The invention discloses a lead-acid storage battery grid with a confluence lug and a super-pore cut and stretched net being welded together. The grid has the technical characteristics that lead and a lead alloy are rolled into a lead belt according to a required thickness; a super-pore lead net is made with a precision net cutting and stretching process; and the confluence lug made of the lead and the lead alloy is welded integrally with the super-pore lead net through a patch welding process in order to obtain the lead-acid storage battery grid. Through adoption of the grid, the pore size of a lead-acid storage battery grid in the prior art is reduced greatly. Meanwhile, the sizes of grid ribs are reduced, the surface area of the grid is increased greatly, and the active substance utilization ratio of a battery is increased greatly, so that the specific energy, charging/discharging performance and service life of a lead-acid storage battery are improved greatly.
