Sulfur, Nitrogen Dual Doped Reduced Graphene Oxide Supported Two-Dimensional Sb2S3 Nanostructures for the Anode Material of Sodium-Ion Battery

摘要

Developing alternative of Li-based energy storage system are inevitable and demanding because of depleting Li source and increasing cost. In this aspect Na-based electrochemical energy storage devices such as Na-ion batteries has drawn significant attention due to ubiquity, low cost and less toxic nature. Development of electrode material with novel architecture and high specific capacity is important and challenging too. Herein, we have demonstrated a novel two-dimensional nanostruc- tured hybrid anode material based on Sb2S3 and, sulfur and nitrogen dual doped reduced graphene oxide for Na-ion battery. Hybrid material was synthesized by solvothermal process. X-ray diffraction pattern, Raman and FTIR spectral, and microscopic measurements exhibits successful synthesis of crystalline and two-dimensional layered structure material. The hybrid material shows excellent properties towards Na+ storage properties.
