摘要

由于各种人类活动都在推动碳中和,开发不依赖化学反应过程或热源的发电方法已变得非常重要。此外,由于材料固有的导电性和电流分流,实现微瓦级输出也是一个挑战。为了应对这一挑战,我们的研究集中于利用非导电介质,将水基低成本微纤维陶瓷棉与氯化钠水溶液结合起来进行发电。电能的主要来源是水分子和表面离子在动态双电层的作用下通过密集的微纤维陶瓷棉的定向运动。这种现象与植物的自然水分蒸腾作用十分相似,从而为环保发电提供了一种新颖而直接的方法。本研究中展示的发电机模块尺寸为 12 × 6 cm2,开路电压为 0.35 V,短路电流为 0.51 mA。这种低成本陶瓷棉适用于无处不在的永久性能源,并有望用作自供电传感器和系统,从而消除对阳光或热量等外部能源的需求。

Harvesting Energy Via Water Movement and Surface Ionics in Microfibrous Ceramic Wools

Due to the push for carbon neutrality in various human activities, the development of methods for producing electricity without relying on chemical reaction processes or heat sources has become highly significant. Also, the challenge lies in achieving microwatt-scale outputs due to the inherent conductivity of the materials and diverting electric currents. To address this challenge, our research has concentrated on utilizing nonconductive mediums for water-based low-cost microfibrous ceramic wools in conjunction with a NaCl aqueous solution for power generation. The main source of electricity originates from the directed movement of water molecules and surface ions through densely packed microfibrous ceramic wools due to the effect of dynamic electric double layer. This occurrence bears resemblance to the natural water transpiration in plants, thereby presenting a fresh and straightforward approach for producing electricity in an ecofriendly manner. The generator module demonstrated in this study, measuring 12 × 6 cm2, exhibited a noteworthy open-circuit voltage of 0.35 V, coupled with a short-circuit current of 0.51 mA. Such low-cost ceramic wools are suitable for ubiquitous, permanent energy sources and hold potential for use as self-powered sensors and systems, eliminating the requirement for external energy sources such as sunlight or heat.

期刊介绍: Energy & Environmental Materials (EEM) is an international journal published by Zhengzhou University in collaboration with John Wiley & Sons, Inc. The journal aims to publish high quality research related to materials for energy harvesting, conversion, storage, and transport, as well as for creating a cleaner environment. EEM welcomes research work of significant general interest that has a high impact on society-relevant technological advances. The scope of the journal is intentionally broad, recognizing the complexity of issues and challenges related to energy and environmental materials. Therefore, interdisciplinary work across basic science and engineering disciplines is particularly encouraged. The areas covered by the journal include, but are not limited to, materials and composites for photovoltaics and photoelectrochemistry, bioprocessing, batteries, fuel cells, supercapacitors, clean air, and devices with multifunctionality. The readership of the journal includes chemical, physical, biological, materials, and environmental scientists and engineers from academia, industry, and policy-making.
