Abstract: Tetraethyl orthosilicate (TEOS) is used as organic silicon source and blended with mixed salts for ball milling.The carbon element in TEOS calcined at high temperature in molten salt system is recombined into two-dimensional sheet structure while Si-O in TEOS is also reduced in an argon hydrogen atmosphere, and finally 2D SiOx/C anode material is obtained.Electrochemical test results show that the 2D SiOx/C anode material has good electrochemical performance when the calcination temperature is at 900℃.The reversible specific capacity of the material remains at 781.6 mAh·g-1 after 100 cycles at a current density of 0.5 A·g-1.Its excellent electrochemical performance can be attributed to its good structural stability and excellent conductivity.This synthesis method provides a new idea for the preparation of two-dimensional SiOx/C anode materials.
