在使用手機時，值得大家應注意的是鋰電池，電(dian)(dian)池(chi)放置一(yi)段時間(jian)后則進入休眠狀態，此時容(rong)量(liang)低(di)于正常值，使(shi)用(yong)時間(jian)亦隨之縮短(duan)。但鋰電(dian)(dian)池(chi)很容(rong)易激(ji)活(huo)，只要經(jing)過(guo)3―5次正常的充放電(dian)(dian)循環就(jiu)可激(ji)活(huo)電(dian)(dian)池(chi)，恢復正常容(rong)量(liang)。由于鋰電(dian)(dian)池(chi)本身的特性(xing)，決定了它(ta)幾乎沒有(you)記(ji)憶效(xiao)應。因此用(yong)戶手機中(zhong)的新鋰電(dian)(dian)池(chi)在激(ji)活(huo)過(guo)程中(zhong)，是不需(xu)要特別的方法和(he)設備的。不僅(jin)理(li)論上是如此，從(cong)(cong)我自己的實踐來(lai)看，從(cong)(cong)一(yi)開始就(jiu)采用(yong)標準方法充電(dian)(dian)這種(zhong)“自然激(ji)活(huo)”方式(shi)是最好的。

     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(hai)。因而充(chong)電最好按照標準(zhun)時間和標準(zhun)方法充(chong)電，特別是(shi)不要進行超過12個小時的超長充(chong)電。通常(chang)，手(shou)機說明(ming)書上介紹的充(chong)電方法，就是(shi)適合該(gai)手(shou)機的標準(zhun)充(chong)電方法。

    此外，鋰(li)電(dian)(dian)池(chi)的(de)(de)手機或充(chong)(chong)電(dian)(dian)器(qi)(qi)在(zai)電(dian)(dian)池(chi)充(chong)(chong)滿后都會自動停充(chong)(chong)，并不存在(zai)鎳(nie)電(dian)(dian)充(chong)(chong)電(dian)(dian)器(qi)(qi)所(suo)謂的(de)(de)持續10幾小時(shi)的(de)(de)“涓流”充(chong)(chong)電(dian)(dian)。也(ye)就是說，如果你的(de)(de)鋰(li)電(dian)(dian)池(chi)在(zai)充(chong)(chong)滿后，放(fang)(fang)在(zai)充(chong)(chong)電(dian)(dian)器(qi)(qi)上(shang)也(ye)是白(bai)充(chong)(chong)。而我(wo)們誰都無法保(bao)證電(dian)(dian)池(chi)的(de)(de)充(chong)(chong)放(fang)(fang)電(dian)(dian)保(bao)護電(dian)(dian)路(lu)的(de)(de)特性永不變化和質量的(de)(de)萬無一失，所(suo)以你的(de)(de)電(dian)(dian)池(chi)將長期處在(zai)危(wei)險的(de)(de)邊緣徘徊。這也(ye)是我(wo)們反對長充(chong)(chong)電(dian)(dian)的(de)(de)另一個理由。

1、此外(wai)在對(dui)某些手(shou)機上，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)超過(guo)一(yi)定(ding)的(de)(de)(de)時(shi)間(jian)(jian)后，如果不(bu)去取(qu)下充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，這時(shi)系統不(bu)僅不(bu)停止(zhi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，還將開始放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)-充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)循環。也(ye)(ye)許這種做(zuo)法的(de)(de)(de)廠商自(zi)有其目的(de)(de)(de)，但顯然(ran)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)池和手(shou)機/充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)壽命而(er)(er)言是不(bu)利的(de)(de)(de)。同(tong)時(shi)，長(chang)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)需要很(hen)長(chang)的(de)(de)(de)時(shi)間(jian)(jian)，往往需要在夜間(jian)(jian)進行，而(er)(er)以我國電(dian)(dian)(dian)(dian)(dian)(dian)網的(de)(de)(de)情(qing)況看(kan)，許多(duo)地方夜間(jian)(jian)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓都比(bi)較高(gao)，而(er)(er)且波動(dong)較大。前面已經說過(guo)，鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池是很(hen)嬌貴的(de)(de)(de)，它比(bi)鎳電(dian)(dian)(dian)(dian)(dian)(dian)在充(chong)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)方面耐波動(dong)的(de)(de)(de)能力差得多(duo)，于是這又帶來附加(jia)的(de)(de)(de)危險。 此外(wai)，不(bu)可忽視(shi)的(de)(de)(de)另(ling)外(wai)一(yi)個方面就是鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池同(tong)樣也(ye)(ye)不(bu)適合(he)過(guo)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，過(guo)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)對(dui)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池同(tong)樣也(ye)(ye)很(hen)不(bu)利。

