Abstract

The invention relates to a grid of a lead-acid battery and a lead-acid battery. The grid comprises a grid-shaped current collector and a frame; the grid-shaped current collector comprises a pluralityof first ribs and tabs, wherein the first ribs extend in a preset direction, and the tabs are connected with the first ribs; the frame comprises a plurality of supporting strips and a border, whereinthe supporting strips are connected together; the first ribs intersect with the supporting strips; the same ends of the first ribs are fastened with the bottom edge of the frame; the first ribs are atleast partially embedded into the supporting strips; the grid-shaped current collector is connected with the frame, so that a mesh structure is formed in the middle of the grid; the density of the frame is smaller than that of the grid-shaped current collector.

Description

technical field [0001] The invention relates to the technical field of energy storage devices, and more specifically, the invention relates to a grid of a lead-acid battery and the lead-acid battery. Background technique [0002] Lead-acid batteries have the advantages of high safety and recyclability. The plates of lead-acid batteries are usually divided into tubular plates and plate plates. Plate-type plates are widely used in lead-acid batteries due to their thinner thickness and lower resistivity. The main disadvantage of the plate plate is that it makes the specific energy of the lead-acid battery lower. [0003] Lead and lead alloys are the main materials of the plates in ordinary lead-acid batteries. Lead is a heavy metal element with a density as high as 11.34g / cm 3 . The invention patent application with the application number CN201210107216.9 discloses a technical scheme of using copper mesh as the main material of the grid current collector of the lead-acid b...
