Ukuhlolwa kokuguga kanye nokutholwa kokugugaamabhethri e-lithium-ionukuhlola impilo yebhethri kanye nokuwohloka kokusebenza. Lokhu kuhlola nokuthola kungasiza ososayensi nonjiniyela ukuqonda kangcono izinguquko kumabhethri ngesikhathi sokusetshenziswa nokunquma ukuthembeka nokuzinza kwamabhethri.
Nazi ezinye zezizathu eziyinhloko:
1. Hlola impilo: Ngokulingisa inqubo yokushaja nokukhipha ibhethri ngaphansi kwezimo zokusebenza ezahlukene, impilo kanye nokuphila kwesevisi yebhethri kungaqagelwa. Ngokwenza izivivinyo zokuguga zesikhathi eside, impilo yebhethri esetshenziswayo ingalingiswa, futhi ukusebenza kanye nokuphela kwamandla ebhethri kungatholakala kusenesikhathi.
2. Ukuhlaziywa kokuwohloka kokusebenza: Ukuhlolwa kokuguga kungasiza ekunqumeni ukuwohloka kokusebenza kwebhethri ngesikhathi senqubo yokushaja nokukhipha umjikelezo, njengokuncipha kwamandla, ukwanda kokumelana kwangaphakathi, njll. Lokhu kuncipha kuzothinta ukusebenza kahle kokushaja nokukhipha kwebhethri kanye nomthamo wokugcina amandla.
3. Ukuhlolwa kokuphepha: Ukuhlolwa kokuguga kanye nokutholwa kokuguga kusiza ekutholeni izingozi zokuphepha ezingaba khona kanye nokungasebenzi kahle okungase kwenzeke ngesikhathi sokusetshenziswa kwebhethri. Isibonelo, ukuhlolwa kokuguga kungasiza ekutholeni ukusebenza kokuphepha ngaphansi kwezimo ezifana nokushaja ngokweqile, ukukhipha ngokweqile, kanye nokushisa okuphezulu, futhi kuthuthukise kakhulu ukwakheka kwebhethri kanye nezinhlelo zokuvikela.
4. Umklamo olungiselelwe: Ngokwenza izivivinyo zokuguga kanye nokuthola ukuguga kumabhethri, ososayensi nonjiniyela bangasiza ososayensi nonjiniyela ukuqonda izici nokushintsha amaphethini amabhethri, ngaleyo ndlela kuthuthukiswe inqubo yokuklama nokukhiqiza amabhethri kanye nokuthuthukisa ukusebenza kwebhethri kanye nesikhathi sokuphila.
Ngamafuphi, ukuhlolwa kokuguga kanye nokutholwa kokuguga kubaluleke kakhulu ukuqonda nokuhlola ukusebenza kanye nokuphila kwamabhethri e-lithium-ion, okungasisiza ukuklama nokusebenzisa amabhethri kangcono nokukhuthaza ukuthuthukiswa kobuchwepheshe obuhlobene.
Yiziphi izinqubo zokuhlola ukuguga kwebhethri le-lithium kanye nokuhlolwa kwephrojekthi?
Ngokuhlola nokuqapha okuqhubekayo kokusebenza okulandelayo, singaziqonda kangcono izinguquko kanye nokuncipha kwebhethri ngesikhathi sokusetshenziswa, kanye nokuthembeka, isikhathi sokuphila kanye nezici zokusebenza kwebhethri ngaphansi kwezimo ezithile zokusebenza.
1. Ukuncipha kwamandla: Ukuncipha kwamandla kungenye yezinkomba eziyinhloko zokwehla kokuphila kwebhethri. Ukuhlolwa kokuguga kuzokwenza imijikelezo yokushaja nokukhipha ngezikhathi ezithile ukuze kulingise inqubo yokushaja nokukhipha ibhethri elisetshenziswa ngempela. Hlola ukwehla kwamandla ebhethri ngokulinganisa ushintsho kumthamo webhethri ngemva komjikelezo ngamunye.
2. Impilo yomjikelezo: Impilo yomjikelezo ibhekisela ekutheni ibhethri lingadlula emijikelezweni eminingi yokushaja nokukhipha ephelele. Ukuhlolwa kokuguga kwenza inani elikhulu lemijikelezo yokushaja nokukhipha ukuze kuhlolwe impilo yomjikelezo webhethri. Ngokuvamile, ibhethri kubhekwa ukuthi selifinyelele ekupheleni kwempilo yalo yomjikelezo lapho amandla alo ewohloka abe yiphesenti elithile lomthamo walo wokuqala (isb., 80%).
