The rapid growth of flexible and wearable electronics makes it an urgent requirement to develop mobile and sustainable energy sources for these devices. Triboelectric nanogenerator (TENG) stands out for its outstanding performance. However, high output performance and energy conversion efficiency TENG still remains one of the most crucial barriers for practical applications. In this paper, we systematically analyze the relationship of maximum instantaneous output power and energy conversion efficiency with the material parameters, structural parameters and experimental parameters. Firstly, we obtain the explicit equations for the transferred charge, output voltage, output current and maximum instantaneous power from the contactmode model and governing equation. Then it is deeply studied how the material parameters, structure parameters and experimental condition can influence the output performance. Finally, the relationship of energy conversion efficiency with the TENG parameters is investigated to provide guidance for rational design of TENG. The high efficiency energy source could greatly promote the development of flexible electronics.
