在使用手機時，值得大家應注意的是鋰電池，電池(chi)放置(zhi)一段時間后(hou)則(ze)進(jin)入休眠狀態，此時容量(liang)低于正(zheng)(zheng)常值，使用時間亦隨(sui)之縮(suo)短。但鋰電池(chi)很容易(yi)激(ji)(ji)活(huo)，只(zhi)要經(jing)過3―5次正(zheng)(zheng)常的(de)充(chong)放電循環(huan)就(jiu)可激(ji)(ji)活(huo)電池(chi)，恢復正(zheng)(zheng)常容量(liang)。由(you)于鋰電池(chi)本身的(de)特(te)性，決(jue)定了它(ta)幾(ji)乎(hu)沒有記憶效應。因此用戶(hu)手機中的(de)新(xin)鋰電池(chi)在激(ji)(ji)活(huo)過程中，是不(bu)需要特(te)別的(de)方(fang)(fang)法(fa)和設備(bei)的(de)。不(bu)僅理論上是如此，從我自己的(de)實踐(jian)來看，從一開始就(jiu)采(cai)用標準方(fang)(fang)法(fa)充(chong)電這種“自然激(ji)(ji)活(huo)”方(fang)(fang)式是最好的(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成巨大的傷(shang)害。因而充電(dian)最好按照標(biao)準時間(jian)和標(biao)準方(fang)法充電(dian)，特別(bie)是(shi)不要進行超過12個小時的超長(chang)充電(dian)。通常，手機(ji)說明書上介紹的充電(dian)方(fang)法，就(jiu)是(shi)適合該手機(ji)的標(biao)準充電(dian)方(fang)法。

    此外，鋰電(dian)(dian)池(chi)(chi)的(de)(de)手機或充(chong)(chong)電(dian)(dian)器在電(dian)(dian)池(chi)(chi)充(chong)(chong)滿(man)后都(dou)會(hui)自(zi)動停(ting)充(chong)(chong)，并不存在鎳電(dian)(dian)充(chong)(chong)電(dian)(dian)器所(suo)謂的(de)(de)持續10幾小時的(de)(de)“涓流”充(chong)(chong)電(dian)(dian)。也就是說(shuo)，如果你(ni)的(de)(de)鋰電(dian)(dian)池(chi)(chi)在充(chong)(chong)滿(man)后，放在充(chong)(chong)電(dian)(dian)器上也是白充(chong)(chong)。而我們(men)誰都(dou)無法保證電(dian)(dian)池(chi)(chi)的(de)(de)充(chong)(chong)放電(dian)(dian)保護電(dian)(dian)路的(de)(de)特(te)性(xing)永不變化和質量的(de)(de)萬(wan)無一(yi)失，所(suo)以(yi)你(ni)的(de)(de)電(dian)(dian)池(chi)(chi)將長期(qi)處(chu)在危(wei)險(xian)的(de)(de)邊緣徘徊。這也是我們(men)反對長充(chong)(chong)電(dian)(dian)的(de)(de)另一(yi)個理由。

1、此外(wai)在(zai)對(dui)某些手機(ji)上，充(chong)(chong)電(dian)(dian)(dian)超過一(yi)定(ding)的(de)時間后(hou)，如果不(bu)去取下充(chong)(chong)電(dian)(dian)(dian)器，這(zhe)時系(xi)統不(bu)僅不(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。也許這(zhe)種做法的(de)廠商自有其目的(de)，但顯(xian)然對(dui)電(dian)(dian)(dian)池(chi)和手機(ji)/充(chong)(chong)電(dian)(dian)(dian)器的(de)壽(shou)命(ming)而(er)言是(shi)不(bu)利的(de)。同(tong)(tong)時，長(chang)(chang)充(chong)(chong)電(dian)(dian)(dian)需要很長(chang)(chang)的(de)時間，往(wang)往(wang)需要在(zai)夜間進行，而(er)以我(wo)國電(dian)(dian)(dian)網的(de)情(qing)況看，許多地(di)方夜間的(de)電(dian)(dian)(dian)壓都比較(jiao)高(gao)，而(er)且波動(dong)(dong)較(jiao)大(da)。前面已經(jing)說(shuo)過，鋰電(dian)(dian)(dian)池(chi)是(shi)很嬌貴的(de)，它比鎳電(dian)(dian)(dian)在(zai)充(chong)(chong)放電(dian)(dian)(dian)方面耐波動(dong)(dong)的(de)能(neng)力差得多，于是(shi)這(zhe)又帶來(lai)附加的(de)危險(xian)。 此外(wai)，不(bu)可忽視(shi)的(de)另(ling)外(wai)一(yi)個方面就是(shi)鋰電(dian)(dian)(dian)池(chi)同(tong)(tong)樣也不(bu)適合過放電(dian)(dian)(dian)，過放電(dian)(dian)(dian)對(dui)鋰電(dian)(dian)(dian)池(chi)同(tong)(tong)樣也很不(bu)利。

