1.1 鋰(li)離子電池簡介

1.1.1 鋰離子電池(Li-ion Batteries)是(shi)(shi)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)發展而來(lai)。在(zai)介紹(shao)Li-ion之前，應(ying)先(xian)介紹(shao)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。舉例來(lai)講(jiang)，以(yi)前照(zhao)相機里用的(de)扣式電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)就(jiu)屬 于鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)正極(ji)材(cai)料是(shi)(shi)二氧化錳或亞硫酰氯(lv)，負極(ji)是(shi)(shi)鋰。電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)組(zu)裝(zhuang) 完成后電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)即有電(dian)(dian)(dian)(dian)壓(ya),不需充電(dian)(dian)(dian)(dian).這(zhe)(zhe)種電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)也可能充電(dian)(dian)(dian)(dian),但(dan)循環(huan)(huan)性能不好,在(zai) 充放電(dian)(dian)(dian)(dian)循環(huan)(huan)過程(cheng)中(zhong),容(rong)易形成鋰枝晶,造成電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)內部短路,所(suo)以(yi)一般情況下這(zhe)(zhe) 種電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)(shi)禁止充電(dian)(dian)(dian)(dian)的(de)。

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，電(dian)池的(de)(de)正(zheng)(zheng)(zheng)極上(shang)有鋰(li)離(li)(li)子(zi)(zi)生成，生成的(de)(de)鋰(li)離(li)(li)子(zi)(zi)經過 電(dian)解液運動到負極。而作為負極的(de)(de)碳(tan)呈層狀結構，它有很多微孔，達到負極 的(de)(de)鋰(li)離(li)(li)子(zi)(zi)就嵌(qian)入到碳(tan)層的(de)(de)微孔中(zhong)，嵌(qian)入的(de)(de)鋰(li)離(li)(li)子(zi)(zi)越多，充電(dian)容量越高(gao)(gao)。同樣(yang)， 當對電(dian)池進(jin)行放電(dian)時(即我們使用(yong)電(dian)池的(de)(de)過程)，嵌(qian)在負極碳(tan)層中(zhong)的(de)(de)鋰(li)離(li)(li)子(zi)(zi) 脫出， 又運動回正(zheng)(zheng)(zheng)極。回正(zheng)(zheng)(zheng)極的(de)(de)鋰(li)離(li)(li)子(zi)(zi)越多，放電(dian)容量越高(gao)(gao)。

1.1.3 我們通(tong)常所說的(de)(de)電(dian)(dian)池容(rong)量指的(de)(de)就是(shi)放(fang)電(dian)(dian)容(rong)量。在 Li-ion 的(de)(de)充放(fang)電(dian)(dian)過程中，鋰(li)離子處(chu)于從正極→負極→正極的(de)(de)運動狀態。Li-ion Batteries 就像一把(ba)搖椅(yi)(yi)，搖椅(yi)(yi)的(de)(de)兩(liang)端為電(dian)(dian)池的(de)(de)兩(liang)極，而鋰(li)離子就象運動員 一樣在搖椅(yi)(yi)來回奔跑。所以 Li-ion Batteries 又叫搖椅(yi)(yi)式電(dian)(dian)池。

