在使用手機時，值得大家應注意的是鋰電池，電池(chi)放(fang)置一(yi)段(duan)時間后則(ze)進入(ru)休眠狀態，此時容(rong)(rong)量低于(yu)正(zheng)常(chang)值，使用時間亦隨之縮短。但鋰(li)電池(chi)很容(rong)(rong)易(yi)激活(huo)(huo)(huo)，只要經過(guo)3―5次(ci)正(zheng)常(chang)的(de)(de)(de)(de)充(chong)放(fang)電循(xun)環就可激活(huo)(huo)(huo)電池(chi)，恢復正(zheng)常(chang)容(rong)(rong)量。由于(yu)鋰(li)電池(chi)本身的(de)(de)(de)(de)特性，決定(ding)了(le)它幾乎沒有記憶(yi)效應(ying)。因此用戶(hu)手機中的(de)(de)(de)(de)新(xin)鋰(li)電池(chi)在激活(huo)(huo)(huo)過(guo)程中，是不(bu)需要特別的(de)(de)(de)(de)方(fang)法(fa)和(he)設(she)備的(de)(de)(de)(de)。不(bu)僅理論上是如此，從(cong)我自(zi)(zi)己(ji)的(de)(de)(de)(de)實(shi)踐來看，從(cong)一(yi)開始就采用標準方(fang)法(fa)充(chong)電這(zhe)種“自(zi)(zi)然激活(huo)(huo)(huo)”方(fang)式是最好的(de)(de)(de)(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害。因(yin)而充(chong)電(dian)最好(hao)按(an)照標(biao)準(zhun)時間和(he)標(biao)準(zhun)方(fang)法(fa)(fa)充(chong)電(dian)，特別是(shi)(shi)不要進行(xing)超過12個小時的超長充(chong)電(dian)。通常，手(shou)機(ji)說明(ming)書上介紹的充(chong)電(dian)方(fang)法(fa)(fa)，就是(shi)(shi)適合該手(shou)機(ji)的標(biao)準(zhun)充(chong)電(dian)方(fang)法(fa)(fa)。

    此外(wai)，鋰電(dian)(dian)(dian)池(chi)的(de)(de)手機或充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)在(zai)(zai)電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)滿后(hou)都會自動停充(chong)(chong)(chong)，并不存(cun)在(zai)(zai)鎳電(dian)(dian)(dian)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)所謂的(de)(de)持續10幾小時(shi)的(de)(de)“涓(juan)流(liu)”充(chong)(chong)(chong)電(dian)(dian)(dian)。也就是說(shuo)，如(ru)果(guo)你的(de)(de)鋰電(dian)(dian)(dian)池(chi)在(zai)(zai)充(chong)(chong)(chong)滿后(hou)，放在(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)上也是白充(chong)(chong)(chong)。而我(wo)們誰都無(wu)法保證電(dian)(dian)(dian)池(chi)的(de)(de)充(chong)(chong)(chong)放電(dian)(dian)(dian)保護電(dian)(dian)(dian)路(lu)的(de)(de)特(te)性(xing)永(yong)不變化(hua)和質量的(de)(de)萬無(wu)一(yi)失，所以你的(de)(de)電(dian)(dian)(dian)池(chi)將長(chang)期處在(zai)(zai)危(wei)險的(de)(de)邊緣徘徊。這也是我(wo)們反對(dui)長(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)(de)另(ling)一(yi)個理由。

1、此(ci)外在(zai)對某些手(shou)機上(shang)，充電(dian)(dian)超過一(yi)定的(de)(de)時(shi)間(jian)(jian)后，如果不(bu)去取(qu)下(xia)充電(dian)(dian)器，這時(shi)系(xi)統不(bu)僅不(bu)停(ting)止充電(dian)(dian)，還將開始放(fang)(fang)電(dian)(dian)-充電(dian)(dian)循環(huan)。也許(xu)這種做法的(de)(de)廠(chang)商自有其(qi)目的(de)(de)，但顯然(ran)對電(dian)(dian)池(chi)和(he)手(shou)機/充電(dian)(dian)器的(de)(de)壽(shou)命而(er)(er)言是(shi)不(bu)利的(de)(de)。同(tong)時(shi)，長充電(dian)(dian)需(xu)要很(hen)(hen)長的(de)(de)時(shi)間(jian)(jian)，往(wang)往(wang)需(xu)要在(zai)夜間(jian)(jian)進行，而(er)(er)以我國電(dian)(dian)網的(de)(de)情(qing)況看，許(xu)多地方(fang)夜間(jian)(jian)的(de)(de)電(dian)(dian)壓都比(bi)較高，而(er)(er)且(qie)波動(dong)較大。前面(mian)已(yi)經(jing)說(shuo)過，鋰電(dian)(dian)池(chi)是(shi)很(hen)(hen)嬌貴的(de)(de)，它比(bi)鎳電(dian)(dian)在(zai)充放(fang)(fang)電(dian)(dian)方(fang)面(mian)耐(nai)波動(dong)的(de)(de)能力差得多，于(yu)是(shi)這又帶(dai)來附加(jia)的(de)(de)危險。 此(ci)外，不(bu)可忽(hu)視的(de)(de)另外一(yi)個方(fang)面(mian)就是(shi)鋰電(dian)(dian)池(chi)同(tong)樣也不(bu)適合過放(fang)(fang)電(dian)(dian)，過放(fang)(fang)電(dian)(dian)對鋰電(dian)(dian)池(chi)同(tong)樣也很(hen)(hen)不(bu)利。

