SnO2/g-C3N4 nanocomposite as high capacity anodes for next generation Lithium-ion batteries

Abstract

Recently, incorporation of two dimensional layered hetero structures with anode material have received huge attention in energy storage application. Here, SnO2/g-C3N4 nanocomposite is synthesized by hydrothermal method. The electrochemical behavior of SnO2/g-C3N4 nanocomposite anode is studied. The structural analyzes validate the formation of tetragonal rutile structure. Microscopy images indicates needle like morphology. SnO2/g-C3N4 delivers initial discharge capacity of 1100 mAh g−1 and 218 mAh g−1 on 200 cycles at 0.1C-rate. The enhanced reversible capacity can be ascribed to the presence g-C3N4, improves the structural stability of the material during cycling.
