Ungakhokhisi ngezinga lokushisa eliphansi

Ebusika, abasebenzisi bezimoto zikagesi banemizwa esobala yokuthi impilo yebhethri imfushane! Kungani lokhu?

Ngamabhethri e-lithium, ayikho inkolelo-mbono ecacile yokusekela ukumelana kwangaphakathi, isiteji sokukhipha, impilo kanye nomthamo wamabhethri e-lithium emazingeni okushisa ahlukene. Amafomula okubala ahlobene namamodeli ezibalo asesesigabeni sokuhlola. Ngokuvamile, amabhethri e-lithium awazwani namazinga okushisa ebangeni lika-0-40 ° C, kodwa ngale kwalolu hlu, ukuphila kwawo namandla azokwehla.

Njengoba ukuhamba okuphezulu nokuvumelana kwamabhethri e-lithium nakho kuyinkinga enkulu, okuqukethwe okuthile akukwazi ukunqunywa. Ngisho neqoqo elifanayo lemikhiqizo, idatha efanayo, nenqubo efanayo inemisebenzi ehluke kakhulu.

Ngemuva kokuhlolwa okuningi, ukusebenza kwezinga lokushisa eliphansi lamabhethri e-lithium ngaphansi kwedatha ehlukene nakho kuhlukile. Manje i-lithium iron phosphate eshisa kakhulu inomsebenzi wokushisa ophansi ophansi kakhulu. Amandla okukhishwa kwemikhiqizo yethu ku–10°C angama-89% womthamo omkhulu wokukhululwa, okufanele ube phezulu uma kuqhathaniswa embonini. Ku-55 ° C, umthamo wokukhipha ungafinyelela ku-95%, futhi ukuncishiswa kusekuncane kakhulu emazingeni okushisa aphansi. Lona kusewumkhiqizo ozohlolwa. Uyazi, ikhwalithi yayo iphakeme kakhulu kunemikhiqizo evamile emgqeni womhlangano.

Ngokuphambene, i-lithium manganese, i-lithium cobalt kanye nemikhiqizo ye-ternary inemisebenzi engcono yokushisa ephansi, kodwa futhi inemikhawulo. Umhlatshelo wukusebenza kwezinga lokushisa eliphezulu. Njengamanje, umsebenzi wokuphepha we-lithium iron phosphate ovuthwe yizimboni uphakeme kakhulu, futhi umsebenzi wokushisa ophakeme nawo muhle uma kuqhathaniswa. Eqinisweni, ukusebenza kwebhethri akuphakeme njengezinhlobo ezintathu ezingenhla, futhi kuphephile uma kuqhathaniswa. Umsebenzi usuwonke awukabi muhle njenge-manganese, i-lithium noma i-ternary.

Ngakho-ke, abanye abantu bakhononda ngokuthi amabhethri e-lithium awakwazi ukushajwa ebusika. Ingxenye yesizathu sokuthi basebenzise ukuphathwa kwebhethri ukuthi umkhiqizo uvikelekile. Impilo yesevisi yamabhethri e-lithium ebusika nakanjani izoba mfushane kunasehlobo. Lapha ukukhumbuza wonke umuntu ukuthi kungcono ukungakhokhisi amabhethri e-lithium ebusika. Ngenxa yokushisa okuphansi, ama-ion e-lithium azocwebezela ku-electrode engalungile, adlule ngqo esikhaleni, futhi ngokuvamile enze isifunda esincane esifushane, esithinta impilo yenkonzo nomsebenzi, futhi angase aqhume ezimweni ezimbi kakhulu!
