Kayan lantarki mara kyau don batirin lithium{0}ion:

Batirin lithium mai ƙarfi: Mai dacewa da baturan lithium na ternary (NCM) da batir phosphate na lithium iron phosphate (LFP), waɗanda ake amfani da su don sabbin motocin makamashi (kamar fakitin baturi mai ƙarfi) da manyan motoci masu nauyi na lantarki-. Baturin zai iya riƙe ƙarfin riƙewa sama da ko daidai da 80% bayan zagayowar 1500, kuma ƙarfin zai iya kaiwa 80% cikin mintuna 30 na caji cikin sauri.

Batir lithium masu amfani: Ana amfani da su don wayoyi da kwamfyutoci don haɓaka ƙarfin ƙarfin baturi (Mafi girma ko daidai da 700Wh/L) da tsawaita rayuwar baturi guda ɗaya.

Batirin lithium ajiyar makamashi: Ana amfani da shi a cikin tashoshin wutar lantarki na gida da tsarin ajiyar makamashi na tushe, tare da ƙimar riƙe ƙarfin fitarwa sama da ko daidai da 75% a cikin ƙananan yanayin zafi na -20 digiri.
