title: Synthesis and electrochemical properties of SnWO4.
abstract: In this paper, a pure SnWO4 was synthesized by solvothermal method. The glucose as a carbon sources was mixed with SnWO4 to prepared SnWO4/C composite. The structure and morphology were characterized by XRD and SEM techniques. The electrochemical properties of SnWO4 and SnWO4/C composite were studied by battery comprehensive testing system and AC impedance spectroscopy. The results showed that the alpha-SnWO4 phase was formed and its particles were ranged from 50 to 250 nm. The alpha-SnWO4/C composites behaved higher reversible discharge capacity and better cycle performance than that of alpha-SnWO4. The reversible discharge capacity of SnWO4/C composites was 780 mA h/g at the current density (50 mA/g) and it could keep at 600 mA h/g after 30 cycles. The reason for SnWO4/C composite to behave outstanding electrochemical properties was discussed also.
