Abstract
The application relates to a metal ion battery, belonging to the technical field of batteries. The metal ion battery comprises a pole piece, wherein the pole piece comprises a base body, and a plurality of mesh structures are arranged on the base body. The mesh structures are arranged in an array. The cross-sectional areas of the plurality of mesh structures are equal. The cross section of the mesh structure is in any one of a rectangle, an equilateral triangle, a square, a circle, a rhombus and an equilateral hexagon. The porosity of the base body is less than or equal to 50%. The above technical scheme has the advantages of high unit energy density, low cost and high space utilization.
