1.1 鋰離子電池簡(jian)介

1.1.1 鋰離子電池(Li-ion Batteries)是(shi)鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)發展而(er)來(lai)。在介紹Li-ion之(zhi)前，應(ying)先(xian)介紹鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)。舉例來(lai)講，以前照相機里用的扣式(shi)電(dian)(dian)(dian)池(chi)(chi)(chi)就屬 于鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)。鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)的正極材料是(shi)二(er)氧(yang)化(hua)錳(meng)或(huo)亞硫酰氯，負極是(shi)鋰(li)。電(dian)(dian)(dian)池(chi)(chi)(chi)組裝 完成后電(dian)(dian)(dian)池(chi)(chi)(chi)即有電(dian)(dian)(dian)壓,不需充電(dian)(dian)(dian).這(zhe)種電(dian)(dian)(dian)池(chi)(chi)(chi)也可能(neng)充電(dian)(dian)(dian),但循環性能(neng)不好,在 充放(fang)電(dian)(dian)(dian)循環過程中,容易形成鋰(li)枝晶,造成電(dian)(dian)(dian)池(chi)(chi)(chi)內部(bu)短路,所以一般(ban)情況下這(zhe) 種電(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)禁止充電(dian)(dian)(dian)的。

1.1.2 后來，日本索尼公司發明了以炭材料為負極，以含鋰的化合物作正極，在充放電過程中，沒有金屬鋰存在，只有鋰離子，這就是鋰離子電 池。當對電(dian)池進(jin)行充電(dian)時(shi)，電(dian)池的(de)(de)正(zheng)極(ji)(ji)上有鋰(li)(li)離(li)(li)(li)(li)子生成(cheng)，生成(cheng)的(de)(de)鋰(li)(li)離(li)(li)(li)(li)子經過(guo) 電(dian)解液運(yun)動到(dao)負(fu)極(ji)(ji)。而作為負(fu)極(ji)(ji)的(de)(de)碳(tan)(tan)(tan)呈層狀結(jie)構，它有很多微孔，達到(dao)負(fu)極(ji)(ji) 的(de)(de)鋰(li)(li)離(li)(li)(li)(li)子就嵌入(ru)到(dao)碳(tan)(tan)(tan)層的(de)(de)微孔中，嵌入(ru)的(de)(de)鋰(li)(li)離(li)(li)(li)(li)子越多，充電(dian)容量越高(gao)。同樣， 當對電(dian)池進(jin)行放(fang)電(dian)時(shi)(即我們使用電(dian)池的(de)(de)過(guo)程)，嵌在負(fu)極(ji)(ji)碳(tan)(tan)(tan)層中的(de)(de)鋰(li)(li)離(li)(li)(li)(li)子 脫出， 又(you)運(yun)動回正(zheng)極(ji)(ji)。回正(zheng)極(ji)(ji)的(de)(de)鋰(li)(li)離(li)(li)(li)(li)子越多，放(fang)電(dian)容量越高(gao)。

1.1.3 我們通常所(suo)說的(de)電(dian)(dian)池(chi)容量指(zhi)的(de)就是放電(dian)(dian)容量。在 Li-ion 的(de)充(chong)放電(dian)(dian)過程中，鋰(li)離子處(chu)于從(cong)正(zheng)極(ji)→負極(ji)→正(zheng)極(ji)的(de)運動(dong)狀態。Li-ion Batteries 就像一把搖(yao)(yao)(yao)椅(yi)(yi)(yi)，搖(yao)(yao)(yao)椅(yi)(yi)(yi)的(de)兩(liang)端為電(dian)(dian)池(chi)的(de)兩(liang)極(ji)，而鋰(li)離子就象(xiang)運動(dong)員 一樣在搖(yao)(yao)(yao)椅(yi)(yi)(yi)來回奔跑(pao)。所(suo)以 Li-ion Batteries 又叫搖(yao)(yao)(yao)椅(yi)(yi)(yi)式(shi)電(dian)(dian)池(chi)。

1.3. 鋰離子電池原理

1.3.1 鋰系電池分為鋰電池和鋰離子電(dian)池。目(mu)前手機和筆記(ji)本電(dian)腦使用(yong)

