N2 - The light actinide has two kinds of the isostructural redox couple, An 4+/An3+ and AnO22+/AnO 2+. The battery with these couples is expected to be excellent energy efficiency due to the rapid electrode reactions. In the present paper, the standard rates for Np4+/Np3+ and NpO 22+/NpO2+ electrode reactions were evaluated by the cyclic voltammetry and the energy efficiency in the neptunium battery was estimated from the standard rate constants. As a result, the efficiency is found to be excellent. Moreover, the uranium battery with U 4+/U3+ and UO22+/UO2 + couples is expected to be feasible in the aprotic solvents.