1.3. 鋰離(li)子電(dian)池原理

1.3.1 鋰系電池分為鋰電池和鋰離(li)子電池。目前手機和筆記本電腦使用

的(de)(de)都(dou)是(shi)(shi)鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)電池，通常(chang)人(ren)們俗稱(cheng)其為(wei)鋰(li)(li)(li)(li)電池。 手機等 PDA 產(chan)(chan)品(pin)使用的(de)(de)是(shi)(shi) 鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)電池，而(er)真(zhen)正(zheng)的(de)(de)鋰(li)(li)(li)(li)電池由于(yu)危險性大，沒有應(ying)用于(yu)日常(chang)電子(zi)(zi)(zi)(zi)產(chan)(chan)品(pin)。 鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)電池以(yi)(yi)碳素材料(liao)為(wei)負極(ji)，以(yi)(yi)含鋰(li)(li)(li)(li)的(de)(de)化(hua)合物作正(zheng)極(ji)，沒有金屬鋰(li)(li)(li)(li)存 在，只有鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)，這就是(shi)(shi)鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)電池。鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)電池是(shi)(shi)指以(yi)(yi)鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)嵌入(ru)(ru)化(hua)合物 為(wei)正(zheng)極(ji)材料(liao)電池的(de)(de)總稱(cheng)。鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)電池的(de)(de)充放(fang)電過(guo)(guo)程(cheng)，就是(shi)(shi)鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)的(de)(de)嵌入(ru)(ru)和(he)脫(tuo) 嵌過(guo)(guo)程(cheng)。在鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)的(de)(de)嵌入(ru)(ru)和(he)脫(tuo)嵌過(guo)(guo)程(cheng)中(zhong)，同時伴隨著與鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)等當(dang)量電子(zi)(zi)(zi)(zi)的(de)(de) 嵌入(ru)(ru)和(he)脫(tuo)嵌(習慣上(shang)正(zheng)極(ji)用嵌入(ru)(ru)或(huo)脫(tuo)嵌表(biao)示，而(er)負極(ji)用插(cha)入(ru)(ru)或(huo)脫(tuo)插(cha)表(biao)示)。 在充放(fang)電過(guo)(guo)程(cheng)中(zhong)，鋰(li)(li)(li)(li)離(li)(li)子(zi)(zi)(zi)(zi)在正(zheng)、負極(ji)之間(jian)往返嵌入(ru)(ru)/脫(tuo)嵌和(he)插(cha)入(ru)(ru)/脫(tuo)插(cha)，被形 象地(di)稱(cheng)為(wei)“搖椅電池”。

1.3.2 鋰離子電(dian)池能量(liang)密(mi)度大(da)，平均輸出(chu)電(dian)壓(ya)高。自放電(dian)小，每月在(zai)

10%以下(xia)。沒有記憶效應。工作溫(wen)度(du)范圍寬為-20℃～60℃。循環性能(neng)優越、 可快(kuai)速充放(fang)電(dian)(dian)、充電(dian)(dian)效率高達(da) 100%，而(er)且輸出功率大(da)。使用(yong)壽命(ming)長。沒有 環境污染(ran)，被稱為綠色電(dian)(dian)池(chi)。

1.3.3 充電是電池重(zhong)復(fu)使用的(de)重(zhong)要步(bu)驟，鋰離子(zi)電池的(de)充電過程分(fen)

為(wei)兩個階段(duan)(duan)：恒(heng)流(liu)快(kuai)充(chong)階段(duan)(duan)(指(zhi)示燈呈(cheng)紅色(se)或黃色(se))和(he)恒(heng)壓電(dian)(dian)(dian)流(liu)遞減階段(duan)(duan)(指(zhi) 示燈呈(cheng)綠(lv)色(se))。恒(heng)流(liu)快(kuai)充(chong)階段(duan)(duan)，電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓逐步(bu)升高到(dao)電(dian)(dian)(dian)池(chi)的(de)標準(zhun)電(dian)(dian)(dian)壓，隨后(hou) 在(zai)控制芯(xin)片下(xia)轉入恒(heng)壓階段(duan)(duan)，電(dian)(dian)(dian)壓不(bu)(bu)再升高以(yi)確保不(bu)(bu)會過充(chong)，電(dian)(dian)(dian)流(liu)則隨著(zhu)電(dian)(dian)(dian) 池(chi)電(dian)(dian)(dian)量(liang)的(de)上升逐步(bu)減弱到(dao) 0，而最終完成(cheng)充(chong)電(dian)(dian)(dian)。電(dian)(dian)(dian)量(liang)統(tong)計芯(xin)片通過記(ji)錄放(fang)電(dian)(dian)(dian) 曲線可(ke)以(yi)抽樣(yang)計算出電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)量(liang)。鋰離子電(dian)(dian)(dian)池(chi)在(zai)多次(ci)使用(yong)后(hou)，放(fang)電(dian)(dian)(dian)曲線會發 生改(gai)變，鋰離子電(dian)(dian)(dian)池(chi)雖然不(bu)(bu)存在(zai)記(ji)憶效應(ying)，但是充(chong)電(dian)(dian)(dian)不(bu)(bu)當會嚴重影(ying)響電(dian)(dian)(dian)池(chi)性 能。

