Abstract
Herein, we report the preparation and characterization of the ZnWO<inf>4</inf> and ZnWO<inf>4</inf>/SiO<inf>2</inf> nanocomposite. The ZnWO<inf>4</inf>/SiO<inf>2</inf> nanocomposite exhibits 570 mAh g?1 discharge capacity and 314 mAh g?1 charge capacity at 10 mA g?1 for the primary cycle. The increasing amount of SiO<inf>2</inf> in the ZnWO<inf>4</inf>/SiO<inf>2</inf> nanocomposite increases the overall performance of the composite. The synergetic effect between the ZnWO<inf>4</inf> and SiO<inf>2</inf> enhances the rate capability, specific capacity, cycle stability and coloumbic efficiency of the composite. The good electrochemical performance of ZnWO<inf>4</inf>/SiO<inf>2</inf> nanocomposite makes it a promising anode for Lithium ion battery. © 2020 Elsevier B.V.
