Abstract: Currently, the performance improvement of triboelectric nanogenerators (TENGs) mainly depends on materials, structures, and energy management circuits. In this article, we propose a power bonding diagram model that is similar to the vertical contact-separation TENG. This model can handle systems with multiple forms of energy in a unified way, and intuitively reveal the interaction and energy conversion relationships among the components of the TENG system during operation. Various factors that affect the TENG output performance can be quantitatively described using parameters in the power bonding diagram model of the TENG. Through parameter simulation analysis, it can be found that different changes in parameters during a contact-separation motion of the TENG will have different impacts on its output performance. Among them, the contact charge amount q9 determines the theoretical maximum output electric energy Emax of the TENG. In practical applications, increasing the value of the nonlinear energy R6 during the contact process of the TENG as much as possible will make the actual output electric energy of the TENG approach Emax. The parameter analysis of the power bonding diagram model of the TENG can inspire researchers to improve the output electric energy from both theoretical and practical aspects.