鋰離子電(dian)池過(guo)度(du)(du)充放(fang)電(dian)會(hui)對正負(fu)極(ji)造成永久(jiu)性損壞。過(guo)度(du)(du)放(fang)電(dian)導(dao)致(zhi)負(fu)極(ji) 碳片(pian)層結構(gou)出現塌陷，而塌陷會(hui)造成充電(dian)過(guo)程中(zhong)鋰離子無(wu)(wu)法插入;過(guo)度(du)(du)充電(dian) 使過(guo)多的鋰離子嵌(qian)入負(fu)極(ji)碳結構(gou)，而造成其中(zhong)部分鋰離子再也無(wu)(wu)法釋(shi)放(fang)出

1.3.4 充(chong)(chong)電量等于(yu)充(chong)(chong)電電流乘以充(chong)(chong)電時間，在充(chong)(chong)電控(kong)制電壓一定

的情(qing)況下，充(chong)電(dian)電(dian)流越大(充(chong)電(dian)速(su)(su)度越快)，充(chong)電(dian)電(dian)量越小。電(dian)池(chi)充(chong)電(dian)速(su)(su)度 過(guo)快和(he)終止電(dian)壓(ya)控(kong)制(zhi)點(dian)不當，同樣(yang)會造成電(dian)池(chi)容量不足(zu)，實際是電(dian)池(chi)的部分 電(dian)極活(huo)性物質沒有得到充(chong)分反應就停止充(chong)電(dian)，這(zhe)種充(chong)電(dian)不足(zu)的現象隨著循(xun)環 次數的增(zeng)加而加劇。

1.4. 鋰離子電池(chi)的種類

1.4.1 不可充電的鋰(li)電池有(you)多(duo)種，目前常(chang)用的有(you)鋰(li)-二氧(yang)化錳電池、鋰(li)

—亞硫(liu)酰氯電(dian)(dian)池及鋰和(he)其它化(hua)合物(wu)電(dian)(dian)池。

1)　鋰-二(er)氧化錳電池(Li　MnO2)

鋰(li)-二(er)氧化(hua)錳電(dian)(dian)(dian)池是(shi)一(yi)種(zhong)以(yi)鋰(li)為陽極(ji)、以(yi)二(er)氧化(hua)錳為陰極(ji)，并(bing)采用(yong)有機 電(dian)(dian)(dian)解液的(de)一(yi)次性電(dian)(dian)(dian)池。該電(dian)(dian)(dian)池的(de)主要特(te)點是(shi)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)(ya)高(gao)，額定(ding)電(dian)(dian)(dian)壓(ya)(ya)為 3V(是(shi) 一(yi)般(ban)堿(jian)性電(dian)(dian)(dian)池的(de) 2 倍);終(zhong)止放電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)為 2V;比能(neng)量大(見上(shang)面舉的(de)例子(zi)); 放電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)穩定(ding)可靠;有較好(hao)的(de)儲存性能(neng)(儲存時(shi)間 3 年以(yi)上(shang))、自放電(dian)(dian)(dian)率低(年 自放電(dian)(dian)(dian)率≤2%);工作溫度范(fan)圍(wei)-20℃～+60℃。

