In 2020, a droplet-based electricity generator (DEG) was proposed. Compared with the traditional water drop generator structure, the voltage and current generated by the DEG structure are much higher. In our work, an aluminum electrode with a superhydrophobic surface was prepared by electrodepositing an aluminum substrate in an organic electrolyte. This electrode is applied to the DEG friction generator to optimize the coupling process between the surface water droplets and the DEG structure, which reduces the residual water droplets while maintaining the same level of electrical output characteristics. And the model of the solid-liquid coupling is also discussed.
