鋰電池正確的充電方法

一、新電池充電

新電(dian)(dian)池一般要激(ji)活，電(dian)(dian)池放置一段時間(jian)后，會進(jin)入休眠狀(zhuang)態(tai)，此(ci)時容(rong)量低(di)于正(zheng)常(chang)值，使用時間(jian)亦隨(sui)之(zhi)縮短(duan)，因(yin)此(ci)需要激(ji)活。鋰電(dian)(dian)池激(ji)活方(fang)法(fa)非(fei)常(chang)簡單(dan)，只要經過3—5次(ci)正(zheng)常(chang)的充放電(dian)(dian)循環就可激(ji)活電(dian)(dian)池，恢復正(zheng)常(chang)容(rong)量。

二、舊電池充電

1、充電方法

舊電(dian)(dian)(dian)(dian)池(chi)(chi)是指已經充(chong)(chong)放電(dian)(dian)(dian)(dian)多次的電(dian)(dian)(dian)(dian)池(chi)(chi)，而(er)不(bu)是報廢的電(dian)(dian)(dian)(dian)池(chi)(chi)。鋰電(dian)(dian)(dian)(dian)池(chi)(chi)的壽命與充(chong)(chong)放電(dian)(dian)(dian)(dian)的次數(shu)無關，它沒有記憶效(xiao)應，不(bu)論(lun)你(ni)(ni)怎(zen)么充(chong)(chong)電(dian)(dian)(dian)(dian)，都不(bu)會(hui)影響(xiang)充(chong)(chong)電(dian)(dian)(dian)(dian)循環次數(shu)。因(yin)此不(bu)要把電(dian)(dian)(dian)(dian)池(chi)(chi)用到完全沒電(dian)(dian)(dian)(dian)才去(qu)充(chong)(chong)電(dian)(dian)(dian)(dian)，最(zui)好是當你(ni)(ni)能充(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)，就(jiu)盡量(liang)把電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)飽，充(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間以2-3小時(shi)以內為宜，當然(ran)你(ni)(ni)也不(bu)一定(ding)非要充(chong)(chong)滿。

2、充電電壓

鋰電(dian)(dian)池(chi)安全工作電(dian)(dian)壓范圍(wei)是(shi)2.8到4.2V，低于(yu)或高于(yu)這(zhe)個電(dian)(dian)壓范圍(wei)，電(dian)(dian)池(chi)中(zhong)的鋰離(li)子變(bian)得非常不(bu)穩定(ding)，甚至造成事故。為保證電(dian)(dian)池(chi)處于(yu)安全范圍(wei)，因此需要專門(men)的充(chong)電(dian)(dian)器(qi)。這(zhe)些充(chong)電(dian)(dian)器(qi)會自動根(gen)據(ju)電(dian)(dian)池(chi)當前狀態而調整充(chong)電(dian)(dian)方式(shi)。

3、充電工具

鋰電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)要用專用的充(chong)電(dian)(dian)(dian)(dian)(dian)器，它可以保障(zhang)充(chong)電(dian)(dian)(dian)(dian)(dian)的安全性。充(chong)電(dian)(dian)(dian)(dian)(dian)器工作時，以恒定(ding)(ding)的電(dian)(dian)(dian)(dian)(dian)流給電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)，隨著電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的升高(gao)，充(chong)電(dian)(dian)(dian)(dian)(dian)器同時提(ti)高(gao)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，以加(jia)快(kuai)充(chong)電(dian)(dian)(dian)(dian)(dian)速度(du)。當電(dian)(dian)(dian)(dian)(dian)池到達4.2V截止電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)時候(hou)，此時電(dian)(dian)(dian)(dian)(dian)池大約僅沖入70%左右的電(dian)(dian)(dian)(dian)(dian)量（并未飽滿）。此時充(chong)電(dian)(dian)(dian)(dian)(dian)器即(ji)以恒定(ding)(ding)的電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，逐漸(jian)變小的電(dian)(dian)(dian)(dian)(dian)流對電(dian)(dian)(dian)(dian)(dian)池繼續充(chong)電(dian)(dian)(dian)(dian)(dian)，當值至小于0.1A充(chong)電(dian)(dian)(dian)(dian)(dian)仍然檢測到電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)繼續升高(gao)時候(hou)才停止充(chong)電(dian)(dian)(dian)(dian)(dian)。

