在使用手機時，值得大家應注意的是鋰電池，電(dian)(dian)池放置一段時間后則進入(ru)休眠(mian)狀態，此時容(rong)量低于(yu)正常(chang)(chang)值，使用(yong)時間亦隨之縮短。但鋰電(dian)(dian)池很容(rong)易激活，只要經過(guo)3―5次正常(chang)(chang)的(de)充(chong)放電(dian)(dian)循環就可激活電(dian)(dian)池，恢復正常(chang)(chang)容(rong)量。由于(yu)鋰電(dian)(dian)池本身的(de)特性，決定了它幾乎沒(mei)有記憶效應。因此用(yong)戶手機(ji)中的(de)新鋰電(dian)(dian)池在激活過(guo)程中，是不(bu)需要特別的(de)方法(fa)和設備的(de)。不(bu)僅(jin)理(li)論上是如此，從(cong)我自己(ji)的(de)實(shi)踐(jian)來看(kan)，從(cong)一開始就采用(yong)標(biao)準方法(fa)充(chong)電(dian)(dian)這種“自然(ran)激活”方式(shi)是最好的(de)。

     對于鋰電池的“激活”問題，眾多的說法是：充電時間一定要超過12小時，反復做三次，以便激活電池。這種“前三次充電要充12小時以上”的說法，明顯是從鎳電池（如鎳鎘和鎳氫）延續下來的說法。所以這種說法，可以說一開始就是誤傳。鋰電池和鎳電池的充放電特性有非常大的區別，而且可以非常明確的告訴大家，我所查閱過的所有嚴肅的正式技術資料都強調過充和過放電會對鋰電池、特別是液體鋰離子電池造(zao)成巨大的(de)傷害。因(yin)而充(chong)電(dian)(dian)最好(hao)按(an)照標準時(shi)間和標準方(fang)法充(chong)電(dian)(dian)，特別是不(bu)要進行超過12個小(xiao)時(shi)的(de)超長(chang)充(chong)電(dian)(dian)。通常，手機說明書(shu)上介(jie)紹的(de)充(chong)電(dian)(dian)方(fang)法，就是適合(he)該手機的(de)標準充(chong)電(dian)(dian)方(fang)法。

    此外，鋰電(dian)(dian)池(chi)的手機或充(chong)(chong)電(dian)(dian)器(qi)在(zai)電(dian)(dian)池(chi)充(chong)(chong)滿(man)后(hou)(hou)都會(hui)自動停充(chong)(chong)，并不(bu)存在(zai)鎳(nie)電(dian)(dian)充(chong)(chong)電(dian)(dian)器(qi)所謂的持續10幾小(xiao)時(shi)的“涓流”充(chong)(chong)電(dian)(dian)。也(ye)(ye)就是(shi)說，如果你(ni)的鋰電(dian)(dian)池(chi)在(zai)充(chong)(chong)滿(man)后(hou)(hou)，放在(zai)充(chong)(chong)電(dian)(dian)器(qi)上也(ye)(ye)是(shi)白充(chong)(chong)。而我(wo)們誰都無(wu)法保證(zheng)電(dian)(dian)池(chi)的充(chong)(chong)放電(dian)(dian)保護電(dian)(dian)路的特性(xing)永不(bu)變化和質量的萬無(wu)一失(shi)，所以你(ni)的電(dian)(dian)池(chi)將長期處在(zai)危(wei)險(xian)的邊緣徘(pai)徊。這也(ye)(ye)是(shi)我(wo)們反對長充(chong)(chong)電(dian)(dian)的另(ling)一個理(li)由。

1、此外(wai)在(zai)對某些手機上，充電(dian)(dian)超過(guo)一定的(de)(de)時間(jian)(jian)后，如果不(bu)去取下充電(dian)(dian)器(qi)，這(zhe)時系統不(bu)僅不(bu)停止充電(dian)(dian)，還將開始放(fang)電(dian)(dian)-充電(dian)(dian)循(xun)環(huan)。也許這(zhe)種做法(fa)的(de)(de)廠商自有其目(mu)的(de)(de)，但顯然對電(dian)(dian)池和手機/充電(dian)(dian)器(qi)的(de)(de)壽命而言(yan)是(shi)不(bu)利的(de)(de)。同(tong)(tong)時，長充電(dian)(dian)需要很(hen)(hen)長的(de)(de)時間(jian)(jian)，往往需要在(zai)夜(ye)間(jian)(jian)進(jin)行，而以我國(guo)電(dian)(dian)網的(de)(de)情況看(kan)，許多地方夜(ye)間(jian)(jian)的(de)(de)電(dian)(dian)壓都(dou)比(bi)較高(gao)，而且波動較大(da)。前面(mian)已(yi)經說(shuo)過(guo)，鋰(li)電(dian)(dian)池是(shi)很(hen)(hen)嬌貴的(de)(de)，它比(bi)鎳電(dian)(dian)在(zai)充放(fang)電(dian)(dian)方面(mian)耐波動的(de)(de)能力差得多，于是(shi)這(zhe)又帶來附加的(de)(de)危(wei)險。 此外(wai)，不(bu)可忽視的(de)(de)另外(wai)一個方面(mian)就是(shi)鋰(li)電(dian)(dian)池同(tong)(tong)樣(yang)也不(bu)適(shi)合過(guo)放(fang)電(dian)(dian)，過(guo)放(fang)電(dian)(dian)對鋰(li)電(dian)(dian)池同(tong)(tong)樣(yang)也很(hen)(hen)不(bu)利。

