All-organic batteries are a promising sustainable energy storage technology owing to the wide availability, flexibility, and recyclability of organic/polymeric compounds. The development of all-organic or polymer batteries is still a challenge, as both electrode materials need to be carefully optimized to have a wide difference of redox potential and compatibility with the electrolyte. Herein, dual redox-active polyimides based on phenothiazine and naphthalene tetracarboxylic dianhydride units are presented. After only one optimization step, the electrodes based on these dual redox polymers can be applied simultaneously as anode and cathode in a symmetric all-organic battery. The phenothiazine functional polyimide shows two redox active voltages at around 2.5 and 3.7 V (vs. Li/Li+ ) with high discharge capacities of 160 mAh g-1 . Moreover, the symmetric full battery delivers high power density up to 1542 W kg-1 with stable cyclability for 1000 cycles. This work demonstrates an efficient strategy to develop dual redox active polymer electrodes for next generation all-polymer batteries.

包含双氧化还原活性聚合物作为阴极和阳极材料的对称全有机电池。

由于有机/高分子化合物的广泛可用性,灵活性和可回收性,全有机电池是一种有前途的可持续能源存储技术。全有机或聚合物电池的开发仍然是一个挑战,因为两种电极材料都需要仔细优化,以使氧化还原电势和与电解质的相容性差异很大。在此,提出了基于吩噻嗪和萘四羧酸二酐单元的双重氧化还原活性聚酰亚胺。仅需一个优化步骤,即可将基于这些双重氧化还原聚合物的电极同时用作对称全有机电池中的阳极和阴极。吩噻嗪官能聚酰亚胺在约2.5和3.7 V(vs. Li / Li +)处显示两个氧化还原活性电压,放电容量高达160 mAh g-1。而且,对称全电池可提供高达1542 W kg-1的高功率密度,并具有1000次循环的稳定循环能力。这项工作展示了开发用于下一代全聚合物电池的双重氧化还原活性聚合物电极的有效策略。
