Yonke i-Solid Polymer Electrolyte Yebhethri ye-Lithium Ion

Amandla amakhemikhali asephenduke indlela yokugcina amandla kubantu.Kusistimu yebhethri yamakhemikhali yamanje,ibhethri ye-lithiumibhekwa njengethembisa kakhuluukugcinwa kwamandlaidivayisi ngenxa yokuminyana kwamandla aphezulu, impilo yomjikelezo omude, futhi akukho mphumela wenkumbulo.Njengamanje, amabhethri e-lithium-ion endabuko asebenzisa i-organic liquid electrolyte.Nakuba ama-electrolyte anguketshezi anganikeza ukuguquguquka okuphezulu kwe-ionic kanye nokuxhumana okuhle kwesixhumi esibonakalayo, awakwazi ukusetshenziswa ngokuphepha ezinhlelweni ze-lithium zensimbi.Zinokufuduka okuphansi kwe-lithium ion futhi kulula ukuvuza.Izinkinga ezifana nokuguquguquka, ukuvutha, kanye nokuphepha okungalungile zivimbela ukuqhubeka nokuthuthuka kwamabhethri e-lithium.Uma kuqhathaniswa nama-electrolyte awuketshezi nama-electrolyte aqinile angaphili, ama-electrolyte e-polymer aqinile anezinzuzo zokusebenza kahle kokuphepha, ukuguquguquka, ukucubungula kalula kube amafilimu, kanye nokuxhumana okuhle kakhulu kwesixhumi esibonakalayo.Ngesikhathi esifanayo, bangakwazi futhi ukuvimbela inkinga ye-lithium dendrites.Njengamanje, isithole ukunakwa okukhuluOkwamanje, abantu banezidingo eziphakeme neziphakeme zamabhethri e-lithium-ion mayelana nokuphepha kanye nokuminyana kwamandla.Uma kuqhathaniswa namabhethri e-lithium-ion wesistimu ye-organic liquid yendabuko, amabhethri e-lithium e-solid-state anezinzuzo ezinkulu kulokhu.Njengenye yezinto eziyinhloko zamabhethri e-lithium e-solid-state, ama-electrolyte e-polymer e-solid-state angenye yezinkomba ezibalulekile zokuthuthukiswa kocwaningo lwebhethri ye-lithium e-solid-state.Ukuze usebenzise ngempumelelo ama-electrolyte e-polymer e-solid-state kumabhethri e-lithium ezentengiselwano, kufanele ihlangabezane nezidingo ezilandelayo: I-ion conductivity yegumbi lokushisa iseduze ne-10-4S/cm, inombolo yokufuduka kwe-lithium ion iseduze ne-1, izakhiwo ezinhle kakhulu zemishini, iwindi le-electrochemical eliseduze ne-5V, ukuzinza okuhle kwamakhemikhali ashisayo, kanye nendlela yokulungiselela enobungani nemvelo.

Kusukela kumshini wokuthuthwa kwe-ion kuwo wonke ama-polymer electrolyte aqinile, abacwaningi benze umsebenzi omningi wokuguqula, okuhlanganisa ukuhlanganisa, ukuhlanganisa i-copolymerization, ukuthuthukiswa kwama-electrolyte e-polymer conductor eyodwa-ion, ama-electrolyte e-polymer enosawoti omningi, ukwengeza ama-plasticizers, Ukwenza i-cross- ukuxhumanisa kanye nokuthuthukisa isistimu eyinhlanganisela ye-organic/inorganic.Ngalo msebenzi wokucwaninga, ukusebenza okuphelele kwe-electrolyte eqinile ye-polymer kuye kwathuthukiswa kakhulu, kodwa kubonakala sengathi i-polymer electrolyte eqinile engathengiswa esikhathini esizayo akumele itholwe ngendlela eyodwa yokuguqula, kodwa inqwaba. izindlela zokuguqula.Inhlanganisela.Kudingeka siqonde indlela yokuguqula kahle kakhulu, sikhethe indlela yokuguqula efanele yesehlakalo esingalungile, futhi sakhe i-polymer electrolyte eqinile engahlangabezana ngempela nezidingo zemakethe.