該電池可以做(zuo)成不同的(de)外形(xing)(xing)以滿(man)足不同要求(qiu)，它有長(chang)方形(xing)(xing)、圓(yuan)柱形(xing)(xing)及紐 扣形(xing)(xing)(扣式)。

2)可充(chong)電鋰離子(zi)電池

可(ke)充(chong)(chong)電(dian)(dian)鋰離子(zi)電(dian)(dian)池(chi)是目前(qian)手機中(zhong)應用(yong)最廣(guang)泛的電(dian)(dian)池(chi)，但(dan)它較(jiao)為“嬌氣”， 在使用(yong)中(zhong)不可(ke)過充(chong)(chong)、過放(會損(sun)壞電(dian)(dian)池(chi)或(huo)使之(zhi)報廢)。因此，在電(dian)(dian)池(chi)上有(you)保(bao)護(hu)(hu) 元器件或(huo)保(bao)護(hu)(hu)電(dian)(dian)路以(yi)防止昂貴的電(dian)(dian)池(chi)損(sun)壞。 鋰離子(zi)電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)要求(qiu)很高，要 保(bao)證終止電(dian)(dian)壓精度(du)在 1%之(zhi)內(nei)，目前(qian)各大半導體器件廠(chang)已開發出(chu)多種鋰離子(zi) 電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)的 IC，以(yi)保(bao)證安全、可(ke)靠、快速地充(chong)(chong)電(dian)(dian)。

1.4.2 根據鋰離子電(dian)(dian)池(chi)所用電(dian)(dian)解質材(cai)料(liao)不同，鋰離子電(dian)(dian)池(chi)可以分為液

態鋰(li)(li)離(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(lithium ion battery, 簡稱為 LIB)和聚合(he)(he)(he)物(wu)(wu)(wu)(wu)鋰(li)(li)離(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)(p olymer lithium ion battery, 簡稱為 LIP)兩大類(lei)。聚合(he)(he)(he)物(wu)(wu)(wu)(wu)鋰(li)(li)離(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)所 用(yong)(yong)的(de)(de)正負極材料與液(ye)態鋰(li)(li)離(li)(li)(li)子(zi)(zi)都是(shi)相同的(de)(de)，電(dian)(dian)(dian)池(chi)的(de)(de)工(gong)作(zuo)原理也基本一致。 它們的(de)(de)主要(yao)區別(bie)在于電(dian)(dian)(dian)解(jie)質的(de)(de)不同, 液(ye)態鋰(li)(li)離(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)使用(yong)(yong)的(de)(de)是(shi)液(ye)體電(dian)(dian)(dian)解(jie)質, 而聚合(he)(he)(he)物(wu)(wu)(wu)(wu)鋰(li)(li)離(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)則以固體聚合(he)(he)(he)物(wu)(wu)(wu)(wu)電(dian)(dian)(dian)解(jie)質來代(dai)替, 這(zhe)種(zhong)聚合(he)(he)(he)物(wu)(wu)(wu)(wu)可(ke)(ke)以是(shi) “干(gan)態”的(de)(de),也可(ke)(ke)以是(shi)“膠態”的(de)(de),目前大部分(fen)采用(yong)(yong)聚合(he)(he)(he)物(wu)(wu)(wu)(wu)膠體電(dian)(dian)(dian)解(jie)質。聚 合(he)(he)(he)物(wu)(wu)(wu)(wu)鋰(li)(li)離(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)池(chi)可(ke)(ke)分(fen)為三類(lei)：

(1)固(gu)體(ti)聚合(he)物電(dian)(dian)(dian)解質鋰離(li)子(zi)電(dian)(dian)(dian)池(chi)。電(dian)(dian)(dian)解質為聚合(he)物與鹽的混(hun)合(he)物， 這種電(dian)(dian)(dian)池(chi)在常(chang)溫下的離(li)子(zi)電(dian)(dian)(dian)導率低，適于高溫使用(yong)。

