1、鋰離子電池標稱電壓7V（3.6V），充電截止電壓4.2V（4.1V.根據電芯的廠牌有不同的設計）。（鋰離子電芯規范的說法是：鋰離子二次電池）；

2、對鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)要求（GB/T182872000規范(fan)）：首先(xian)恒流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，即電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)一(yi)定(ding)，而電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)隨著(zhu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)過程(cheng)逐步升高，當電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)端電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)達到(dao)4.2V（4.1V），改(gai)恒流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)為(wei)恒壓(ya)(ya)(ya)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，即電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)一(yi)定(ding)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)根據電(dian)(dian)(dian)(dian)(dian)(dian)芯的飽和(he)程(cheng)度，隨著(zhu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)過程(cheng)的繼續逐步減(jian)小，當減(jian)小到(dao)0.01C時，認為(wei)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)終(zhong)止。（C是(shi)(shi)(shi)(shi)以電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)標稱容量對照電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的一(yi)種表示方法，如電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)(shi)(shi)1000mAh的容量，1C就是(shi)(shi)(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)1000mA，注(zhu)意是(shi)(shi)(shi)(shi)mA而不是(shi)(shi)(shi)(shi)mAh，0.01C就是(shi)(shi)(shi)(shi)10mA。）當然(ran)，規范(fan)的表示方式是(shi)(shi)(shi)(shi)0.01C5A。

3、為(wei)(wei)什么認為(wei)(wei)0.01C為(wei)(wei)充電結(jie)束(shu)：這是(shi)(shi)國家標準(zhun)(zhun)GB/T18287-2000所規定(ding)(ding)的(de)，也(ye)(ye)是(shi)(shi)討論(lun)得出(chu)的(de)。以前大(da)家普遍(bian)以20mA為(wei)(wei)結(jie)束(shu)，郵電部行業標準(zhun)(zhun)YD/T998-1999也(ye)(ye)是(shi)(shi)這樣(yang)規定(ding)(ding)的(de)，即不管電池(chi)容量多大(da)，停止電流都是(shi)(shi)20mA。國標規定(ding)(ding)的(de)0.01C有助于(yu)充電更飽滿，對廠家一(yi)方通過鑒定(ding)(ding)有利(li)。另(ling)外(wai)，國標規定(ding)(ding)了充電時間不超過8小(xiao)時，就(jiu)是(shi)(shi)說(shuo)即使還(huan)沒(mei)有達(da)到(dao)(dao)0.01C，8小(xiao)時到(dao)(dao)了，也(ye)(ye)認為(wei)(wei)充電結(jie)束(shu)。（質量沒(mei)問題的(de)電池(chi)，都應在8小(xiao)時內達(da)到(dao)(dao)0.01C，質量不好的(de)電池(chi)，等下去也(ye)(ye)無意(yi)義）。

4、怎樣(yang)區別(bie)電(dian)池是(shi)4.1V還是(shi)4.2V：消(xiao)費者(zhe)是(shi)無(wu)法(fa)區分的(de)，這(zhe)要看電(dian)芯生產廠家的(de)產品(pin)規格書。有些牌子的(de)電(dian)芯是(shi)4.1V和(he)4.2V通用的(de)，比(bi)如A&TB（東(dong)芝），國內廠家基本是(shi)4.2V，但(dan)也有例外(wai)，比(bi)如天津力神是(shi)4.1V（但(dan)目(mu)前也是(shi)按4.2V了）。

5、把4.1V的(de)(de)電芯(xin)充電到(dao)4.2V會怎么樣(yang)(yang)：會使電池容量(liang)提(ti)高，感覺很(hen)好(hao)用(yong)，待機時間增加，但會減(jian)短電池的(de)(de)使用(yong)壽命。比如原(yuan)來(lai)500次(ci)，減(jian)少(shao)到(dao)300次(ci)。同樣(yang)(yang)道理，把4.2V的(de)(de)電芯(xin)過充，也會減(jian)短壽命。

