一、電芯和電池一樣嗎
電芯和電池是不一樣的。
對于(yu)電(dian)(dian)(dian)(dian)(dian)芯和電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)兩個(ge)(ge)(ge)(ge)不同的(de)(de)(de)(de)概念,簡單(dan)的(de)(de)(de)(de)來(lai)說的(de)(de)(de)(de)話(hua),電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)就像一個(ge)(ge)(ge)(ge)儲存電(dian)(dian)(dian)(dian)(dian)能的(de)(de)(de)(de)容器,而(er)電(dian)(dian)(dian)(dian)(dian)芯在這個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)這個(ge)(ge)(ge)(ge)大概念里面的(de)(de)(de)(de)是(shi)個(ge)(ge)(ge)(ge)大的(de)(de)(de)(de)模組,而(er)作為電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)核心部件,單(dan)獨(du)拿出來(lai)的(de)(de)(de)(de)說話(hua),電(dian)(dian)(dian)(dian)(dian)芯就相當(dang)于(yu)是(shi)個(ge)(ge)(ge)(ge)半成品(pin),不能直接當(dang)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)用。
根據電(dian)芯的組(zu)成(cheng)(cheng)(cheng)來(lai)看,電(dian)芯里(li)(li)面(mian)含有正、負(fu)極的電(dian)化學等(deng)部件,不(bu)直接使用。只是(shi)提(ti)供動力(li)的,而要想成(cheng)(cheng)(cheng)為成(cheng)(cheng)(cheng)品的東西,那么這個(ge)東西就需要配上保(bao)護(hu)電(dian)路(lu),然(ran)后在(zai)這個(ge)的基礎上面(mian),加上外(wai)殼等(deng)一系(xi)列的組(zu)成(cheng)(cheng)(cheng)部件,從(cong)而就能夠(gou)達到是(shi)成(cheng)(cheng)(cheng)品電(dian)池(chi)了(le)。根據電(dian)芯的結(jie)構來(lai)看電(dian)芯在(zai)電(dian)池(chi)里(li)(li)面(mian)并不(bu)等(deng)于電(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(hua)學電芯,不直接使(shi)用。
(2)電池:指盛有(you)電解質溶(rong)液和(he)金屬電極以產生電流的杯、槽(cao)或其(qi)他容(rong)器(qi)(qi)或復合容(rong)器(qi)(qi)的部分(fen)空間,能(neng)將(jiang)化(hua)學(xue)能(neng)轉化(hua)成電能(neng)的裝(zhuang)置。
2、功能不同
(1)電芯:電(dian)(dian)芯+保護(hu)電(dian)(dian)路板。充電(dian)(dian)電(dian)(dian)池去除保護(hu)電(dian)(dian)路板就是(shi)電(dian)(dian)芯了(le)。
(2)電池:具有很大的電極-電解質界(jie)面面積,故可將電池(chi)等效(xiao)為一(yi)大電容與小電阻、電感的串(chuan)聯回路。
3、特點不同
(1)電芯:粒(li)徑小,比表(biao)面積大,顏色白,純(chun)度(du)高(gao),電(dian)化學性能明顯提高(gao)。可(ke)以用到(dao)鈦酸鋰電(dian)池材(cai)料(liao)和鈷酸鋰電(dian)池材(cai)料(liao)中。
(2)電池:利用電池(chi)作為能量來源,可以得到具有穩定電壓,穩定電流(liu),長時間(jian)穩定供電,受外界影(ying)響很小的電流(liu),并且電池(chi)結構簡單,攜帶方(fang)便,充放電操作簡便易行(xing),不受外界氣(qi)候和溫度的影(ying)響
