在使用手機時，值得大家應注意的是鋰電池，電(dian)(dian)(dian)池(chi)放(fang)置一(yi)段時間后則(ze)進入(ru)休眠狀態，此(ci)時容(rong)量低于(yu)正(zheng)常(chang)(chang)值，使用時間亦隨(sui)之縮(suo)短。但鋰電(dian)(dian)(dian)池(chi)很容(rong)易激(ji)活(huo)，只要經過3―5次正(zheng)常(chang)(chang)的充放(fang)電(dian)(dian)(dian)循環就可激(ji)活(huo)電(dian)(dian)(dian)池(chi)，恢復正(zheng)常(chang)(chang)容(rong)量。由于(yu)鋰電(dian)(dian)(dian)池(chi)本(ben)身的特性，決定了它(ta)幾(ji)乎(hu)沒有記憶(yi)效(xiao)應。因此(ci)用戶(hu)手機中的新鋰電(dian)(dian)(dian)池(chi)在(zai)激(ji)活(huo)過程中，是不(bu)需要特別的方法和設備的。不(bu)僅理(li)論上是如此(ci)，從我自(zi)己的實踐來看，從一(yi)開始(shi)就采用標準方法充電(dian)(dian)(dian)這種“自(zi)然激(ji)活(huo)”方式(shi)是最好(hao)的。

     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成巨大的傷害。因(yin)而充電(dian)最(zui)好按照標準(zhun)時(shi)間和標準(zhun)方(fang)法充電(dian)，特別是不要進行超過12個小時(shi)的超長充電(dian)。通常，手(shou)(shou)機說明書上介(jie)紹(shao)的充電(dian)方(fang)法，就是適合該(gai)手(shou)(shou)機的標準(zhun)充電(dian)方(fang)法。

    此外，鋰電(dian)(dian)池(chi)(chi)(chi)的(de)(de)手機或充(chong)(chong)電(dian)(dian)器在電(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)滿后都(dou)會自動(dong)停充(chong)(chong)，并不存在鎳電(dian)(dian)充(chong)(chong)電(dian)(dian)器所謂的(de)(de)持(chi)續10幾小時的(de)(de)“涓(juan)流”充(chong)(chong)電(dian)(dian)。也(ye)就是說(shuo)，如果你的(de)(de)鋰電(dian)(dian)池(chi)(chi)(chi)在充(chong)(chong)滿后，放在充(chong)(chong)電(dian)(dian)器上也(ye)是白充(chong)(chong)。而我們誰(shui)都(dou)無(wu)法保(bao)證電(dian)(dian)池(chi)(chi)(chi)的(de)(de)充(chong)(chong)放電(dian)(dian)保(bao)護電(dian)(dian)路的(de)(de)特性永不變化和質量的(de)(de)萬無(wu)一(yi)失，所以你的(de)(de)電(dian)(dian)池(chi)(chi)(chi)將長期(qi)處在危險的(de)(de)邊緣徘徊(huai)。這也(ye)是我們反對長充(chong)(chong)電(dian)(dian)的(de)(de)另一(yi)個理由。

1、此外(wai)在對(dui)某些手機上，充(chong)(chong)電(dian)(dian)(dian)超過一(yi)定的(de)(de)(de)(de)時間(jian)后，如果不(bu)去取(qu)下充(chong)(chong)電(dian)(dian)(dian)器，這時系統不(bu)僅(jin)不(bu)停止充(chong)(chong)電(dian)(dian)(dian)，還將開(kai)始放電(dian)(dian)(dian)-充(chong)(chong)電(dian)(dian)(dian)循環。也(ye)許(xu)這種做法的(de)(de)(de)(de)廠商(shang)自有(you)其目的(de)(de)(de)(de)，但顯然對(dui)電(dian)(dian)(dian)池和手機/充(chong)(chong)電(dian)(dian)(dian)器的(de)(de)(de)(de)壽命而(er)言是(shi)(shi)不(bu)利(li)的(de)(de)(de)(de)。同時，長充(chong)(chong)電(dian)(dian)(dian)需要很長的(de)(de)(de)(de)時間(jian)，往往需要在夜(ye)間(jian)進行，而(er)以(yi)我(wo)國(guo)電(dian)(dian)(dian)網的(de)(de)(de)(de)情況看，許(xu)多(duo)(duo)地方(fang)夜(ye)間(jian)的(de)(de)(de)(de)電(dian)(dian)(dian)壓都比較高，而(er)且波動較大。前面已(yi)經(jing)說過，鋰電(dian)(dian)(dian)池是(shi)(shi)很嬌(jiao)貴的(de)(de)(de)(de)，它比鎳電(dian)(dian)(dian)在充(chong)(chong)放電(dian)(dian)(dian)方(fang)面耐波動的(de)(de)(de)(de)能力差得多(duo)(duo)，于是(shi)(shi)這又帶來(lai)附加的(de)(de)(de)(de)危險。 此外(wai)，不(bu)可(ke)忽視(shi)的(de)(de)(de)(de)另外(wai)一(yi)個方(fang)面就是(shi)(shi)鋰電(dian)(dian)(dian)池同樣(yang)也(ye)不(bu)適合過放電(dian)(dian)(dian)，過放電(dian)(dian)(dian)對(dui)鋰電(dian)(dian)(dian)池同樣(yang)也(ye)很不(bu)利(li)。