2、正常使(shi)用中應該何時開始充電

在我們的(de)論(lun)壇上，經常可(ke)以(yi)見到(dao)這種說法(fa)，因為充(chong)放電(dian)的(de)次數(shu)是(shi)有限(xian)的(de)，所以(yi)應該將手機電(dian)池的(de)電(dian)盡可(ke)能(neng)用光再充(chong)電(dian)。但(dan)是(shi)我找到(dao)一個關于(yu)鋰離(li)子電(dian)池充(chong)放電(dian)循環的(de)實(shi)驗表(biao)，關于(yu)循環壽命的(de)數(shu)據列出如下：

循環壽命 (10%DOD):>1000次

循(xun)環壽命 (100%DOD):>200次

其(qi)中(zhong)DOD是(shi)放(fang)電(dian)(dian)(dian)(dian)深度(du)的(de)(de)(de)(de)英文縮寫。從表中(zhong)可(ke)(ke)見，可(ke)(ke)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)次(ci)數(shu)和放(fang)電(dian)(dian)(dian)(dian)深度(du)有(you)(you)關(guan)(guan)，10%DOD時的(de)(de)(de)(de)循(xun)環壽(shou)命要(yao)(yao)比100%DOD的(de)(de)(de)(de)要(yao)(yao)長(chang)很(hen)多。當(dang)然如果(guo)(guo)折合到實際充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)相對總容量：10%*1000=100，100%*200=200，后(hou)(hou)者的(de)(de)(de)(de)完全充(chong)(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)還是(shi)要(yao)(yao)比較好一些，但前面(mian)網友的(de)(de)(de)(de)那個說法要(yao)(yao)做一些修正：在正常(chang)情況下(xia)，你(ni)(ni)(ni)(ni)應(ying)(ying)(ying)該(gai)有(you)(you)保留地(di)按照電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)剩余(yu)電(dian)(dian)(dian)(dian)量用(yong)完再(zai)(zai)充(chong)(chong)(chong)的(de)(de)(de)(de)原則充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，但假如你(ni)(ni)(ni)(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)在你(ni)(ni)(ni)(ni)預計(ji)第2天(tian)不(bu)可(ke)(ke)能堅持整(zheng)個白天(tian)的(de)(de)(de)(de)時候，就(jiu)應(ying)(ying)(ying)該(gai)及時開始充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，當(dang)然你(ni)(ni)(ni)(ni)如果(guo)(guo)愿意(yi)背(bei)著充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)到辦公(gong)室又當(dang)別論。而你(ni)(ni)(ni)(ni)需要(yao)(yao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)以應(ying)(ying)(ying)付預計(ji)即(ji)將到來的(de)(de)(de)(de)會導致(zhi)通訊(xun)繁忙的(de)(de)(de)(de)重(zhong)要(yao)(yao)事件的(de)(de)(de)(de)時候，即(ji)使在電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)尚有(you)(you)很(hen)多余(yu)電(dian)(dian)(dian)(dian)時，那么你(ni)(ni)(ni)(ni)也(ye)只(zhi)管提前充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，因為你(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)循(xun)環壽(shou)命，也(ye)就(jiu)是(shi)“0.x”次(ci)而已，而且(qie)往(wang)往(wang)這個x會很(hen)小。 電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)剩余(yu)電(dian)(dian)(dian)(dian)量用(yong)完再(zai)(zai)充(chong)(chong)(chong)的(de)(de)(de)(de)原則并(bing)不(bu)是(shi)要(yao)(yao)你(ni)(ni)(ni)(ni)走向極端。和長(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)一樣流傳甚廣(guang)的(de)(de)(de)(de)一個說法，就(jiu)是(shi)“盡量把手機(ji)(ji)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)量用(yong)完，最好用(yong)到自(zi)動關(guan)(guan)機(ji)(ji)”。這種做法其(qi)實只(zhi)是(shi)鎳電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)上(shang)的(de)(de)(de)(de)做法，目(mu)的(de)(de)(de)(de)是(shi)避免記憶效應(ying)(ying)(ying)發生(sheng)，不(bu)幸(xing)的(de)(de)(de)(de)是(shi)它也(ye)在鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)上(shang)流傳之今。曾經(jing)有(you)(you)人因為手機(ji)(ji)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)量過(guo)(guo)低的(de)(de)(de)(de)警告出現后(hou)(hou)，仍然不(bu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)繼(ji)續使用(yong)一直用(yong)到自(zi)動關(guan)(guan)機(ji)(ji)的(de)(de)(de)(de)例(li)(li)子(zi)。結果(guo)(guo)這個例(li)(li)子(zi)中(zhong)的(de)(de)(de)(de)手機(ji)(ji)在后(hou)(hou)來的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)及開機(ji)(ji)中(zhong)均無反(fan)應(ying)(ying)(ying)，不(bu)得不(bu)送(song)客(ke)服檢(jian)修。這其(qi)實就(jiu)是(shi)由于電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)因過(guo)(guo)度(du)放(fang)電(dian)(dian)(dian)(dian)而導致(zhi)電(dian)(dian)(dian)(dian)壓過(guo)(guo)低，以至于不(bu)具備正常(chang)的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)和開機(ji)(ji)條(tiao)件造成的(de)(de)(de)(de)。