(2)凝膠(jiao)聚(ju)合物(wu)(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質鋰(li)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)。即在固(gu)體聚(ju)合物(wu)(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質中加入增 塑(su)劑(ji)等添(tian)加劑(ji)，從而(er)提(ti)高(gao)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)導(dao)率，使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)可(ke)(ke)在常溫下使(shi)用(yong)。 (3)聚(ju)合物(wu)(wu)正(zheng)極(ji)材料(liao)的(de)(de)鋰(li)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)。采(cai)用(yong)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)聚(ju)合物(wu)(wu)作為正(zheng)極(ji)材料(liao)， 其比(bi)(bi)(bi)能量是(shi)現有鋰(li)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de) 3 倍，是(shi)最新一(yi)代(dai)的(de)(de)鋰(li)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)。由于用(yong)固(gu) 體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質代(dai)替了(le)液(ye)(ye)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質,與液(ye)(ye)態(tai)鋰(li)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)相比(bi)(bi)(bi)，聚(ju)合物(wu)(wu)鋰(li)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)具 有可(ke)(ke)薄形化、任(ren)(ren)意(yi)面積化與任(ren)(ren)意(yi)形狀(zhuang)化等優點，也(ye)不會產生(sheng)漏液(ye)(ye)與燃燒爆 炸等安全上的(de)(de)問(wen)題(ti)，因此可(ke)(ke)以用(yong)鋁塑(su)復(fu)合薄膜(mo)制造電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)外殼，從而(er)可(ke)(ke)以提(ti) 高(gao)整個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)比(bi)(bi)(bi)容量;聚(ju)合物(wu)(wu)鋰(li)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)還可(ke)(ke)以采(cai)用(yong)高(gao)分子(zi)(zi)作正(zheng)極(ji)材料(liao)， 其質量比(bi)(bi)(bi)能量將會比(bi)(bi)(bi)目前(qian)的(de)(de)液(ye)(ye)態(tai)鋰(li)離(li)(li)(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)提(ti)高(gao) 50%以上。

此(ci)外,聚合物鋰離子電(dian)(dian)池(chi)在工作(zuo)電(dian)(dian)壓、充(chong)放電(dian)(dian)循(xun)環壽命等方面都比鋰離子電(dian)(dian)池(chi)有所提高。

基于以上優點(dian)，聚(ju)合物鋰離子(zi)電(dian)池(chi)(chi)被譽為下一代鋰離子(zi)電(dian)池(chi)(chi)。 聚(ju)合物鋰離子(zi)(Lithium ion polymer)電(dian)池(chi)(chi)，具有更高(gao)能量密度、小型化(hua)(hua)(hua)、薄型化(hua)(hua)(hua)、 輕量化(hua)(hua)(hua)、高(gao)安(an)全(quan)性、長(chang)循(xun)環壽命與低成本的新型電(dian)池(chi)(chi)。因此(ci)，在未來 2～3 年內(nei)，聚(ju)合物鋰電(dian)池(chi)(chi)取代鋰離子(zi)電(dian)池(chi)(chi)市場(chang)的份額將達 50%。

1.5. 鋰離子電池優缺點

1.5.1 鋰離子(zi)電池具有以下優點：

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

2. 比(bi)能量(liang)大，目前能達到的(de)實(shi)際(ji)比(bi)能量(liang)為 100-125Wh/kg 和 240-300Wh/L(2 倍于(yu) Ni-Cd，1.5 倍于(yu) Ni-MH),未(wei)來(lai)隨著技術發展, 比(bi)能量(liang)可高達 150Wh/kg 和 400 Wh/L

3. 循環壽命長,一般均可(ke)達到 500 次以上(shang),甚至 1000 次以上(shang).對(dui)于小電(dian)(dian) 流放電(dian)(dian)的(de)電(dian)(dian)器(qi),電(dian)(dian)池的(de)使用期限 將倍增電(dian)(dian)器(qi)的(de)競(jing)爭力.