2、正(zheng)常(chang)使用中應該何時開始充電(dian)

在我們的論壇上，經常可以見到(dao)這種說法，因為充(chong)(chong)放(fang)(fang)電(dian)的次(ci)數是有(you)限的，所以應該將手(shou)機電(dian)池的電(dian)盡可能用(yong)光(guang)再(zai)充(chong)(chong)電(dian)。但是我找(zhao)到(dao)一個(ge)關(guan)于鋰離子電(dian)池充(chong)(chong)放(fang)(fang)電(dian)循環的實驗表(biao)，關(guan)于循環壽命的數據列出如下：

循環壽命 (10%DOD):>1000次

循(xun)環壽(shou)命(ming) (100%DOD):>200次

其(qi)中(zhong)(zhong)DOD是(shi)(shi)(shi)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)深(shen)度(du)(du)的(de)(de)(de)(de)英文縮寫。從表(biao)中(zhong)(zhong)可(ke)見，可(ke)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)次數和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)深(shen)度(du)(du)有(you)關，10%DOD時(shi)(shi)的(de)(de)(de)(de)循(xun)(xun)環壽(shou)命要(yao)比100%DOD的(de)(de)(de)(de)要(yao)長(chang)很(hen)多。當然如(ru)果(guo)折合到(dao)(dao)實(shi)際充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)相(xiang)對(dui)總容量(liang)(liang)：10%*1000=100，100%*200=200，后(hou)者的(de)(de)(de)(de)完全充(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)還(huan)是(shi)(shi)(shi)要(yao)比較好一(yi)些(xie)，但前(qian)面網(wang)友的(de)(de)(de)(de)那(nei)個(ge)說法要(yao)做一(yi)些(xie)修(xiu)正(zheng)：在正(zheng)常情況(kuang)下(xia)，你(ni)(ni)應(ying)該有(you)保留(liu)地按照電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)用(yong)完再充(chong)(chong)(chong)的(de)(de)(de)(de)原則充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，但假(jia)如(ru)你(ni)(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)在你(ni)(ni)預(yu)計(ji)第2天不可(ke)能堅持整(zheng)個(ge)白天的(de)(de)(de)(de)時(shi)(shi)候(hou)，就(jiu)應(ying)該及時(shi)(shi)開始充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當然你(ni)(ni)如(ru)果(guo)愿(yuan)意(yi)背著(zhu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器到(dao)(dao)辦公(gong)室又(you)當別論。而你(ni)(ni)需要(yao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)以應(ying)付預(yu)計(ji)即(ji)將到(dao)(dao)來(lai)的(de)(de)(de)(de)會導(dao)致通(tong)訊(xun)繁忙的(de)(de)(de)(de)重要(yao)事件的(de)(de)(de)(de)時(shi)(shi)候(hou)，即(ji)使在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)尚(shang)有(you)很(hen)多余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)，那(nei)么你(ni)(ni)也只管提前(qian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，因為你(ni)(ni)并(bing)沒有(you)真正(zheng)損失“1”次充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)循(xun)(xun)環壽(shou)命，也就(jiu)是(shi)(shi)(shi)“0.x”次而已，而且往往這(zhe)(zhe)個(ge)x會很(hen)小(xiao)。 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)用(yong)完再充(chong)(chong)(chong)的(de)(de)(de)(de)原則并(bing)不是(shi)(shi)(shi)要(yao)你(ni)(ni)走(zou)向極(ji)端。和長(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)一(yi)樣流(liu)傳甚(shen)廣的(de)(de)(de)(de)一(yi)個(ge)說法，就(jiu)是(shi)(shi)(shi)“盡量(liang)(liang)把手(shou)機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)用(yong)完，最(zui)好用(yong)到(dao)(dao)自(zi)動關機(ji)”。這(zhe)(zhe)種做法其(qi)實(shi)只是(shi)(shi)(shi)鎳電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)上的(de)(de)(de)(de)做法，目的(de)(de)(de)(de)是(shi)(shi)(shi)避免記憶效應(ying)發生，不幸的(de)(de)(de)(de)是(shi)(shi)(shi)它也在鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)上流(liu)傳之(zhi)今。曾經有(you)人因為手(shou)機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)過低的(de)(de)(de)(de)警告出現(xian)后(hou)，仍(reng)然不充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)繼續使用(yong)一(yi)直用(yong)到(dao)(dao)自(zi)動關機(ji)的(de)(de)(de)(de)例子。結果(guo)這(zhe)(zhe)個(ge)例子中(zhong)(zhong)的(de)(de)(de)(de)手(shou)機(ji)在后(hou)來(lai)的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)及開機(ji)中(zhong)(zhong)均(jun)無反(fan)應(ying)，不得不送客服檢修(xiu)。這(zhe)(zhe)其(qi)實(shi)就(jiu)是(shi)(shi)(shi)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)因過度(du)(du)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)而導(dao)致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓過低，以至于不具(ju)備正(zheng)常的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和開機(ji)條件造成的(de)(de)(de)(de)。

