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(yao)(yao)激活，電(dian)(dian)池(chi)放置一段時(shi)間后，會進入休眠狀態，此(ci)時(shi)容量(liang)低于正常(chang)值，使用時(shi)間亦隨之縮短(duan)，因此(ci)需要(yao)(yao)激活。鋰電(dian)(dian)池(chi)激活方(fang)法非常(chang)簡單，只要(yao)(yao)經過3—5次正常(chang)的充放電(dian)(dian)循環就(jiu)可激活電(dian)(dian)池(chi)，恢(hui)復(fu)正常(chang)容量(liang)。

二、舊電池充電

1、充電方法

舊(jiu)電(dian)(dian)池是(shi)指已經充(chong)放電(dian)(dian)多次的電(dian)(dian)池，而不(bu)(bu)是(shi)報廢(fei)的電(dian)(dian)池。鋰電(dian)(dian)池的壽命(ming)與充(chong)放電(dian)(dian)的次數無關，它沒(mei)有記憶效應，不(bu)(bu)論(lun)你怎么充(chong)電(dian)(dian)，都不(bu)(bu)會影響充(chong)電(dian)(dian)循(xun)環次數。因此(ci)不(bu)(bu)要把(ba)電(dian)(dian)池用到完全沒(mei)電(dian)(dian)才去充(chong)電(dian)(dian)，最好(hao)是(shi)當你能充(chong)電(dian)(dian)時(shi)(shi)，就盡量(liang)把(ba)電(dian)(dian)池充(chong)飽，充(chong)電(dian)(dian)時(shi)(shi)間以(yi)2-3小時(shi)(shi)以(yi)內為宜，當然(ran)你也不(bu)(bu)一定非要充(chong)滿。

2、充電電壓

鋰電(dian)(dian)(dian)(dian)(dian)池(chi)安(an)全工作電(dian)(dian)(dian)(dian)(dian)壓范(fan)圍(wei)是2.8到4.2V，低于(yu)(yu)或(huo)高于(yu)(yu)這個電(dian)(dian)(dian)(dian)(dian)壓范(fan)圍(wei)，電(dian)(dian)(dian)(dian)(dian)池(chi)中的鋰離(li)子變得非常(chang)不穩(wen)定(ding)，甚(shen)至造(zao)成事故(gu)。為(wei)保證(zheng)電(dian)(dian)(dian)(dian)(dian)池(chi)處于(yu)(yu)安(an)全范(fan)圍(wei)，因此需要(yao)專門的充(chong)電(dian)(dian)(dian)(dian)(dian)器。這些(xie)充(chong)電(dian)(dian)(dian)(dian)(dian)器會自動(dong)根據電(dian)(dian)(dian)(dian)(dian)池(chi)當(dang)前狀態(tai)而調整充(chong)電(dian)(dian)(dian)(dian)(dian)方(fang)式(shi)。

3、充電工具

鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)要用(yong)專用(yong)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，它可以(yi)(yi)(yi)保障充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)安全性。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)工作時(shi)，以(yi)(yi)(yi)恒定(ding)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，隨著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)升(sheng)高，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)同時(shi)提高充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，以(yi)(yi)(yi)加快充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度(du)。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池到(dao)達4.2V截(jie)止(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時(shi)候(hou)，此(ci)(ci)時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池大約(yue)僅(jin)沖入70%左右(you)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量（并未飽滿）。此(ci)(ci)時(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)即以(yi)(yi)(yi)恒定(ding)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，逐漸變(bian)小(xiao)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池繼(ji)續(xu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當值至(zhi)小(xiao)于0.1A充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)仍然檢測到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)繼(ji)續(xu)升(sheng)高時(shi)候(hou)才停(ting)止(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

4、定期充電

長期不用的(de)鋰(li)電(dian)(dian)池(chi)，應該以半電(dian)(dian)狀態，存(cun)放(fang)在陰(yin)涼偏干燥的(de)地方。滿(man)電(dian)(dian)存(cun)放(fang)有(you)危險(xian)，且電(dian)(dian)池(chi)會(hui)有(you)損害(hai)，而(er)(er)無電(dian)(dian)存(cun)放(fang)，電(dian)(dian)池(chi)可能會(hui)被破(po)壞，從而(er)(er)失去作用。在存(cun)放(fang)過程中，每隔3--6個(ge)(ge)月，要完成一個(ge)(ge)充電(dian)(dian)周期，做一次電(dian)(dian)量校準。

鋰電池壽命一般有多長

鋰電(dian)(dian)(dian)(dian)(dian)池一(yi)般(ban)能夠完全充(chong)(chong)(chong)(chong)(chong)放300-500個(ge)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期，超過這個(ge)次(ci)數，電(dian)(dian)(dian)(dian)(dian)池就(jiu)不能用(yong)(yong)了(le)，當(dang)然，這只能作為(wei)參考。鋰電(dian)(dian)(dian)(dian)(dian)池壽命和充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)次(ci)數無關，與充(chong)(chong)(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)的周(zhou)(zhou)期有關，也就(jiu)是從零電(dian)(dian)(dian)(dian)(dian)量充(chong)(chong)(chong)(chong)(chong)到(dao)滿(man)(man)電(dian)(dian)(dian)(dian)(dian)量的次(ci)數。一(yi)個(ge)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期意味著電(dian)(dian)(dian)(dian)(dian)池的所有電(dian)(dian)(dian)(dian)(dian)量由(you)滿(man)(man)用(yong)(yong)到(dao)空(kong)，再(zai)由(you)空(kong)充(chong)(chong)(chong)(chong)(chong)到(dao)滿(man)(man)的過程，這并不等同于充(chong)(chong)(chong)(chong)(chong)一(yi)次(ci)電(dian)(dian)(dian)(dian)(dian)。比如說(shuo)，一(yi)塊鋰電(dian)(dian)(dian)(dian)(dian)在(zai)第一(yi)天只用(yong)(yong)了(le)一(yi)半的電(dian)(dian)(dian)(dian)(dian)量，然后又為(wei)它充(chong)(chong)(chong)(chong)(chong)滿(man)(man)電(dian)(dian)(dian)(dian)(dian)。如果第二天還如此，即用(yong)(yong)一(yi)半就(jiu)充(chong)(chong)(chong)(chong)(chong)，總共兩(liang)次(ci)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)下來(lai)，這只能算作一(yi)個(ge)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期，而不是兩(liang)個(ge)。

在日常(chang)生活中(zhong)，通常(chang)可能要經過(guo)好幾(ji)次(ci)充(chong)(chong)電(dian)才(cai)完成一(yi)(yi)個(ge)周期(qi)。每完成一(yi)(yi)個(ge)充(chong)(chong)電(dian)周期(qi)，電(dian)池容量就會減少一(yi)(yi)點。不過(guo)，這(zhe)個(ge)電(dian)量減少幅(fu)度非常(chang)小，高品(pin)質的電(dian)池充(chong)(chong)過(guo)多(duo)次(ci)周期(qi)后(hou)，仍然(ran)(ran)會保留原(yuan)始容量的80%，很多(duo)鋰電(dian)供電(dian)產品(pin)在經過(guo)兩(liang)三年后(hou)仍然(ran)(ran)照常(chang)使用。當然(ran)(ran)，鋰電(dian)壽命到了最終后(hou)仍是需(xu)要更換的。
