聚合物锂离子电池的充电激活

2022-08-27

聚合物锂离子电池

聚合物(wu)锂离子(zi)电(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)激(ji)活(huo)问题一(yi)直存(cun)在争议。有网友认为一(yi)般锂离子(zi)电(dian)(dian)(dian)(dian)(dian)池(chi)不(bu)需要激(ji)活(huo),假(jia)设电(dian)(dian)(dian)(dian)(dian)池(chi)搁(ge)置(zhi)时间(jian)太长,可以(yi)充电(dian)(dian)(dian)(dian)(dian)完毕后再充电(dian)(dian)(dian)(dian)(dian)几个小(xiao)时。初的(de)(de)(de)镍镉电(dian)(dian)(dian)(dian)(dian)池(chi)充电(dian)(dian)(dian)(dian)(dian)三次12小(xiao)时,锂离子(zi)电(dian)(dian)(dian)(dian)(dian)池(chi)则不(bu)然(ran)(ran),因为它们没有记忆(yi)效应。有专家(jia)说过:一(yi)般的(de)(de)(de)工(gong)艺需要一(yi)段时间(jian)进(jin)行小(xiao)电(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)充电(dian)(dian)(dian)(dian)(dian)和(he)释放(fang),才能(neng)形成电(dian)(dian)(dian)(dian)(dian)极(ji)表面(mian)的(de)(de)(de)SEI膜(mo),这(zhei)当然(ran)(ran)是(shi)普通用(yong)户的(de)(de)(de)充电(dian)(dian)(dian)(dian)(dian)器无法完成的(de)(de)(de),如果真的(de)(de)(de)有激(ji)活(huo)这(zhei)个说法,那(nei)么厂(chang)家(jia)怎么可能(neng)给用(yong)户完成这(zhei)么重要的(de)(de)(de)工(gong)艺呢?

因(yin)此,有(you)用户(hu)表(biao)示(shi):根据实(shi)际经验,锂(li)电池需要激(ji)(ji)活,因(yin)为记(ji)忆效应是不(bu)(bu)可恢(hui)复的(de),但如果锂(li)电池不(bu)(bu)激(ji)(ji)活,容量(liang)不(bu)(bu)足(zu)的(de)问(wen)题是可以恢(hui)复的(de)。任(ren)何数码设备(bei)的(de)标(biao)准(zhun)配备(bei)都必须(xu)在使(shi)用时激(ji)(ji)活锂(li)电池。很多用户(hu)在使(shi)用锂(li)电池的(de)过程中,没(mei)有(you)科学激(ji)(ji)活,导致锂(li)电池无法(fa)达到佳容量(liang),容易(yi)让人误以为这是记(ji)忆效应。

一般电池的激活过(guo)程(cheng)如下:

激(ji)活过程一(yi)(yi):刚使(shi)用(yong)锂电(dian)一(yi)(yi)般有剩余电(dian)量,此时不(bu)(bu)要充电(dian)。把电(dian)池放(fang)入(ru)产品,使(shi)用(yong)它(ta),直到(dao)它(ta)电(dian)量低到(dao)不(bu)(bu)能打开。

激活过程(cheng)二:次充(chong)(chong)(chong)电(dian),好是用(yong)原(yuan)装的充(chong)(chong)(chong)电(dian)器充(chong)(chong)(chong)电(dian),而关(guan)机(ji)充(chong)(chong)(chong)电(dian)比较好,很多人为(wei)了方便(bian)使用(yong),不(bu)关(guan)机(ji)充(chong)(chong)(chong)电(dian),这样不(bu)利于(yu)锂容(rong)量的激活。

激活过程三:次(ci)充满(man)电后,如果(guo)正常使用直到无(wu)法开机(ji)。您可以再次(ci)按过程二继续操(cao)作(zuo)。

激(ji)活过程四:完(wan)全放电(dian)、完(wan)全充电(dian)(即重复过程二和(he)过程三)重复三次。此(ci)时电(dian)池(chi)激(ji)活成功,可以达到佳(jia)容量状(zhuang)态。

注意事项:锂电池(chi)在(zai)出厂(chang)时一般(ban)已经(jing)被激活(huo),所以(yi)买家不需要再次(ci)激活(huo)。
