Analysis of the Influence of Different Sulfur Sources on the Electrochemical Performance of Lithium-ion Battery Negative Electrode Materials
Explore the influence of different sulfur sources on the electrochemical performance of lithium-ion battery negative electrode materials.Experimental materials were prepared using sodium thiosulfate sulfur source method and thiourea sulfur source method,and four types of lithium-ion battery negative electrode materials with different mass ratios of raw materials were selected as samples.The electrochemical performance of the samples was tested through experiments.When the ratio of substances is 1:2,the lithium-ion battery negative electrode material prepared by using potassium antimony tartrate and sodium thiosulfate as raw materials has good electrochemical performance,and its discharge chemical capacity can reach 600 mA·h/g or more,far higher than the capacity of graphite negative electrode material.The experimental results indicate that different sulfur sources have a significant impact on the morphology,structure,and electrochemical performance of lithium-ion battery negative electrode material samples.
