There is plenty of exploitable energy in the ambient environments. Triboelectric nanogenerator is an innovative electricity generation technology to convert the wasted mechanical energy into electrical energy. However, the output of conventional triboelectric nanogenerators cannot be employed efficiently because their tremendous internal resistance limits the current of electrons. Inspired by the principle of lightning rods, for the first time we propose the utilization of electrostatic discharge to improve the performance of triboelectric nanogenerators, which is realized by an opposite needles structure enclosed in an inert atmosphere. When this structure is connected in series with a vertical contact-separation triboelectric nanogenerator, the strong electric field near tips of two needles ionizes the gas around them, forming a conductive plasma channel between the tips, and releasing a mass of free charges. As a result, some exciting performances are obtained in triboelectric nanogenerator. The output peak-to-peak voltage is increased from 300 V to 1300 V, and the equivalent impedance of energy harvesting circuit is reduced from 100 MΩ to 10 kΩ. Especially in the optimal conditions, the maximum continuous power can even be significantly improved by 330.76%. Therefore, this work provides a new strategy for the energy conversion technology, which is significant for the advancement and application of triboelectric nanogenerators.

周围环境中有大量可利用的能量。摩擦电纳米发电机是一种创新的发电技术，可以将浪费的机械能转化为电能。但是，传统的摩擦电纳米发电机的输出不能有效利用，因为它们巨大的内阻限制了电子的电流。受避雷针原理的启发，我们首次提出利用静电放电来改善摩擦电纳米发电机的性能，这是通过在惰性气氛中封闭的相对的针状结构来实现的。当此结构与垂直接触分离式摩擦电纳米发生器串联时，两个针尖附近的强电场将其周围的气体电离，在尖端之间形成导电等离子体通道，并释放大量的自由电荷。结果，在摩擦电纳米发电机中获得了一些令人兴奋的性能。输出峰峰值电压从300 V增加到1300 V，能量收集电路的等效阻抗从100MΩ降低到10kΩ。特别是在最佳条件下，最大连续功率甚至可以显着提高330.76％。因此，这项工作为能量转换技术提供了新的策略，对摩擦电纳米发电机的发展和应用具有重要意义。能量收集电路的等效阻抗从100MΩ降低到10kΩ。特别是在最佳条件下，最大连续功率甚至可以显着提高330.76％。因此，这项工作为能量转换技术提供了新的策略，对摩擦电纳米发电机的发展和应用具有重要意义。能量收集电路的等效阻抗从100MΩ降低到10kΩ。特别是在最佳条件下，最大连续功率甚至可以显着提高330.76％。因此，这项工作为能量转换技术提供了新的策略，对摩擦电纳米发电机的发展和应用具有重要意义。
