The common current collector is generally aluminum foil, copper foil, composite aluminum foil, composite copper foil, carbon-coated current collector and the like. The role of the current collector in the battery is known as a current collecting structure. The current of the battery is transferred and collected through the current collectors of the positive and negative electrodes. Defects can occur in the production process of different current collectors, for example, a traditional aluminum foil is a sheet metal material formed by a plurality of rolling processes by a rolling machine, and in the rolling process, due to unreasonable equipment or process, some protruding points or foreign particles are often generated; for the composite copper foil, in the magnetron sputtering process, due to high temperature, metal particles can lead to the formation of granular copper sputtering particles; in the production process of the carbon-coated aluminum foil, some particles are generated on the surface due to uneven particle size distribution of the slurry. This current collector often has the disadvantage of protruding points during the production process.
