筆記本(ben)電(dian)(dian)(dian)池電(dian)(dian)(dian)芯是什么 筆記本(ben)電(dian)(dian)(dian)池電(dian)(dian)(dian)芯材料(liao)種類介紹

筆記本電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)指(zhi)的(de)(de)(de)(de)是將化學能(neng)、光能(neng)、原子能(neng)等(deng)其它形(xing)式的(de)(de)(de)(de)能(neng)轉(zhuan)化為電(dian)(dian)(dian)能(neng)的(de)(de)(de)(de)裝(zhuang)置，并且轉(zhuan)換的(de)(de)(de)(de)電(dian)(dian)(dian)能(neng)能(neng)夠適用于筆記本電(dian)(dian)(dian)腦。它分為一次(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)（俗稱干電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）和(he)二次(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)（即可反(fan)復(fu)充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)），隨著技術的(de)(de)(de)(de)進步和(he)發展，電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)經歷了鎳鎘電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)到鎳氫電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)（包括金(jin)屬(shu)鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)和(he)鋰(li)聚合(he)物電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）和(he)正(zheng)在(zai)(zai)發展中(zhong)的(de)(de)(de)(de)燃料電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)等(deng)。每一次(ci)技術革新(xin)不但使電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)在(zai)(zai)容量、重量、使用的(de)(de)(de)(de)方便程度的(de)(de)(de)(de)方面有重大的(de)(de)(de)(de)突破(po)，而且也變(bian)得越(yue)(yue)來(lai)越(yue)(yue)環保。

筆記本電池的種類和特性：

鎳鎘電池（Ni-Cd）

它(ta)(ta)是筆(bi)記(ji)本所使用的電(dian)池(chi)中的元老級(ji)人物，但是由于它(ta)(ta)有嚴重的記(ji)憶效(xiao)應以及所使用的陽極材料鎳（Ni）有毒和對環境(jing)會(hui)產生污染，因此很快就被筆(bi)記(ji)本嫌棄了，取而代之(zhi)的是更優秀的鎳氫電(dian)池(chi)。

鎳氫電池（Ni-MH）

它與鎳(nie)鎘電(dian)(dian)(dian)池結構(gou)原理基本(ben)相同，只是將陰極換成(cheng)性能更好、更環保(bao)的(de)無毒的(de)鎳(nie)－金屬氫(qing)化物(wu)材料。雖然(ran)只是小小的(de)改(gai)變(bian)，但卻帶(dai)來了性能上的(de)極大提(ti)高(gao)。它還(huan)有一個優點就(jiu)是記憶(yi)效應不明顯(xian)，這樣就(jiu)使我(wo)們不用再(zai)為那討厭的(de)記憶(yi)效應煩惱從而更加方(fang)便使用。雖然(ran)鎳(nie)氫(qing)電(dian)(dian)(dian)池的(de)性能十分不錯，但隨著(zhu)技術的(de)進步它被(bei)質量更輕、能量密度更高(gao)的(de)鋰電(dian)(dian)(dian)池所替代(dai)，成(cheng)了筆記本(ben)電(dian)(dian)(dian)池歷史(shi)中(zhong)的(de)昨日黃(huang)花(hua)。

鋰電池

很多(duo)人認為(wei)說到(dao)鋰(li)(li)電(dian)池(chi)(chi)(chi)就是(shi)指我們現(xian)在常用的(de)鋰(li)(li)聚合(he)物電(dian)池(chi)(chi)(chi)，其實鋰(li)(li)電(dian)池(chi)(chi)(chi)包括金屬鋰(li)(li)離子電(dian)池(chi)(chi)(chi)（Li－MO2）和(he)鋰(li)(li)聚合(he)物電(dian)池(chi)(chi)(chi)（Li－ion）兩種。因(yin)(yin)為(wei)Li－MO2電(dian)池(chi)(chi)(chi)在1989年進入市場時(shi)發生著火爆炸事件而(er)(er)夭折，因(yin)(yin)而(er)(er)它(ta)很快從人們的(de)視線(xian)中消失，取而(er)(er)代之(zhi)的(de)是(shi)更安全的(de)鋰(li)(li)聚合(he)物電(dian)池(chi)(chi)(chi)。它(ta)重(zhong)量輕，在同(tong)容(rong)量的(de)情況下(xia)它(ta)重(zhong)量只有鎳氫電(dian)池(chi)(chi)(chi)的(de)1/2左右，因(yin)(yin)此(ci)它(ta)迅速成為(wei)移動便攜(xie)設備(bei)的(de)新寵兒(er)，被大多(duo)數筆記本電(dian)腦所(suo)使(shi)用，是(shi)現(xian)在筆記本電(dian)池(chi)(chi)(chi)中的(de)中堅力量。

