With the increasing dependency of human life on wearable electronics, the development of corresponding energy-storage devices is being insensitively pursued. Considering the special usage locations of wearable energy-storage devices, the safety and non-toxicity of electrode materials adopted should be of concern. In this work, a novel all-solid-state wearable supercapacitor based on the renewable-biomolecule emodin, naturally derivable from traditional Chinese herbal rhubarb or Polygonum cuspidatum, was successfully fabricated. Such supercapacitors exhibited excellent charge storage and rate capability with great flexibility and could be integrated into wearable electronics. As a proof of concept, a strap-shaped supercapacitor was fabricated, and it was capable of powering an electronic watch. Our work will promote the development of safe wearable electronics.
随着人类生活对可穿戴电子产品的依赖程度不断提高，相应的储能设备的开发也在紧锣密鼓地进行。考虑到可穿戴储能设备的特殊使用地点，所采用的电极材料的安全性和无毒应该受到关注。在这项工作中，我们成功地制备了一种基于可再生生物分子大黄素的新型全固态可穿戴超级电容器，大黄素可从传统中草药大黄或虎杖中天然获得。这种超级电容器具有优异的电荷存储和倍率性能，同时具有很好的柔韧性，可以集成到可穿戴电子设备中。作为概念验证，我们制备了一个表带形状的超级电容器，它可以为电子表供电。我们的工作将推动安全可穿戴电子产品的发展。