的(de)都是(shi)鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)電(dian)(dian)(dian)池(chi)，通常人(ren)們俗(su)稱(cheng)(cheng)其為(wei)鋰(li)(li)電(dian)(dian)(dian)池(chi)。 手機等(deng) PDA 產品(pin)使用的(de)是(shi) 鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)電(dian)(dian)(dian)池(chi)，而(er)真正(zheng)(zheng)(zheng)的(de)鋰(li)(li)電(dian)(dian)(dian)池(chi)由于危險(xian)性大，沒有(you)應用于日(ri)常電(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)產品(pin)。 鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)電(dian)(dian)(dian)池(chi)以碳素材(cai)料為(wei)負極(ji)(ji)，以含鋰(li)(li)的(de)化(hua)合(he)物(wu)作正(zheng)(zheng)(zheng)極(ji)(ji)，沒有(you)金屬鋰(li)(li)存 在(zai)，只有(you)鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)，這(zhe)就是(shi)鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)電(dian)(dian)(dian)池(chi)。鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)電(dian)(dian)(dian)池(chi)是(shi)指以鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)嵌(qian)入(ru)(ru)(ru)(ru)化(hua)合(he)物(wu) 為(wei)正(zheng)(zheng)(zheng)極(ji)(ji)材(cai)料電(dian)(dian)(dian)池(chi)的(de)總稱(cheng)(cheng)。鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)電(dian)(dian)(dian)池(chi)的(de)充放(fang)電(dian)(dian)(dian)過程(cheng)，就是(shi)鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)的(de)嵌(qian)入(ru)(ru)(ru)(ru)和脫(tuo) 嵌(qian)過程(cheng)。在(zai)鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)的(de)嵌(qian)入(ru)(ru)(ru)(ru)和脫(tuo)嵌(qian)過程(cheng)中，同時(shi)伴(ban)隨著與鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)等(deng)當(dang)量電(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)的(de) 嵌(qian)入(ru)(ru)(ru)(ru)和脫(tuo)嵌(qian)(習慣(guan)上(shang)正(zheng)(zheng)(zheng)極(ji)(ji)用嵌(qian)入(ru)(ru)(ru)(ru)或脫(tuo)嵌(qian)表示(shi)，而(er)負極(ji)(ji)用插入(ru)(ru)(ru)(ru)或脫(tuo)插表示(shi))。 在(zai)充放(fang)電(dian)(dian)(dian)過程(cheng)中，鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)(zi)在(zai)正(zheng)(zheng)(zheng)、負極(ji)(ji)之(zhi)間往返嵌(qian)入(ru)(ru)(ru)(ru)/脫(tuo)嵌(qian)和插入(ru)(ru)(ru)(ru)/脫(tuo)插，被形 象(xiang)地稱(cheng)(cheng)為(wei)“搖椅電(dian)(dian)(dian)池(chi)”。

1.3.2 鋰離子電池能量密度大，平均(jun)輸出電壓(ya)高。自放電小(xiao)，每月在

10%以下。沒(mei)有記憶效應。工作溫度范圍(wei)寬為-20℃～60℃。循(xun)環性能(neng)優越、 可快速充(chong)放電(dian)、充(chong)電(dian)效率高達 100%，而且輸出(chu)功(gong)率大(da)。使(shi)用(yong)壽命長。沒(mei)有 環境污染(ran)，被稱為綠色(se)電(dian)池。

1.3.3 充電是電池重(zhong)(zhong)復使(shi)用的(de)(de)重(zhong)(zhong)要步(bu)驟，鋰離子電池的(de)(de)充電過程(cheng)分(fen)

