一、锂(li)电池的(de)可(ke)用容量可(ke)用容量可(ke)能只(zhi)能用80-90%。锂(li)电池的(de)化(hua)学容量是在(zai)电流(liu)很(hen)小(xiao)的(de)时候测(ce)量的(de),它更多的(de)是由电池本(ben)身的(de)特性决定的(de)。实(shi)际(ji)的(de),锂(li)电池在(zai)实(shi)际(ji)使用过程中,因为有一定的(de)放电电流(liu),放电曲线将低于开(kai)路电压(ya)曲线,这条(tiao)曲线可(ke)以看出,由于电池内阻的(de)存在(zai),实(shi)
锂(li)电(dian)(dian)(dian)池(chi)(chi)为什么会爆炸?1、过充(chong):当电(dian)(dian)(dian)压超过4.2V以上时(shi),电(dian)(dian)(dian)解液(ye)分解,产生大量气体(ti),电(dian)(dian)(dian)池(chi)(chi)压力升高(gao),过充(chong)负极表面锂(li)析(xi)出(chu),电(dian)(dian)(dian)池(chi)(chi)爆炸。2、高(gao)温环(huan)境:锂(li)电(dian)(dian)(dian)池(chi)(chi)在高(gao)温环(huan)境下使(shi)用会膨胀,电(dian)(dian)(dian)解液(ye)分解。3、保(bao)护系统故障外(wai)接(jie)电(dian)(dian)(dian)路短(duan)路:用户在使(shi)用时(shi),外(wai)接(jie)电(dian)(dian)(dian)路短(duan)路导致电(dian)(dian)(dian)池(chi)(chi)爆炸

磷酸(suan)铁锂(li)(li)电(dian)(dian)池(chi)的优势有(you)哪些?1、耐(nai)用(yong)性(xing):磷酸(suan)铁锂(li)(li)电(dian)(dian)池(chi)耐(nai)用(yong)性(xing)强,消耗慢,充放电(dian)(dian)1000次以上,且无(wu)记忆效应,一般寿命在5-8年。2、放电(dian)(dian)倍率:可放大(da)电(dian)(dian)流,适用(yong)于太阳能路灯(deng)、电(dian)(dian)动汽车(che)、电(dian)(dian)动自行(xing)车(che)等(deng)。3、体积(ji)、质量:锂(li)(li)电(dian)(dian)池(chi)体积(ji)比较小。4、电(dian)(dian)池(chi)容(rong)量:相同(tong)体积(ji)的
