A Co(OH)(2)/zeolite nanocomposite with an extraordinarily high specific capacitance is described. Nanometer-sized Co(OH)(2) whiskers on the zeolite surface permit high electrochemical accessibility and a fast diffusion rate of electrolyte through the material, resulting in a specific capacitance approaching the theoretical limit. increasing the Co(OH)(2) loading increases whisker growth (see Figure), until bulk Co(OH)(2) begins to nucleate and grow in solution (arrows).
