鋰電池正確的充電方法

一、新電池充電

新(xin)電(dian)池(chi)(chi)一(yi)般要(yao)激活，電(dian)池(chi)(chi)放(fang)置一(yi)段時間后，會進入休眠狀態，此時容量低于正(zheng)常值，使(shi)用時間亦隨之縮短，因此需要(yao)激活。鋰電(dian)池(chi)(chi)激活方法非(fei)常簡單(dan)，只(zhi)要(yao)經過3—5次(ci)正(zheng)常的充(chong)放(fang)電(dian)循環就可激活電(dian)池(chi)(chi)，恢復正(zheng)常容量。

二、舊電池充電

1、充電方法

舊(jiu)電(dian)池(chi)是指已(yi)經充(chong)(chong)(chong)放電(dian)多(duo)次(ci)的電(dian)池(chi)，而(er)不是報廢(fei)的電(dian)池(chi)。鋰電(dian)池(chi)的壽(shou)命與充(chong)(chong)(chong)放電(dian)的次(ci)數(shu)無關，它沒有記憶效應(ying)，不論你怎(zen)么充(chong)(chong)(chong)電(dian)，都不會影響充(chong)(chong)(chong)電(dian)循(xun)環次(ci)數(shu)。因此(ci)不要把電(dian)池(chi)用到完全沒電(dian)才去充(chong)(chong)(chong)電(dian)，最好是當(dang)你能充(chong)(chong)(chong)電(dian)時，就盡量把電(dian)池(chi)充(chong)(chong)(chong)飽(bao)，充(chong)(chong)(chong)電(dian)時間以2-3小(xiao)時以內為宜，當(dang)然你也(ye)不一(yi)定非要充(chong)(chong)(chong)滿。

2、充電電壓

鋰電(dian)(dian)池(chi)安(an)全工作電(dian)(dian)壓范(fan)圍是2.8到4.2V，低(di)于或高(gao)于這個(ge)電(dian)(dian)壓范(fan)圍，電(dian)(dian)池(chi)中的(de)鋰離子(zi)變得非常(chang)不(bu)穩定，甚至造(zao)成事故。為保證電(dian)(dian)池(chi)處于安(an)全范(fan)圍，因此需要專(zhuan)門的(de)充(chong)電(dian)(dian)器。這些充(chong)電(dian)(dian)器會自(zi)動根據電(dian)(dian)池(chi)當前狀態(tai)而調整充(chong)電(dian)(dian)方式。

3、充電工具

鋰電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)要用專(zhuan)用的充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器，它可以保障充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的安全性。充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器工作時(shi)，以恒(heng)(heng)定的電(dian)(dian)(dian)(dian)流(liu)給電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，隨著電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓的升高(gao)，充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器同時(shi)提(ti)高(gao)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓，以加快充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)速度。當(dang)電(dian)(dian)(dian)(dian)池(chi)到達4.2V截(jie)止電(dian)(dian)(dian)(dian)壓時(shi)候，此時(shi)電(dian)(dian)(dian)(dian)池(chi)大(da)約僅沖入(ru)70%左右(you)的電(dian)(dian)(dian)(dian)量（并(bing)未飽滿）。此時(shi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器即以恒(heng)(heng)定的電(dian)(dian)(dian)(dian)壓，逐漸變小的電(dian)(dian)(dian)(dian)流(liu)對(dui)電(dian)(dian)(dian)(dian)池(chi)繼續充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，當(dang)值至小于0.1A充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)仍(reng)然(ran)檢測到電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓繼續升高(gao)時(shi)候才停止充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。

4、定期充電

長期不用(yong)的(de)鋰電(dian)(dian)池(chi)，應該以(yi)半(ban)電(dian)(dian)狀(zhuang)態，存放(fang)在陰涼偏(pian)干燥的(de)地方。滿電(dian)(dian)存放(fang)有危險，且(qie)電(dian)(dian)池(chi)會有損害，而(er)(er)無(wu)電(dian)(dian)存放(fang)，電(dian)(dian)池(chi)可能會被(bei)破壞，從而(er)(er)失去作(zuo)用(yong)。在存放(fang)過程中，每隔3--6個(ge)(ge)月，要完成(cheng)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(li)電(dian)池一(yi)(yi)般能(neng)(neng)夠完全充放300-500個(ge)(ge)充電(dian)周期(qi)，超過這個(ge)(ge)次(ci)數，電(dian)池就(jiu)不(bu)能(neng)(neng)用了，當然，這只能(neng)(neng)作(zuo)為參考。鋰(li)電(dian)池壽命和充電(dian)次(ci)數無關(guan)，與(yu)充放電(dian)的(de)周期(qi)有關(guan)，也就(jiu)是從零電(dian)量(liang)(liang)(liang)充到滿電(dian)量(liang)(liang)(liang)的(de)次(ci)數。一(yi)(yi)個(ge)(ge)充電(dian)周期(qi)意味著電(dian)池的(de)所(suo)有電(dian)量(liang)(liang)(liang)由(you)滿用到空，再由(you)空充到滿的(de)過程，這并不(bu)等同于充一(yi)(yi)次(ci)電(dian)。比(bi)如說(shuo)，一(yi)(yi)塊鋰(li)電(dian)在第一(yi)(yi)天只用了一(yi)(yi)半的(de)電(dian)量(liang)(liang)(liang)，然后又為它充滿電(dian)。如果第二天還如此，即用一(yi)(yi)半就(jiu)充，總共兩(liang)次(ci)充電(dian)下(xia)來(lai)，這只能(neng)(neng)算作(zuo)一(yi)(yi)個(ge)(ge)充電(dian)周期(qi)，而不(bu)是兩(liang)個(ge)(ge)。

在(zai)日常(chang)生活(huo)中，通常(chang)可能要(yao)經過好(hao)幾(ji)次充(chong)電才完(wan)成一(yi)個周期。每完(wan)成一(yi)個充(chong)電周期，電池容量就會(hui)減少(shao)一(yi)點(dian)。不過，這個電量減少(shao)幅度(du)非常(chang)小(xiao)，高品質的電池充(chong)過多次周期后(hou)，仍然(ran)會(hui)保留(liu)原(yuan)始容量的80%，很多鋰(li)電供電產品在(zai)經過兩三(san)年(nian)后(hou)仍然(ran)照常(chang)使用(yong)。當然(ran)，鋰(li)電壽命到(dao)了最終(zhong)后(hou)仍是需要(yao)更換的。