6、既然電池內(nei)有保護板(ban)，我們是(shi)(shi)否就可以放(fang)心了呢：不是(shi)(shi)，因為保護板(ban)的(de)截止參數是(shi)(shi)4.35V（這還(huan)是(shi)(shi)好的(de)，差的(de)要4.4到4.5V），保護板(ban)是(shi)(shi)應付萬一(yi)的(de)，假如每次都過充，電池也會很快衰(shuai)減的(de)。

7、多大(da)的充(chong)電電流算是合適的：理論上越小對(dui)電池(chi)越有好處。但你(ni)總不能為了一塊電池(chi)充(chong)電等3天吧。

國(guo)標規(gui)定的低倍(bei)率充(chong)電(dian)(dian)是(shi)0.2C（仲裁(cai)充(chong)電(dian)(dian)制式），還(huan)以(yi)上(shang)面的1000mAh容量的電(dian)(dian)池為例，就(jiu)是(shi)200mA，那么我們可以(yi)估計(ji)出(chu)(chu)這只電(dian)(dian)池5個多小(xiao)時(shi)(shi)可以(yi)充(chong)飽。（容量mAh=電(dian)(dian)流mAx時(shi)(shi)間h）經鋸國(guo)家技術監(jian)督部門(men)鑒定鋰電(dian)(dian)容量，是(shi)以(yi)1C的高倍(bei)率充(chong)電(dian)(dian)，以(yi)0.2C的低倍(bei)率放(fang)電(dian)(dian)，以(yi)時(shi)(shi)間計(ji)算出(chu)(chu)容量值，試驗次(ci)(ci)數5次(ci)(ci)，有1次(ci)(ci)容量達(da)到(dao)試驗結束。（就(jiu)是(shi)有5次(ci)(ci)機會，如果第一(yi)(yi)次(ci)(ci)試驗就(jiu)合格了，后(hou)面的4次(ci)(ci)不做）檢測之前允許有一(yi)(yi)次(ci)(ci)預(yu)循環，就(jiu)是(shi)以(yi)1C恒流充(chong)電(dian)(dian)至(zhi)4.2V即停(ting)止，而(er)沒(mei)有后(hou)面的恒壓到(dao)0.01C的過程，更(geng)沒(mei)有14小(xiao)時(shi)(shi)。

8、鋰離子電(dian)(dian)(dian)(dian)池能承受多大(da)的充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)：廠家試驗(yan)時可以很高(gao)，但(dan)國(guo)標高(gao)倍率規(gui)定為(wei)1C，還以上面的電(dian)(dian)(dian)(dian)池為(wei)例(li)，1個多小(xiao)時即可充(chong)滿。這么大(da)的充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)，電(dian)(dian)(dian)(dian)池能承受嗎？對(dui)(dui)于目(mu)前(qian)的鋰離子電(dian)(dian)(dian)(dian)芯，是(shi)小(xiao)意思而已。目(mu)前(qian)沒有(you)對(dui)(dui)充(chong)電(dian)(dian)(dian)(dian)器的國(guo)家標準，所執行(xing)的是(shi)郵電(dian)(dian)(dian)(dian)部(bu)行(xing)業標準YD/T9981999/2，里面規(gui)定了充(chong)電(dian)(dian)(dian)(dian)器的電(dian)(dian)(dian)(dian)流(liu)(liu)不得大(da)于1C。

9、壽(shou)(shou)命(ming)是(shi)(shi)(shi)怎樣規(gui)定的(de)：簡單說是(shi)(shi)(shi)指電池經過(guo)N次(ci)1C充、1C放電后，容量(liang)下降到(dao)70%，此時的(de)N就(jiu)是(shi)(shi)(shi)壽(shou)(shou)命(ming)。并不是(shi)(shi)(shi)說300次(ci)還可以用(yong)，301次(ci)就(jiu)不能用(yong)了。國標規(gui)定壽(shou)(shou)命(ming)不得小于300次(ci)。我們平時使用(yong)的(de)條件(jian)沒(mei)有檢測時這么嚴(yan)酷(ku)，壽(shou)(shou)命(ming)會(hui)更長(chang)。
