鋰電池正確的充電方法

一、新電池充電

新(xin)電(dian)池(chi)一般要激活，電(dian)池(chi)放置一段時間后，會進入休眠(mian)狀態，此時容量低于正(zheng)常(chang)值，使用時間亦隨之縮短(duan)，因此需要激活。鋰電(dian)池(chi)激活方法非(fei)常(chang)簡單(dan)，只要經過(guo)3—5次正(zheng)常(chang)的充放電(dian)循環(huan)就可激活電(dian)池(chi)，恢復正(zheng)常(chang)容量。

二、舊電池充電

1、充電方法

舊電(dian)(dian)池(chi)是指已經充(chong)(chong)放(fang)電(dian)(dian)多次的電(dian)(dian)池(chi)，而不(bu)(bu)是報廢的電(dian)(dian)池(chi)。鋰電(dian)(dian)池(chi)的壽命與充(chong)(chong)放(fang)電(dian)(dian)的次數(shu)無關，它(ta)沒有(you)記憶(yi)效(xiao)應，不(bu)(bu)論你(ni)怎(zen)么充(chong)(chong)電(dian)(dian)，都不(bu)(bu)會影響充(chong)(chong)電(dian)(dian)循環次數(shu)。因此(ci)不(bu)(bu)要(yao)把電(dian)(dian)池(chi)用到完全沒電(dian)(dian)才(cai)去充(chong)(chong)電(dian)(dian)，最好是當(dang)你(ni)能(neng)充(chong)(chong)電(dian)(dian)時(shi)，就盡(jin)量把電(dian)(dian)池(chi)充(chong)(chong)飽，充(chong)(chong)電(dian)(dian)時(shi)間以(yi)2-3小時(shi)以(yi)內為(wei)宜，當(dang)然你(ni)也不(bu)(bu)一定非(fei)要(yao)充(chong)(chong)滿(man)。

2、充電電壓

鋰電(dian)(dian)池安全(quan)工作電(dian)(dian)壓(ya)范(fan)(fan)圍是2.8到4.2V，低于或高于這(zhe)個電(dian)(dian)壓(ya)范(fan)(fan)圍，電(dian)(dian)池中的鋰離子變得非常不(bu)穩定，甚至造成(cheng)事故(gu)。為保證電(dian)(dian)池處于安全(quan)范(fan)(fan)圍，因此需要專(zhuan)門的充電(dian)(dian)器。這(zhe)些充電(dian)(dian)器會(hui)自動(dong)根(gen)據電(dian)(dian)池當前狀態而調整充電(dian)(dian)方(fang)式(shi)。

3、充電工具

鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)要用專用的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，它(ta)可(ke)以(yi)保障充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的安全性。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)工作時，以(yi)恒定(ding)的電(dian)(dian)(dian)(dian)(dian)流給電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，隨著電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)的升高(gao)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)同時提高(gao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)，以(yi)加快充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)速度。當電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)到達4.2V截止(zhi)電(dian)(dian)(dian)(dian)(dian)壓(ya)時候(hou)，此時電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)大(da)約僅沖入70%左右的電(dian)(dian)(dian)(dian)(dian)量（并未飽滿）。此時充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)即(ji)以(yi)恒定(ding)的電(dian)(dian)(dian)(dian)(dian)壓(ya)，逐漸變小(xiao)的電(dian)(dian)(dian)(dian)(dian)流對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)繼續(xu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，當值(zhi)至(zhi)小(xiao)于0.1A充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)仍然檢(jian)測到電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)繼續(xu)升高(gao)時候(hou)才停止(zhi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。

4、定期充電

長期不用(yong)(yong)的鋰(li)電(dian)(dian)池，應該以半電(dian)(dian)狀態(tai)，存放(fang)在(zai)陰(yin)涼偏干燥的地方。滿電(dian)(dian)存放(fang)有(you)危險，且電(dian)(dian)池會有(you)損害，而無(wu)電(dian)(dian)存放(fang)，電(dian)(dian)池可能(neng)會被破壞，從而失去作用(yong)(yong)。在(zai)存放(fang)過程中，每隔(ge)3--6個(ge)月，要完成一個(ge)充電(dian)(dian)周期，做(zuo)一次電(dian)(dian)量校準。

鋰電池壽命一般有多長

鋰(li)電(dian)(dian)(dian)(dian)池一(yi)(yi)般(ban)能夠完(wan)全充(chong)(chong)(chong)(chong)放300-500個(ge)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)周期(qi)，超過這個(ge)次(ci)數(shu)，電(dian)(dian)(dian)(dian)池就(jiu)不(bu)能用(yong)(yong)了(le)(le)，當然，這只能作為參(can)考。鋰(li)電(dian)(dian)(dian)(dian)池壽(shou)命和(he)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)次(ci)數(shu)無關(guan)，與充(chong)(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)的周期(qi)有(you)關(guan)，也就(jiu)是(shi)從零電(dian)(dian)(dian)(dian)量(liang)(liang)充(chong)(chong)(chong)(chong)到(dao)滿(man)電(dian)(dian)(dian)(dian)量(liang)(liang)的次(ci)數(shu)。一(yi)(yi)個(ge)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)周期(qi)意味著電(dian)(dian)(dian)(dian)池的所(suo)有(you)電(dian)(dian)(dian)(dian)量(liang)(liang)由(you)滿(man)用(yong)(yong)到(dao)空(kong)，再由(you)空(kong)充(chong)(chong)(chong)(chong)到(dao)滿(man)的過程，這并不(bu)等同(tong)于充(chong)(chong)(chong)(chong)一(yi)(yi)次(ci)電(dian)(dian)(dian)(dian)。比(bi)如說，一(yi)(yi)塊(kuai)鋰(li)電(dian)(dian)(dian)(dian)在第一(yi)(yi)天只用(yong)(yong)了(le)(le)一(yi)(yi)半的電(dian)(dian)(dian)(dian)量(liang)(liang)，然后又為它(ta)充(chong)(chong)(chong)(chong)滿(man)電(dian)(dian)(dian)(dian)。如果第二(er)天還如此(ci)，即用(yong)(yong)一(yi)(yi)半就(jiu)充(chong)(chong)(chong)(chong)，總共兩(liang)(liang)次(ci)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)下來(lai)，這只能算(suan)作一(yi)(yi)個(ge)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)周期(qi)，而不(bu)是(shi)兩(liang)(liang)個(ge)。

在日常(chang)生活中，通(tong)常(chang)可(ke)能要經過(guo)好幾次(ci)充電(dian)(dian)(dian)(dian)才完(wan)成(cheng)一個周(zhou)期。每完(wan)成(cheng)一個充電(dian)(dian)(dian)(dian)周(zhou)期，電(dian)(dian)(dian)(dian)池容(rong)量就會(hui)減少(shao)一點。不過(guo)，這個電(dian)(dian)(dian)(dian)量減少(shao)幅度非(fei)常(chang)小，高(gao)品質的(de)電(dian)(dian)(dian)(dian)池充過(guo)多次(ci)周(zhou)期后(hou)，仍(reng)然會(hui)保留原始容(rong)量的(de)80%，很多鋰(li)(li)電(dian)(dian)(dian)(dian)供電(dian)(dian)(dian)(dian)產品在經過(guo)兩三(san)年后(hou)仍(reng)然照常(chang)使用。當然，鋰(li)(li)電(dian)(dian)(dian)(dian)壽命(ming)到了最終后(hou)仍(reng)是需要更(geng)換的(de)。
