Abstract

Crystalline Co₃O₄ and Co(OH)₂ were synthesized using Co(NO₃)₂ as a precursor by conventional-hydrothermal and microwave-hydrothermal routes, respectively. The Co₃O₄ phase showed cubic morphologies while the β-Co(OH)₂ phase exhibited plate-like shapes. The electrochemical performances of Co₃O₄ and Co(OH)₂ phases were evaluated as electrode materials for lithium-ion battery anodes, cathodes and supercapacitors. Both Co₃O₄ and Co(OH)₂ phases showed pseudocapacitive performances in Li₂SO₄ and KOH electrolytes. The Co₃O₄ and Co(OH)₂ phases were found to be more promising as anodes than as cathodes in lithium-ion batteries. The Co(OH)₂ electrodes showed higher specific capacitances than those of Co₃O₄ materials.
