Mnフェライトを活物質として用いたレドックスキャパシタ電極の電気化学特性

抄録

The Mn_xFe_3-xO₄ powders were prepared by a coprecipitation method or a solid state reaction. The effect of specific surface area on electrochemical properties and the relationship between the electrochemical properties and manganese substitution values were examined by BET method and chrono-potentiometry. The results indicate that capacitance per unit weight of MnFe₂O₄ is proportional to specific surface area. Furthermore, capacitance per specific surface of Mn_xFe_3-xO₄ is constant to about 65 μF/cm² despite the increase of the manganese substitution values (x≥1.0).
