Preparation and Characterization of Silicon-based Negative Electrode Materials for Lithium-ion Batteries
A high-performance silicon-based negative electrode material for lithium-ion batteries was prepared by reacting Si powder,SiO2 powder,and propylene as the main raw materials under high temperature conditions to obtain a silicon-based core.The silicon-based core was coated with sodium carbonate sodium hydroxide,silicon tripolyphosphate,and silica sol.The particle size,XRD,SEM,and other characteristics of the silicon-based negative electrode material sample were characterized,and the results showed that it has good conductivity.A button type battery was prepared using silicon-based negative electrode material and subjected to charge and discharge tests.The results showed that the battery performance prepared with this material was excellent.
