Direct current triboelectric nanogenerators (DC-TENGs), based on triboelectrification and corona discharge, exhibit advantages of high output energy and low crest factor. However, the air breakdown that occurs at the interface of tribo-layers due to charge accumulation from triboelectrification results in energy loss. Efficiently capturing triboelectric charges is a great challenge for the improvement of the output energy of DC-TENGs. Herein, we propose a new strategy to efficiently capture triboelectric charges within the interface by rationally arranging charge-collecting electrodes (CCEs), achieving a remarkable 396% enhancement in output charge compared with the conventional electrostatic induction method. The rolling mode constant current TENG, using the reasonable arrangement of CCEs, produces an ultrahigh constant current of 0.51 mA with an ultra-low crest factor of 1.02. This constant current TENG achieves an output charge density of 10.06 mC m−2, surpassing all other types of TENGs reported. Additionally, it obtains an average power density of 9.8 W m−2, a remarkable 49-fold compared with the conventional DC-TENG. This work offers insight into the working mechanism of charge collection through corona discharge and proposes an effective charge-collecting strategy in the triboelectrification process.

高效率摩擦电荷捕获，实现高输出直流电
基于摩擦起电和电晕放电的直流摩擦纳米发电机（DC-TENG）具有高输出能量和低波峰因数的优点。然而，由于摩擦起电的电荷积累而在摩擦层界面处发生空气击穿，导致能量损失。有效捕获摩擦电荷是提高DC-TENG输出能量的巨大挑战。在此，我们提出了一种新策略，通过合理布置电荷收集电极（CCE）来有效捕获界面内的摩擦电荷，与传统静电感应方法相比，输出电荷显着提高了396％。滚动模式恒流TENG利用CCE的合理布置，产生0.51mA的超高恒流和1.02的超低波峰因数。这种恒流TENG实现了10.06 mC m -2的输出电荷密度，超过了报道的所有其他类型的TENG。此外，它的平均功率密度为9.8 W m -2，是传统DC-TENG的49倍。这项工作深入了解了通过电晕放电收集电荷的工作机制，并提出了摩擦起电过程中有效的电荷收集策略。