4. 安全性能(neng)好,無(wu)公害,無(wu)記憶效應(ying)(ying).作為(wei)Li-ion前身的(de)鋰(li)電池,因金(jin)屬(shu) 鋰(li)易形成(cheng)枝(zhi)晶發生短路,縮(suo)減了其應(ying)(ying)用領域：Li-ion中(zhong)不(bu)含鎘、鉛、汞等(deng)對 環境有污染的(de)元素：部分(fen)工藝(yi)(如(ru)燒結(jie)式)的(de)Ni-Cd電池存在的(de)一大弊病為(wei) “記憶效應(ying)(ying)”，嚴重(zhong)束縛電池的(de)使用，但Li-ion根本不(bu)存在這方面(mian)的(de)問題。

5. 自放電小，室溫下充(chong)滿電的 Li-ion 儲存 1 個月(yue)后的自放電率為 10%左右，大大低于 Ni-Cd 的 25-30%，Ni、MH 的 30-35%。

6. 可快速充放(fang)電，1C 充電是(shi)容(rong)量可以達(da)到標稱(cheng)容(rong)量的 80%以上。

7. 工作溫度范圍高，工作溫度為-25~45_C，隨著電(dian)解質和正極的 改進(jin)，期(qi)望能擴寬到-40~70_C。

1.5.2.鋰離子電池也(ye)存在著一定的缺點

1. 電池成本較高(gao)。 主要表現在正極材(cai)料 LiCoO2 的(de)價格高(gao) (Co 的(de)資源較少(shao))，電解質(zhi)體系提純困難。

2. 不能大電流放電。 由于有機電解質體系等原因，電池內阻相對

其(qi)他類電(dian)池大。故(gu)要(yao)求較小的放電(dian)電(dian)流密度，一般放電(dian)電(dian)流在 0.5C 以下， 只適(shi)合于中小電(dian)流的電(dian)器使用。

3. 需要保護線路控制 。

A. 過(guo)(guo)充保護：電(dian)(dian)(dian)池過(guo)(guo)充將破(po)壞正極結構(gou)而(er)影響性能和壽(shou)命;同(tong)時過(guo)(guo)充 電(dian)(dian)(dian)使電(dian)(dian)(dian)解液分解，內部壓(ya)力過(guo)(guo)高而(er)導致漏液等問題;故必須(xu)在 4.1V-4.2V 的 恒壓(ya)下充電(dian)(dian)(dian);

B. 過放(fang)保(bao)護：過放(fang)會導致活性物質的恢復困難，故也需要有保(bao)護線(xian)路(lu) 控制(zhi)。

4)充電電池定義

充(chong)電(dian)電(dian)池(chi)(chi)又(you)稱(cheng)：蓄電(dian)池(chi)(chi)、二次(ci)電(dian)池(chi)(chi)，是(shi)可以反復充(chong)電(dian)使用的電(dian)池(chi)(chi)。常見 的有：鉛(qian)酸(suan)電(dian)池(chi)(chi)(用于汽(qi)車時，俗稱(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)(dian)(dian)(dian)池(chi)的(de)額(e)定(ding)容(rong)量(liang)指(zhi)在一定(ding)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)條件(jian)下，電(dian)(dian)(dian)(dian)池(chi)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)至截(jie)止電(dian)(dian)(dian)(dian)壓時(shi)放(fang)(fang)(fang)出(chu)的(de)電(dian)(dian)(dian)(dian) 量(liang)。IEC 標準規(gui)定(ding)鎳鎘和鎳氫電(dian)(dian)(dian)(dian)池(chi)在 20_5℃環境下，以 0.1C 充(chong)電(dian)(dian)(dian)(dian) 16 小時(shi) 后以 0.2C 放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)至 1.0V 時(shi)所(suo)放(fang)(fang)(fang)出(chu)的(de)電(dian)(dian)(dian)(dian)量(liang)為電(dian)(dian)(dian)(dian)池(chi)的(de)額(e)定(ding)容(rong)量(liang)。單位有(you) Ah, mAh (1Ah=1000mAh)

1.6. 如(ru)何正確(que)使用鋰離子電池.

