Problems solved by technology

[0003] When the electrode of the battery reacts, the particles of the reactant are continuously consumed on the surface of the electrode, and the particles of the product are continuously gathered on the surface of the electrode, resulting in a concentration difference between the vicinity of the electrode and the electrolyte solution, causing concentration polarization of the electrode and shortening The half-life of the compound, therefore, the existing battery life is short and the utilization rate of chemical energy is low