2、正常使(shi)用(yong)中應該何(he)時開始(shi)充電

在我(wo)們(men)的(de)論(lun)壇(tan)上，經常可以(yi)見(jian)到(dao)這種(zhong)說法，因(yin)為(wei)充放電(dian)(dian)的(de)次數是(shi)有(you)限的(de)，所以(yi)應該將(jiang)手機電(dian)(dian)池的(de)電(dian)(dian)盡可能用光(guang)再(zai)充電(dian)(dian)。但是(shi)我(wo)找到(dao)一個關于鋰離子(zi)電(dian)(dian)池充放電(dian)(dian)循環的(de)實驗表，關于循環壽命的(de)數據列(lie)出如(ru)下：

循環壽命 (10%DOD):>1000次

循環壽命 (100%DOD):>200次

其中(zhong)DOD是(shi)(shi)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)深(shen)度(du)的(de)(de)(de)英文縮寫(xie)。從(cong)表(biao)中(zhong)可見，可充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)次(ci)數(shu)和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)深(shen)度(du)有(you)(you)關，10%DOD時的(de)(de)(de)循環(huan)壽(shou)命(ming)要比(bi)100%DOD的(de)(de)(de)要長很(hen)多。當然(ran)(ran)如(ru)果(guo)折合到(dao)(dao)實際充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)相對(dui)總容量：10%*1000=100，100%*200=200，后(hou)(hou)者的(de)(de)(de)完(wan)全充(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)還是(shi)(shi)要比(bi)較好一些，但前面網友的(de)(de)(de)那(nei)(nei)個(ge)說(shuo)法要做(zuo)一些修正：在(zai)正常(chang)情況(kuang)下，你(ni)(ni)(ni)(ni)應(ying)(ying)該(gai)有(you)(you)保留(liu)地按(an)照(zhao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)剩(sheng)余電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量用(yong)(yong)完(wan)再充(chong)(chong)(chong)的(de)(de)(de)原則(ze)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，但假如(ru)你(ni)(ni)(ni)(ni)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)在(zai)你(ni)(ni)(ni)(ni)預計第2天(tian)不(bu)可能(neng)堅持(chi)整個(ge)白天(tian)的(de)(de)(de)時候，就(jiu)(jiu)(jiu)應(ying)(ying)該(gai)及時開始(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當然(ran)(ran)你(ni)(ni)(ni)(ni)如(ru)果(guo)愿(yuan)意(yi)背著充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器到(dao)(dao)辦公室又當別(bie)論。而你(ni)(ni)(ni)(ni)需要充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)以應(ying)(ying)付(fu)預計即將到(dao)(dao)來(lai)的(de)(de)(de)會導致通訊繁忙的(de)(de)(de)重要事件的(de)(de)(de)時候，即使在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)尚有(you)(you)很(hen)多余電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時，那(nei)(nei)么你(ni)(ni)(ni)(ni)也只管提前充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，因(yin)為(wei)你(ni)(ni)(ni)(ni)并(bing)沒有(you)(you)真正損失“1”次(ci)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)循環(huan)壽(shou)命(ming)，也就(jiu)(jiu)(jiu)是(shi)(shi)“0.x”次(ci)而已，而且往(wang)往(wang)這(zhe)個(ge)x會很(hen)小。 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)剩(sheng)余電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量用(yong)(yong)完(wan)再充(chong)(chong)(chong)的(de)(de)(de)原則(ze)并(bing)不(bu)是(shi)(shi)要你(ni)(ni)(ni)(ni)走向極端(duan)。和長充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)一樣流傳甚廣的(de)(de)(de)一個(ge)說(shuo)法，就(jiu)(jiu)(jiu)是(shi)(shi)“盡量把手(shou)(shou)(shou)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量用(yong)(yong)完(wan)，最好用(yong)(yong)到(dao)(dao)自(zi)動(dong)關機(ji)(ji)(ji)”。這(zhe)種做(zuo)法其實只是(shi)(shi)鎳電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)上的(de)(de)(de)做(zuo)法，目(mu)的(de)(de)(de)是(shi)(shi)避(bi)免(mian)記憶效應(ying)(ying)發生，不(bu)幸的(de)(de)(de)是(shi)(shi)它(ta)也在(zai)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)上流傳之(zhi)今。曾經有(you)(you)人因(yin)為(wei)手(shou)(shou)(shou)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量過(guo)低(di)的(de)(de)(de)警告(gao)出(chu)現后(hou)(hou)，仍(reng)然(ran)(ran)不(bu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)繼續使用(yong)(yong)一直(zhi)用(yong)(yong)到(dao)(dao)自(zi)動(dong)關機(ji)(ji)(ji)的(de)(de)(de)例(li)子。結果(guo)這(zhe)個(ge)例(li)子中(zhong)的(de)(de)(de)手(shou)(shou)(shou)機(ji)(ji)(ji)在(zai)后(hou)(hou)來(lai)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)及開機(ji)(ji)(ji)中(zhong)均無反應(ying)(ying)，不(bu)得(de)不(bu)送客服檢修。這(zhe)其實就(jiu)(jiu)(jiu)是(shi)(shi)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)因(yin)過(guo)度(du)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)而導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓過(guo)低(di)，以至于不(bu)具備正常(chang)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)和開機(ji)(ji)(ji)條件造成(cheng)的(de)(de)(de)。

