Li-ion batteries with high capacity using hybrid electrode materials based on carbon nanomaterials with metal sulfides

Storage capacitance and power, as well as the lifetime of electrochemical power sources can be greatly increased using electrodes obtained by combination of different materials. Traditionally used electrode materials for lithium-ion batteries and supercapacitors are carbon materials, e.g., graphite, activated carbon, carbon fibers. New low-dimensional form of carbon such as carbon nanotubes (CNTs) and graphene have great potential for electrochemical applications due to their high specific surface area, electrical conductivity and mechanical strength.

The market of Li- ion batteries is being actively developed, and there are always new technologies of electrode materials. Currently commercial solutions use anode materials with a capacity of about 150 mAh/g; Energo Plus electrode material made of carbon nanotubes with metal sulfides allows achieving capacities more than 750 mAh/g. Activated carbon has a high surface area but low electrical coupling and, hence, little discharge capacity and lower ability of lithium intercalation.
