Electrolytic Co, Ni-Bimetalsulfide Composites with Hydrophilizated Multi-Wall Carbon Nanotubes in a Prototype Lithium Accumulator

摘要

Electrolytic Co, Ni-bimetalsulfide composites with hydrophilizated multiwall carbon nanotubes (Co, Ni-S, C) appear to be more promising electrode materials in the redox reaction with lithium than the composites of the transition metal suhldes with graphites. The discharge capacity of Co, Ni-S, C-composites in the prototype lithium accumulator (550-725 mA h/g) exceeds the theoretic discharge capacity of graphite (372 mA h/g) used in commercial hthium-ion batteries.
