电(dian)(dian)(dian)极(ji)(ji)电(dian)(dian)(dian)势的(de)产(chan)生(sheng)，与建立(li)的(de)双电(dian)(dian)(dian)层(ceng)有关，不同(tong)系列的(de)电(dian)(dian)(dian)池(chi)(chi)的(de)标称电(dian)(dian)(dian)压为：铅酸蓄(xu)(xu)电(dian)(dian)(dian)池(chi)(chi)2.0V；碱(jian)性(xing)蓄(xu)(xu)电(dian)(dian)(dian)池(chi)(chi)1.5V，锌银蓄(xu)(xu)电(dian)(dian)(dian)池(chi)(chi)1.5V，镍氢、镍镉电(dian)(dian)(dian)池(chi)(chi)为1.2V。锂离子电(dian)(dian)(dian)池(chi)(chi)3.6V。电(dian)(dian)(dian)动(dong)势是(shi)电(dian)(dian)(dian)池(chi)(chi)在(zai)开路时，正极(ji)(ji)平衡(heng)电(dian)(dian)(dian)极(ji)(ji)电(dian)(dian)(dian)势与负极(ji)(ji)平衡(heng)电(dian)(dian)(dian)极(ji)(ji)电(dian)(dian)(dian)势之(zhi)差，由电(dian)(dian)(dian)池(chi)(chi)中进行的(de)反应所(suo)决定(ding)，与电(dian)(dian)(dian)池(chi)(chi)形状、尺寸无关，电(dian)(dian)(dian)动(dong)势愈高的(de)电(dian)(dian)(dian)池(chi)(chi)，理论(lun)上能输出的(de)能量(liang)就(jiu)愈大。
