A supercapacitor made from organic and nature‐based materials, such as conductive polymers (PEDOT:PSS), nanocellulose, and an the organic dye molecule (alizarin), is demonstrated. The dye molecule, which historically was extracted from the roots of the plant rubia tinctorum, is here responsible for the improvement in energy storage capacity, while the conductive polymer provides bulk charge transport within the composite electrode. The forest‐based nanocellulose component provides a mechanically strong and nonporous network onto which the conductive polymer self‐organizes. The electrical and electrochemical properties of the material composition are investigated and prototype redox‐enhanced supercapacitor devices with excellent specific capacitance exceeding 400 F g−1 and an operational stability over >1000 cycles are demonstrated. This new class of supercapacitors, which in part are based on organic materials from plants, represents an important step toward a green and sustainable energy technology.

利用植物中的氧化还原分子提高纸超级电容器的性能
展示了一种超级电容器,该超级电容器由有机和自然材料制成,例如导电聚合物(PEDOT:PSS),纳米纤维素和有机染料分子(茜素)。历史上从植物茜草的根中提取的染料分子在这里负责提高能量存储能力,而导电聚合物在复合电极内提供大量电荷传输。基于森林的纳米纤维素成分可提供机械强度高且无孔的网络,导电聚合物可自组织到该网络上。研究了材料成分的电和电化学特性,并采用了具有超过400 F g -1的优异比电容的氧化还原增强型超级电容器原型设备。并证明了在> 1000个周期内的运行稳定性。这种新型的超级电容器部分基于植物的有机材料,代表了朝着绿色和可持续能源技术迈出的重要一步。
