The invention discloses a lead-acid battery grid. The grid adopts a foamed lead-based board; the surface of the board and the profile in any direction of the board form irregular convex-concave faces (distributed with small honeycomb pores in the board). Compared with a casting alloy grid in the same size, the weight of the grid is reduced by 20 to 50 percent; the area of the foamed lead-based grid is 5 to 15 times of that of the casting alloy grid so as to increase the contact area of the foamed lead-based grid and active substances, reduce internal resistance and improve the utilization rate of the active substances; and the foamed lead-based grid has large negative board capacity, the capacity increases 10 to 30 percent and the specific energy increases 15 to 35 percent. The foamed lead-based grid has good mechanical performance and controllable alloy compositions, and can use pure lead, lead calcium alloy, tin-lead alloy, lead-calcium tin-aluminium alloy and rare earth alloy.
Description
Technical field: [0001] The invention relates to a lead-acid battery, in particular to a pole plate grid of the lead-acid battery. Background technique: [0002] The grid is an important part of the valve-regulated lead-acid battery, which is used to coat the active material and realize the charging and discharging function of the battery. The current grids are all made by casting, the cross-section of the ribs is triangular or trapezoidal, the junctions are at right angles, and the longitudinal and transverse ribs are evenly distributed. The contact area between the grid and the active material is small, and the utilization rate of the active material is low. Invention content: [0003] The technical problem to be solved by the present invention is to provide a lead-acid storage battery grid, which has a large contact area with the active material and a high utilization rate of the active material. [0004] The present invention is realized through the following technic...
