鋰電池正確的充電方法

一、新電池充電

新(xin)電(dian)(dian)池(chi)一般要激活(huo)，電(dian)(dian)池(chi)放置一段時(shi)間后，會進入(ru)休眠狀態，此時(shi)容量(liang)低于(yu)正(zheng)常值，使(shi)用時(shi)間亦隨之縮短，因此需要激活(huo)。鋰電(dian)(dian)池(chi)激活(huo)方法非常簡單，只(zhi)要經過3—5次(ci)正(zheng)常的充放電(dian)(dian)循環就可激活(huo)電(dian)(dian)池(chi)，恢(hui)復(fu)正(zheng)常容量(liang)。

二、舊電池充電

1、充電方法

舊電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)指已經充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)多(duo)次的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)，而不(bu)是(shi)(shi)報廢(fei)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)。鋰電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)壽命與充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)的(de)次數無關，它沒有記憶效應，不(bu)論你怎么充(chong)(chong)電(dian)(dian)(dian)(dian)，都不(bu)會影響充(chong)(chong)電(dian)(dian)(dian)(dian)循環次數。因此(ci)不(bu)要(yao)(yao)把電(dian)(dian)(dian)(dian)池(chi)(chi)用到(dao)完全沒電(dian)(dian)(dian)(dian)才去充(chong)(chong)電(dian)(dian)(dian)(dian)，最好是(shi)(shi)當你能充(chong)(chong)電(dian)(dian)(dian)(dian)時，就盡量把電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)飽，充(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)以(yi)(yi)2-3小時以(yi)(yi)內為宜(yi)，當然你也不(bu)一定非要(yao)(yao)充(chong)(chong)滿。

2、充電電壓

鋰(li)電(dian)(dian)(dian)池安全(quan)(quan)工作電(dian)(dian)(dian)壓范(fan)圍是(shi)2.8到4.2V，低(di)于(yu)或高于(yu)這(zhe)個電(dian)(dian)(dian)壓范(fan)圍，電(dian)(dian)(dian)池中的鋰(li)離子(zi)變得非常(chang)不穩定，甚至造成事故。為保(bao)證電(dian)(dian)(dian)池處于(yu)安全(quan)(quan)范(fan)圍，因此需要(yao)專門(men)的充電(dian)(dian)(dian)器。這(zhe)些充電(dian)(dian)(dian)器會(hui)自動(dong)根據電(dian)(dian)(dian)池當前狀態而(er)調整充電(dian)(dian)(dian)方式。

3、充電工具

鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)要用專(zhuan)用的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器，它(ta)可以(yi)(yi)保障充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)安全性。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器工(gong)作時(shi)(shi)，以(yi)(yi)恒(heng)定的(de)(de)電(dian)(dian)(dian)(dian)(dian)流給(gei)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，隨著電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)升高(gao)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器同時(shi)(shi)提高(gao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)，以(yi)(yi)加快充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)速度。當(dang)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)到(dao)達4.2V截止電(dian)(dian)(dian)(dian)(dian)壓(ya)時(shi)(shi)候，此時(shi)(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)大約僅沖(chong)入70%左右的(de)(de)電(dian)(dian)(dian)(dian)(dian)量(liang)（并未飽滿）。此時(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器即(ji)以(yi)(yi)恒(heng)定的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)，逐(zhu)漸變小的(de)(de)電(dian)(dian)(dian)(dian)(dian)流對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)繼(ji)續(xu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，當(dang)值(zhi)至小于(yu)0.1A充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)仍然檢測到(dao)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)繼(ji)續(xu)升高(gao)時(shi)(shi)候才停(ting)止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。

4、定期充電

長期不用的鋰電(dian)(dian)池，應該以半電(dian)(dian)狀態，存(cun)放(fang)在陰涼偏干燥的地(di)方。滿(man)電(dian)(dian)存(cun)放(fang)有(you)危險，且電(dian)(dian)池會有(you)損害，而(er)(er)無電(dian)(dian)存(cun)放(fang)，電(dian)(dian)池可能會被破壞，從(cong)而(er)(er)失去(qu)作用。在存(cun)放(fang)過程中，每隔(ge)3--6個(ge)月，要完(wan)成一(yi)個(ge)充電(dian)(dian)周(zhou)期，做一(yi)次電(dian)(dian)量校準(zhun)。

鋰電池壽命一般有多長

鋰電(dian)池一(yi)(yi)(yi)般(ban)能夠完全充放300-500個充電(dian)周期，超過這(zhe)個次數(shu)，電(dian)池就(jiu)不能用了，當然，這(zhe)只(zhi)(zhi)能作(zuo)為參考(kao)。鋰電(dian)池壽命和充電(dian)次數(shu)無關(guan)，與(yu)充放電(dian)的(de)(de)周期有(you)關(guan)，也就(jiu)是(shi)從零(ling)電(dian)量(liang)充到(dao)滿(man)電(dian)量(liang)的(de)(de)次數(shu)。一(yi)(yi)(yi)個充電(dian)周期意味(wei)著電(dian)池的(de)(de)所(suo)有(you)電(dian)量(liang)由滿(man)用到(dao)空，再由空充到(dao)滿(man)的(de)(de)過程，這(zhe)并不等同于充一(yi)(yi)(yi)次電(dian)。比如(ru)說，一(yi)(yi)(yi)塊鋰電(dian)在第(di)一(yi)(yi)(yi)天(tian)只(zhi)(zhi)用了一(yi)(yi)(yi)半的(de)(de)電(dian)量(liang)，然后又為它充滿(man)電(dian)。如(ru)果第(di)二天(tian)還(huan)如(ru)此，即用一(yi)(yi)(yi)半就(jiu)充，總共兩次充電(dian)下來，這(zhe)只(zhi)(zhi)能算作(zuo)一(yi)(yi)(yi)個充電(dian)周期，而不是(shi)兩個。

在(zai)日常(chang)生活中，通常(chang)可能要(yao)經過好(hao)幾次(ci)充(chong)電(dian)才完(wan)成(cheng)一個(ge)(ge)周期(qi)。每完(wan)成(cheng)一個(ge)(ge)充(chong)電(dian)周期(qi)，電(dian)池(chi)(chi)容量就會減少一點。不過，這個(ge)(ge)電(dian)量減少幅(fu)度非常(chang)小，高品質的電(dian)池(chi)(chi)充(chong)過多(duo)次(ci)周期(qi)后，仍(reng)然會保留原(yuan)始容量的80%，很多(duo)鋰(li)(li)電(dian)供電(dian)產品在(zai)經過兩三年(nian)后仍(reng)然照(zhao)常(chang)使用。當然，鋰(li)(li)電(dian)壽(shou)命到(dao)了最(zui)終后仍(reng)是需要(yao)更換的。