3、對鋰電池手機的正確做法

歸結起來，我對(dui)鋰電(dian)池手機在使用中的(de)充(chong)放電(dian)問題最重要(yao)的(de)提示(shi)是：

1、按照標準的時間和程序充電，即使是前三次也要如此進行；

2、當出現手機電量過(guo)低(di)提示(shi)時(shi)(shi)，應該盡量及時(shi)(shi)開(kai)始(shi)充電；

3、鋰(li)電池的(de)激(ji)活并不需要特別的(de)方(fang)法(fa)，在(zai)手機(ji)正(zheng)常使(shi)用中鋰(li)電池會自然激(ji)活。如果(guo)你(ni)執意要用流傳(chuan)的(de)“前三(san)次12小(xiao)時長充電激(ji)活”方(fang)法(fa)，實際上也不會有效果(guo)。

因此，所有追求12小時超長充(chong)電和把鋰電池手(shou)機(ji)用到(dao)自動關機(ji)的做法(fa)，都是錯誤(wu)(wu)的。如(ru)果你以前是按照錯誤(wu)(wu)的說(shuo)法(fa)做的，請你及時改正，也(ye)許為時還不晚。

    當(dang)然，在手機及充電(dian)器自身保(bao)護(hu)和(he)控制電(dian)路質量良好的情況下，對鋰電(dian)池(chi)的保(bao)護(hu)還(huan)是(shi)有相(xiang)當(dang)保(bao)證的。所以對充電(dian)規則的理解才是(shi)重點，在某些情況下也是(shi)可以做(zuo)出某種(zhong)讓步的。比如你(ni)發現手機在你(ni)夜晚睡覺前必須充電(dian)的話，你(ni)也可以在睡前開始充電(dian)。問題的關鍵在于，你(ni)應(ying)該知道正確(que)的做(zuo)法是(shi)什(shen)么，并且不要刻意按(an)照錯誤的說(shuo)法去做(zuo)。

希(xi)望大(da)家努力掌握關于鋰(li)(li)電(dian)池的知(zhi)識和學會正確使用(yong)鋰(li)(li)電(dian)池的科學方法(fa)，早日在鋰(li)(li)電(dian)池的手機上與流傳(chuan)已久的錯誤(wu)說法(fa)和做法(fa)告(gao)別(bie)。
