Abstract

Herein, we illustrate the electrochemical Na⁺, Mg²⁺ and Al³⁺ ions storage characteristics in organic–inorganic vanadyl acetate [VO(CH₃COO)₂] for electrochemical capacitor. It is found that all these ions can electrochemically react with vanadyl acetate. However, the electrochemical stability is notably pronounced for Na⁺ ion storage in comparison to Mg²⁺ and Al³⁺ ions. Relying on the outcome, a vanadyl acetate based symmetric electrochemical capacitor was evaluated with respect to Na⁺ ion. With incorporation of silica based gel electrolyte, the capacitor demonstrated excellent long-term stability and energy/power density.