3. Ukwanda kokumelana kwangaphakathi: Ukumelana kwangaphakathi kuyinkomba ebalulekile yebhethri, ethinta ngqo ukusebenza kahle kokushaja nokukhipha kwebhethri kanye nokusebenza kahle kokuguqulwa kwamandla. Ukuhlolwa kokuguga kuhlola ukwanda kokumelana kwangaphakathi kwebhethri ngokulinganisa ushintsho ekumelaneni kwangaphakathi kwebhethri ngesikhathi sokushaja nokukhipha.
4. Ukusebenza kokuphepha: Ukuhlolwa kokuguga kuhlanganisa nokuhlolwa kokusebenza kokuphepha kwebhethri. Lokhu kungafaka phakathi ukulingisa ukusabela nokuziphatha kwebhethri ngaphansi kwezimo ezingavamile njengokushisa okuphezulu, ukushaja ngokweqile, kanye nokukhipha ngokweqile ukuze kutholakale ukuphepha nokuzinza kwebhethri ngaphansi kwalezi zimo.
5. Izici Zokushisa: Izinga lokushisa linomthelela obalulekile ekusebenzeni kwebhethri kanye nokuphila kwayo. Ukuhlolwa kokuguga kungalingisa ukusebenza kwamabhethri ngaphansi kwezimo zokushisa ezahlukene ukuhlola impendulo yebhethri kanye nokusebenza kwayo ezinguqukweni zokushisa.
Kungani ukumelana kwangaphakathi kwebhethri kukhula ngemva kokusetshenziswa isikhathi esithile? Kuzoba yini umthelela?
Ngemva kokusetshenziswa kwebhethri isikhathi eside, ukumelana kwangaphakathi kuyanda ngenxa yokuguga kwezinto zebhethri kanye nesakhiwo salo. Ukumelana kwangaphakathi ukumelana okuhlangatshezwana nakho lapho ugesi ugeleza ebhethrini. Kunqunywa izici eziyinkimbinkimbi zendlela yangaphakathi yokuqhuba yebhethri eyakhiwe ngama-electrolyte, izinto ze-electrode, abaqoqi bamanje, ama-electrolyte, njll. Okulandelayo umthelela wokumelana kwangaphakathi okwandisiwe ekusebenzeni kahle kokukhipha:
1. Ukwehla kwamandla kagesi: Ukumelana kwangaphakathi kuzokwenza ibhethri likhiqize ukwehla kwamandla kagesi ngesikhathi senqubo yokukhipha. Lokhu kusho ukuthi amandla kagesi okukhiphayo azoba ngaphansi kwamandla kagesi avulekile ebhethri, ngaleyo ndlela kuncishiswe amandla atholakalayo ebhethri.
2. Ukulahlekelwa amandla: Ukumelana kwangaphakathi kuzokwenza ibhethri likhiqize ukushisa okwengeziwe ngesikhathi sokukhishwa, futhi lokhu kushisa kumelela ukulahlekelwa amandla. Ukulahlekelwa amandla kunciphisa ukusebenza kahle kokuguqulwa kwamandla kwebhethri, okubangela ukuthi ibhethri linikeze amandla angasebenzi kahle ngaphansi kwezimo ezifanayo zokukhishwa.
3. Ukwehla kwamandla okukhipha: Ngenxa yokwanda kokumelana kwangaphakathi, ibhethri lizoba nokwehla okukhulu kwamandla okukhipha kanye nokulahlekelwa amandla uma likhipha amandla aphezulu, okuzokwenza ibhethri lingakwazi ukunikeza amandla aphezulu ngempumelelo. Ngakho-ke, ukusebenza kahle kokukhipha amandla kuyancipha futhi amandla okukhipha amandla ebhethri ayancipha.
Ngamafuphi, ukumelana kwangaphakathi okwandisiwe kuzokwenza ukuthi ukusebenza kahle kokukhipha ibhethri kwehle, ngaleyo ndlela kuthinte amandla atholakalayo ebhethri, ukukhishwa kwamandla, kanye nokusebenza kwayo yonke indawo. Ngakho-ke, ukunciphisa ukumelana kwangaphakathi kwebhethri kungathuthukisa ukusebenza kahle kokukhipha ibhethri.
