Nigute ingufu za bateri zigira ingaruka kumwanya wo kwishyuza?

Ubucucike bw'ingufu bugira ingaruka ku buryo butaziguye umuvuduko wo kwishyuza. Batteri yubucucike isaba selile nkeya kubushobozi bungana, kugabanya igiteranyo gikenewe kubiciro byatanzwe. Gupakira, electrode yuzuye irashobora kubuza lithium - ion kugenda, bigatera impagarara zubushakashatsi hagati yumuriro wihuse nubucucike bwinshi. Ababikora baringaniza ibyo bintu binyuze mubyuma bya electrode hamwe no gucunga neza ubushyuhe.

Kuki bateri zitageze ku bucucike bwa lisansi?

Imiti ya hydrocarbone ibika ingufu nyinshi kuri massage kuruta reaction ya electrochemic reaction muri batteri. Benzin ikomatanya karubone na hydrogène kuri 12,000 Wh / kg na lithium - ion ya theoretical ntarengwa ya 1,250 Wh / kg. Itandukaniro rituruka kuri chimie yibanze: reaction yo gutwika irekura ingufu ziva muri CO₂ na H₂O, mugihe bateri zibika ingufu binyuze muri atome - igipimo cya ion. Tekinoroji ya bateri ikomeje gutera imbere ariko ntishobora gutsinda uku kuri kwimiti.

Ni irihe tandukaniro riri hagati ya Wh / kg na Wh / L?

Wh / kg (gravimetric energy density) ipima ingufu muburemere bwa - ingenzi mu bwikorezi aho uburemere bugira ingaruka kumikorere no mumikorere. Wh / L (ubwinshi bwingufu zingana) ipima ingufu mubunini bwa - ingenzi kumwanya - porogaramu zabujijwe nka terefone zigendanwa no gupakira ibinyabiziga bitwara abagenzi. Ibisobanuro byombi bifite akamaro, ariko porogaramu zitandukanye zishyira imbere imwe kurindi.
