摘　　要：研究了一种新型锂电池正极材料邻氨基二苄基二硫化物(OABD)及其聚合物(POABD)的电化学性能.该材料在低倍率(0.1C)下,单体OABD的首次放电比容量达到96 mAh·g-1;聚合物POABD的首次放电比容量达到290 mAh·g-1,在2.0 V处有明显的放电平台,循环6次后容量保持在100 mAh·g-1,材料聚合后电池性能改善明显.This paper presents a novel lithium battery cathode material aniline-based polyorganodisulfide and its electrochemical performance of polymer. At 0. 1 C rate, the monomer OABD initial discharge specific capacity reached 96 mAh · g- 1 - 1 ; the polymer POABD initial discharge specific capacity of up to 290 mAh·g , had a clear discharge of platforms at the 2.0 V, after 6 cycles capacity was maintained at 100 mAh·g-1. The results indicated that the battery performance of the material improved significantly after the polymerization.
