Mu myaka yashize, amakuru y’umuriro ndetse n’ibisasu byatewe na bateri ya lithium-ion arasanzwe.Bateri ya Litiyumu-ion igizwe ahanini nibikoresho bibi bya electrode, electrolyte nibikoresho byiza bya electrode.Igikorwa cyimiti ya electrode yibikoresho ya grafite muburyo bwashizwemo ni nka lithium yicyuma.Filime ya SEI hejuru yabora kubushyuhe bwinshi, kandi ioni ya lithium yashyizwe muri grafite yakira hamwe na electrolyte hamwe na fluor ya binder polyvinylidene hanyuma amaherezo ikarekura ubushyuhe bwinshi.

Alkyl karubone ibisubizo kama ikoreshwa mubisanzwe nka electrolytite, yaka.Ibikoresho byiza bya electrode mubisanzwe ni inzibacyuho ya oxyde yinzibacyuho, ifite imbaraga za okiside ikomeye muburyo bwashizwemo, kandi ikabora byoroshye kurekura ogisijeni mubushyuhe bwinshi.Umwuka wa ogisijeni urekuwe ukorana na electrolyte kugirango oxyde, hanyuma isohoka ubushyuhe bwinshi.

Mubisanzwe, bateri ya lithium ion yaba idahindagurika mugihe ushyushye hamwe nubushyuhe bwinshi.None, mubyukuri bizagenda bite turamutse dukomeje gushyushya bateri?Hano twakoze ikizamini nyacyo kuri selile yuzuye ya NCM ifite voltage ya 3.7 V nubushobozi bwa 106 Ah.

Uburyo bwo Kwipimisha：

1. Ku bushyuhe bwicyumba (25 ± 2 ℃), selile imwe isohoka bwa mbere kuri voltage yo hasi ntarengwa hamwe numuyoboro wa 1C hanyuma igasigara muminota 15.Noneho koresha 1C ihoraho kugirango yishyure hejuru yumubyigano wo hejuru hanyuma uhindure amashanyarazi ahoraho, uhagarike kwishyuza mugihe amashanyarazi yagabanutse kugeza 0.05C, hanyuma ubishyire kuruhande muminota 15 nyuma yo kwishyuza;

2. Ongera ubushyuhe kuva ubushyuhe bwicyumba kugera kuri 200 ° C kuri 5 ° C / min, kandi ugumane kuri 5 ° C kuri litiro muminota 30;

Umwanzuro:

Litiyumu selile amaherezo izafata umuriro mugihe ubushyuhe bwikizamini bwiyongereye.Duhereye kubikorwa byavuzwe haruguru tubanza kubona valve yuzuye yafunguwe, amazi yasohotse;uko ubushyuhe buzamuka cyane, isohoka rya kabiri ryamazi ryabaye hanyuma ritangira gutwikwa.Utugingo ngengabuzima twa batiri twananiwe hafi ya 138 ° C, wari usanzwe uri hejuru y’ubushyuhe busanzwe bwa 130 ° C.
