锂(li)(li)电(dian)(dian)池(chi)(chi)使(shi)用时间(jian)过长，是(shi)续航时间(jian)会明显缩短，这(zhei)主(zhu)要是(shi)电(dian)(dian)池(chi)(chi)容量(liang)下降所导致的。那么造成锂(li)(li)电(dian)(dian)池(chi)(chi)容量(liang)下降的原因是(shi)什么呢？1、沉积的锂(li)(li)被包(bao)覆在负极表面，阻碍了(le)(le)锂(li)(li)嵌入(ru)，减少(shao)了(le)(le)可循(xun)环锂(li)(li)的用量(liang)，导致放电(dian)(dian)效率(lv)降低，终造成电(dian)(dian)池(chi)(chi)容量(liang)损失(shi)。2、金属锂(li)(li)通(tong)常形成于负极和隔膜之(zhi)间(jian)
