可充电有机电池的实际实现因其低电子电导率而受到阻碍，这限制了电极复合材料中的有机活性材料含量并导致低净电极能量密度。此外，活性材料溶解到电解质中会导致循环寿命缩短。在这项研究中，含有少量糖醇的导电聚合物混合物聚（3,4-乙烯二氧噻吩）/聚苯乙烯磺酸盐被用作可充电有机电池中的粘合剂和隔膜。因此，活性材料含量增加至80wt%，循环寿命延长。
The practical realization of rechargeable organic batteries is stalled by their low electron conductivity, which limits the organic-active material content in the electrode composite and results in a low net electrode energy density. Additionally, the dissolution of active materials into the electrolyte causes a short cycle life. In this study, a conductive polymer mixture, poly(3,4-ethylenedioxythiophene)/polystyrenesulfonate, containing a small amount of sugar alcohol was used as the binder and separator in a rechargeable organic battery. Consequently, the active material content was increased up to 80 wt%, and the cycle life was extended.
