Abstract

Triboelectric nanogenerators (TENG) have been widely used in various fields as an efficient energy harvesting device. Rotary TENG can harvest energy in the form of water energy, wind energy, and so on. However, almost all of the rotary TENGs reported so far are solid-solid contacts. The solid-solid TENG is prone to friction loss during operation, which results in the service life and stability not being adequately guaranteed. In this paper, a rotary solid-liquid TENG (RSL-TENG) is proposed to solve the above problems. The results show that RSL-TENG has high stability after up to 50 hours of continuous 600000 cycles of operation with no decay of the transferred charge after 50 hours. The charge density of RSL-TENG is as high as 52.5 μC/m² when using fluorinated ethylene propylene (FEP) film and 80 ml of purified water. Compared with the reported solid-liquid TENG (SL-TENG), the charge density obtained in this paper is relatively high. The output voltage, short-circuit current, and transferred charge of the RSL-TENG are 246.6 V, 3.9 μA, and 283.4 nC, respectively. After testing with ions commonly found in wastewater, RSL-TENG is found to have output performance with different characteristics. The output voltage, short-circuit current, and transferred charge of the copper ionic solution with the best output performance are 195.8 V, 3.3 μA, and 265.2 nC, respectively. The experimental results show that the liquid type has a certain influence on the output performance of RSL-TENG, which can be used to distinguish the type of ionic solution.

期刊介绍： Nano Energy is a multidisciplinary, rapid-publication forum of original peer-reviewed contributions on the science and engineering of nanomaterials and nanodevices used in all forms of energy harvesting, conversion, storage, utilization and policy. Through its mixture of articles, reviews, communications, research news, and information on key developments, Nano Energy provides a comprehensive coverage of this exciting and dynamic field which joins nanoscience and nanotechnology with energy science. The journal is relevant to all those who are interested in nanomaterials solutions to the energy problem. Nano Energy publishes original experimental and theoretical research on all aspects of energy-related research which utilizes nanomaterials and nanotechnology. Manuscripts of four types are considered: review articles which inform readers of the latest research and advances in energy science; rapid communications which feature exciting research breakthroughs in the field; full-length articles which report comprehensive research developments; and news and opinions which comment on topical issues or express views on the developments in related fields.
