干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)（Dry cell）是(shi)一種(zhong)以糊狀電(dian)(dian)(dian)(dian)解(jie)液來產(chan)生(sheng)直(zhi)流電(dian)(dian)(dian)(dian)的(de)化學電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)（濕電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)則為使用液態電(dian)(dian)(dian)(dian)解(jie)液的(de)化學電(dian)(dian)(dian)(dian) 池(chi)(chi)(chi)），屬于一次電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，是(shi)日(ri)常生(sheng)活之中為普遍(bian)使用，以及輕便(bian)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。它可在實驗室內自制(zhi)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)們(men)可以使用于很多電(dian)(dian)(dian)(dian)器(qi)用品上。

普通(tong)干電(dian)(dian)池(chi)大(da)都(dou)是(shi)錳(meng)鋅電(dian)(dian)池(chi)，中間是(shi)正極碳(tan)棒，外(wai)包石墨和(he)二氧化(hua)錳(meng)的(de)混合物，再外(wai)是(shi)一層纖(xian)維網(wang)。網(wang)上(shang)涂有(you)很厚的(de)電(dian)(dian)解質糊，其構成是(shi)氯化(hua)氨溶液(ye)和(he)淀(dian)粉(fen)，另(ling)有(you)少量防(fang)腐劑。

干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)屬于化學(xue)(xue)電(dian)(dian)(dian)(dian)(dian)源中的原(yuan)電(dian)(dian)(dian)(dian)(dian)池(chi)，是(shi)一種(zhong)一次性電(dian)(dian)(dian)(dian)(dian)池(chi)，它以二(er)氧化錳為(wei)正極，以鋅(xin)筒為(wei)負極，把化學(xue)(xue)能轉(zhuan)變為(wei)電(dian)(dian)(dian)(dian)(dian)能供給外(wai)電(dian)(dian)(dian)(dian)(dian)路。在化學(xue)(xue)反應(ying)中由(you)于鋅(xin)比錳活潑，鋅(xin)失去(qu)電(dian)(dian)(dian)(dian)(dian)子被氧化，錳得到電(dian)(dian)(dian)(dian)(dian)子被還(huan)原(yuan)。