2、正常使(shi)用中應該(gai)何(he)時(shi)開始(shi)充電

在我們(men)的(de)(de)(de)論(lun)壇上，經常可(ke)以見到這種說法，因為充(chong)放電的(de)(de)(de)次數(shu)(shu)是有限的(de)(de)(de)，所以應該將手(shou)機電池(chi)的(de)(de)(de)電盡可(ke)能用光再充(chong)電。但(dan)是我找到一個關于(yu)鋰離子電池(chi)充(chong)放電循(xun)環的(de)(de)(de)實驗(yan)表，關于(yu)循(xun)環壽命的(de)(de)(de)數(shu)(shu)據列出如下：

循環(huan)壽命 (10%DOD):>1000次

循(xun)環壽命 (100%DOD):>200次

其中(zhong)DOD是(shi)(shi)(shi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)深度的(de)(de)(de)英文(wen)縮寫。從表中(zhong)可(ke)見，可(ke)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)次數(shu)和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)深度有關(guan)，10%DOD時(shi)(shi)的(de)(de)(de)循(xun)環壽命(ming)要比100%DOD的(de)(de)(de)要長很(hen)多。當然如(ru)果折合到(dao)實(shi)(shi)(shi)際充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)相(xiang)對總容量(liang)(liang)(liang)：10%*1000=100，100%*200=200，后(hou)者的(de)(de)(de)完全充放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)還是(shi)(shi)(shi)要比較(jiao)好一(yi)些，但(dan)前面網(wang)友的(de)(de)(de)那(nei)個(ge)說(shuo)法(fa)(fa)(fa)(fa)要做一(yi)些修正：在(zai)正常(chang)情(qing)況下(xia)，你(ni)(ni)(ni)應該有保留地按照電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)剩(sheng)余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)用(yong)(yong)(yong)(yong)完再充的(de)(de)(de)原則充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，但(dan)假如(ru)你(ni)(ni)(ni)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)在(zai)你(ni)(ni)(ni)預(yu)計第2天不(bu)(bu)(bu)可(ke)能堅持整個(ge)白天的(de)(de)(de)時(shi)(shi)候，就應該及時(shi)(shi)開始(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當然你(ni)(ni)(ni)如(ru)果愿意(yi)背著充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)到(dao)辦公室(shi)又(you)當別論。而(er)你(ni)(ni)(ni)需要充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)以(yi)應付預(yu)計即(ji)將到(dao)來的(de)(de)(de)會(hui)導致(zhi)通訊繁(fan)忙的(de)(de)(de)重要事件的(de)(de)(de)時(shi)(shi)候，即(ji)使(shi)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)尚(shang)有很(hen)多余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)，那(nei)么你(ni)(ni)(ni)也(ye)(ye)只(zhi)(zhi)管提前充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，因為(wei)你(ni)(ni)(ni)并(bing)沒(mei)有真正損失“1”次充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)循(xun)環壽命(ming)，也(ye)(ye)就是(shi)(shi)(shi)“0.x”次而(er)已，而(er)且(qie)往(wang)往(wang)這(zhe)個(ge)x會(hui)很(hen)小。 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)剩(sheng)余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)用(yong)(yong)(yong)(yong)完再充的(de)(de)(de)原則并(bing)不(bu)(bu)(bu)是(shi)(shi)(shi)要你(ni)(ni)(ni)走(zou)向極端。和(he)長充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)一(yi)樣流傳(chuan)甚廣的(de)(de)(de)一(yi)個(ge)說(shuo)法(fa)(fa)(fa)(fa)，就是(shi)(shi)(shi)“盡(jin)量(liang)(liang)(liang)把(ba)手機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)用(yong)(yong)(yong)(yong)完，最好用(yong)(yong)(yong)(yong)到(dao)自(zi)(zi)動(dong)關(guan)機(ji)(ji)(ji)”。這(zhe)種(zhong)做法(fa)(fa)(fa)(fa)其實(shi)(shi)(shi)只(zhi)(zhi)是(shi)(shi)(shi)鎳電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)上的(de)(de)(de)做法(fa)(fa)(fa)(fa)，目的(de)(de)(de)是(shi)(shi)(shi)避免記(ji)憶(yi)效應發生，不(bu)(bu)(bu)幸的(de)(de)(de)是(shi)(shi)(shi)它也(ye)(ye)在(zai)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)上流傳(chuan)之今。曾經(jing)有人因為(wei)手機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)過(guo)(guo)(guo)低的(de)(de)(de)警告(gao)出(chu)現后(hou)，仍然不(bu)(bu)(bu)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)繼續使(shi)用(yong)(yong)(yong)(yong)一(yi)直用(yong)(yong)(yong)(yong)到(dao)自(zi)(zi)動(dong)關(guan)機(ji)(ji)(ji)的(de)(de)(de)例子。結(jie)果這(zhe)個(ge)例子中(zhong)的(de)(de)(de)手機(ji)(ji)(ji)在(zai)后(hou)來的(de)(de)(de)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)及開機(ji)(ji)(ji)中(zhong)均(jun)無(wu)反應，不(bu)(bu)(bu)得(de)不(bu)(bu)(bu)送(song)客服檢修。這(zhe)其實(shi)(shi)(shi)就是(shi)(shi)(shi)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)因過(guo)(guo)(guo)度放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)而(er)導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓過(guo)(guo)(guo)低，以(yi)至于不(bu)(bu)(bu)具備(bei)正常(chang)的(de)(de)(de)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和(he)開機(ji)(ji)(ji)條(tiao)件造成的(de)(de)(de)。

