鋰電池正確的充電方法

一、新電池充電

新電池(chi)(chi)一(yi)般(ban)要(yao)激活，電池(chi)(chi)放置一(yi)段(duan)時(shi)(shi)間后，會(hui)進(jin)入(ru)休眠狀態(tai)，此(ci)時(shi)(shi)容(rong)量低于正(zheng)常(chang)(chang)值，使(shi)用時(shi)(shi)間亦隨之縮短，因此(ci)需要(yao)激活。鋰電池(chi)(chi)激活方法非常(chang)(chang)簡單(dan)，只(zhi)要(yao)經過(guo)3—5次正(zheng)常(chang)(chang)的(de)充(chong)放電循環就可激活電池(chi)(chi)，恢復(fu)正(zheng)常(chang)(chang)容(rong)量。

二、舊電池充電

1、充電方法

舊電(dian)(dian)(dian)池是指已經(jing)充(chong)放電(dian)(dian)(dian)多次(ci)的電(dian)(dian)(dian)池，而不是報廢的電(dian)(dian)(dian)池。鋰電(dian)(dian)(dian)池的壽(shou)命與(yu)充(chong)放電(dian)(dian)(dian)的次(ci)數無關，它沒有記憶效應，不論你怎(zen)么充(chong)電(dian)(dian)(dian)，都不會影(ying)響充(chong)電(dian)(dian)(dian)循環次(ci)數。因此不要(yao)把電(dian)(dian)(dian)池用到完全沒電(dian)(dian)(dian)才(cai)去(qu)充(chong)電(dian)(dian)(dian)，最好是當你能充(chong)電(dian)(dian)(dian)時(shi)，就盡量把電(dian)(dian)(dian)池充(chong)飽，充(chong)電(dian)(dian)(dian)時(shi)間以2-3小時(shi)以內為宜，當然你也不一定非要(yao)充(chong)滿。

2、充電電壓

鋰電(dian)(dian)池(chi)安全(quan)工作(zuo)電(dian)(dian)壓范(fan)(fan)圍(wei)是2.8到4.2V，低于或高(gao)于這(zhe)個(ge)電(dian)(dian)壓范(fan)(fan)圍(wei)，電(dian)(dian)池(chi)中的鋰離子變得非常不(bu)穩定(ding)，甚至造(zao)成事故(gu)。為保證電(dian)(dian)池(chi)處(chu)于安全(quan)范(fan)(fan)圍(wei)，因此需要專門的充(chong)(chong)電(dian)(dian)器。這(zhe)些(xie)充(chong)(chong)電(dian)(dian)器會(hui)自(zi)動根據電(dian)(dian)池(chi)當(dang)前狀(zhuang)態而調整充(chong)(chong)電(dian)(dian)方式(shi)。

3、充電工具

鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)要用專用的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，它(ta)可以保障充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)安全(quan)性。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)工作時(shi)(shi)(shi)，以恒定的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，隨(sui)著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)升高，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)同(tong)時(shi)(shi)(shi)提高充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，以加(jia)快充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度。當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池到達4.2V截止(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓時(shi)(shi)(shi)候，此時(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池大約(yue)僅沖入70%左右的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量（并未飽滿(man)）。此時(shi)(shi)(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)即(ji)以恒定的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，逐漸變小的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池繼續充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當(dang)值至(zhi)小于0.1A充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)仍然檢測到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓繼續升高時(shi)(shi)(shi)候才(cai)停止(zhi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

4、定期充電

長期不(bu)用的(de)鋰電(dian)(dian)(dian)(dian)池(chi)，應該以半電(dian)(dian)(dian)(dian)狀態，存(cun)放(fang)在(zai)陰(yin)涼偏(pian)干燥的(de)地方。滿(man)電(dian)(dian)(dian)(dian)存(cun)放(fang)有危險，且電(dian)(dian)(dian)(dian)池(chi)會(hui)有損害，而(er)無電(dian)(dian)(dian)(dian)存(cun)放(fang)，電(dian)(dian)(dian)(dian)池(chi)可能會(hui)被破壞，從而(er)失去作(zuo)用。在(zai)存(cun)放(fang)過(guo)程(cheng)中(zhong)，每隔(ge)3--6個月，要完成一(yi)個充電(dian)(dian)(dian)(dian)周期，做一(yi)次電(dian)(dian)(dian)(dian)量校準。

鋰電池壽命一般有多長

鋰電(dian)(dian)(dian)(dian)(dian)(dian)池一(yi)般能(neng)夠完全充(chong)(chong)(chong)放300-500個(ge)(ge)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期(qi)，超過(guo)這個(ge)(ge)次(ci)數(shu)(shu)(shu)，電(dian)(dian)(dian)(dian)(dian)(dian)池就不能(neng)用了(le)，當然(ran)(ran)，這只(zhi)能(neng)作為參考。鋰電(dian)(dian)(dian)(dian)(dian)(dian)池壽命和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)次(ci)數(shu)(shu)(shu)無關(guan)，與充(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)的周(zhou)(zhou)期(qi)有關(guan)，也就是從零電(dian)(dian)(dian)(dian)(dian)(dian)量充(chong)(chong)(chong)到滿電(dian)(dian)(dian)(dian)(dian)(dian)量的次(ci)數(shu)(shu)(shu)。一(yi)個(ge)(ge)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期(qi)意味著電(dian)(dian)(dian)(dian)(dian)(dian)池的所有電(dian)(dian)(dian)(dian)(dian)(dian)量由滿用到空，再由空充(chong)(chong)(chong)到滿的過(guo)程，這并不等同(tong)于充(chong)(chong)(chong)一(yi)次(ci)電(dian)(dian)(dian)(dian)(dian)(dian)。比如說，一(yi)塊鋰電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)第一(yi)天(tian)只(zhi)用了(le)一(yi)半的電(dian)(dian)(dian)(dian)(dian)(dian)量，然(ran)(ran)后又為它充(chong)(chong)(chong)滿電(dian)(dian)(dian)(dian)(dian)(dian)。如果(guo)第二(er)天(tian)還如此，即(ji)用一(yi)半就充(chong)(chong)(chong)，總(zong)共(gong)兩(liang)次(ci)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)下來(lai)，這只(zhi)能(neng)算作一(yi)個(ge)(ge)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期(qi)，而不是兩(liang)個(ge)(ge)。

在日常(chang)生活中(zhong)，通常(chang)可(ke)能(neng)要經過好(hao)幾次(ci)充電(dian)才完(wan)成(cheng)一個周期(qi)。每(mei)完(wan)成(cheng)一個充電(dian)周期(qi)，電(dian)池容量(liang)就會(hui)減少一點(dian)。不過，這個電(dian)量(liang)減少幅度非常(chang)小，高品質的(de)(de)電(dian)池充過多次(ci)周期(qi)后(hou)，仍然(ran)會(hui)保留原始容量(liang)的(de)(de)80%，很多鋰電(dian)供電(dian)產品在經過兩三年后(hou)仍然(ran)照常(chang)使用(yong)。當然(ran)，鋰電(dian)壽命到了最終后(hou)仍是需要更(geng)換的(de)(de)。
