鋰電池正確的充電方法

一、新電池充電

新電池一(yi)般要激(ji)(ji)(ji)活(huo)(huo)，電池放置(zhi)一(yi)段時間后，會進入休(xiu)眠狀態，此時容量低于正(zheng)常值(zhi)，使用時間亦隨之(zhi)縮短，因此需要激(ji)(ji)(ji)活(huo)(huo)。鋰電池激(ji)(ji)(ji)活(huo)(huo)方法非常簡單，只要經過3—5次正(zheng)常的充放電循環就可(ke)激(ji)(ji)(ji)活(huo)(huo)電池，恢(hui)復正(zheng)常容量。

二、舊電池充電

1、充電方法

舊電(dian)池(chi)(chi)是指已(yi)經充(chong)(chong)(chong)放電(dian)多次(ci)的電(dian)池(chi)(chi)，而不(bu)是報廢的電(dian)池(chi)(chi)。鋰電(dian)池(chi)(chi)的壽命與充(chong)(chong)(chong)放電(dian)的次(ci)數無關(guan)，它沒有記憶(yi)效應，不(bu)論你(ni)怎么充(chong)(chong)(chong)電(dian)，都不(bu)會(hui)影響充(chong)(chong)(chong)電(dian)循(xun)環次(ci)數。因此不(bu)要把電(dian)池(chi)(chi)用到完全沒電(dian)才去充(chong)(chong)(chong)電(dian)，最好是當你(ni)能(neng)充(chong)(chong)(chong)電(dian)時，就盡量把電(dian)池(chi)(chi)充(chong)(chong)(chong)飽(bao)，充(chong)(chong)(chong)電(dian)時間以(yi)2-3小時以(yi)內為宜，當然你(ni)也(ye)不(bu)一定非要充(chong)(chong)(chong)滿(man)。

2、充電電壓

鋰電(dian)(dian)(dian)池安(an)全工(gong)作電(dian)(dian)(dian)壓(ya)范(fan)圍(wei)是2.8到4.2V，低于(yu)或高于(yu)這個電(dian)(dian)(dian)壓(ya)范(fan)圍(wei)，電(dian)(dian)(dian)池中的(de)鋰離(li)子變(bian)得非常不穩(wen)定，甚(shen)至造成(cheng)事故。為保證電(dian)(dian)(dian)池處于(yu)安(an)全范(fan)圍(wei)，因(yin)此需要專門的(de)充電(dian)(dian)(dian)器。這些充電(dian)(dian)(dian)器會(hui)自(zi)動(dong)根據電(dian)(dian)(dian)池當前狀態(tai)而調整充電(dian)(dian)(dian)方式。

3、充電工具

鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)要用(yong)專用(yong)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，它可以(yi)保障(zhang)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)安(an)全性。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)工作時(shi)，以(yi)恒定(ding)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，隨著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)升(sheng)高(gao)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)同時(shi)提高(gao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，以(yi)加(jia)快充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度(du)。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)到達(da)4.2V截止電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓時(shi)候，此時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)大約(yue)僅沖入70%左(zuo)右的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量（并未(wei)飽滿）。此時(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)即以(yi)恒定(ding)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，逐漸變小的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)繼(ji)續充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當值至小于0.1A充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)仍然檢測到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓繼(ji)續升(sheng)高(gao)時(shi)候才停(ting)止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

4、定期充電

長期不用的鋰電(dian)(dian)(dian)(dian)池，應該以半(ban)電(dian)(dian)(dian)(dian)狀態(tai)，存(cun)放(fang)在(zai)陰涼(liang)偏(pian)干燥的地方。滿(man)電(dian)(dian)(dian)(dian)存(cun)放(fang)有(you)危險(xian)，且電(dian)(dian)(dian)(dian)池會有(you)損害(hai)，而無電(dian)(dian)(dian)(dian)存(cun)放(fang)，電(dian)(dian)(dian)(dian)池可能會被破(po)壞，從(cong)而失去作用。在(zai)存(cun)放(fang)過程(cheng)中(zhong)，每隔(ge)3--6個月，要(yao)完成一個充電(dian)(dian)(dian)(dian)周(zhou)期，做一次電(dian)(dian)(dian)(dian)量校準(zhun)。

鋰電池壽命一般有多長

鋰電(dian)(dian)(dian)(dian)(dian)池一般能夠完全充(chong)放300-500個(ge)(ge)(ge)(ge)充(chong)電(dian)(dian)(dian)(dian)(dian)周期(qi)，超過這個(ge)(ge)(ge)(ge)次(ci)(ci)數，電(dian)(dian)(dian)(dian)(dian)池就不能用(yong)(yong)了(le)，當然，這只(zhi)能作為(wei)參(can)考。鋰電(dian)(dian)(dian)(dian)(dian)池壽命(ming)和充(chong)電(dian)(dian)(dian)(dian)(dian)次(ci)(ci)數無(wu)關(guan)，與充(chong)放電(dian)(dian)(dian)(dian)(dian)的(de)周期(qi)有關(guan)，也(ye)就是從零電(dian)(dian)(dian)(dian)(dian)量(liang)充(chong)到(dao)滿(man)電(dian)(dian)(dian)(dian)(dian)量(liang)的(de)次(ci)(ci)數。一個(ge)(ge)(ge)(ge)充(chong)電(dian)(dian)(dian)(dian)(dian)周期(qi)意(yi)味著電(dian)(dian)(dian)(dian)(dian)池的(de)所有電(dian)(dian)(dian)(dian)(dian)量(liang)由滿(man)用(yong)(yong)到(dao)空(kong)，再由空(kong)充(chong)到(dao)滿(man)的(de)過程，這并(bing)不等同(tong)于充(chong)一次(ci)(ci)電(dian)(dian)(dian)(dian)(dian)。比(bi)如說，一塊(kuai)鋰電(dian)(dian)(dian)(dian)(dian)在第一天只(zhi)用(yong)(yong)了(le)一半(ban)的(de)電(dian)(dian)(dian)(dian)(dian)量(liang)，然后又為(wei)它充(chong)滿(man)電(dian)(dian)(dian)(dian)(dian)。如果第二天還如此，即用(yong)(yong)一半(ban)就充(chong)，總共兩(liang)次(ci)(ci)充(chong)電(dian)(dian)(dian)(dian)(dian)下來(lai)，這只(zhi)能算(suan)作一個(ge)(ge)(ge)(ge)充(chong)電(dian)(dian)(dian)(dian)(dian)周期(qi)，而(er)不是兩(liang)個(ge)(ge)(ge)(ge)。

在日常(chang)生活中，通常(chang)可能要(yao)經(jing)過好幾次充電(dian)(dian)才(cai)完成一個(ge)(ge)周期(qi)(qi)。每完成一個(ge)(ge)充電(dian)(dian)周期(qi)(qi)，電(dian)(dian)池容量(liang)就會減(jian)少(shao)一點(dian)。不過，這(zhe)個(ge)(ge)電(dian)(dian)量(liang)減(jian)少(shao)幅度非常(chang)小(xiao)，高品質的(de)電(dian)(dian)池充過多次周期(qi)(qi)后(hou)，仍(reng)(reng)然(ran)會保留原始容量(liang)的(de)80%，很多鋰(li)電(dian)(dian)供電(dian)(dian)產品在經(jing)過兩三年后(hou)仍(reng)(reng)然(ran)照常(chang)使用。當然(ran)，鋰(li)電(dian)(dian)壽(shou)命到了最(zui)終后(hou)仍(reng)(reng)是需要(yao)更(geng)換的(de)。
