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 mu C 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 W m(-2).