燃料電池（Fuel Cell）

燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)是筆記(ji)本(ben)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)未來新星(xing)，它有(you)很多(duo)種(zhong)(zhong)類，包括質子交換膜燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)（PEM）、堿(jian)性(xing)燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)（AFC）和(he)(he)固體氧化(hua)物燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)（SOFC）等多(duo)種(zhong)(zhong)，但由(you)于燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)啟動時間和(he)(he)運行(xing)溫度等原(yuan)因(yin)實際上適合(he)筆記(ji)本(ben)電(dian)(dian)(dian)(dian)腦(nao)使(shi)用的(de)(de)(de)燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)只有(you)質子交換膜燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)（PEM）。PEM燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)使(shi)用的(de)(de)(de)燃(ran)(ran)(ran)料(liao)(liao)是甲醇(chun)等，由(you)正(zheng)、負電(dian)(dian)(dian)(dian)極(ji)組成(cheng)它發電(dian)(dian)(dian)(dian)的(de)(de)(de)原(yuan)理是經過(guo)(guo)對甲醇(chun)進行(xing)氫(qing)重整(zheng)后(hou)輸入負極(ji)，氧輸入正(zheng)極(ji)，通(tong)過(guo)(guo)催化(hua)劑的(de)(de)(de)作用，氫(qing)原(yuan)子轉(zhuan)變為質子和(he)(he)電(dian)(dian)(dian)(dian)子，由(you)不(bu)同路徑進入正(zheng)極(ji)，電(dian)(dian)(dian)(dian)子通(tong)過(guo)(guo)內部循環產(chan)(chan)生(sheng)(sheng)電(dian)(dian)(dian)(dian)，質子通(tong)過(guo)(guo)電(dian)(dian)(dian)(dian)解液達到正(zheng)極(ji)，與氧和(he)(he)電(dian)(dian)(dian)(dian)子結合(he)后(hou)產(chan)(chan)生(sheng)(sheng)水和(he)(he)熱。專家們一致認為，制約燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)商(shang)業應用最大的(de)(de)(de)因(yin)素是燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)要(yao)使(shi)用金屬鉑（Pt）即白金做催化(hua)劑使(shi)生(sheng)(sheng)產(chan)(chan)成(cheng)本(ben)一直居高不(bu)下，目前燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)生(sheng)(sheng)產(chan)(chan)成(cheng)本(ben)在500～1000美(mei)(mei)元/千瓦(wa)。研究顯(xian)示，只有(you)當燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)生(sheng)(sheng)產(chan)(chan)成(cheng)本(ben)降(jiang)至50美(mei)(mei)元/千瓦(wa)左右(you)的(de)(de)(de)水平(ping)時才能真正(zheng)為消費者(zhe)所接受(shou)。燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)成(cheng)本(ben)高的(de)(de)(de)主要(yao)原(yuan)因(yin)是尚(shang)未形成(cheng)批量(liang)生(sheng)(sheng)產(chan)(chan)，一旦進入大批量(liang)生(sheng)(sheng)產(chan)(chan)階段，燃(ran)(ran)(ran)料(liao)(liao)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)信息(xi)肯定會大大降(jiang)低。

鋰聚合物電(dian)池的單位能量比目(mu)前的一(yi)般鋰離子電(dian)池提高(gao)了10%，安全性也大大提高(gao)，符(fu)合經濟性和設計原則，因此，市(shi)面上主要銷售的大多(duo)數是鋰聚合物材質筆記本電(dian)池。
