Design of Pore and Matter Architectures in Cobalt Oxide Electrode for Supercapacitor

수퍼커패시터용 산화코발트전극의 세공과 재료구조의 설계

We describe the preparation of a cobalt oxide in which the solid-pore architecture of the material is controllably varied. All $CoO_2$ gels derived from $CoCl_2$-based sol-gel synthesis, but exhibit markedly different final pore structures based on how the pore fluid is removed from forces that result from extraction are either low or nonexistent. These nanoscale mesoporous materials have higher $CoO_2$ crystallites. Controlling both the pore and solid architecture on the nanoscale offers a strategy for the design of new supercapacitor and charge-storage materials.