為兩個(ge)階(jie)段(duan)：恒(heng)流快充階(jie)段(duan)(指示燈呈(cheng)紅色(se)或黃色(se))和恒(heng)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)流遞減階(jie)段(duan)(指 示燈呈(cheng)綠色(se))。恒(heng)流快充階(jie)段(duan)，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)逐(zhu)步(bu)升高到電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的標準電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，隨(sui)后(hou) 在控制芯片下轉入恒(heng)壓(ya)(ya)階(jie)段(duan)，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)再升高以確保不(bu)會過充，電(dian)(dian)(dian)(dian)(dian)(dian)流則隨(sui)著電(dian)(dian)(dian)(dian)(dian)(dian) 池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)的上升逐(zhu)步(bu)減弱到 0，而最終完成充電(dian)(dian)(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)統(tong)計芯片通(tong)過記(ji)錄放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian) 曲線可以抽樣(yang)計算出電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)。鋰離(li)(li)子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)在多次(ci)使用(yong)后(hou)，放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)曲線會發(fa) 生(sheng)改(gai)變，鋰離(li)(li)子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)雖然不(bu)存(cun)在記(ji)憶效應，但是充電(dian)(dian)(dian)(dian)(dian)(dian)不(bu)當(dang)會嚴(yan)重影響電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)性(xing) 能(neng)。

鋰離(li)子(zi)(zi)電池(chi)過(guo)(guo)度(du)充放電會對(dui)正負(fu)(fu)極(ji)造成永久性(xing)損壞。過(guo)(guo)度(du)放電導(dao)致負(fu)(fu)極(ji) 碳片層結構(gou)出現塌陷，而塌陷會造成充電過(guo)(guo)程中鋰離(li)子(zi)(zi)無法插入(ru);過(guo)(guo)度(du)充電 使(shi)過(guo)(guo)多的鋰離(li)子(zi)(zi)嵌入(ru)負(fu)(fu)極(ji)碳結構(gou)，而造成其中部分(fen)鋰離(li)子(zi)(zi)再(zai)也無法釋放出

1.3.4 充電(dian)(dian)量等于充電(dian)(dian)電(dian)(dian)流乘以充電(dian)(dian)時間，在充電(dian)(dian)控(kong)制電(dian)(dian)壓一定

的(de)情況下，充(chong)電電流越大(充(chong)電速(su)(su)度(du)越快)，充(chong)電電量越小。電池充(chong)電速(su)(su)度(du) 過快和終止電壓控制點不(bu)當，同樣會造成電池容量不(bu)足(zu)，實際是電池的(de)部分 電極活性(xing)物質(zhi)沒有得到充(chong)分反(fan)應就停止充(chong)電，這(zhe)種充(chong)電不(bu)足(zu)的(de)現象隨(sui)著循環 次數的(de)增加(jia)而加(jia)劇。

1.4. 鋰離子電池的種(zhong)類(lei)

1.4.1 不可充電的(de)鋰電池(chi)有多種，目前常(chang)用的(de)有鋰-二氧化錳電池(chi)、鋰

—亞硫酰氯電(dian)池(chi)及(ji)鋰和其它化合物電(dian)池(chi)。

1)　鋰-二氧化(hua)錳電池(Li　MnO2)

鋰(li)-二氧化(hua)錳電(dian)(dian)池(chi)是一(yi)種以(yi)鋰(li)為(wei)(wei)陽極、以(yi)二氧化(hua)錳為(wei)(wei)陰(yin)極，并采用有機 電(dian)(dian)解液(ye)的(de)(de)一(yi)次(ci)性電(dian)(dian)池(chi)。該電(dian)(dian)池(chi)的(de)(de)主要特點是電(dian)(dian)池(chi)電(dian)(dian)壓高，額定電(dian)(dian)壓為(wei)(wei) 3V(是 一(yi)般堿(jian)性電(dian)(dian)池(chi)的(de)(de) 2 倍);終止放(fang)電(dian)(dian)電(dian)(dian)壓為(wei)(wei) 2V;比能(neng)量大(見上面舉的(de)(de)例子); 放(fang)電(dian)(dian)電(dian)(dian)壓穩定可靠;有較好的(de)(de)儲存性能(neng)(儲存時間 3 年以(yi)上)、自放(fang)電(dian)(dian)率低(年 自放(fang)電(dian)(dian)率≤2%);工(gong)作溫度(du)范圍-20℃～+60℃。

