Solvothermal synthesis of nanosized CoSb{sub}2 alloy anode for Li-ion batteries

摘要

The nanocrystalline CoSb{sub}2 was prepared by a solvothermal method at various temperatures and was investigated as a potential anode material for lithium-ion batteries. It was found that the CoSb{sub}2 is highly crystallized at 190 ℃ and with almost a single-phase structure. The morphology of the alloy powder plays an important role in their cycling behavior. The large reversible capacity and better capacity retention of these nanosized CoSb{sub}2 alloys make them promising anode materials for Li-ion batteries.
