聚(ju)合物软包锂电(dian)(dian)池充电(dian)(dian)应到4.1伏(fu)特(te),而不是4.2伏(fu)特(te),并且(qie)永远不要(yao)将电(dian)(dian)池放(fang)电(dian)(dian)达(da)到彻底(di)的状态。在充电(dian)(dian)/放(fang)电(dian)(dian)水(shui)平两(liang)端之间(jian)操作聚(ju)合物软包锂电(dian)(dian)池将大(da)大(da)延长其(qi)使(shi)用寿(shou)命。
有几个条件可(ke)以(yi)导致(zhi)聚合物(wu)软包锂电池(chi)的(de)退(tui)化,其(qi)中影(ying)响(xiang)大的(de)是热(re)量,以(yi)达到RC建模目的(de)。其(qi)他因素与电荷状态和两端材料的(de)影(ying)响(xiang)有关。
在充电过程中(zhong)(zhong)的(de)(de)两端,锂(li)离子被(bei)强迫进入平板(ban)上的(de)(de)碳材料(liao)。这(zhei)将导致材料(liao)的(de)(de)破坏,并(bing)且在未来的(de)(de)充电周期中(zhong)(zhong)可(ke)以保(bao)留的(de)(de)离子更少(shao),从而导致容量减少(shao)。这(zhei)种损坏主要发生在末端,所以远离它们有利于延(yan)长锂(li)电池的(de)(de)寿命。
有些充(chong)电器在每节(jie)锂(li)电池上以4.1V电压停止充(chong)电,可以看出,使用(yong)4.1伏(fu)特(te)(te)(te)会(hui)使你(ni)(ni)远离高(gao)伏(fu)特(te)(te)(te),而(er)锂(li)电池充(chong)电高(gao)于(yu)传统的(de)3伏(fu)特(te)(te)(te)会(hui)使你(ni)(ni)远离低(di)伏(fu)特(te)(te)(te)。这将延长(zhang)你(ni)(ni)的(de)聚合物(wu)软包锂(li)电池的(de)使用(yong)寿命。
