鋰電池正確的充電方法

一、新電池充電

新(xin)電(dian)池一(yi)般(ban)要激(ji)(ji)活，電(dian)池放(fang)置(zhi)一(yi)段時(shi)間后，會(hui)進入休眠狀態(tai)，此(ci)時(shi)容(rong)量(liang)低于正常(chang)(chang)值，使(shi)用(yong)時(shi)間亦隨之縮短，因此(ci)需(xu)要激(ji)(ji)活。鋰(li)電(dian)池激(ji)(ji)活方法非(fei)常(chang)(chang)簡單(dan)，只要經過3—5次正常(chang)(chang)的充放(fang)電(dian)循環就可激(ji)(ji)活電(dian)池，恢(hui)復正常(chang)(chang)容(rong)量(liang)。

二、舊電池充電

1、充電方法

舊電(dian)(dian)(dian)池是(shi)(shi)指已經充(chong)放電(dian)(dian)(dian)多次的(de)電(dian)(dian)(dian)池，而不(bu)(bu)是(shi)(shi)報廢的(de)電(dian)(dian)(dian)池。鋰電(dian)(dian)(dian)池的(de)壽(shou)命與充(chong)放電(dian)(dian)(dian)的(de)次數無關，它(ta)沒有記憶效應(ying)，不(bu)(bu)論(lun)你(ni)怎么充(chong)電(dian)(dian)(dian)，都不(bu)(bu)會影(ying)響(xiang)充(chong)電(dian)(dian)(dian)循環次數。因此不(bu)(bu)要把(ba)電(dian)(dian)(dian)池用(yong)到完全沒電(dian)(dian)(dian)才去充(chong)電(dian)(dian)(dian)，最好(hao)是(shi)(shi)當你(ni)能充(chong)電(dian)(dian)(dian)時，就盡量(liang)把(ba)電(dian)(dian)(dian)池充(chong)飽，充(chong)電(dian)(dian)(dian)時間以(yi)2-3小時以(yi)內為宜，當然你(ni)也不(bu)(bu)一定非要充(chong)滿。

2、充電電壓

鋰電(dian)(dian)池安(an)全(quan)工作電(dian)(dian)壓范(fan)(fan)圍(wei)是2.8到4.2V，低于(yu)或高于(yu)這個電(dian)(dian)壓范(fan)(fan)圍(wei)，電(dian)(dian)池中的(de)鋰離子變得非常不穩定，甚(shen)至造成事故。為保(bao)證(zheng)電(dian)(dian)池處于(yu)安(an)全(quan)范(fan)(fan)圍(wei)，因此需要專門的(de)充電(dian)(dian)器。這些充電(dian)(dian)器會(hui)自動根據(ju)電(dian)(dian)池當前狀態而調整充電(dian)(dian)方式。

3、充電工具

鋰電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)要用專用的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)器，它可(ke)以保障(zhang)充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)(de)安全性。充(chong)(chong)(chong)電(dian)(dian)(dian)器工作時，以恒定的(de)(de)電(dian)(dian)(dian)流給電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)，隨著電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)的(de)(de)升(sheng)高(gao)(gao)，充(chong)(chong)(chong)電(dian)(dian)(dian)器同時提高(gao)(gao)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)，以加快充(chong)(chong)(chong)電(dian)(dian)(dian)速度(du)。當電(dian)(dian)(dian)池到達4.2V截(jie)止電(dian)(dian)(dian)壓(ya)時候，此時電(dian)(dian)(dian)池大約僅沖入70%左右的(de)(de)電(dian)(dian)(dian)量（并未飽滿）。此時充(chong)(chong)(chong)電(dian)(dian)(dian)器即以恒定的(de)(de)電(dian)(dian)(dian)壓(ya)，逐漸(jian)變小(xiao)(xiao)的(de)(de)電(dian)(dian)(dian)流對電(dian)(dian)(dian)池繼續充(chong)(chong)(chong)電(dian)(dian)(dian)，當值至小(xiao)(xiao)于0.1A充(chong)(chong)(chong)電(dian)(dian)(dian)仍然檢測(ce)到電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)繼續升(sheng)高(gao)(gao)時候才停止充(chong)(chong)(chong)電(dian)(dian)(dian)。

