The light actinide has two kinds of the isostructural redox couple, An
4+
/An
3+
and AnO
2
2+
/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 Np
4+
/Np
3+
and NpO
2
2+
/NpO
2
+
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+
/U
3+
and UO
2
2+
/UO
2
+
couples is expected to be feasible in the aprotic solvents.
