一、背夾電池容量是多少
背(bei)夾電池現在(zai)大容量的也不會超過8000毫安。
有些商家(jia)(jia)標20000m，這(zhe)個(ge)數字(zi)(zi)和容量(liang)沒(mei)有關系，只是很(hen)多(duo)買(mai)家(jia)(jia)喜歡(huan)搜20000毫(hao)安(an)的(de)背夾，所以商家(jia)(jia)在標題(ti)上寫了個(ge)20000m讓你搜到他的(de)商品，當然也有虛標20000毫(hao)安(an)的(de)，很(hen)多(duo)買(mai)家(jia)(jia)都被這(zhe)數字(zi)(zi)誤導了。
有些店家的背夾是(shi)根本(ben)不寫(xie)容(rong)量(liang)的，只在(zai)顏色分類里寫(xie)大容(rong)量(liang)款(kuan)和小容(rong)量(liang)款(kuan)，具體容(rong)量(liang)不告訴(su)你(ni)，因為(wei)寫(xie)真(zhen)實(shi)容(rong)量(liang)的話，只有幾千毫(hao)安，比(bi)其他(ta)店家的容(rong)量(liang)低(di)，買家會(hui)覺得(de)容(rong)量(liang)會(hui)太小了，如果不寫(xie)真(zhen)實(shi)容(rong)量(liang)虛標(biao)，標(biao)10000毫(hao)安或(huo)者20000毫(hao)安，如果沒有小二撐腰，又(you)怕被人(ren)投訴(su)。
二、背夾式電池的工作原理是什么
背夾式電(dian)(dian)池(chi)的工(gong)作原(yuan)(yuan)(yuan)理是(shi)利用原(yuan)(yuan)(yuan)電(dian)(dian)池(chi)反(fan)(fan)應屬于放熱的反(fan)(fan)應，一般是(shi)氧(yang)(yang)(yang)化還(huan)原(yuan)(yuan)(yuan)反(fan)(fan)應，但區別(bie)于一般的氧(yang)(yang)(yang)化還(huan)原(yuan)(yuan)(yuan)反(fan)(fan)應的是(shi)，電(dian)(dian)子(zi)(zi)(zi)轉(zhuan)移不(bu)是(shi)通(tong)過(guo)氧(yang)(yang)(yang)化劑和還(huan)原(yuan)(yuan)(yuan)劑之間(jian)的有效碰撞完成(cheng)的，而是(shi)還(huan)原(yuan)(yuan)(yuan)劑在(zai)負(fu)極(ji)上失電(dian)(dian)子(zi)(zi)(zi)發(fa)生(sheng)(sheng)氧(yang)(yang)(yang)化反(fan)(fan)應，電(dian)(dian)子(zi)(zi)(zi)通(tong)過(guo)外電(dian)(dian)路輸送到正(zheng)極(ji)上，氧(yang)(yang)(yang)化劑在(zai)正(zheng)極(ji)上得電(dian)(dian)子(zi)(zi)(zi)發(fa)生(sheng)(sheng)還(huan)原(yuan)(yuan)(yuan)反(fan)(fan)應，從而完成(cheng)還(huan)原(yuan)(yuan)(yuan)劑和氧(yang)(yang)(yang)化劑之間(jian)電(dian)(dian)子(zi)(zi)(zi)的轉(zhuan)移。兩(liang)極(ji)之間(jian)溶液中離子(zi)(zi)(zi)的定向移動和外部導線中電(dian)(dian)子(zi)(zi)(zi)的定向移動構成(cheng)了閉合回路，使(shi)兩(liang)個電(dian)(dian)極(ji)反(fan)(fan)應不(bu)斷(duan)進行，發(fa)生(sheng)(sheng)有序的電(dian)(dian)子(zi)(zi)(zi)轉(zhuan)移過(guo)程，產(chan)生(sheng)(sheng)電(dian)(dian)流，實現化學(xue)能向電(dian)(dian)能的轉(zhuan)化。
