Abstrakt: Self-stacked Co(3)O(4) nanosheets separated by carbon layers were synthesized via a facile method. They exhibit excellent electrochemical performance that results from superior electronic conductivity endowed by carbon, a reduced Li(+) diffusion length within the building blocks and a large electrode/electrolyte contact area due to the interspaces between the blocks.
