一、電芯和電池一樣嗎
電芯和電池(chi)是不一樣的(de)。
對于電(dian)(dian)(dian)(dian)(dian)芯(xin)和電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是兩個不同的(de)(de)(de)概(gai)念,簡(jian)單的(de)(de)(de)來(lai)說的(de)(de)(de)話(hua),電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)就(jiu)像一(yi)個儲存電(dian)(dian)(dian)(dian)(dian)能的(de)(de)(de)容器,而電(dian)(dian)(dian)(dian)(dian)芯(xin)在(zai)這個電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)這個大(da)概(gai)念里(li)面的(de)(de)(de)是個大(da)的(de)(de)(de)模(mo)組(zu),而作為電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)核心部件,單獨拿出來(lai)的(de)(de)(de)說話(hua),電(dian)(dian)(dian)(dian)(dian)芯(xin)就(jiu)相當(dang)于是個半成品,不能直接(jie)當(dang)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)用。
根據電(dian)(dian)芯(xin)的(de)(de)組(zu)成(cheng)來看(kan)(kan),電(dian)(dian)芯(xin)里面含(han)有正、負(fu)極的(de)(de)電(dian)(dian)化(hua)學等部件(jian),不直接使用。只是提供動力的(de)(de),而要(yao)想成(cheng)為成(cheng)品的(de)(de)東西,那么(me)這(zhe)個(ge)東西就(jiu)需要(yao)配上保(bao)護電(dian)(dian)路,然后在(zai)這(zhe)個(ge)的(de)(de)基礎上面,加上外殼等一(yi)系列的(de)(de)組(zu)成(cheng)部件(jian),從而就(jiu)能(neng)夠達到是成(cheng)品電(dian)(dian)池(chi)了。根據電(dian)(dian)芯(xin)的(de)(de)結構來看(kan)(kan)電(dian)(dian)芯(xin)在(zai)電(dian)(dian)池(chi)里面并不等于電(dian)(dian)池(chi)。
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、負極的電化學電芯,不直接使用(yong)。
(2)電池:指盛有電(dian)(dian)解(jie)質溶液(ye)和金(jin)屬(shu)電(dian)(dian)極以產(chan)生電(dian)(dian)流的杯(bei)、槽(cao)或其他容(rong)(rong)器或復合容(rong)(rong)器的部(bu)分空間,能(neng)將化(hua)學能(neng)轉化(hua)成(cheng)電(dian)(dian)能(neng)的裝置。
2、功能不同
(1)電芯:電芯(xin)+保護(hu)電路板(ban)。充電電池去除(chu)保護(hu)電路板(ban)就是(shi)電芯(xin)了。
(2)電池:具有很大的電(dian)極(ji)-電(dian)解(jie)質界(jie)面面積,故可(ke)將電(dian)池等(deng)效為一大電(dian)容(rong)與小電(dian)阻、電(dian)感的串聯回路。
3、特點不同
(1)電芯:粒徑小(xiao),比表面(mian)積(ji)大(da),顏(yan)色(se)白,純度高(gao),電(dian)化學(xue)性能明顯(xian)提高(gao)。可以用到鈦酸鋰(li)電(dian)池材料和(he)鈷(gu)酸鋰(li)電(dian)池材料中。
(2)電池:利用電(dian)(dian)(dian)池(chi)作為能量(liang)來源,可以(yi)得到具有(you)穩(wen)(wen)定電(dian)(dian)(dian)壓,穩(wen)(wen)定電(dian)(dian)(dian)流,長(chang)時(shi)間穩(wen)(wen)定供電(dian)(dian)(dian),受(shou)(shou)外界影響很小的電(dian)(dian)(dian)流,并且電(dian)(dian)(dian)池(chi)結構簡(jian)單,攜帶(dai)方便,充放電(dian)(dian)(dian)操(cao)作簡(jian)便易行,不受(shou)(shou)外界氣候和溫(wen)度(du)的影響
