Novel grid for improving short pass of polar plate

Abstract

The invention discloses a novel grid for improving short pass of polar plates, comprising a polar plate (1); a certain corner of the polar plates (1) is a broken corner (2) which is of a broken cornershape, a positive polar plate and a negative polar plate are opposite to the broken corner, namely after grouping by overlaying the polar plates, one of the polar plates of the opposite part is provided with a corner and the other plate is not provided with a corner, and the broken corner (2) of the polar plates (1) adopts an arc lead angle (3). When adopting the novel grid to manufacture batteries, even if the grid transforms, no short pass occurs, thus improving product pass percent and reducing production cost.

Description

technical field [0001] The invention relates to a grid of a battery, in particular to a novel grid for improving the short circuit of a pole plate. Background technique [0002] Chemical power is a device that converts chemical energy into electrical energy. Since Plante (R, G, Plante) successfully trial-produced lead-acid batteries in 1859, and since France Leclanche (G, lechance) made zinc-manganese dry batteries in 1868 , the chemical power supply has experienced more than 100 years of development history, and has now formed an independent and complete technology and industrial system. There are more than 1,000 battery products of different series and models in the world. Chemical power source has become a convenient energy source widely used in people's life. Today, artificial satellites, spaceships, trains, automobiles, submarines, torpedoes, military missiles, rockets, and airplanes are all inseparable from power sources. [0003] The most basic structure of a chemic...

Problems solved by technology

[0006] As we all know, the grid is relatively soft. When assembling the battery, the corners of the plate are very vulnerable to collision, especially in tight assembly batteries, large-capacity batteries, and thin separator batteries. The plate is collided and deformed. Cause a short circuit, and the short circuit battery can only be scrapped, which greatly increases the manufacturing cost

The deformation of the plate can be improved by man-made control, but the battery cannot be produced by making high-quality goods. It needs high production efficiency and continuous production. Therefore, there will always be deformation of the grid. At present, there is no improvement An effective method for plate short circuit
