Abstract

An attractive organic electrode material, poly (2-chloro-3,5,6-trisulfide-1,4-benzoquinone) (PCTB), as an active material for rechargeable lithium batteries was investigated. It was prepared by polymerization of chloranil through thioether bonds. Because the existence of {CCl} in the product, {PCTB} exhibits a superior lithium-storage performance with high potential. A positive-electrode that incorporated {PCTB} showed a discharge capacity of 138.65 mAh/g at 30 mA/g with an average voltage of 2.72 V.
