Rahoton Tesla na 2021 Q3 ya sanar da canzawa zuwa baturan LiFePO4 a matsayin sabon ma'auni a cikin motocin sa.Amma menene ainihin batirin LiFePO4?
NEW YORK, NEW YORK, Amurka, Mayu 26, 2022 /EINPresswire.com/ - Shin su ne mafi kyawun madadin batir Li-Ion?Ta yaya waɗannan batura suka bambanta da sauran batura?

Gabatarwa ga Batura LiFePO4
Baturin lithium iron phosphate (LFP) baturi ne na lithium-ion mai saurin caji da adadin caji.Baturi ne mai caji tare da LiFePO4 azaman cathode da lantarki mai hoto mai hoto tare da goyan bayan ƙarfe azaman anode.

Batura LiFePO4 suna da ƙarancin ƙarfin kuzari fiye da batirin lithium-ion da ƙananan ƙarfin aiki.Suna da ƙarancin fitarwa tare da lanƙwasa lebur kuma sun fi Li-ion aminci.Waɗannan batura kuma ana kiran su da batir lithium ferrophosphate.
