Makullin tsawon rai naLFP baturi wutar lantarki ce ta aiki, wacce ke tsakanin 3.2 da 3.65 volts, kasa da karfin wutar lantarki da batirin NCM ke amfani da shi.Batirin phosphate na lithium baƙin ƙarfe yana amfani da phosphate a matsayin ingantaccen abu da kuma carbon graphite electrode a matsayin mummunan lantarki;Hakanan suna da tsawon rayuwar sabis, kyakkyawan kwanciyar hankali na thermal da kyakkyawan aikin injin lantarki.
LFP baturiyana aiki da ƙarfin lantarki na 3.2V, don haka lokacin da aka haɗa batura huɗu, ana iya samun baturin 12.8V;Ana iya samun baturin 25.6V lokacin da aka haɗa batura 8.Saboda haka, sunadarai na LFP shine mafi kyawun zaɓi don maye gurbin baturan gubar-acid mai zurfi a cikin aikace-aikace daban-daban.Ya zuwa yanzu, karancin makamashin da suke da shi ne ya takaita amfani da su a manyan motoci, domin sun fi arha da aminci.Wannan yanayin ya haifar da karbuwar wannan fasaha a kasuwannin kasar Sin, dalilin da ya sa ake kera kashi 95% na batir phosphate na lithium a kasar Sin.
Batirin mai graphite anode da LFP cathode yana aiki a matsakaicin ƙarfin lantarki na 3.2 volts da matsakaicin ƙarfin lantarki na 3.65 volts.Tare da waɗannan ƙarfin lantarki (kuma suna da ƙasa sosai), za'a iya cimma zagayowar rayuwa 12000.Duk da haka, batura masu graphite anode da NCM (nickel, cobalt da manganese oxide) ko NCA (nickel, nickel da aluminum oxide) cathode na iya aiki a mafi girman ƙarfin lantarki, tare da ƙananan ƙarfin lantarki na 3.7 volts da matsakaicin matsakaicin 4.2 volts.A karkashin waɗannan sharuɗɗan, ba a sa ran cimma fiye da 4000 na caji da zagayawa.
Idan ƙarfin ƙarfin aiki ya yi ƙasa, ruwan electrolyte tsakanin na'urorin baturi guda biyu (ta hanyar da lithium ions ke motsawa) ya fi ƙarfin sinadarai.Wannan bangare ya bayyana dalilin da ya sa baturin LTO da ke aiki a 2.3V da baturin LFP da ke aiki a 3.2V sun fi rayuwa mafi kyau fiye da batirin NCM ko NCA da ke aiki a 3.7V.Lokacin da baturin yana da ƙarin caji kuma saboda haka ƙarfin lantarki mafi girma, ruwan lantarki zai fara lalata wutar lantarki a hankali.Saboda haka, babu baturi mai amfani da spinel a halin yanzu.Spinel ma'adinai ne da manganese da aluminum suka yi.Wutar lantarki ta cathode shine 5V, amma ana buƙatar sabon electrolyte da ingantaccen murfin lantarki don hana lalata.
Wannan shine dalilin da ya sa ya zama dole a ajiye baturi a mafi ƙarancin yiwuwar SoC (yanayin caji ko% caji), saboda zai yi aiki a ƙananan ƙarfin lantarki kuma za a tsawaita rayuwarsa.
