We had prepared the capacitor electrodes using porous-MnO₂ particles, however the capacitor electrodes showed low performance due to the MnO₂ particles are in several micro sizes. In this paper, we have fabricated honeycomb structured films with MnO₂ nanoparticles for capacitor electrodes. In addition, to improve the low conductivity of MnO₂ itself, honeycomb films were coated by polypyrrole. Polypyrrole coated honeycomb film can solve the low conductivity and also can be expected to obtain the high performance capacitors.
