Abstract
A neptunium ion possesses two isostructural and reversible redox couples (Np
3+
/Np
4+
and NpO2
+
/NpO2
2+
) and is therefore suitable as an
active material for a redox-flow battery. Since the plastic formed carbon (PFC) is known to show the largest k0 values for Np(IV)/Np(III) and
Np(V)/Np(VI) reactions among various carbon electrodes, a cell was constructed by using the PFC, with the circulation induced by bubbling
gas through the electrolyte. In discharge experiments with a neptunium and a vanadium battery using the cell, the former showed a lower
voltage loss which suggests a smaller reaction overvoltage. Because of the high radioactivity of the neptunium, it was difficult to obtain
sufficient circulation required for the redox-flow battery, therefore a model for evaluating the energy efficiency of the redox-flow battery was

developed. By using the known k0 values for neptunium and vanadium electrode reactions at PFC electrodes, the energy efficiency of the
eptunium battery was calculated to be 99.1% at 70 mA cm

, which exceeds that of the vanadium battery by ca. 16%.

. Introduction
Neptunium has two isostructural couples, Np
n+
(n= 3 and
) and NpO2
(n?4)+
(n= 5 and 6), in acidic solutions, where
is the oxidation state of the neptunium. This structural
eature that the neptunium has two isostructural couples
s a unique chemical nature of the light actinide and it
ccompanies the fast electron transfer reactions in each
ouple. In addition, the redox potentials of these neptunium
ouples are as
