The natural polymers which exist as biomaterial have been applied to auxiliary materials for electric energy storage devices, and the aim of this research was mainly to improve power performance of such devices. First, the characteristics of EDLC with DNA-modified nanocarbon electrodes were examined, and a sharp decrease in ion-diffusion resistance of charge and discharge processes was attained. Moreover, the gel electrolytes which consists of alginic acid and chitosan as biopolymer were applied to EDLC, and the fall of electrode-interface resistance realized improvement in an output power. It was found that these gel electrolytes are applicable also to a lithium-ion battery. Furthermore, we found that these biopolymeric materials can be applied also to the binder of an EDLC electrode as well as a lithium ion battery electrode, and attained the large improvement in each power-device output.

作为生物材料存在的天然聚合物已应用于用于电源储能设备的辅助材料，这项研究的目的主要是为了提高此类设备的功率性能。首先，检查了具有DNA修饰的纳米碳电极的EDLC的特性，并实现了电荷和放电过程的离子 - 扩散抗性的急剧下降。此外，将由藻酸和壳聚糖组成的凝胶电解质应用于EDLC，并且电极接口电阻的降落在输出功率方面已改善。发现这些凝胶电解质也适用于锂离子电池。此外，我们发现这些生物聚合材料也可以应用于EDLC电极的粘合剂以及锂离子电池电极，并在每个功率设备输出中都大大改进。
