锂电池与镍氢电池的比较

1、体积：可充(chong)电(dian)(dian)锂电(dian)(dian)池比普通的镍镉/镍氢电(dian)(dian)池的体积更(geng)小(相对)、更(geng)轻、自放(fang)电(dian)(dian)低(di)、无记(ji)忆(yi)效应(ying)的优(you)点，在许多新型(xing)移动设备中得到了广泛的应(ying)用，如手机(ji)、笔记(ji)本电(dian)(dian)脑、pda等移动设备的电(dian)(dian)池已经(jing)逐(zhu)渐被(bei)锂电(dian)(dian)池所取代。镍氢电(dian)(dian)池的记(ji)忆(yi)效果(guo)不(bu)是很(hen)明显，要紧急使用，不(bu)一定要完全放(fang)电(dian)(dian)再充(chong)电(dian)(dian)。

2、电(dian)量：锂电(dian)池(chi)能量大，体积小；单个(ge)锂电(dian)池(chi)的(de)(de)电(dian)压是镍氢电(dian)池(chi)的(de)(de)三倍，无记(ji)忆效应。它可以根据(ju)需要(yao)使(shi)用。充(chong)放(fang)电(dian)次数过多会(hui)影(ying)响电(dian)池(chi)的(de)(de)使(shi)用寿命。锂电(dian)池(chi)不(bu)宜长时间储存(cun)，长时间会(hui)永(yong)久失去部分容(rong)量。好充(chong)满40%的(de)(de)电(dian)，然后(hou)放(fang)在(zai)冰(bing)箱的(de)(de)冷冻室里。

3、充(chong)电(dian)(dian)(dian)(dian)(dian)方式：锂(li)电(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)电(dian)(dian)(dian)(dian)(dian)要(yao)求不(bu)同于镍(nie)镉/镍(nie)氢电(dian)(dian)(dian)(dian)(dian)池(chi)。可(ke)充(chong)电(dian)(dian)(dian)(dian)(dian)锂(li)电(dian)(dian)(dian)(dian)(dian)池(chi)电(dian)(dian)(dian)(dian)(dian)压为3.6V(部分电(dian)(dian)(dian)(dian)(dian)池(chi)块可(ke)能(neng)标为锂(li)电(dian)(dian)(dian)(dian)(dian)池(chi))。锂(li)电(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)电(dian)(dian)(dian)(dian)(dian)方式一般是限制(zhi)电(dian)(dian)(dian)(dian)(dian)压和电(dian)(dian)(dian)(dian)(dian)流。如果有朋友想单独给锂(li)电(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)电(dian)(dian)(dian)(dian)(dian)，需(xu)要(yao)注(zhu)意的(de)是，它(ta)的(de)充(chong)电(dian)(dian)(dian)(dian)(dian)方式不(bu)同于镍(nie)镉/镍(nie)氢电(dian)(dian)(dian)(dian)(dian)池(chi)使用(yong)的(de)恒流充(chong)电(dian)(dian)(dian)(dian)(dian)方式。普通镍(nie)镉/镍(nie)氢电(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)电(dian)(dian)(dian)(dian)(dian)器不(bu)能(neng)使用(yong)。镍(nie)氢电(dian)(dian)(dian)(dian)(dian)池(chi)和锂(li)电(dian)(dian)(dian)(dian)(dian)池(chi)虽然不(bu)同，但它(ta)们是现代时代的(de)新能(neng)源电(dian)(dian)(dian)(dian)(dian)池(chi)，在人类生活的(de)进步中发挥了不(bu)可(ke)替代的(de)作(zuo)用(yong)！