2)可充電(dian)鋰離子電(dian)池

可充(chong)(chong)電(dian)(dian)(dian)鋰離子電(dian)(dian)(dian)池(chi)(chi)是(shi)目(mu)前(qian)手機中(zhong)應(ying)用最(zui)廣泛的電(dian)(dian)(dian)池(chi)(chi)，但(dan)它較為“嬌氣”， 在(zai)使用中(zhong)不可過(guo)充(chong)(chong)、過(guo)放(fang)(會損(sun)壞電(dian)(dian)(dian)池(chi)(chi)或使之報廢)。因此，在(zai)電(dian)(dian)(dian)池(chi)(chi)上(shang)有保護 元(yuan)器(qi)(qi)件(jian)(jian)或保護電(dian)(dian)(dian)路以(yi)防止(zhi)昂貴的電(dian)(dian)(dian)池(chi)(chi)損(sun)壞。 鋰離子電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)要求很高(gao)，要 保證(zheng)(zheng)終止(zhi)電(dian)(dian)(dian)壓(ya)精度(du)在(zai) 1%之內，目(mu)前(qian)各(ge)大半導(dao)體器(qi)(qi)件(jian)(jian)廠已開發出多種鋰離子 電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)的 IC，以(yi)保證(zheng)(zheng)安全、可靠、快速地充(chong)(chong)電(dian)(dian)(dian)。

1.4.2 根據鋰離子電池所用電解(jie)質材料不同，鋰離子電池可以分(fen)為(wei)液(ye)

態(tai)(tai)(tai)鋰離子(zi)電(dian)(dian)池(chi)(lithium ion battery, 簡稱為 LIB)和聚(ju)(ju)合(he)物鋰離子(zi)電(dian)(dian)池(chi)(p olymer lithium ion battery, 簡稱為 LIP)兩大類。聚(ju)(ju)合(he)物鋰離子(zi)電(dian)(dian)池(chi)所 用的(de)(de)正負極材料(liao)與液態(tai)(tai)(tai)鋰離子(zi)都(dou)是(shi)相同(tong)的(de)(de)，電(dian)(dian)池(chi)的(de)(de)工(gong)作原理也(ye)基(ji)本一(yi)致。 它們的(de)(de)主要區別在于電(dian)(dian)解(jie)質(zhi)的(de)(de)不同(tong), 液態(tai)(tai)(tai)鋰離子(zi)電(dian)(dian)池(chi)使(shi)用的(de)(de)是(shi)液體(ti)電(dian)(dian)解(jie)質(zhi), 而聚(ju)(ju)合(he)物鋰離子(zi)電(dian)(dian)池(chi)則以(yi)固(gu)體(ti)聚(ju)(ju)合(he)物電(dian)(dian)解(jie)質(zhi)來代替, 這(zhe)種(zhong)聚(ju)(ju)合(he)物可以(yi)是(shi) “干態(tai)(tai)(tai)”的(de)(de),也(ye)可以(yi)是(shi)“膠態(tai)(tai)(tai)”的(de)(de),目前大部(bu)分采用聚(ju)(ju)合(he)物膠體(ti)電(dian)(dian)解(jie)質(zhi)。聚(ju)(ju) 合(he)物鋰離子(zi)電(dian)(dian)池(chi)可分為三(san)類：

(1)固體聚合物(wu)(wu)電(dian)(dian)解質(zhi)鋰離子(zi)電(dian)(dian)池(chi)。電(dian)(dian)解質(zhi)為(wei)聚合物(wu)(wu)與(yu)鹽的混合物(wu)(wu)， 這種電(dian)(dian)池(chi)在常溫(wen)下的離子(zi)電(dian)(dian)導率低(di)，適(shi)于高溫(wen)使用。