2、正(zheng)常使用(yong)中應(ying)該何時開始充電

在我們的(de)論壇上，經常可(ke)以見到這種說(shuo)法，因為充(chong)放電(dian)(dian)(dian)的(de)次數(shu)是(shi)有限的(de)，所以應該(gai)將手機電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)盡(jin)可(ke)能(neng)用光再(zai)充(chong)電(dian)(dian)(dian)。但是(shi)我找到一個關于鋰離子電(dian)(dian)(dian)池(chi)充(chong)放電(dian)(dian)(dian)循環的(de)實驗表(biao)，關于循環壽命的(de)數(shu)據列出(chu)如下：

循(xun)環壽命 (10%DOD):>1000次(ci)

循環(huan)壽命 (100%DOD):>200次

其中(zhong)(zhong)(zhong)DOD是放電(dian)(dian)(dian)(dian)(dian)深度的(de)(de)(de)(de)英文縮寫。從(cong)表(biao)中(zhong)(zhong)(zhong)可(ke)見，可(ke)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)次(ci)數和放電(dian)(dian)(dian)(dian)(dian)深度有(you)關(guan)，10%DOD時的(de)(de)(de)(de)循環(huan)壽(shou)(shou)命要(yao)比100%DOD的(de)(de)(de)(de)要(yao)長(chang)很多。當(dang)然(ran)如(ru)果折合到(dao)實際充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)相對總容量(liang)(liang)(liang)：10%*1000=100，100%*200=200，后(hou)(hou)者(zhe)的(de)(de)(de)(de)完(wan)全充(chong)(chong)(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)還是要(yao)比較好(hao)一(yi)(yi)些，但前面網友的(de)(de)(de)(de)那個(ge)(ge)說(shuo)法要(yao)做(zuo)(zuo)一(yi)(yi)些修正(zheng)(zheng)：在(zai)(zai)正(zheng)(zheng)常情(qing)況(kuang)下，你(ni)(ni)(ni)應該有(you)保留(liu)地按照電(dian)(dian)(dian)(dian)(dian)池剩(sheng)(sheng)余(yu)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)用完(wan)再充(chong)(chong)(chong)(chong)(chong)的(de)(de)(de)(de)原則充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，但假如(ru)你(ni)(ni)(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池在(zai)(zai)你(ni)(ni)(ni)預計第2天不(bu)(bu)可(ke)能堅持(chi)整個(ge)(ge)白天的(de)(de)(de)(de)時候(hou)，就應該及時開(kai)始充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，當(dang)然(ran)你(ni)(ni)(ni)如(ru)果愿意(yi)背著充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器到(dao)辦公室又當(dang)別論(lun)。而你(ni)(ni)(ni)需要(yao)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)以(yi)應付預計即將(jiang)到(dao)來(lai)的(de)(de)(de)(de)會導致(zhi)通訊繁忙的(de)(de)(de)(de)重要(yao)事件的(de)(de)(de)(de)時候(hou)，即使(shi)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)池尚有(you)很多余(yu)電(dian)(dian)(dian)(dian)(dian)時，那么你(ni)(ni)(ni)也(ye)(ye)只管(guan)提前充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，因為(wei)你(ni)(ni)(ni)并沒有(you)真正(zheng)(zheng)損失“1”次(ci)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)循環(huan)壽(shou)(shou)命，也(ye)(ye)就是“0.x”次(ci)而已，而且(qie)往往這個(ge)(ge)x會很小。 電(dian)(dian)(dian)(dian)(dian)池剩(sheng)(sheng)余(yu)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)用完(wan)再充(chong)(chong)(chong)(chong)(chong)的(de)(de)(de)(de)原則并不(bu)(bu)是要(yao)你(ni)(ni)(ni)走向極端。和長(chang)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)一(yi)(yi)樣流(liu)傳(chuan)甚廣(guang)的(de)(de)(de)(de)一(yi)(yi)個(ge)(ge)說(shuo)法，就是“盡量(liang)(liang)(liang)把手(shou)機電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)用完(wan)，最好(hao)用到(dao)自動關(guan)機”。這種做(zuo)(zuo)法其實只是鎳電(dian)(dian)(dian)(dian)(dian)池上的(de)(de)(de)(de)做(zuo)(zuo)法，目的(de)(de)(de)(de)是避免記憶(yi)效應發生(sheng)，不(bu)(bu)幸(xing)的(de)(de)(de)(de)是它也(ye)(ye)在(zai)(zai)鋰電(dian)(dian)(dian)(dian)(dian)池上流(liu)傳(chuan)之(zhi)今。曾經有(you)人因為(wei)手(shou)機電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)過低的(de)(de)(de)(de)警(jing)告出現后(hou)(hou)，仍然(ran)不(bu)(bu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)繼續(xu)使(shi)用一(yi)(yi)直用到(dao)自動關(guan)機的(de)(de)(de)(de)例(li)子。結果這個(ge)(ge)例(li)子中(zhong)(zhong)(zhong)的(de)(de)(de)(de)手(shou)機在(zai)(zai)后(hou)(hou)來(lai)的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)及開(kai)機中(zhong)(zhong)(zhong)均(jun)無反應，不(bu)(bu)得不(bu)(bu)送客服檢修。這其實就是由(you)于電(dian)(dian)(dian)(dian)(dian)池因過度放電(dian)(dian)(dian)(dian)(dian)而導致(zhi)電(dian)(dian)(dian)(dian)(dian)壓過低，以(yi)至于不(bu)(bu)具備正(zheng)(zheng)常的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)和開(kai)機條件造成(cheng)的(de)(de)(de)(de)。

