A facile and low-cost method is proposed to design CoCl2 center dot 6H(2)O/CoOOH, an excellent electrode material for pseudocapacitors. The microstructures were investigated by X-ray techniques and transmission electron microscopy. It is shown that the obtained sheet-like CoOOH film can fix the inner Co2+ ions and realize a higher utilization of the active material. The high porous materials CoOOH/Co(OH)(2) are favorable to charge transfer and ion diffusion, leading to a superior capacitance of 3562 F g(-1) at 1 A g(-1).
