基于前期的研究工作
筛选出最优的硅/碳/石墨(Si@C-G)复合材料作为锂电池的负极材料.本文分析了在不同粘合剂作用下的Si@C-G复合材料
及其对材料电化学性能的影响和粘合剂对硅界面行为产生的变化.结果表明:羧甲基纤维素钠&丁苯橡胶对复合材料的粘合效果最好
其对应的循环性能最好;羧甲基纤维素钠的长直链结构与丁苯橡胶的柔性结构形成的二维网络能够包覆活性材料
使电极片的结构保持稳定
提高了Si@C-G材料在充放电过程中的稳定性.
Through the previous research work
the best Si@C-G composite material was selected as the negative electrode material for lithium batteries.In this paper
the electrochemical properties of Si@C-G composites under different binders and the influence of binders on the interface behavior of silicon are discussed. It is concluded that sodium carboxymethyl cellulose & styrene-butadiene rubber has the best adhesion to the composite material
it corresponds to the best cycle performance. The two-dimensional network formed by the long straight chain structure of sodium carboxymethyl cellulose and the flexible structure of styrene-butadiene rubber can cover the active material
keep the structure of the electrode sheet stable
and further improve the cycle stability of the Si@C-G material.