(2)凝膠聚(ju)合物(wu)(wu)電(dian)(dian)(dian)解(jie)(jie)質(zhi)鋰(li)(li)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)。即在固體(ti)(ti)聚(ju)合物(wu)(wu)電(dian)(dian)(dian)解(jie)(jie)質(zhi)中(zhong)加入增(zeng) 塑(su)劑(ji)等(deng)添加劑(ji)，從而(er)提(ti)高(gao)(gao)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)導率，使電(dian)(dian)(dian)池(chi)(chi)(chi)可在常(chang)溫下使用。 (3)聚(ju)合物(wu)(wu)正(zheng)極材(cai)料的(de)(de)鋰(li)(li)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)。采(cai)用導電(dian)(dian)(dian)聚(ju)合物(wu)(wu)作(zuo)(zuo)為(wei)正(zheng)極材(cai)料， 其(qi)比(bi)能量(liang)(liang)是(shi)現有(you)鋰(li)(li)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de) 3 倍(bei)，是(shi)最新一代的(de)(de)鋰(li)(li)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)。由于用固 體(ti)(ti)電(dian)(dian)(dian)解(jie)(jie)質(zhi)代替了液(ye)(ye)體(ti)(ti)電(dian)(dian)(dian)解(jie)(jie)質(zhi),與(yu)液(ye)(ye)態鋰(li)(li)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)相比(bi)，聚(ju)合物(wu)(wu)鋰(li)(li)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)具 有(you)可薄形化(hua)、任(ren)意面積化(hua)與(yu)任(ren)意形狀化(hua)等(deng)優(you)點，也不會產生漏液(ye)(ye)與(yu)燃燒爆 炸(zha)等(deng)安全上的(de)(de)問題，因此可以用鋁塑(su)復合薄膜(mo)制造電(dian)(dian)(dian)池(chi)(chi)(chi)外殼(ke)，從而(er)可以提(ti) 高(gao)(gao)整個電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)比(bi)容量(liang)(liang);聚(ju)合物(wu)(wu)鋰(li)(li)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)還可以采(cai)用高(gao)(gao)分子(zi)(zi)作(zuo)(zuo)正(zheng)極材(cai)料， 其(qi)質(zhi)量(liang)(liang)比(bi)能量(liang)(liang)將會比(bi)目前的(de)(de)液(ye)(ye)態鋰(li)(li)離(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)提(ti)高(gao)(gao) 50%以上。

此(ci)外,聚合物鋰離(li)子(zi)電(dian)池在工作(zuo)電(dian)壓(ya)、充放(fang)電(dian)循環(huan)壽命(ming)等方面都比鋰離(li)子(zi)電(dian)池有所提(ti)高(gao)。

基(ji)于以上優(you)點，聚合物鋰(li)離(li)(li)子(zi)(zi)電(dian)池被譽為下一代(dai)(dai)鋰(li)離(li)(li)子(zi)(zi)電(dian)池。 聚合物鋰(li)離(li)(li)子(zi)(zi)(Lithium ion polymer)電(dian)池，具(ju)有更高能(neng)量(liang)密度、小型化(hua)、薄型化(hua)、 輕量(liang)化(hua)、高安(an)全性、長循(xun)環壽命與低成本(ben)的新(xin)型電(dian)池。因(yin)此，在未(wei)來 2～3 年內，聚合物鋰(li)電(dian)池取代(dai)(dai)鋰(li)離(li)(li)子(zi)(zi)電(dian)池市場的份額將達(da) 50%。

1.4.3 當前(qian)手機已(yi)被廣泛(fan)使用，早期的(de)手機中多(duo)使用鎳氫電池，但靈

1.5. 鋰離子(zi)電(dian)池優缺點

1.5.1 鋰(li)離(li)子(zi)電池具有以下優(you)點：

1. 電(dian)(dian)壓高(gao)，單體電(dian)(dian)池(chi)的工作電(dian)(dian)壓高(gao)達 3.6-3.9V，是 Ni-Cd、 Ni-H 電(dian)(dian)池(chi)的 3 倍(bei)

2. 比(bi)能量(liang)大，目前能達到的實際比(bi)能量(liang)為 100-125Wh/kg 和(he) 240-300Wh/L(2 倍于(yu)(yu) Ni-Cd，1.5 倍于(yu)(yu) Ni-MH),未(wei)來(lai)隨著技(ji)術發(fa)展, 比(bi)能量(liang)可(ke)高達 150Wh/kg 和(he) 400 Wh/L

3. 循(xun)環壽命長(chang),一般均可達到 500 次(ci)以(yi)上,甚至 1000 次(ci)以(yi)上.對于小電 流放電的電器,電池的使用期限 將倍增電器的競爭力(li).

