Ukuhlolwa kokuguga nokutholwa kokuguga kweamabhethri e-lithium-ionezokuhlola impilo yebhethri kanye nokuwohloka kokusebenza. Lokhu kuhlolwa nokutholwa kungasiza ososayensi nonjiniyela baqonde kangcono izinguquko kumabhethri ngesikhathi sokusetshenziswa futhi banqume ukwethembeka nokuzinza kwamabhethri.
Nazi ezinye zezizathu eziyinhloko:
1. Hlola impilo: Ngokulingisa ukushaja komjikelezo kanye nenqubo yokukhipha ibhethri ngaphansi kwezimo zokusebenza ezihlukene, impilo nempilo yesevisi yebhethri ingachazwa. Ngokwenza izivivinyo zokuguga zesikhathi eside, impilo yebhethri ekusetshenzisweni kwangempela ingalingiswa, futhi ukusebenza nokuphelelwa amandla kwebhethri kungatholwa kusenesikhathi.
2. Ukuhlaziywa kokuwohloka kokusebenza: Ukuhlolwa kokuguga kungasiza ekunqumeni ukuwohloka kokusebenza kwebhethri ngesikhathi sokushajwa komjikelezo nenqubo yokukhipha, njengokuncipha komthamo, ukukhuphuka kokungazweli kwangaphakathi, njll. Lokhu kuncishiswa kuzothinta ukushajwa kwebhethri nokusebenza kahle kokukhipha kanye nomthamo wokugcina amandla. .
3. Ukuhlola ukuphepha: Ukuhlolwa kokuguga kanye nokutholwa kokuguga kusiza ukuthola izingozi zokuphepha ezingaba khona kanye nokungasebenzi kahle okungenzeka phakathi nokusetshenziswa kwebhethri. Isibonelo, ukuhlolwa kokuguga kungasiza ukuthola ukusebenza kokuphepha ngaphansi kwezimo ezifana nokushajwa ngokweqile, ukukhipha ngokweqile, nezinga lokushisa eliphezulu, futhi kuthuthukiswe ukwakheka kwebhethri namasistimu okuvikela.
4. Idizayini ethuthukisiwe: Ngokwenza izivivinyo zokuguga nokutholwa kokuguga kumabhethri, ososayensi nonjiniyela bangasiza ososayensi nonjiniyela baqonde izici futhi bashintshe amaphethini amabhethri, ngaleyo ndlela bathuthukise inqubo yokuklama nokukhiqiza kwamabhethri futhi bathuthukise ukusebenza kwebhethri nempilo yokuphila.
Kafushane, ukuhlola ukuguga nokutholwa kokuguga kubaluleke kakhulu ukuqonda nokuhlola ukusebenza nempilo yamabhethri e-lithium-ion, okungasisiza sidizayine kangcono futhi sisebenzise amabhethri futhi sikhuthaze ukuthuthukiswa kobuchwepheshe obuhlobene.
Yiziphi izinqubo zokuhlola ukuguga kwebhethri le-lithium nokuhlolwa kwephrojekthi?
Ngokuhlolwa nokuqapha okuqhubekayo kwalokhu kusebenza okulandelayo, singaqonda kangcono izinguquko kanye nokuncishiswa kwebhethri ngesikhathi sokusetshenziswa, kanye nokwethembeka, ubude besikhathi nezici zokusebenza kwebhethri ngaphansi kwezimo ezithile zokusebenza.
1. Ukufiphala kwamandla: Ukufiphala kwamandla kungenye yezinkomba eziyinhloko zokwehla kwempilo yebhethri. Ukuhlolwa kokuguga kuzokwenza ngezikhathi ezithile ukushaja nokukhipha imijikelezo ukuze kulingise ukushajwa komjikelezo kanye nenqubo yokukhipha ibhethri ekusetshenzisweni kwangempela. Linganisa ukuwohloka komthamo webhethri ngokulinganisa ushintsho kumthamo webhethri ngemva komjikelezo ngamunye.
2. Impilo yomjikelezo: Impilo yomjikelezo isho ukuthi mingaki imijikelezo yokushaja ephelele neyokukhipha ibhethri elingadlula kuyo. Ukuhlolwa kokuguga kwenza inombolo enkulu yokushaja nokukhipha imijikelezo ukuze kuhlolwe impilo yomjikelezo webhethri. Ngokuvamile, ibhethri libhekwa njengelifinyelele esiphethweni sempilo yalo yomjikelezo lapho amandla alo ebola afinyelele kumaphesenti athile omthamo walo wokuqala (isb., 80%).
