Ukuhlaziywa komkhuba wokuthuthukiswa kobuchwepheshe we-lithium battery electrolyte
1. I-electrolyte enamandla amakhulu
Ukuphishekela amandla athile aphezulu kuyindlela enkulu yocwaningo yebhethri ye-lithium-ion, ikakhulukazi lapho amadivaysi eselula anesisindo esiningi kakhulu empilweni yabantu, ububanzi, buba ukusebenza okubaluleke kakhulu kwebhethri.
2, I-electrolyte yamandla aphezulu
Njengamanje, ibhethri ye-lithium-ion yezentengiselwano inzima ukufeza izinga eliphezulu lokukhishwa okuqhubekayo, isizathu esibalulekile ukuthi i-battery pole indlebe ishisa kakhulu, ukumelana kwangaphakathi okuholela ekushiseni kwebhethri kuphezulu kakhulu, kuthambekele ekubalekeni okushisayo. . Ngakho-ke, i-electrolyte ingavimbela ibhethri ekushiseni ngokushesha kakhulu ngenkathi igcina i-conductivity ephezulu. Futhi mayelana namandla amabhethri e-lithium, ukufeza ukushaja okusheshayo futhi kuyisiqondiso esibalulekile sokuthuthukiswa kwe-electrolyte.
3, Ukushisa okubanzi kwe-electrolyte
Ibhethri ijwayele ukubola kwe-electrolyte ngokwayo kanye nokuqiniswa kokusabela ohlangothini phakathi kwezinto ezibonakalayo kanye nezingxenye ze-electrolyte ekushiseni okuphezulu; kuyilapho ekushiseni okuphansi kungase kube khona imvula kasawoti ye-electrolyte kanye nokuphindaphindeka kwe-impedance yefilimu ye-SEI engalungile. Okubizwa ngokuthi i-electrolyte yokushisa ebanzi ukwenza ibhethri ibe nendawo yokusebenza ebanzi.
4. Ukuphepha kwe-electrolyte
Ukuphepha kwebhethri kubalulekile ekushisweni nasekuqhumeni imbala. Okokuqala, ibhethri ngokwalo liyavutha, ngakho-ke lapho ibhethri lishajwa ngokweqile, likhishwa ngokweqile noma lifushane, lapho lithola i-pinprick yangaphandle noma i-extrusion, futhi lapho izinga lokushisa langaphandle liphezulu kakhulu, lingabangela izingozi zokuphepha. Ngakho-ke, i-flame retardant iyisiqondiso esibalulekile socwaningo lwe-electrolyte yokuphepha.
5, i-electrolyte yomjikelezo omude
Njengoba kusenezinkinga ezinkulu zobuchwepheshe ekugayweni kabusha kwamabhethri e-lithium-ion, ikakhulukazi ekugayweni kabusha kwamandla amabhethri e-lithium, ukuthuthukisa impilo yebhethri kungenye yezindlela zokudambisa lesi simo. Kunemibono emibili ebalulekile yocwaningo yohlobo lwe-electrolyte yomjikelezo omude, omunye ukuzinza kwe-electrolyte, okuhlanganisa ukuzinza okushisayo, ukuzinza kwamakhemikhali, ukuzinza kwe-voltage; okwesibili ukuzinza nezinye izinto, ezidinga ukwakheka kwefilimu okuzinzile ngama-electrode, akukho oxidation nge-diaphragm, futhi akukho ukugqwala okunoketshezi oluqoqayo.
