一、電芯和電池一樣嗎
電芯和電池是不一樣的。
對于電(dian)(dian)(dian)(dian)芯和電(dian)(dian)(dian)(dian)池(chi)是兩個不(bu)同(tong)的(de)(de)(de)概念,簡單的(de)(de)(de)來說(shuo)的(de)(de)(de)話(hua),電(dian)(dian)(dian)(dian)池(chi)就像一個儲存電(dian)(dian)(dian)(dian)能(neng)的(de)(de)(de)容器,而(er)電(dian)(dian)(dian)(dian)芯在這(zhe)個電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)這(zhe)個大概念里面的(de)(de)(de)是個大的(de)(de)(de)模組,而(er)作為電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)核心部件,單獨拿出(chu)來的(de)(de)(de)說(shuo)話(hua),電(dian)(dian)(dian)(dian)芯就相當于是個半成(cheng)品,不(bu)能(neng)直接當電(dian)(dian)(dian)(dian)池(chi)用。
根據電(dian)(dian)芯的(de)(de)組成來看,電(dian)(dian)芯里面(mian)含有正、負極的(de)(de)電(dian)(dian)化學等部件,不(bu)直接使用(yong)。只是提供(gong)動力(li)的(de)(de),而要想成為成品的(de)(de)東(dong)西,那么這(zhe)(zhe)個(ge)東(dong)西就(jiu)需要配上(shang)(shang)保(bao)護電(dian)(dian)路,然后在這(zhe)(zhe)個(ge)的(de)(de)基(ji)礎上(shang)(shang)面(mian),加上(shang)(shang)外殼等一系(xi)列的(de)(de)組成部件,從而就(jiu)能夠(gou)達到是成品電(dian)(dian)池了(le)。根據電(dian)(dian)芯的(de)(de)結(jie)構來看電(dian)(dian)芯在電(dian)(dian)池里面(mian)并不(bu)等于(yu)電(dian)(dian)池。
二、電芯和電池的區別是什么
1、指代不同
(1)電芯:指單個含有正、負(fu)極的電(dian)化學電(dian)芯,不直接使(shi)用。
(2)電池:指盛(sheng)有電(dian)(dian)解質溶液和金屬(shu)電(dian)(dian)極(ji)以(yi)產(chan)生電(dian)(dian)流的(de)杯、槽(cao)或(huo)其(qi)他容器或(huo)復合容器的(de)部分空間(jian),能(neng)將化學能(neng)轉化成電(dian)(dian)能(neng)的(de)裝置。
2、功能不同
(1)電芯:電(dian)(dian)芯+保護(hu)電(dian)(dian)路(lu)板。充(chong)電(dian)(dian)電(dian)(dian)池去除保護(hu)電(dian)(dian)路(lu)板就是電(dian)(dian)芯了。
(2)電池:具有很大的電極-電解質界面面積,故可將電池等效為(wei)一大電容與小電阻、電感(gan)的串聯回路(lu)。
3、特點不同
(1)電芯:粒(li)徑小,比表面積大,顏(yan)色白,純度高,電(dian)化學(xue)性能明顯提(ti)高。可以用到鈦酸(suan)鋰電(dian)池材料和鈷酸(suan)鋰電(dian)池材料中。
(2)電池:利用電(dian)(dian)池(chi)作(zuo)為能量來源,可(ke)以得到具有穩定電(dian)(dian)壓,穩定電(dian)(dian)流(liu),長時間穩定供電(dian)(dian),受(shou)外界(jie)影響很小的電(dian)(dian)流(liu),并(bing)且電(dian)(dian)池(chi)結構簡單,攜(xie)帶方便,充放電(dian)(dian)操作(zuo)簡便易行(xing),不(bu)受(shou)外界(jie)氣候和溫度的影響
