摘要
From facile preparation method and available low-cost raw materials, we have synthesized a novel kind of organodisulfide cathode materials based on anthracene for lithium secondary batteries – anthra[1′,9′,8′-b,c,d,e][4′,10′,5′-b′,c′,d′,e′]bis-[1,6,6a(6a-SIV) trithia]pentalene (ABTH) and its homopolymer (PABTH), investigated the application of the organodisulfides to positive active material for lithium secondary batteries. The organodisulfides were characterized by FT-IR, XPS, and elemental analysis. The cyclic voltammetry tests reveal that the redox reaction of the ABTHs was processed in two steps. The experimental results showed that the polymer has the specific capacity of 300 mAh/g at second cycle and 250 mAh/g at the fifth cycle.
