摘要
探究不同硫源对锂离子电池负极材料电化学性能影响.通过硫代硫酸钠硫源法和硫脲硫源法制备实验材料,并选择将不同原材料物质的量比的四种锂离子电池负极材料作为样品,通过实验测试样品的电化学性能.当物质的量比为1∶2 时,通过使用酒石酸锑钾和硫代硫酸钠作为原料制备的锂离子电池负极材料具有较好的电化学性能,其放电化学容量可以达到600 mA·h/g以上,远高于石墨负极材料的容量.实验结果表明,不同硫源对锂离子电池负极材料样品的形貌结构和电化学性能产生了显著影响.
Abstract
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.
