Uyini Umehluko Phakathi Kwamabhethri e-LiFePO₄ kanye ne-NCM?

Amabhethri e-lithium-ion asebalulekile ekunikezeni amandla amadivayisi esimanje, izimoto zikagesi, kanye nezinhlelo zokugcina amandla. Phakathi kwamakhemikhali amaningi e-lithium-ion atholakalayo namuhla, amabili asetshenziswa kakhulu amabhethri e-LiFePO₄ (Lithium Iron Phosphate) kanye namabhethri e-NCM (Nickel Cobalt Manganese). Uhlobo ngalunye lunezici ezihlukile, izinzuzo, kanye nezinhlelo zokusebenza ezenza zifanelekele izimo ezahlukene zokusetshenziswa.

Amabhethri e-LiFePO₄Amabhethri e-LFP, aziwa nangokuthi amabhethri e-LFP, aziwa ngokuqina kwawo okuhle kakhulu kokushisa namakhemikhali. Anesikhathi eside sokujikeleza, avame ukufinyelela imijikelezo engaphezu kuka-2000, futhi anikeza izici zokuphepha eziqinile, njengokumelana nokushisa ngokweqile kanye nengozi encane yokubaleka kokushisa noma umlilo. Ngaphezu kwalokho, asebenza kahle ngaphansi kwamazinga okushisa aphezulu futhi agcina i-voltage ezinzile ngesikhathi sokukhishwa. Kodwa-ke, ubuningi bamandla awo buphansi kunamabhethri e-NCM, okusho ukuthi agcina amandla amancane ngobukhulu noma isisindo esifanayo. Lokhu kuwenza angalungeli ukusetshenziswa lapho isikhala nesisindo kubalulekile khona.

Ngokolunye uhlangothi, Amabhethri e-NCM—yakhiwe nge-nickel, i-cobalt, kanye ne-manganese—inikeza amandla amaningi kanye namandla athile amakhulu. Lokhu kuyenza ifaneleke kakhulu ezimotweni zikagesi (ama-EV), lapho ibanga elide lokushayela kanye nosayizi webhethri elincane kubalulekile khona. Amabhethri e-NCM angaletha ukusebenza okuqinile maqondana nokusheshisa kanye nokukhishwa kwamandla aphezulu. Kodwa-ke, anempilo yomjikelezo emfushane uma kuqhathaniswa ne-LiFePO₄, ngokuvamile asukela emijikelezweni eyi-1000 kuya kweyi-1500. Ngaphezu kwalokho, ukuba khona kwe-cobalt kuphakamisa ukukhathazeka ngezemvelo kanye nokuziphatha, njengoba inqubo yayo yokumba idla izinsiza eziningi futhi ivame ukuba yimpikiswano.

Ngokuphathelene nezindleko, amabhethri e-LiFePO₄ ngokuvamile ashibhile futhi anobungani nemvelo, kuyilapho amabhethri e-NCM, naphezu kokuba ebiza kakhulu, enikeza ukusebenza okungcono maqondana nokukhishwa kwamandla. Ukukhetha phakathi kwalokhu okubili kuncike kakhulu ekusetshenzisweni: I-LiFePO₄ ikhethwa kakhulu ezindaweni zokugcina amandla ezimile kanye nezimoto zikagesi ezisheshayo, kuyilapho i-NCM ithandwa kakhulu kuma-EV asebenza kahle kanye nama-electronics aphathekayo adinga imithombo yamandla emincane, enamandla amakhulu.

Ekuphetheni, womabili amabhethri e-LiFePO₄ kanye ne-NCM anamandla nobuthakathaka bawo. Isinqumo phakathi kwawo kufanele sisekelwe ekuphepheni, izidingo zamandla, isabelomali, kanye nomthelela wemvelo.