3、對鋰電池手機的正(zheng)確(que)做法

歸(gui)結起(qi)來，我對鋰電(dian)池手機在使用中的充(chong)放(fang)電(dian)問題最(zui)重要的提示(shi)是：

1、按照標準的時間和程序充電(dian)，即(ji)使是前三(san)次也要如此進行；

2、當出現手(shou)機電(dian)量(liang)過低提示時，應該盡量(liang)及時開始充電(dian)；

3、鋰電(dian)池的激活(huo)(huo)并不(bu)需要特別的方(fang)法(fa)，在手機(ji)正常(chang)使用中鋰電(dian)池會自然激活(huo)(huo)。如果(guo)你執意要用流傳(chuan)的“前三次(ci)12小時長(chang)充電(dian)激活(huo)(huo)”方(fang)法(fa)，實際上也不(bu)會有效果(guo)。

因此，所有追求12小時超長充電和把鋰(li)電池(chi)手機用(yong)到(dao)自(zi)動(dong)關機的(de)做法，都是(shi)(shi)錯誤的(de)。如果你(ni)以前是(shi)(shi)按照錯誤的(de)說法做的(de)，請你(ni)及(ji)時改正，也許為時還(huan)不晚。

    當然(ran)，在(zai)手機及(ji)充電器自(zi)身保(bao)護(hu)和控制電路質量良好(hao)的(de)情(qing)況下，對鋰(li)電池的(de)保(bao)護(hu)還是有相(xiang)當保(bao)證的(de)。所以(yi)對充電規則的(de)理(li)解(jie)才是重點(dian)，在(zai)某(mou)些情(qing)況下也是可(ke)以(yi)做出某(mou)種讓步的(de)。比如(ru)你(ni)發現手機在(zai)你(ni)夜晚睡覺(jue)前必(bi)須充電的(de)話，你(ni)也可(ke)以(yi)在(zai)睡前開始充電。問題的(de)關鍵(jian)在(zai)于，你(ni)應該知道正確的(de)做法是什么，并且不要刻意按照錯誤的(de)說(shuo)法去做。

希望大家努力(li)掌握關于鋰(li)電池的(de)(de)知識和(he)學(xue)會(hui)正確使用鋰(li)電池的(de)(de)科學(xue)方(fang)法，早(zao)日在(zai)鋰(li)電池的(de)(de)手(shou)機(ji)上與流(liu)傳已久的(de)(de)錯誤說(shuo)法和(he)做法告(gao)別。