4、定期充電

長期不用的鋰(li)電(dian)池，應該以半電(dian)狀態(tai)，存(cun)放(fang)在陰(yin)涼偏(pian)干燥的地(di)方。滿電(dian)存(cun)放(fang)有危(wei)險(xian)，且電(dian)池會有損害(hai)，而無電(dian)存(cun)放(fang)，電(dian)池可能會被破壞，從而失(shi)去作用。在存(cun)放(fang)過程(cheng)中，每隔3--6個月，要完成一(yi)個充電(dian)周期，做一(yi)次(ci)電(dian)量校(xiao)準。

鋰電池壽命一般有多長

鋰電(dian)(dian)(dian)(dian)(dian)池一(yi)般能(neng)(neng)夠完全充(chong)(chong)(chong)(chong)放300-500個充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期，超過(guo)這個次數(shu)，電(dian)(dian)(dian)(dian)(dian)池就不能(neng)(neng)用了，當然，這只(zhi)能(neng)(neng)作為(wei)參考。鋰電(dian)(dian)(dian)(dian)(dian)池壽命和充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)次數(shu)無關，與充(chong)(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)的(de)周(zhou)(zhou)期有(you)(you)關，也就是(shi)從零(ling)電(dian)(dian)(dian)(dian)(dian)量充(chong)(chong)(chong)(chong)到(dao)滿電(dian)(dian)(dian)(dian)(dian)量的(de)次數(shu)。一(yi)個充(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(de)所有(you)(you)電(dian)(dian)(dian)(dian)(dian)量由(you)滿用到(dao)空，再由(you)空充(chong)(chong)(chong)(chong)到(dao)滿的(de)過(guo)程，這并不等同于充(chong)(chong)(chong)(chong)一(yi)次電(dian)(dian)(dian)(dian)(dian)。比如(ru)說(shuo)，一(yi)塊鋰電(dian)(dian)(dian)(dian)(dian)在(zai)第(di)一(yi)天只(zhi)用了一(yi)半(ban)的(de)電(dian)(dian)(dian)(dian)(dian)量，然后又為(wei)它充(chong)(chong)(chong)(chong)滿電(dian)(dian)(dian)(dian)(dian)。如(ru)果第(di)二天還如(ru)此，即用一(yi)半(ban)就充(chong)(chong)(chong)(chong)，總共兩次充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)下來，這只(zhi)能(neng)(neng)算(suan)作一(yi)個充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期，而不是(shi)兩個。

在日常(chang)(chang)(chang)生活中，通常(chang)(chang)(chang)可能要(yao)經(jing)過好幾次充(chong)電(dian)(dian)(dian)才完成一(yi)個周(zhou)期。每(mei)完成一(yi)個充(chong)電(dian)(dian)(dian)周(zhou)期，電(dian)(dian)(dian)池容(rong)量就(jiu)會減少一(yi)點。不過，這個電(dian)(dian)(dian)量減少幅(fu)度非(fei)常(chang)(chang)(chang)小，高品質的(de)電(dian)(dian)(dian)池充(chong)過多次周(zhou)期后，仍然(ran)會保留原(yuan)始容(rong)量的(de)80%，很多鋰(li)電(dian)(dian)(dian)供電(dian)(dian)(dian)產品在經(jing)過兩三年后仍然(ran)照(zhao)常(chang)(chang)(chang)使用。當然(ran)，鋰(li)電(dian)(dian)(dian)壽命到(dao)了最(zui)終后仍是需要(yao)更(geng)換的(de)。
