The irradiation electrochemical effect refers to a category of effects in which the electrochemical behavior of materials changes under irradiation. Its impacts are mainly reflected in the following aspects: the effect on electrode potential. Irradiation causes the electrode potential of most metals to shift in the positive direction, with the magnitude of this shift being directly related to the accumulation of oxidative decomposition products in the medium; under intense irradiation, the rate at which the potential reaches oxygen saturation increases significantly. Effect on the electrode reaction process: Oxidizing products such as H₂O₂ and O₂ generated by irradiation accelerate the electrochemical reaction rates at both the cathode and anode, thereby increasing the kinetic activity of the reactions. Effect on the corrosion resistance of materials: Irradiation accelerates the corrosion process of non-passivable metals ； For metals with strong passivation properties, as long as the corrosion potential remains in the passivation region, their corrosion resistance generally does not suffer any significant negative impact. Regulating the properties of energy storage materials: By precisely controlling the irradiation parameters, it is possible to introduce controllable defects into the electrode materials, thereby reducing charge transfer resistance and enhancing the specific capacitance and cycle stability of these materials – this represents a new approach for optimizing battery performance.