正(zheng)確使用鋰(li)離子電(dian)池應注意以下幾點：

避(bi)免在嚴酷(ku)條件下(xia)使用，如：高溫、高濕度、夏日陽光下(xia)長時(shi)間暴曬等， 避(bi)免將電池投入火中(zhong);

裝、拆電(dian)池時，應確保用(yong)電(dian)器具處于電(dian)源(yuan)關閉狀(zhuang)態;使用(yong)溫度應保持在 -20~55℃之間;

避免將電(dian)池長時(shi)間“存放(fang)”在(zai)停(ting)止使用的(de)用電(dian)器具中;

1.6.1.如何為新(xin)電池充電,

在使(shi)用(yong)鋰(li)電(dian)池中應(ying)注意的(de)是，電(dian)池放置一段時(shi)間(jian)后則進(jin)入休眠狀(zhuang)態，此 時(shi)容(rong)量(liang)(liang)低于(yu)正常值(zhi)，使(shi)用(yong)時(shi)間(jian)亦隨之(zhi)縮短。但鋰(li)電(dian)池很容(rong)易激(ji)活，只要經過 3—5次正常的(de)充放電(dian)循(xun)環就可(ke)激(ji)活電(dian)池，恢復正常容(rong)量(liang)(liang)。由(you)于(yu)鋰(li)電(dian)池本身 的(de)特(te)性，決定了它幾乎沒有(you)記憶(yi)效應(ying)。因此用(yong)戶手機中的(de)新鋰(li)電(dian)池在激(ji)活過

程中，是(shi)不需要特別的(de)(de)方法和設備(bei)的(de)(de)。不僅理論上是(shi)如此，從我自己的(de)(de)實(shi)踐

來(lai)看，從一開始(shi)就采用標準方法充電這種(zhong)“自然激活”方式是最好的(de)。

對于(yu)鋰電(dian)(dian)(dian)池(chi)的(de)(de)“激活”問題，眾多的(de)(de)說法是：充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時間(jian)一定(ding)要超(chao)(chao)過 12 小時，反復做(zuo)三(san)次，以便激活電(dian)(dian)(dian)池(chi)。這種(zhong)“前三(san)次充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)要充(chong)(chong)(chong)(chong) 12 小時以上” 的(de)(de)說法，明(ming)顯是從(cong)鎳電(dian)(dian)(dian)池(chi)(如鎳鎘和鎳氫)延續(xu)下來的(de)(de)說法。所(suo)以這種(zhong)說法， 可以說一開始就是誤傳。鋰電(dian)(dian)(dian)池(chi)和鎳電(dian)(dian)(dian)池(chi)的(de)(de)充(chong)(chong)(chong)(chong)放(fang)電(dian)(dian)(dian)特性有非(fei)常大的(de)(de)區別，而 且可以非(fei)常明(ming)確的(de)(de)告訴(su)大家，在所(suo)查閱過的(de)(de)嚴肅的(de)(de)且正式的(de)(de)技(ji)術(shu)資料中都強 調過充(chong)(chong)(chong)(chong)和過放(fang)電(dian)(dian)(dian)會(hui)對鋰電(dian)(dian)(dian)池(chi)、特別是液體(ti)鋰離(li)子電(dian)(dian)(dian)池(chi)造(zao)成巨大的(de)(de)傷害。因(yin)而 充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)最好按照標(biao)準時間(jian)和標(biao)準方法充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，特別是不要進(jin)行(xing)超(chao)(chao)過 12 個(ge)小時的(de)(de) 超(chao)(chao)長充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)。

