Lead-acid accumulator grid suitable for high-efficiency discharge

Abstract

The invention discloses a lead-acid accumulator grid suitable for high-efficiency discharge. The lead-acid accumulator grid comprises a lug (1), a frame (2) and grids (5), wherein the grids (5) are formed by crossly connecting vertical ribs (3) with transverse ribs (4), the grids (5) are arranged in the frame (2), and the lug (1) is welded outside the frame (2), so that a grid is formed integrally; the lug (1), the transverse ribs (4), the vertical ribs (3) and the frame (2) have the same thickness; and the length direction of the grids is consistent with the height direction of the grid. The lead-acid accumulator grid solves the problems of air hole, the cracking of the ribs, burrs, cracks and the like in the conventional grid, greatly prolongs the service life of batteries, and greatly improves the stability of quality and the discharge performance of large current of the batteries.

Description

technical field [0001] The invention relates to an accessory of a maintenance-free lead-acid battery, in particular to a lead-acid battery grid suitable for high-efficiency discharge. Background technique [0002] For lead-acid batteries, the grid used to produce the plates is very important. The role of the grid in the battery is to support the active material, act as a carrier for the active material, conduct and collect current, and distribute the current evenly on the active material. The traditional grid has the following production and performance problems: (1) There are many pores on the grid. When there are pores, the pores of the grid are easy to corrode, have high resistance, and are easy to break during use. (2) Ribs If the ribs are too thin, the contact area between the ribs and the lead paste is small during the coating process, and the paste is easy to drop, and the conductivity is also poor. (3) The ribs are broken, the lead paste is not full or falls when co...

Problems solved by technology

The traditional grid has the following production and performance problems: (1) There are many pores on the grid. When there are pores, the pores of the grid are easy to corrode, have high resistance, and are easy to break during use. (2) Ribs If the ribs are too thin, the contact area between the ribs and the lead paste is small during the coating process, and the paste is easy to drop, and the conductivity is also poor. (3) The ribs are broken, the lead paste is not full or falls when coating the board, and the current cannot flow during charging and discharging. Through, (4) burrs, when wrapping the board, the burrs are easy to pierce the partition and cause a short circuit, (5) Casting is difficult to form, lead-calcium and lead-antimony alloys can solve the problem of difficult forming to a certain extent, but it makes the board The grid is easily corroded, and the hydrogen evolution potential is reduced, resulting in a shortened battery life