4. 安(an)全性能好,無(wu)公(gong)害,無(wu)記憶效(xiao)應(ying)(ying).作為Li-ion前身的(de)(de)鋰(li)電(dian)池(chi),因金(jin)屬 鋰(li)易形(xing)成枝晶發(fa)生短路(lu),縮(suo)減了(le)其應(ying)(ying)用領域(yu)：Li-ion中不(bu)含鎘、鉛(qian)、汞等對 環境有污染的(de)(de)元素(su)：部分工藝(如燒(shao)結式)的(de)(de)Ni-Cd電(dian)池(chi)存在(zai)的(de)(de)一(yi)大弊(bi)病(bing)為 “記憶效(xiao)應(ying)(ying)”，嚴重束縛電(dian)池(chi)的(de)(de)使(shi)用，但Li-ion根(gen)本不(bu)存在(zai)這方面(mian)的(de)(de)問題(ti)。

5. 自(zi)放電(dian)小，室溫下充滿電(dian)的(de) Li-ion 儲存 1 個月后的(de)自(zi)放電(dian)率為 10%左(zuo)右，大大低于(yu) Ni-Cd 的(de) 25-30%，Ni、MH 的(de) 30-35%。

6. 可(ke)快速充(chong)放(fang)電，1C 充(chong)電是容量可(ke)以達到標稱容量的 80%以上(shang)。

7. 工作(zuo)溫(wen)(wen)度范(fan)圍高，工作(zuo)溫(wen)(wen)度為-25~45_C，隨著電(dian)解質和正(zheng)極的 改進，期望能擴寬到-40~70_C。

1.5.2.鋰離(li)子電池也存在(zai)著一定的(de)缺點

1. 電池成本較(jiao)高。 主要(yao)表現在正極材料 LiCoO2 的價(jia)格高 (Co 的資(zi)源(yuan)較(jiao)少)，電解質體(ti)系提純困難。

2. 不能(neng)大(da)電流放電。 由于(yu)有機電解質體系等(deng)原(yuan)因，電池內(nei)阻相對

其他(ta)類(lei)電(dian)池大。故(gu)要求較小的(de)(de)放電(dian)電(dian)流密度，一般放電(dian)電(dian)流在 0.5C 以下， 只適合(he)于中小電(dian)流的(de)(de)電(dian)器使用。

3. 需要保護線路控制 。

A. 過充保護：電池過充將(jiang)破壞正極結構而影(ying)響(xiang)性能和壽命;同時(shi)過充 電使電解(jie)(jie)液分(fen)解(jie)(jie)，內部壓(ya)力過高而導致漏(lou)液等(deng)問(wen)題;故必須(xu)在 4.1V-4.2V 的 恒壓(ya)下(xia)充電;

B. 過(guo)(guo)放保護(hu)(hu)：過(guo)(guo)放會導致活性物質的恢復(fu)困難，故也(ye)需要(yao)有保護(hu)(hu)線路 控制。

4)充電電池定義

充(chong)電(dian)電(dian)池(chi)(chi)又稱(cheng)：蓄電(dian)池(chi)(chi)、二(er)次電(dian)池(chi)(chi)，是可以反復充(chong)電(dian)使用(yong)(yong)的(de)電(dian)池(chi)(chi)。常見(jian) 的(de)有：鉛酸電(dian)池(chi)(chi)(用(yong)(yong)于(yu)汽(qi)車(che)時(shi)，俗(su)稱(cheng)“電(dian)瓶”)、鎘鎳電(dian)池(chi)(chi)、氫鎳電(dian)池(chi)(chi)、鋰 離子電(dian)池(chi)(chi)。

5)電池的額定容量

電(dian)池(chi)的額定(ding)容(rong)(rong)量指(zhi)在一定(ding)放電(dian)條件下，電(dian)池(chi)放電(dian)至截止電(dian)壓時放出的電(dian) 量。IEC 標(biao)準(zhun)規(gui)定(ding)鎳鎘和鎳氫電(dian)池(chi)在 20_5℃環境(jing)下，以(yi) 0.1C 充電(dian) 16 小時 后以(yi) 0.2C 放電(dian)至 1.0V 時所(suo)放出的電(dian)量為電(dian)池(chi)的額定(ding)容(rong)(rong)量。單(dan)位有 Ah, mAh (1Ah=1000mAh)

1.6. 如何正(zheng)確(que)使用(yong)鋰離子(zi)電(dian)池(chi).

