Energy & Environmental Materials 2024年第2期7卷 347-353页

作者： Xianpeng fu Yuhan Qin Zhi Zhang Guoxu Liu Jie cao Beibei Fan Zhaozheng Wang Zheng Wang Chi Zhang CAS Center for Excellence in Nanoscience Beijing Key Laboratory of Micronano Energy and Sensor Beijing Institute of Nanoenergy and Nanosystems Chinese Academy of Sciences School of Nanoscience and Technology University of Chinese Academy of Sciences Center on Nanoenergy Research School of Physical Science and Technology Guangxi University

As an emerging technology to convert environmental high-entropy energy into electrical energy, triboelectric nanogenerator(TENG) has great demands for further enhancing the service lifetime and output performance in practical applications. Here, an ultra-robust and high-performance rotational triboelectric nanogenerator(R-TENG) by bearing charge pumping is proposed. The R-TENG composes of a pumping TENG(P-TENG), an output TENG(O-TENG), a voltage-multiplying circuit(VMC), and a buffer *** P-TENG is designed with freestanding mode based on a rolling ball bearing, which can also act as the rotating mechanical energy harvester. The output low charge from the P-TENG is accumulated and pumped to the noncontact O-TENG, which can simultaneously realize ultralow mechanical wear and high output performance. The matched instantaneous power of R-TENG is increased by 32 times under 300 r/min. furthermore, the transferring charge of R-TENG can remain 95% during 15 days(6.4 × 10～6cycles)continuous operation. This work presents a realizable method to further enhance the durability of TENG, which would facilitate the practical applications of high-performance TENG in harvesting distributed ambient micro mechanical energy.
