Abstract

Manganese oxide electrodes possessing pseudo-capacitance behaviors were successfully made with a simple sol-gel method. The experimental results showed that the specific capacitance was 101.2 F/g for pure manganese oxide films after annealing at 300° C. However, the specific capacitance increased to 232.3 F/g with iron acetate (1.0 mol% Fe) addition and after annealing at 350° C. The surface morphology observations revealed that the annealing temperature of 350° C produced a higher surface area film with smaller pores. X-ray diffraction results showed that the manganese-iron oxide was composed of Mn ₃O₄ and Mn₂O₃ phases, without iron oxide diffraction peaks. The manganese-iron oxide electrode with Mn ₃O₄ and Mn₂O₃ phases exhibited good electrochemical performance and capacitance efficiency.
