鋰電池正確的充電方法

一、新電池充電

新電(dian)(dian)池一般要(yao)激活(huo)，電(dian)(dian)池放置一段時(shi)間后(hou)，會進(jin)入休(xiu)眠狀(zhuang)態，此時(shi)容(rong)量(liang)低(di)于(yu)正常(chang)值(zhi)，使用時(shi)間亦隨之縮短，因此需(xu)要(yao)激活(huo)。鋰電(dian)(dian)池激活(huo)方法非(fei)常(chang)簡單，只要(yao)經過3—5次正常(chang)的充放電(dian)(dian)循環就可激活(huo)電(dian)(dian)池，恢復正常(chang)容(rong)量(liang)。

二、舊電池充電

1、充電方法

舊電(dian)(dian)(dian)池(chi)是(shi)指(zhi)已經充放電(dian)(dian)(dian)多次的電(dian)(dian)(dian)池(chi)，而(er)不是(shi)報廢的電(dian)(dian)(dian)池(chi)。鋰電(dian)(dian)(dian)池(chi)的壽命與(yu)充放電(dian)(dian)(dian)的次數(shu)無關，它沒有(you)記憶效應，不論你(ni)怎么充電(dian)(dian)(dian)，都不會影(ying)響充電(dian)(dian)(dian)循環(huan)次數(shu)。因(yin)此不要(yao)(yao)把電(dian)(dian)(dian)池(chi)用到完(wan)全沒電(dian)(dian)(dian)才去充電(dian)(dian)(dian)，最好是(shi)當你(ni)能充電(dian)(dian)(dian)時，就盡量把電(dian)(dian)(dian)池(chi)充飽(bao)，充電(dian)(dian)(dian)時間以(yi)2-3小時以(yi)內為宜，當然你(ni)也不一(yi)定非要(yao)(yao)充滿(man)。

2、充電電壓

鋰電(dian)(dian)(dian)池安(an)全工作電(dian)(dian)(dian)壓范(fan)圍是(shi)2.8到4.2V，低于(yu)或高于(yu)這個電(dian)(dian)(dian)壓范(fan)圍，電(dian)(dian)(dian)池中的鋰離子變得非常不(bu)穩定，甚至造成事(shi)故。為保證(zheng)電(dian)(dian)(dian)池處(chu)于(yu)安(an)全范(fan)圍，因(yin)此需要專(zhuan)門的充(chong)電(dian)(dian)(dian)器。這些充(chong)電(dian)(dian)(dian)器會自動(dong)根(gen)據電(dian)(dian)(dian)池當前狀(zhuang)態而調整(zheng)充(chong)電(dian)(dian)(dian)方式。

3、充電工具

鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)要用專用的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，它可(ke)以(yi)保障充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)安(an)全性。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器工作時，以(yi)恒(heng)定(ding)的(de)(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)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)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)升高(gao)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器同(tong)時提高(gao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，以(yi)加(jia)快充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)到達4.2V截止(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)時候，此時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)大約僅沖入70%左右的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量（并未飽滿）。此時充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器即以(yi)恒(heng)定(ding)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，逐漸變小(xiao)的(de)(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)繼續(xu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當值至小(xiao)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)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)繼續(xu)升高(gao)時候才停止(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

4、定期充電

長期不用的(de)(de)鋰電(dian)(dian)池，應(ying)該以半電(dian)(dian)狀態，存放在(zai)陰涼(liang)偏干燥的(de)(de)地(di)方。滿電(dian)(dian)存放有(you)危(wei)險(xian)，且電(dian)(dian)池會有(you)損害，而無電(dian)(dian)存放，電(dian)(dian)池可能會被破壞，從而失去作用。在(zai)存放過程中，每(mei)隔3--6個月，要(yao)完成一個充電(dian)(dian)周(zhou)期，做一次(ci)電(dian)(dian)量校準。

鋰電池壽命一般有多長

鋰(li)電(dian)(dian)(dian)(dian)池(chi)一般(ban)能(neng)夠(gou)完全充放(fang)300-500個充電(dian)(dian)(dian)(dian)周(zhou)期(qi)(qi)，超(chao)過這個次(ci)(ci)(ci)數(shu)(shu)，電(dian)(dian)(dian)(dian)池(chi)就(jiu)不(bu)能(neng)用了，當然，這只能(neng)作(zuo)(zuo)為參考。鋰(li)電(dian)(dian)(dian)(dian)池(chi)壽命和充電(dian)(dian)(dian)(dian)次(ci)(ci)(ci)數(shu)(shu)無關，與充放(fang)電(dian)(dian)(dian)(dian)的(de)(de)周(zhou)期(qi)(qi)有關，也就(jiu)是從零電(dian)(dian)(dian)(dian)量(liang)充到滿電(dian)(dian)(dian)(dian)量(liang)的(de)(de)次(ci)(ci)(ci)數(shu)(shu)。一個充電(dian)(dian)(dian)(dian)周(zhou)期(qi)(qi)意味著電(dian)(dian)(dian)(dian)池(chi)的(de)(de)所(suo)有電(dian)(dian)(dian)(dian)量(liang)由滿用到空，再由空充到滿的(de)(de)過程，這并不(bu)等同于充一次(ci)(ci)(ci)電(dian)(dian)(dian)(dian)。比如說，一塊鋰(li)電(dian)(dian)(dian)(dian)在第一天只用了一半的(de)(de)電(dian)(dian)(dian)(dian)量(liang)，然后又為它充滿電(dian)(dian)(dian)(dian)。如果第二天還如此，即(ji)用一半就(jiu)充，總(zong)共兩次(ci)(ci)(ci)充電(dian)(dian)(dian)(dian)下來(lai)，這只能(neng)算作(zuo)(zuo)一個充電(dian)(dian)(dian)(dian)周(zhou)期(qi)(qi)，而不(bu)是兩個。

在日常生(sheng)活(huo)中，通常可能要(yao)經過(guo)(guo)好幾(ji)次充電(dian)才完(wan)成一個(ge)(ge)周期。每完(wan)成一個(ge)(ge)充電(dian)周期，電(dian)池(chi)容量就會(hui)減少一點。不過(guo)(guo)，這(zhe)個(ge)(ge)電(dian)量減少幅度非常小，高品(pin)質的電(dian)池(chi)充過(guo)(guo)多次周期后(hou)，仍(reng)然會(hui)保(bao)留原始容量的80%，很多鋰(li)電(dian)供電(dian)產(chan)品(pin)在經過(guo)(guo)兩三年后(hou)仍(reng)然照(zhao)常使用。當然，鋰(li)電(dian)壽命(ming)到了最終后(hou)仍(reng)是需要(yao)更換的。
