Kungakanani ukujula kokukhishwa kwamabhethri e-Li-ion polymer?
Kusukela kanjaloamabhethri e-lithium-ionkukhokhiswa kufanele kukhishwe, kusukela endaweni yokubuka ye-macroscopic, inqubo yokukhipha ukuphepha kwebhethri ye-lithium-ion ilinganiselwe, ukukhishwa kufanele kunake izinga lokukhipha kanye nokujula kokukhishwa, ukujula kokukhishwa yinani lenani lokukhishwa. kanye namandla okuzisholo, kunevelu ku-voltage yethagethi yereferensi engcono kakhulu. Ukujula kwebhethri ye-lithium-ion yokukhipha isilinganiso senani elikhishiwe kanye nesamba samandla agciniwe (umthamo omncane) webhethri le-lithium-ion. Uma isibalo siphansi, kusho ukukhishwa okungajulile. Ukujula kwebhethri ye-lithium-ion yokukhishwa kuhlobene eduze ne-voltage kanye ne-current, futhi kungashiwo ukuthi ivezwa ngokuyinhloko ku-voltage futhi isebenza ekusebenzeni kwamanje.
Ukujula kokukhishwa kwamabhethri e-lithium-ion kungu-80%, okusho ukuthi akhishwa ku-20% osele womthamo. Umthelela wokujula kokukhipha ebhethrini: lapho kujula ukujula kokukhishwa, kulula ukufinyeza impilo yamabhethri e-lithium-ion; esinye isici ukusebenza ku-curve yokukhipha, ukujula kokukhishwa kuhamba, i-voltage engazinzile namanje. Embusweni ofanayo wokukhipha, inani eliphansi le-voltage, libonisa ukuthi ukujula kokujula kokukhishwa. Ukukhishwa kwamanje okuncane kuphelele kakhulu, kuya phansi ukusebenza kwamanje, isikhathi eside sokusebenza esiphephile, siyancipha inani lenkokhelo elifika ku-voltage efanayo. Ngamafuphi, phawula nganoma yisiphi isihloko sokukhishwa kwebhethri ye-lithium-ion ukuze ucabangele umbuso wokukhipha, ukhiye umanje osebenzayo.
Ibhethri ye-lithium-ion kunoma isiphi isisetshenziswa sikagesi ngokwenani lokunikezwa kwamandla asebenzayo, inani langaphakathi lokumelana lebhethri nalo lizolandela umthamo wokwehla nokwenyuka, ukuthi lapho ukujula kokukhipha kukhulu, inani lokumelana liyakhula ngenkathi ukusebenza kwamanje akushintshi, ibhethri liyadingeka ukuze linikeze amandla amaningi futhi limosheke ngendlela yokushisa.
Ibhethri ye-lithium-ionekuqaleni ijika lokukhipha elibushelelezi ekujuleni kokukhishwa kuzoshintsha kakhulu, ngakho-ke ukujula kokukhishwa kukhawulelwe ebangeni eliyisicaba, ukuze amakhasimende akwazi ukulawula kangcono amandla, kodwa futhi athole ulwazi olungcono lokusebenzisa. .
Isifinyezo sokujula kokukhishwa kwebhethri le-Polymer Li-ion:
Ukujula kokujula kokukhishwa kwamabhethri e-lithium-ion, ukulahleka okukhulu kwamabhethri; amabhethri e-lithium-ion ashajwe ngokugcwele, ukulahleka okukhulu kwamabhethri nakho kuzoba kukhulu. Inketho engcono kakhulu yamabhethri e-lithium-ion phakathi nendawo yamandla, ukuze impilo yebhethri ibe yinde kakhulu.
