水溶液钠离子电池价格低廉、安全性高且环境友好，是一种极具前景的大规模储能体系。然而，受制于水溶液的电化学窗口以及无机刚性晶格对于体积较大的钠离子的限制作用，可供选择的电极材料有限且可逆容量偏低。因此，探寻和发展新型正负极材料是发展水溶液钠离子电池的一个重要方向。本研究拟利用聚合物柔性骨架对于阳离子的尺寸限制较小，资源丰富且结构多样，设计合成不同结构的自掺杂聚合物阴极和共轭羰基聚合物阳极，构建全有机水溶液钠离子电池。具体研究内容包括：在p-掺杂的导电聚合物主链上接枝烷基钠盐，n-掺杂的导电聚合物主链上接枝共轭羰基，分别构建富钠的聚合物正极体系和贫钠的聚合物负极体系；通过研究聚合物电极在水溶液钠离子电池中的电化学行为，探索不同聚合物结构、电解液组分对电化学性质的影响；进一步研究聚合物在水溶液中储钠的电化学反应机理，为发展清洁、廉价的全有机水溶液钠离子电池提供理论基础知识和技术支持。

Aqueous sodium ion batteries are considered as promising electric energy storage technology for large scale stationary because of their advantages of low cost, safety and better environmental compatibility. However, Na-host materials for the aqueous sodium ion batteries are extremely limited because of the narrow electrochemical window of aqueous electrolytes and the strict restrictions of the metal oxide lattices on the larger Na+. Therefore, it is important to search and develop new generations of Na-host materials for aqueous batteries. Flexible polymer materials seem to be promising candidates because of their resource abundance, structural diversity and less restrictions on the cation size. In this study, we intend to design and synthesis self-doped polymers and carbonyl polymers as the cathode and anode materials to construct all organic aqueous sodium ion batteries. Following are the specific contents：Na-rich cathodes are developed by grafting the p-doped conducting polymers with ionizable sodium alkyl, while Na-defect anodes are developed by grafting the n-doped conducting polymers with carbonyl groups; The effect of the polymer structures and aqueous electrolytes on the electrochemical properties of the electrodes will be investigated by studying the electrochemical performances of the polymer electrodes；The reaction mechanism of the polymer electrodes will be revealed to provide theoretical guidance for the regular design and applications of new generations of all-organic aqueous Na-ion batteries with low cost and environmental friendliness.
