Electrolytic Cо, Ni-bimetalsulfid сomposites with hydrofillizated multiwall carbon nanotubes (Со, Ni-S, С) seem to be more promising electrode materials in the redox reaction with lithium than the composites of the transition metal sulfides with graphites. Discharge capacity of Со, Ni-S, С-composites in a model lithium accumulator (550–725 mА×h/g) exceeds the theoretical graphite discharge capacity of (372 mА×h/g) used commercially in lithium-ion batteries.
Keywords: Cо, Ni-bimetalsulfid, modification, multi-wall carbon nanotubes, lithium accumulator.
