Abstract

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.
