一、電芯和電池一樣嗎
電芯和電(dian)池(chi)是不一(yi)樣的。
對于電(dian)(dian)芯和電(dian)(dian)池(chi)是(shi)(shi)兩個不同的(de)(de)概念(nian),簡單的(de)(de)來(lai)說的(de)(de)話(hua),電(dian)(dian)池(chi)就(jiu)像一個儲存電(dian)(dian)能的(de)(de)容器,而(er)電(dian)(dian)芯在這(zhe)個電(dian)(dian)池(chi)的(de)(de)這(zhe)個大概念(nian)里面的(de)(de)是(shi)(shi)個大的(de)(de)模組,而(er)作(zuo)為電(dian)(dian)池(chi)的(de)(de)核心(xin)部件,單獨拿(na)出來(lai)的(de)(de)說話(hua),電(dian)(dian)芯就(jiu)相當(dang)于是(shi)(shi)個半成品,不能直(zhi)接當(dang)電(dian)(dian)池(chi)用。
根(gen)據電(dian)(dian)(dian)(dian)(dian)芯的(de)組成(cheng)來看(kan),電(dian)(dian)(dian)(dian)(dian)芯里(li)面含有正、負極(ji)的(de)電(dian)(dian)(dian)(dian)(dian)化學等(deng)(deng)部(bu)件,不直接使用。只是(shi)提供(gong)動力的(de),而(er)(er)要(yao)想成(cheng)為成(cheng)品(pin)的(de)東(dong)(dong)西(xi),那么這(zhe)個東(dong)(dong)西(xi)就需(xu)要(yao)配上保護(hu)電(dian)(dian)(dian)(dian)(dian)路,然后在這(zhe)個的(de)基礎上面,加(jia)上外殼等(deng)(deng)一系列的(de)組成(cheng)部(bu)件,從而(er)(er)就能夠達到是(shi)成(cheng)品(pin)電(dian)(dian)(dian)(dian)(dian)池(chi)了。根(gen)據電(dian)(dian)(dian)(dian)(dian)芯的(de)結構來看(kan)電(dian)(dian)(dian)(dian)(dian)芯在電(dian)(dian)(dian)(dian)(dian)池(chi)里(li)面并不等(deng)(deng)于電(dian)(dian)(dian)(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(zhi)單個含有正(zheng)、負極(ji)的電(dian)化學電(dian)芯,不直接(jie)使用。
(2)電池:指盛有電(dian)解質溶液和金屬電(dian)極(ji)以產生電(dian)流的(de)杯、槽或(huo)其(qi)他容器或(huo)復合容器的(de)部分空間(jian),能(neng)(neng)將(jiang)化學能(neng)(neng)轉化成電(dian)能(neng)(neng)的(de)裝置。
2、功能不同
(1)電芯:電(dian)芯+保護(hu)電(dian)路板。充電(dian)電(dian)池去(qu)除保護(hu)電(dian)路板就是電(dian)芯了。
(2)電池:具有很大的電(dian)極-電(dian)解質界面面積,故可將(jiang)電(dian)池等效(xiao)為(wei)一大電(dian)容與(yu)小電(dian)阻、電(dian)感的串聯回路。
3、特點不同
(1)電芯:粒徑小,比表面積大,顏色(se)白(bai),純度高(gao),電化學(xue)性能明顯提高(gao)。可以用到(dao)鈦酸鋰(li)電池(chi)材料(liao)和鈷酸鋰(li)電池(chi)材料(liao)中。
(2)電池:利用電(dian)池(chi)作為能量來源,可(ke)以得到具有穩(wen)(wen)定電(dian)壓,穩(wen)(wen)定電(dian)流,長時間穩(wen)(wen)定供電(dian),受(shou)外界(jie)(jie)影響(xiang)很小的電(dian)流,并且電(dian)池(chi)結(jie)構簡單,攜帶(dai)方便(bian),充放電(dian)操作簡便(bian)易(yi)行,不受(shou)外界(jie)(jie)氣候和(he)溫度的影響(xiang)
