Embodiments of the present application disclose a battery repair method and apparatus, and relate to the battery field, so as to improve a battery repair effect. The method includes: determining, by a power system, a failure mode of a battery according to an abuse record of the battery or a performance parameter of the battery, where the abuse record includes a usage record of a situation in which a preset usage range of the performance parameter of the battery is exceeded, and the performance parameter of the battery is used to represent performance of the battery; determining, by the power system according to the failure mode of the battery, a power repair policy for repairing the battery; and repairing, by the power system, the battery according to a selected power repair policy. According to the method, a failing battery can be repaired.

Battery repair method and apparatus

An artificial electromagnetic material is provided. The artificial electromagnetic material includes at least one material sheet. Each material sheet includes a laminary substrate and a plurality of artificial microstructures attached to the substrate. The substrate is made from transparent material. Because the substrate is made from transparent material, therefore the artificial electromagnetic material is capable of generating responses to visible light wave and convergence, divergence, deflection of visible light wave and so on can be achieved.
