Title: Aniline‐Based Disulfide/Aniline Copolymers as a High Energy‐Storage Material
Abstract: Abstract Aniline‐based disulfide, 5‐amino‐1,4‐dihydrobenzo[d]‐1′,2′‐dithiadiene (DTAn), was synthesized through a new route. The DTAn/aniline copolymers [P(DTAn‐ co ‐An)] were prepared by chemical oxidative polymerization. The results show that the polymerization activity of the DTAn is obviously lower than that of aniline, and the degree of polymerization increases with the increasing feed ratio of aniline and oxidant dosage. The cyclic voltammograms of the copolymers indicate that intramolecular self‐catalyzed effects occurred between the conducting backbone and the S‐S side chain. The charge–discharge tests of Li/P(DTAn‐ co ‐An) cell show an initial specific capacity of 262 mAh · g −1 , which suggests that P(DTAn‐ co ‐An) may be a promising cathode material in secondary lithium batteries. magnified image
