemikhali abe amandla kagesi ngokusebenzisa ukusabela kwamakhemikhali okuvamile.Ngokombono, ukusabela okwenzeka ngaphakathi kwebhethri ukusabela kokunciphisa i-oxidation phakathi kwama-electrode ephozithivu nenegethivu.Ngokwalokhu kusabela, i-deintercalation ye-ion ingakhiqiza yamanje, ngakho-ke i-lithium I-concentration ye-ion ngokuvamile ayishintshi.Kodwa-ke, emjikelezweni wangempela webhethri, ngaphezu kokusabela okuvamile kwe-lithium ion, ukusabela okuningi okusemaceleni kuzokwenzeka, njengokwakheka nokukhula kwefilimu ye-SEI, nokubola kwe-electrolyte.Noma yikuphi ukusabela okungakhiqiza noma ukudla ama-ion e-lithium kuzophazamisa ibhalansi yangaphakathi yebhethri.Uma ibhalansi isishintshile, izoba nomthelela omkhulu ebhethrini.Izici zangaphakathi zebhethri ezibangela ukwehla kwamandla kanye nempilo yebhethri ye-lithium-ion zimi kanje: 1. Ukushintsha kwezinto ezibonakalayo ze-electrode.2. I-electrolyte ibolile.3. Ukwakheka nokukhula kwefilimu ye-SEI.4. Ukwakhiwa kwe-lithium dendrites.5. Umthelela wezithako ezingasebenzi.
Indlela yokwehluleka kwangaphakathi kweamabhethri e-lithiumikakhulukazi kubangelwa ukwakheka kwe-lithium dendrites, izinguquko ku-cathode material kanye nokubola kwe-electrolyte.Phakathi kwazo, ukwakheka kwe-lithium dendrites kungabangela kalula izifunda ezimfushane futhi kubangele ukubaleka okushisayo kweiseli yebhethri.Dala ukuthi ibhethri liqhume.
Ekuhlaziyeni kokugcina, ucwaningo lokuhluleka kwamabhethri e-lithium ukufunda izindlela zokuhluleka kwebhethri nezindlela, ukwenza ibhethri libe ngcono, futhi kuthuthukiswe ukuphepha kwebhethri.Ngakho-ke, ucwaningo lokuhluleka kwebhethri alukwazi nje ukuba nokubaluleka kokuqondisa okubalulekile ekukhiqizeni nasekusebenzeni kwangempela, kodwa futhi lunokubaluleka okubalulekile ekuthuthukiseni ukuphila kwebhethri, ukuphepha nokwethembeka kwezimoto zikagesi, kanye nokunciphisa izindleko zezimoto zikagesi.
