Chemical electromotive force

…This work is the electromotive force mentioned above, and the source of work is the chemical energy stored in the battery. In this sense, the electromotive force in a battery is called chemical electromotive force. The potential difference between the positive and negative electrodes is equal to the work that a unit charge receives from the battery, that is, the electromotive force (when current is flowing in the circuit, the potential difference between the two electrodes is smaller than the electromotive force due to the internal resistance of the battery). …

*Some of the terminology explanations that mention "chemical electromotive force" are listed below.

…この仕事が上述の起電力で，仕事源は電池に蓄えられた化学的エネルギーである。この意味で電池における起電力は化学起電力と呼ばれる。正極と負極の電位差は，単位電荷が電池から受ける仕事すなわち起電力に等しい(回路に電流が流れているときには，電池の内部抵抗のため両極間の電位差は起電力より小さくなる)。…
