摘要

Uniform hollow carbon-coated polydymite (Ni3S4) microspheres were synthesized in a solution via an in situ carbon-coating and Ostwald ripening-based route. The thin carbon coating layer and the hollow core enhanced the electrochemical performance of Ni3S4 as a Li-ion battery anode. At a current density of 0.1C (about 100 mA g(-1) ), they exhibited an extremely high reversible capacity of about 1003 mA h g(-1). These polydymite-based composites also displayed a long stable cycling performance and a high capacity retention, with a reversible capacity of 480 mA h g(-1) at 1C rate and a capacity retention of about 83% after 500 cycles.
