Description

technical field [0001] The invention relates to an energy storage device, specifically an energy storage device that uses solar power to generate electricity and electrolyze water for energy storage. Background technique [0002] Usually humans use lead-acid batteries or colloidal batteries to store energy for solar photovoltaic power generation. However, since lead-acid batteries and colloidal batteries are chemical batteries, the leakage of acid and alkali will have a certain impact on the environment. At the same time, the above two batteries Due to the frequent chemical reactions in the process of charging and discharging will cause corrosion of the electrodes, the battery life is relatively short, about two to five years. If used improperly, some service lifes only need to be replaced in about one year, and the replaced batteries are difficult to handle due to heavy metals and chemical liquids, which further aggravates the pollution to the human environment. For this r...
