有机二硫化物及其聚合物是在 80年代末才发展起来的一种新型的储能材料 ,这种材料的分子结构中含有双硫键 (— S—S— ) ,基于其可逆的电解聚 -电聚合过程 ( 2 S-S— S+2 e-)而发生能量交换 ,其理论能量密度高达 150 0～ 350 0 Wh/ kg,实际能量密度可达 830 Wh/ kg。而且这种材料有一个很大的优点是可以按预定的方式控制其有机基团和分子结构以及通过共聚、共混来改变其物理、化学和电化学性能。本文将介绍这种物质的反应机理、有关动力学参数的测定、电化学行为、导电聚合物对这种材料的电催化作用等方面的研究情况。
Organic disulfides and their polymers are a new type of energy storage materials developed in the late 1980s. The molecular structure of this material contains disulfide bonds (-S-S-), based on its reversible electrolytic poly (2 SS-S + 2 e-), the theoretical energy density reaches 150 0 ~ 350 0 Wh / kg and the actual energy density reaches 830 Wh / kg. Moreover, there is a great advantage of this material in that it can control its organic groups and molecular structure in a predetermined manner and change its physical, chemical and electrochemical properties through copolymerization and blending. This article will describe the reaction mechanism of this material, the determination of kinetic parameters, electrochemical behavior, the conductive polymer on the electrocatalytic effect of such materials research.
