This forces the freed electrons to travel to the second electrode through a wire, creating an electric current.
而自由电子则通过一条导线移动至第二电极，从而产生电流。
Each cell consists of a negative electrode and a positive electrode kept apart by a separator soaked in a conductive electrolyte that allows ions, but not electrons, to travel between them.
每个电池元都包括一个正电极和一个负电极，两个电极用一个浸在导电电解液中的隔离器隔开，该电解液允许离子而不是电子在两个电极之间来回传输(译者注：具体参见下面那个电池结构图)。