此外，鋰(li)電(dian)池(chi)或充電(dian)器(qi)在(zai)電(dian)池(chi)充滿后(hou)都會自動(dong)停充，并不存在(zai)鎳電(dian)充電(dian) 器(qi)所謂的(de)持續 10 幾小(xiao)時(shi)的(de)“涓流(liu)”充電(dian)。也就(jiu)是說(shuo)，如果你的(de)鋰(li)電(dian)池(chi)在(zai)充 滿后(hou)，放(fang)在(zai)充電(dian)器(qi)上也是白(bai)充。而(er)我(wo)們誰都無法保(bao)證電(dian)池(chi)的(de)充放(fang)電(dian)保(bao)護電(dian)路

8 / 18

的(de)特性永不變化和質量的(de)萬無一(yi)失，所以你的(de)電池(chi)將長期處在危(wei)險的(de)邊緣徘 徊。這也是我(wo)們反對長充(chong)電的(de)另一(yi)個理由。

此外(wai)，不可(ke)忽視的另外(wai)一個方面就(jiu)是鋰電池同(tong)樣也(ye)不適合過放電，過放 電對鋰電池同(tong)樣也(ye)很不利。

1.6.2、正常使用中(zhong)應該何(he)時開始充(chong)電(dian)

經常(chang)可以見到這種說(shuo)法，因(yin)為(wei)充放電(dian)的(de)(de)次(ci)數是有限(xian)的(de)(de)，所以應該將手機 電(dian)池的(de)(de)電(dian)盡可能用光再充電(dian)。但是我(wo)找到一(yi)個關于(yu)鋰離(li)子電(dian)池充放電(dian)循環(huan)的(de)(de) 實驗表，關于(yu)循環(huan)壽命的(de)(de)數據(ju)列(lie)出(chu)如下:

循環壽命(ming) (10%DOD):>1000 次

循環壽命 (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)(dian)(dian)(dian)(dian)池(chi)(chi)剩(sheng)余電(dian)(dian)(dian)(dian)(dian)量用(yong)完(wan)再(zai)充的(de)(de)(de)原則并不(bu)(bu)是要你走(zou)向極(ji)端。和(he)長(chang)充電(dian)(dian)(dian)(dian)(dian)一樣流傳 甚廣的(de)(de)(de)一個說(shuo)法，就是“盡量把電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)量用(yong)完(wan)”。這(zhe)種做法其(qi)實只(zhi)是鎳電(dian)(dian)(dian)(dian)(dian) 池(chi)(chi)上的(de)(de)(de)做法，目的(de)(de)(de)是避免記(ji)憶效(xiao)應(ying)發生，不(bu)(bu)幸的(de)(de)(de)是它也在(zai)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)上流傳之今。 曾經有人因為手機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)量過(guo)低的(de)(de)(de)警告出現(xian)后，仍(reng)然不(bu)(bu)充電(dian)(dian)(dian)(dian)(dian)繼續(xu)使(shi)用(yong)一直(zhi)用(yong) 到(dao)自(zi)動關機(ji)(ji)的(de)(de)(de)例(li)子。結果這(zhe)個例(li)子中(zhong)的(de)(de)(de)手機(ji)(ji)在(zai)后來的(de)(de)(de)充電(dian)(dian)(dian)(dian)(dian)及(ji)開機(ji)(ji)中(zhong)均無反(fan) 應(ying)，不(bu)(bu)得不(bu)(bu)送(song)客(ke)服(fu)檢修。這(zhe)其(qi)實就是由于(yu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)因過(guo)度放電(dian)(dian)(dian)(dian)(dian)而(er)導致電(dian)(dian)(dian)(dian)(dian)壓過(guo)低， 以至于(yu)不(bu)(bu)具備正常(chang)的(de)(de)(de)充電(dian)(dian)(dian)(dian)(dian)和(he)開機(ji)(ji)條件造(zao)成的(de)(de)(de)。
