Electron-Ion Coupling Mechanism to Construct Stable Output Performance Nanogenerator
Study of the effect of the electrode size on the output stability of the SOP-TENG. (a) Normalized voltage generated from the PET-based TENGs with different electrode sizes (i.e., cm2, cm2, and cm2) at 40% RH. The output voltages were normalized according to those of the respective PET-based TENG at 30% RH. (b) Showed the effect of electrode size on the normalized voltage of the SOP-TENG. The electric outputs were measured at 40% RH. The output voltages were normalized according to the voltage outputs of the respective SOP-TENG at 30% RH. (c, d) Systematic comparison of the normalized voltage generated from the PET-based TENGs and SOP-TENGs with different electrode sizes at different RH levels, respectively. (e, f) Showed the induced charge distribution on the surfaces of electrodes in the dry and humid environment, respectively.
