Electron-Ion Coupling Mechanism to Construct Stable Output Performance Nanogenerator

Recently, triboelectric nanogenerators (TENGs) have been promoted as an effective technique for ambient energy harvesting, given their large power density and high energy conversion efficiency. However, traditional TENGs based on the combination of triboelectrification effect and electrostatic induc...
