以前由于技術水平的關系，普及使用的鎳鎘電池充電時有諸多要求，使得很多現在的人給鋰電池第一次充電的時候會按照鎳鎘電池要求來，那么鋰電池第一次充電的方法是什么呢？

1、新鋰電(dian)池(chi)(chi)到(dao)手后(hou)一(yi)(yi)般都(dou)帶有一(yi)(yi)定的電(dian)量(liang)，可以(yi)(yi)立即(ji)使用(yong)，而不(bu)是一(yi)(yi)定要先充電(dian)再使用(yong)，從理論和實踐來看，鋰電(dian)池(chi)(chi)首次充電(dian)是采取“用(yong)后(hou)再充”還是“充后(hou)再用(yong)”的效果完全一(yi)(yi)樣。但是要注意的是出廠日期達到(dao)半年(nian)以(yi)(yi)上的鋰電(dian)池(chi)(chi)最(zui)好先充電(dian)，因為此時電(dian)量(liang)過低。

在(zai)鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)停充(chong)(chong)后(hou)要立即將鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)與充(chong)(chong)電(dian)(dian)(dian)器(qi)分離。鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)在(zai)充(chong)(chong)滿(man)（暫時性的）后(hou)會自動停充(chong)(chong)，而并不(bu)存(cun)在(zai)“持續(xu)”時間(jian)很長的涓流充(chong)(chong)電(dian)(dian)(dian)，這就是鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)與鎳鎘(ge)電(dian)(dian)(dian)池(chi)(chi)(chi)的不(bu)同處(chu)。充(chong)(chong)電(dian)(dian)(dian)器(qi)充(chong)(chong)滿(man)指示燈(deng)亮后(hou)，如果不(bu)立即取下的話，由(you)于電(dian)(dian)(dian)池(chi)(chi)(chi)自放(fang)電(dian)(dian)(dian)和鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)保護IC仍有小電(dian)(dian)(dian)流通(tong)過(guo)，會使鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓因(yin)此(ci)而降到可以充(chong)(chong)電(dian)(dian)(dian)的電(dian)(dian)(dian)壓值后(hou)重新充(chong)(chong)電(dian)(dian)(dian)（因(yin)為(wei)此(ci)時充(chong)(chong)電(dian)(dian)(dian)器(qi)未取下），經過(guo)又一輪的“充(chong)(chong)電(dian)(dian)(dian)——電(dian)(dian)(dian)壓下降——再充(chong)(chong)電(dian)(dian)(dian)”，使得鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)處(chu)在(zai)無(wu)數次的充(chong)(chong)放(fang)電(dian)(dian)(dian)循環過(guo)程(cheng)當中(zhong)，最終損害鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)，影響(xiang)鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)壽命。

2、關機充(chong)(chong)電(dian)與開機充(chong)(chong)電(dian)（實際上(shang)也是(shi)(shi)插充(chong)(chong)與座充(chong)(chong)方(fang)法形式之(zhi)別）的(de)選擇不必刻(ke)意，因為對電(dian)池性能的(de)影響是(shi)(shi)一樣的(de)，有些鋰(li)電(dian)池將充(chong)(chong)電(dian)設計在待機狀態(tai)下，但這(zhe)種(zhong)情況(kuang)相對較少。

3、就(jiu)電子設備而言，在用鋰電池充電時(shi)(shi)間一般(ban)為2~4個小時(shi)(shi)，新鋰電池首(shou)次充電時(shi)(shi)間可能會長(chang)些，因為沒有任何的容量損失，結果上也是滿電即可，多充也是無(wu)用，上面已經說(shuo)過(guo)原因，如果非(fei)要(yao)說(shuo)有什么作用的話，也是副作用。

鋰(li)電(dian)池(chi)第一(yi)次(ci)(ci)充(chong)電(dian)時(shi)間往(wang)往(wang)會(hui)被(bei)轉化為(wei)“激活”的(de)概念，有些鋰(li)電(dian)池(chi)說明書(shu)中首次(ci)(ci)使用鋰(li)電(dian)池(chi)進行三次(ci)(ci)完(wan)全充(chong)放電(dian)的(de)要求貌(mao)似激活，真實目(mu)的(de)卻與(yu)鎳(nie)氫電(dian)池(chi)消(xiao)除記憶效應(ying)并不(bu)一(yi)樣，這(zhe)樣做(zuo)主要是(shi)為(wei)了消(xiao)除“鈍(dun)化”，即鋰(li)電(dian)池(chi)在(zai)長達3~6個月的(de)中轉過程中會(hui)產(chan)生一(yi)些鋰(li)結(jie)晶，從(cong)而(er)影(ying)響活性。消(xiao)除鈍(dun)化的(de)過程可(ke)(ke)以在(zai)鋰(li)電(dian)池(chi)第一(yi)次(ci)(ci)充(chong)電(dian)中進行，也可(ke)(ke)以在(zai)正常的(de)工(gong)作環境中完(wan)成，不(bu)必刻意為(wei)之。

4、充(chong)滿即可：鋰電池(chi)第一次使用(yong)時不(bu)存在(zai)(zai)“激活(huo)”問題，原因在(zai)(zai)于(yu)(yu)：鋰電池(chi)和鎳氫電池(chi)的充(chong)放(fang)電特(te)性有(you)非常大的區別，更深(shen)層的原因還在(zai)(zai)于(yu)(yu)，過充(chong)會(hui)對鋰電池(chi)特(te)別是液(ye)態鋰離子電池(chi)造成極大的傷害(hai)，因而，充(chong)電應按標(biao)(biao)準時間和標(biao)(biao)準方法(fa)充(chong)電，千萬不(bu)要(yao)進行超(chao)長充(chong)電。
