Abstract:

A highly stable sodium ion battery anode was prepared by deposition of hydroperoxostannate on graphene oxide from hydrogen-peroxide-rich solution followed by sulfidization and 300 [degree]C heat treatment. The material was characterized by electron microscopy{,} powder X-ray diffraction and X-ray photoelectron spectroscopy which showed that the active material is mostly rhombohedral SnS2 whose (001) planes were preferentially oriented in parallel to the graphene oxide sheets. The material exhibited >610 mA h g-1 charge capacity at 50 mA g-1 (with >99.6% charging efficiency) between 0 and 2 V vs. Na/Na+ electrode{,} high cycling stability for over 150 cycles and very good rate performance{,} >320 mA h g-1 at 2000 mA g-1.
