摘    要:有机电极材料因其理论比容量高、低成本、环境友好以及分子结构可设计性强等特点,有望成为下一代可持续和多功能能量储存设备的有效电极材料。然而,根据“相似相溶”原理,该类材料极易溶解在有机电解液中,导致电池容量衰减快、循环稳定性和倍率性能也较差。目前已有许多研究致力于通过“固定化”过程解决有机电极材料的溶解问题。本综述针对有机电极材料的固定化策略展开评述,介绍了有机电极材料的固定化机理,以及各种固定化策略在不同种类有机电极材料中所起的作用,指出了有机电极材料面临的挑战,并对未来的研究和改进方向进行展望。

关 键 词:有机电极材料  溶解  固定化  二次电池

Abstract:Organic electrode materials are expected to be the effective electrode materials for next generation of sustainable and versatile energy storage devices because of their high theoretical specific capacity,low cost,environmental friendliness and molecular design ability.However,according to the principle of similar compatibility,the organic electrode materials dissolve easily in organic electrolytes,leading to rapid decay of reversible capacity,poor cycle stability and rate performance.Many researches have been devoted to restraining the dissolution of organic electrode materials by immobilization.This review focuses on the strategies of immobilization for organic electrode materials.The immobilization mechanism and the role of various strategies for different kinds of organic electrode materials are introduced,the challenges faced by organic electrode materials are then outlined,and finally the future research trend and improvement directions have been envisaged.
Keywords:organic electrode material  dissolution  immobilization  secondary battery