正確使(shi)用鋰離子電池應(ying)注意以(yi)下幾點：

避免(mian)在嚴酷條件下使(shi)用，如：高溫、高濕度(du)、夏日陽光下長時間暴(bao)曬(shai)等， 避免(mian)將電(dian)池投入火中;

裝、拆電(dian)池(chi)時，應確保用(yong)電(dian)器具(ju)處于(yu)電(dian)源關(guan)閉狀(zhuang)態(tai);使用(yong)溫度應保持在 -20~55℃之間;

避免(mian)將電(dian)池長時間(jian)“存放”在停止使(shi)用的用電(dian)器具中;

1.6.1.如何為新電池充(chong)電,

在(zai)使用鋰電(dian)(dian)池(chi)中應注意的(de)是，電(dian)(dian)池(chi)放(fang)置(zhi)一段時間后(hou)則進(jin)入休(xiu)眠狀態，此(ci) 時容(rong)量(liang)低于(yu)正常值，使用時間亦隨之縮短。但鋰電(dian)(dian)池(chi)很(hen)容(rong)易激活(huo)，只要經過 3—5次正常的(de)充放(fang)電(dian)(dian)循環(huan)就可激活(huo)電(dian)(dian)池(chi)，恢(hui)復正常容(rong)量(liang)。由于(yu)鋰電(dian)(dian)池(chi)本身 的(de)特性，決定了它幾乎沒有記憶效應。因此(ci)用戶手機中的(de)新(xin)鋰電(dian)(dian)池(chi)在(zai)激活(huo)過

程中，是不需要特別的方法和(he)設備的。不僅(jin)理論(lun)上是如此(ci)，從(cong)我自己的實踐

來看(kan)，從一開始就(jiu)采用標準方(fang)法充(chong)電這種“自然(ran)激活”方(fang)式(shi)是最(zui)好的。

對(dui)于鋰(li)電(dian)(dian)(dian)池(chi)的(de)(de)(de)“激活”問題，眾(zhong)多的(de)(de)(de)說(shuo)法(fa)是(shi)：充(chong)電(dian)(dian)(dian)時(shi)間(jian)一(yi)定要超過 12 小(xiao)(xiao)時(shi)，反(fan)復做(zuo)三(san)次，以便激活電(dian)(dian)(dian)池(chi)。這(zhe)種(zhong)“前三(san)次充(chong)電(dian)(dian)(dian)要充(chong) 12 小(xiao)(xiao)時(shi)以上” 的(de)(de)(de)說(shuo)法(fa)，明顯(xian)是(shi)從鎳電(dian)(dian)(dian)池(chi)(如鎳鎘和鎳氫)延續(xu)下來的(de)(de)(de)說(shuo)法(fa)。所(suo)以這(zhe)種(zhong)說(shuo)法(fa)， 可(ke)以說(shuo)一(yi)開始就(jiu)是(shi)誤傳。鋰(li)電(dian)(dian)(dian)池(chi)和鎳電(dian)(dian)(dian)池(chi)的(de)(de)(de)充(chong)放電(dian)(dian)(dian)特性有非常大(da)的(de)(de)(de)區(qu)別，而(er) 且(qie)可(ke)以非常明確的(de)(de)(de)告(gao)訴(su)大(da)家(jia)，在所(suo)查(cha)閱過的(de)(de)(de)嚴肅的(de)(de)(de)且(qie)正式的(de)(de)(de)技術資(zi)料中都(dou)強 調(diao)過充(chong)和過放電(dian)(dian)(dian)會對(dui)鋰(li)電(dian)(dian)(dian)池(chi)、特別是(shi)液體鋰(li)離子電(dian)(dian)(dian)池(chi)造成巨大(da)的(de)(de)(de)傷害(hai)。因而(er) 充(chong)電(dian)(dian)(dian)最好(hao)按照標(biao)準(zhun)時(shi)間(jian)和標(biao)準(zhun)方(fang)法(fa)充(chong)電(dian)(dian)(dian)，特別是(shi)不要進行超過 12 個小(xiao)(xiao)時(shi)的(de)(de)(de) 超長充(chong)電(dian)(dian)(dian)。

