如何储存聚合物软包锂电池?

2022-04-20

聚合物软包锂电池

关(guan)于(yu)聚合物(wu)软包锂电池储存,你(ni)需要知道的件事是,不(bu)能(neng)给(ji)电池充(chong)满电,这(zhei)是为什么呢?

因为聚合物软(ruan)包(bao)锂电(dian)池(chi)会(hui)发生化学(xue)反应,长时(shi)间充满(man)电(dian)会(hui)增强化学(xue)反应而降解电(dian)池(chi),当电(dian)池(chi)膨胀或重复使用时(shi),导致低效率(lv)降低。另一方面,在3V以下放(fang)电(dian)也会(hui)损(sun)坏(huai)电(dian)池(chi)。将(jiang)聚合物软(ruan)包(bao)锂电(dian)池(chi)存储在低于3.5V的(de)电(dian)压(ya)下会(hui)增加电(dian)池(chi)故障的(de)可能性和寿命预(yu)期(qi)。

聚合(he)物软包锂电(dian)(dian)(dian)池(chi)(chi)理想的存储(chu)(chu)电(dian)(dian)(dian)压范围是(shi)3.7V,这大(da)约是(shi)50%的电(dian)(dian)(dian)量(liang),40%到(dao)60%的电(dian)(dian)(dian)量(liang)都(dou)可(ke)以。将电(dian)(dian)(dian)池(chi)(chi)插(cha)入平衡充(chong)电(dian)(dian)(dian)器或使(shi)用(yong)万用(yong)表并放电(dian)(dian)(dian)存储(chu)(chu)。如(ru)果充(chong)电(dian)(dian)(dian)器没有(you)自动功能,简单地给电(dian)(dian)(dian)池(chi)(chi)放电(dian)(dian)(dian),使(shi)电(dian)(dian)(dian)池(chi)(chi)电(dian)(dian)(dian)压降到(dao)接近(jin)3.7V。

那么(me)聚合(he)物软包(bao)锂电(dian)(dian)池(chi)应该(gai)储(chu)存在(zai)哪里(li)呢?储(chu)存理想环境是(shi)在(zai)一个(ge)(ge)凉爽的房(fang)间,周(zhou)围没有(you)易(yi)燃或(huo)磁性(xing)物体。将电(dian)(dian)池(chi)储(chu)存在(zai)非常热的地方(fang)会引起(qi)化学(xue)反(fan)应并(bing)损坏电(dian)(dian)池(chi)。如(ru)果有(you)一个(ge)(ge)防爆盒,可以(yi)把电(dian)(dian)池(chi)储(chu)存在(zai)里(li)面。
