Iyini i-lithium crystal ebhethri ye-lithium?
Uma ibhethri ye-lithium-ion ishajwa, i-Li+ iyahlukaniswa isuka ku-electrode ephozithivu futhi ixhunywe ku-electrode engemihle; kodwa lapho izimo ezithile ezingavamile: njengesikhala esinganele se-lithium intercalation ku-electrode engalungile, ukumelana kakhulu nokuhlangana kwe-Li+ ku-electrode engalungile, i-Li+ de-intercalates isuka ku-electrode ephozithivu ngokushesha kakhulu, kodwa ayikwazi ukuhlangana ngenani elifanayo. Lapho kwenzeka okungavamile okufana ne-electrode engemihle, i-Li+ engakwazi ukushumeka ku-electrode engeyinhle ingathola kuphela ama-electron ebusweni be-electrode eyinegethivu, ngaleyo ndlela yakhe into ye-metallic metallic esiliva-mhlophe, evame ukubizwa ngokuthi imvula yamakristalu e-lithium. Ukuhlaziywa kwe-lithium akunciphisi kuphela ukusebenza kwebhethri, kufinyeza kakhulu impilo yomjikelezo, kodwa futhi kukhawulela umthamo wokushaja okusheshayo webhethri, futhi kungase kubangele imiphumela eyinhlekelele njengokusha nokuqhuma. Esinye sezizathu ezibalulekile eziholela emvula ye-lithium crystallization izinga lokushisa lebhethri. Uma ibhethri lihamba ngebhayisikili ezingeni lokushisa eliphansi, ukusabela kwecrystallization kwemvula ye-lithium kunesilinganiso sokusabela esikhulu kunenqubo ye-lithium intercalation. I-electrode engeyinhle ijwayele kakhulu ukuna ngaphansi kwezimo ezisezingeni eliphansi lokushisa. I-Lithium crystallization reaction.
Indlela yokuxazulula inkinga ukuthi ibhethri ye-lithium ayikwazi ukusetshenziswa ekushiseni okuphansi
Kudingeka ukuklama iuhlelo lokulawula izinga lokushisa kwebhethri oluhlakaniphile. Uma izinga lokushisa le-ambient liphansi kakhulu, ibhethri liyashisisa, futhi lapho izinga lokushisa lebhethri lifinyelela ebangeni lokusebenza kwebhethri, ukushisisa kuyamiswa.
