Kuki bateri ya lithium idashobora gukora mubushyuhe buke?

Lisitiyumu ya kirisiti ni iki muri bateri ya lithium?

Iyo bateri ya lithium-ion irimo kwishyurwa, Li + itandukanijwe na electrode nziza kandi igahuzwa na electrode mbi; ariko mugihe ibintu bimwe bidasanzwe: nkumwanya uhagije wa lithium intercalation muri electrode mbi, kurwanya cyane Li + intercalation muri electrode mbi, Li + de-intercalates kuva electrode nziza byihuse, ariko ntishobora guhuzwa muburyo bumwe. Iyo ibintu bidasanzwe nka electrode mbi bibaye, Li + idashobora kwinjizwa muri electrode mbi irashobora kubona electron gusa hejuru ya electrode mbi, bityo igakora feza-yera ya metallic lithium, ikunze kwitwa imvura ya lithium kristu. Isesengura rya Litiyumu ntirigabanya gusa imikorere ya bateri, rigabanya cyane ubuzima bwikurikiranya, ariko kandi rigabanya ubushobozi bwumuriro bwihuse bwa bateri, kandi rishobora guteza ingaruka mbi nko gutwika no guturika. Imwe mumpamvu zingenzi ziganisha ku kugwa kwa lithium kristallisation ni ubushyuhe bwa bateri. Iyo bateri yazengurutswe n'ubushyuhe buke, reaction ya kristalisation yimvura ya lithium iba ifite umuvuduko mwinshi kuruta inzira ya lithium. Electrode mbi ikunda kugwa imvura mugihe cy'ubushyuhe buke. Litiyumu yo korohereza ibintu.

Nigute wakemura ikibazo ko bateri ya lithium idashobora gukoreshwa mubushyuhe buke

Ukeneye gushushanya ansisitemu yo kugenzura ubushyuhe bwa batiri. Iyo ubushyuhe bwibidukikije buri hasi cyane, bateri irashyuha, kandi iyo ubushyuhe bwa bateri bugeze aho bakorera, ubushyuhe burahagarara.