3、對鋰電池手機(ji)的正確做(zuo)法

歸結起來，我對鋰(li)電(dian)池手機在使用(yong)中的充放(fang)電(dian)問題最重要(yao)的提示是(shi)：

1、按(an)照(zhao)標準(zhun)的時間和程(cheng)序充電，即使是前三次也要如此進(jin)行；

2、當出現手機電(dian)量過低(di)提示(shi)時，應(ying)該盡量及時開始充電(dian)；

3、鋰(li)電(dian)池(chi)的(de)激活并不需(xu)要特別的(de)方法，在手(shou)機正(zheng)常使用(yong)中鋰(li)電(dian)池(chi)會自然激活。如果你執意(yi)要用(yong)流傳的(de)“前(qian)三次12小時長(chang)充電(dian)激活”方法，實(shi)際(ji)上(shang)也不會有效果。

因此，所有追求12小時(shi)超長(chang)充電和把(ba)鋰電池手機用(yong)到自動關(guan)機的做(zuo)法，都(dou)是錯(cuo)誤(wu)的。如果你(ni)以(yi)前是按照(zhao)錯(cuo)誤(wu)的說法做(zuo)的，請你(ni)及時(shi)改(gai)正(zheng)，也(ye)許為(wei)時(shi)還不晚(wan)。

    當然，在手機(ji)及充電(dian)器自身保(bao)護和(he)控制電(dian)路質量良好(hao)的(de)(de)(de)(de)情況下(xia)，對(dui)(dui)鋰電(dian)池的(de)(de)(de)(de)保(bao)護還是(shi)(shi)有相(xiang)當保(bao)證的(de)(de)(de)(de)。所以(yi)對(dui)(dui)充電(dian)規則的(de)(de)(de)(de)理解(jie)才是(shi)(shi)重點，在某些(xie)情況下(xia)也(ye)(ye)是(shi)(shi)可以(yi)做(zuo)出(chu)某種(zhong)讓(rang)步的(de)(de)(de)(de)。比如你(ni)發(fa)現手機(ji)在你(ni)夜(ye)晚(wan)睡覺前必(bi)須充電(dian)的(de)(de)(de)(de)話(hua)，你(ni)也(ye)(ye)可以(yi)在睡前開始充電(dian)。問(wen)題的(de)(de)(de)(de)關鍵在于，你(ni)應該知道正(zheng)確(que)的(de)(de)(de)(de)做(zuo)法(fa)是(shi)(shi)什么，并且(qie)不要刻意(yi)按照錯誤的(de)(de)(de)(de)說(shuo)法(fa)去做(zuo)。

希望(wang)大(da)家努力(li)掌握(wo)關(guan)于鋰(li)(li)電(dian)池(chi)的(de)知識和學(xue)會正確使用鋰(li)(li)電(dian)池(chi)的(de)科學(xue)方法，早日在鋰(li)(li)電(dian)池(chi)的(de)手機上與流傳已(yi)久的(de)錯誤說(shuo)法和做法告(gao)別。