3. Ukwenyuka kokumelana kwangaphakathi: Ukumelana kwangaphakathi kuyinkomba ebalulekile yebhethri, ethinta ngokuqondile ukushajwa kwebhethri nokusebenza kahle kokukhipha kanye nokusebenza kahle kokuguqulwa kwamandla. Ukuhlolwa kokuguga kuhlola ukwanda kokumelana nebhethri kwangaphakathi ngokulinganisa ushintsho ekuqineni kwangaphakathi kwebhethri ngesikhathi sokushajwa nokukhipha.
4. Ukusebenza kokuphepha: Ukuhlolwa kokuguga futhi kufaka phakathi ukuhlolwa kokusebenza kokuphepha kwebhethri. Lokhu kungase kuhlanganise ukulingisa ukusabela nokuziphatha kwebhethri ngaphansi kwezimo ezingavamile njengezinga lokushisa eliphezulu, ukushajwa ngokweqile, nokukhipha ngokweqile ukuze kutholwe ukuphepha nokuzinza kwebhethri ngaphansi kwalezi zimo.
5. Izici zezinga lokushisa: Izinga lokushisa linomthelela obalulekile ekusebenzeni kwebhethri nempilo. Ukuhlolwa kokuguga kungalingisa ukusebenza kwamabhethri ngaphansi kwezimo ezihlukene zokushisa ukuze kuhlolwe impendulo nokusebenza kwebhethri ekushintsheni kwezinga lokushisa.
Kungani ukumelana kwangaphakathi kwebhethri kukhula ngemva kokusetshenziswa isikhathi esithile? Uyoba yini umthelela?
Ngemuva kokuthi ibhethri lisetshenziswe isikhathi eside, ukumelana kwangaphakathi kuyanda ngenxa yokuguga kwezinto zebhethri kanye nesakhiwo. Ukumelana kwangaphakathi ukumelana okuhlangabezana nakho lapho ibhethri ligeleza. Kunqunywa izici eziyinkimbinkimbi zendlela ye-conductive yangaphakathi yebhethri eyakhiwe ama-electrolyte, izinto ze-electrode, abaqoqi bamanje, ama-electrolyte, njll. Okulandelayo umthelela wokwanda kokumelana kwangaphakathi ekusebenzeni kahle kokukhipha:
1. Ukwehla kwamandla kagesi: Ukumelana nangaphakathi kuzobangela ibhethri ukuthi ikhiqize ukwehla kwamandla kagesi ngesikhathi sokuyikhipha. Lokhu kusho ukuthi i-voltage yangempela yokuphumayo izoba ngaphansi kunevoltheji yesekethe evulekile yebhethri, ngaleyo ndlela yehlise amandla atholakalayo ebhethri.
2. Ukulahlekelwa amandla: Ukumelana kwangaphakathi kuzobangela ibhethri ukuthi ikhiqize ukushisa okwengeziwe phakathi nokukhipha, futhi lokhu kushisa kumelela ukulahlekelwa kwamandla. Ukulahlekelwa amandla kunciphisa ukusebenza kahle kokuguqulwa kwamandla ebhethri, okwenza ibhethri linikeze amandla angasebenzi kahle ngaphansi kwezimo ezifanayo zokukhipha.
3. Ukukhishwa kwamandla okuncishisiwe: Ngenxa yokwanda kokumelana kwangaphakathi, ibhethri lizoba nokwehla okukhulu kwamandla kagesi kanye nokulahlekelwa amandla lapho ikhipha amandla amanje aphezulu, okuzokwenza ibhethri lingakwazi ukuhlinzeka ngokukhipha amandla aphezulu. Ngakho-ke, ukusebenza kahle kokukhipha kuyancipha futhi namandla okukhipha amandla ebhethri ayancipha.
Ngamafuphi, ukukhushulwa kokungazweli kwangaphakathi kuzobangela ukuthi ibhethri likhiphe ukusebenza kahle, lokho kuthinte amandla atholakalayo ebhethri, ukuphuma kwamandla, nokusebenza kukonke. Ngakho-ke, ukunciphisa ukumelana kwangaphakathi kwebhethri kungathuthukisa ukusebenza kahle nokukhipha kwebhethri kwebhethri.