此外(wai)，鋰(li)(li)電(dian)(dian)池(chi)或充(chong)(chong)(chong)電(dian)(dian)器(qi)在(zai)電(dian)(dian)池(chi)充(chong)(chong)(chong)滿后(hou)都(dou)會自動停充(chong)(chong)(chong)，并不存(cun)在(zai)鎳電(dian)(dian)充(chong)(chong)(chong)電(dian)(dian) 器(qi)所謂的持續 10 幾(ji)小(xiao)時的“涓流”充(chong)(chong)(chong)電(dian)(dian)。也就是說，如果你的鋰(li)(li)電(dian)(dian)池(chi)在(zai)充(chong)(chong)(chong) 滿后(hou)，放在(zai)充(chong)(chong)(chong)電(dian)(dian)器(qi)上也是白(bai)充(chong)(chong)(chong)。而我們誰都(dou)無(wu)法(fa)保證電(dian)(dian)池(chi)的充(chong)(chong)(chong)放電(dian)(dian)保護電(dian)(dian)路(lu)

8 / 18

的特性永不變(bian)化(hua)和質(zhi)量的萬(wan)無(wu)一失，所以(yi)你的電池將長期處(chu)在危險的邊緣徘 徊。這(zhe)也是我們反(fan)對長充電的另(ling)一個理由。

此外，不可忽視的另(ling)外一個方(fang)面(mian)就是鋰電池同(tong)樣(yang)(yang)也不適(shi)合過(guo)放電，過(guo)放 電對鋰電池同(tong)樣(yang)(yang)也很不利。

1.6.2、正常使用中應該何(he)時開始充電

經常可(ke)以(yi)見到這種說法，因為充放(fang)電的次數是(shi)(shi)有限的，所以(yi)應該將手機 電池的電盡可(ke)能(neng)用光再(zai)充電。但是(shi)(shi)我找(zhao)到一個(ge)關于鋰(li)離子(zi)電池充放(fang)電循(xun)環(huan)的 實驗表，關于循(xun)環(huan)壽命的數據列(lie)出(chu)如下:

循環(huan)壽命 (10%DOD):>1000 次

循環(huan)壽命 (100%DOD):>200 次(ci)

 DOD 是放電深度的英文縮寫。從表中可見，可充電次數和放電深度 有關，10%DOD 時的循環壽命要比 100%DOD 的要長很多。當然如果折合到實 際充電的相對總容量：10%*1000=100，100%*200=200，后者的完全充放電還 是要比較好一些，但前面網友的那個說法要做一些修正：在正常情況下，你 應該有保留地按照電池剩余電量用完再充的原則充電，但假如你的電池在你 預計第 2 天不可能堅持整個白天的時候，就應該及時開始充電，當然你如果 愿意背著充電器到辦公室又當別論。

電(dian)池(chi)剩余電(dian)量用(yong)完(wan)再充(chong)的(de)原則并不是(shi)(shi)要(yao)你走(zou)向極端。和長充(chong)電(dian)一樣流傳 甚廣(guang)的(de)一個(ge)(ge)說法，就是(shi)(shi)“盡量把(ba)電(dian)池(chi)的(de)電(dian)量用(yong)完(wan)”。這(zhe)種做(zuo)法其實只(zhi)是(shi)(shi)鎳電(dian) 池(chi)上的(de)做(zuo)法，目的(de)是(shi)(shi)避免記憶效應發生，不幸的(de)是(shi)(shi)它(ta)也在鋰電(dian)池(chi)上流傳之今。 曾(ceng)經有(you)人因為手機(ji)電(dian)池(chi)電(dian)量過(guo)(guo)低(di)的(de)警告出現(xian)后(hou)，仍然不充(chong)電(dian)繼續使用(yong)一直用(yong) 到自動關(guan)機(ji)的(de)例子。結果(guo)這(zhe)個(ge)(ge)例子中的(de)手機(ji)在后(hou)來的(de)充(chong)電(dian)及開機(ji)中均無反 應，不得(de)不送客服檢(jian)修。這(zhe)其實就是(shi)(shi)由于(yu)電(dian)池(chi)因過(guo)(guo)度(du)放(fang)電(dian)而(er)導(dao)致電(dian)壓過(guo)(guo)低(di)， 以至于(yu)不具備正常的(de)充(chong)電(dian)和開機(ji)條(tiao)件(jian)造成的(de)。
