Our group has researched energetic ionic liquid propellants (EILPs) based on ammonium dinitramide (ADN) as the main constituent of the propellants. Electrolysis ignition is attracting attention as a new ignition method for the low ignitability, which is a characteristic of ADN-based EILPs. On the other hand, it is expected that the water contained in a solution due to the hygroscopicity of ADN is involved in the electrolysis of ADN-based EILPs and affects the ignition delay time and the reaction pathway. Therefore, it is essential to understand the effect of water on the electrochemical characteristics of ADN. The aim of this study is to understand the effect of water on the electrochemical characteristics of ADN by using cyclic voltammetry (CV), ultraviolet visible (UV) spectroscopy and electric analysis. CV confirmed whether ADN aqueous solution electrolyzes by comparing with the perchloric acid aqueous solution. From the cyclic voltammogram of these aqueous solutions, it was seemed that ADN does not electrolyze in the water. supported that it was clarified that the electrolysis peak of ADN was not observed in the aqueous solution system, and the decomposition reaction of ADN proceeded after the electrolysis of water occurred.