3、對鋰(li)電池手機的(de)正(zheng)確(que)做法

歸結起來，我對鋰(li)電池手機在(zai)使用中的充放(fang)電問(wen)題最重要(yao)的提示(shi)是：

1、按照標準的時間和(he)程序充電，即使是前(qian)三次也要如此進行；

2、當出現手機電量過低提示時，應該盡(jin)量及(ji)時開(kai)始充電；

3、鋰電池(chi)的激(ji)活并不需(xu)要特別的方(fang)法，在手機(ji)正常使用中鋰電池(chi)會自然激(ji)活。如(ru)果(guo)你執意要用流傳的“前三(san)次(ci)12小時長充(chong)電激(ji)活”方(fang)法，實際(ji)上也(ye)不會有(you)效果(guo)。

因此，所(suo)有(you)追求(qiu)12小時(shi)超長充電和把鋰電池(chi)手機(ji)用到(dao)自動關機(ji)的做法，都是錯誤(wu)的。如果你以(yi)前是按照錯誤(wu)的說法做的，請你及時(shi)改正(zheng)，也許為(wei)時(shi)還不(bu)晚。

    當然，在(zai)(zai)手機及充(chong)電(dian)(dian)器(qi)自身保(bao)護和控制電(dian)(dian)路質量(liang)良(liang)好的(de)(de)(de)情況下(xia)(xia)，對(dui)鋰電(dian)(dian)池的(de)(de)(de)保(bao)護還是(shi)有相當保(bao)證的(de)(de)(de)。所以對(dui)充(chong)電(dian)(dian)規則的(de)(de)(de)理解才是(shi)重點，在(zai)(zai)某(mou)些情況下(xia)(xia)也(ye)是(shi)可以做出某(mou)種讓(rang)步的(de)(de)(de)。比如你(ni)發現手機在(zai)(zai)你(ni)夜晚睡覺前必須充(chong)電(dian)(dian)的(de)(de)(de)話，你(ni)也(ye)可以在(zai)(zai)睡前開始充(chong)電(dian)(dian)。問(wen)題的(de)(de)(de)關(guan)鍵在(zai)(zai)于，你(ni)應(ying)該知道正確的(de)(de)(de)做法是(shi)什(shen)么，并且(qie)不要刻意按照錯誤的(de)(de)(de)說法去做。

希望(wang)大家努力(li)掌(zhang)握(wo)關于鋰電(dian)池(chi)的(de)知識和(he)學會(hui)正(zheng)確(que)使用鋰電(dian)池(chi)的(de)科(ke)學方法，早日(ri)在鋰電(dian)池(chi)的(de)手機上與(yu)流傳已(yi)久(jiu)的(de)錯誤說法和(he)做(zuo)法告別。