4、定期充電

長(chang)期(qi)不用的鋰電(dian)池(chi)，應該以半電(dian)狀態，存(cun)放(fang)(fang)(fang)在(zai)陰涼偏干燥的地方。滿電(dian)存(cun)放(fang)(fang)(fang)有危險，且電(dian)池(chi)會有損(sun)害(hai)，而無電(dian)存(cun)放(fang)(fang)(fang)，電(dian)池(chi)可能會被破(po)壞，從而失去(qu)作(zuo)用。在(zai)存(cun)放(fang)(fang)(fang)過程中(zhong)，每隔3--6個月，要完成一(yi)個充電(dian)周期(qi)，做一(yi)次電(dian)量校(xiao)準。

鋰電池壽命一般有多長

鋰電(dian)(dian)池一(yi)般能(neng)(neng)夠完全充(chong)(chong)(chong)(chong)放(fang)300-500個(ge)(ge)(ge)充(chong)(chong)(chong)(chong)電(dian)(dian)周期，超過這(zhe)個(ge)(ge)(ge)次(ci)(ci)數，電(dian)(dian)池就(jiu)(jiu)不能(neng)(neng)用了(le)，當然，這(zhe)只(zhi)能(neng)(neng)作(zuo)為參考。鋰電(dian)(dian)池壽命(ming)和(he)充(chong)(chong)(chong)(chong)電(dian)(dian)次(ci)(ci)數無關，與充(chong)(chong)(chong)(chong)放(fang)電(dian)(dian)的(de)(de)周期有(you)關，也就(jiu)(jiu)是從零電(dian)(dian)量(liang)充(chong)(chong)(chong)(chong)到滿電(dian)(dian)量(liang)的(de)(de)次(ci)(ci)數。一(yi)個(ge)(ge)(ge)充(chong)(chong)(chong)(chong)電(dian)(dian)周期意味著電(dian)(dian)池的(de)(de)所(suo)有(you)電(dian)(dian)量(liang)由(you)滿用到空，再(zai)由(you)空充(chong)(chong)(chong)(chong)到滿的(de)(de)過程，這(zhe)并不等同于(yu)充(chong)(chong)(chong)(chong)一(yi)次(ci)(ci)電(dian)(dian)。比如(ru)說，一(yi)塊(kuai)鋰電(dian)(dian)在第一(yi)天(tian)只(zhi)用了(le)一(yi)半的(de)(de)電(dian)(dian)量(liang)，然后(hou)又為它(ta)充(chong)(chong)(chong)(chong)滿電(dian)(dian)。如(ru)果(guo)第二(er)天(tian)還如(ru)此(ci)，即(ji)用一(yi)半就(jiu)(jiu)充(chong)(chong)(chong)(chong)，總共(gong)兩次(ci)(ci)充(chong)(chong)(chong)(chong)電(dian)(dian)下(xia)來(lai)，這(zhe)只(zhi)能(neng)(neng)算(suan)作(zuo)一(yi)個(ge)(ge)(ge)充(chong)(chong)(chong)(chong)電(dian)(dian)周期，而不是兩個(ge)(ge)(ge)。

在日常生(sheng)活(huo)中(zhong)，通常可能要(yao)經過(guo)(guo)(guo)好(hao)幾(ji)次(ci)充(chong)電(dian)(dian)才完(wan)成一(yi)(yi)個周(zhou)期。每完(wan)成一(yi)(yi)個充(chong)電(dian)(dian)周(zhou)期，電(dian)(dian)池容(rong)量(liang)就(jiu)會減少(shao)一(yi)(yi)點。不過(guo)(guo)(guo)，這個電(dian)(dian)量(liang)減少(shao)幅(fu)度非常小，高(gao)品質的電(dian)(dian)池充(chong)過(guo)(guo)(guo)多(duo)次(ci)周(zhou)期后，仍然(ran)會保留原始容(rong)量(liang)的80%，很多(duo)鋰電(dian)(dian)供電(dian)(dian)產品在經過(guo)(guo)(guo)兩(liang)三年后仍然(ran)照(zhao)常使用(yong)。當然(ran)，鋰電(dian)(dian)壽命到(dao)了最終(zhong)后仍是需要(yao)更換(huan)的。
