Abstract

In this paper, we report a new facile strategy to maximize the charge density for a high-output triboelectric nanogenerator (TENG). It was realized by designing a new cationic material structure consisting of SiO₂ and MoS₂ coated on a Ni-mesh in sequence. Compared with Ni-mesh-based TENGs, this new TENG generated about 13 times higher output power and a superior charge density of over 1000 μC m⁻² with a slow charge decay rate. Its extremely high charge density could be explained by a low work function of MoS₂, an upward bending of the energy band at the interface between MoS₂ and SiO₂, and a high charge capacity of SiO₂. Based on the gear-cam mode, the average output power of the TENG was measured to be about 14.75