3、對鋰電池手機的(de)正確做法(fa)

歸(gui)結起來(lai)，我(wo)對鋰電池手機(ji)在使(shi)用中(zhong)的充放電問題最(zui)重要的提示是：

1、按照標準的時間和程(cheng)序充(chong)電，即使是前三次(ci)也要(yao)如(ru)此進行；

2、當出現(xian)手(shou)機電(dian)量過低提示(shi)時，應該盡(jin)量及(ji)時開始充電(dian)；

3、鋰(li)電(dian)池(chi)的激(ji)活并不需要(yao)特別(bie)的方(fang)法，在手(shou)機正常使用(yong)中鋰(li)電(dian)池(chi)會自然(ran)激(ji)活。如果你執意要(yao)用(yong)流傳的“前(qian)三次(ci)12小時長充電(dian)激(ji)活”方(fang)法，實(shi)際上也(ye)不會有(you)效果。

因此，所(suo)有追求12小(xiao)時超長充電(dian)和把鋰電(dian)池手(shou)機用到(dao)自動關機的(de)做法(fa)，都是錯誤(wu)的(de)。如果你以前是按照(zhao)錯誤(wu)的(de)說法(fa)做的(de)，請(qing)你及時改(gai)正，也許為時還不(bu)晚。

    當(dang)然，在(zai)(zai)手(shou)機及充(chong)電(dian)器(qi)自身保護和控(kong)制電(dian)路質量(liang)良好的(de)(de)情況下，對鋰電(dian)池的(de)(de)保護還是(shi)有相當(dang)保證的(de)(de)。所以(yi)(yi)對充(chong)電(dian)規則的(de)(de)理解才是(shi)重點，在(zai)(zai)某(mou)些情況下也是(shi)可(ke)以(yi)(yi)做出(chu)某(mou)種讓步的(de)(de)。比如你(ni)發(fa)現手(shou)機在(zai)(zai)你(ni)夜晚睡(shui)覺前(qian)必須充(chong)電(dian)的(de)(de)話，你(ni)也可(ke)以(yi)(yi)在(zai)(zai)睡(shui)前(qian)開始充(chong)電(dian)。問(wen)題的(de)(de)關鍵在(zai)(zai)于(yu)，你(ni)應(ying)該知道(dao)正確(que)的(de)(de)做法(fa)是(shi)什么，并(bing)且不要刻意(yi)按(an)照錯誤的(de)(de)說法(fa)去做。

希望大家努力掌握關于鋰(li)電池的(de)知識和學會正確使(shi)用鋰(li)電池的(de)科學方法，早日在鋰(li)電池的(de)手(shou)機上與流傳已久的(de)錯誤說法和做法告別。
