Accumulator grid

Abstract

The invention relates to an accumulator grid, which comprises a lug, a frame, transverse bars and longitudinal bars, wherein the longitudinal bars are distributed along the middle part of the frame from the lug side towards the two sides in a way of radioactive rays. In the accumulator grid provided by the invention, based on the principle that the length of the bevel edge is less than that of the sum of two right-angle sides, the longitudinal bars on encryption board grid which are not vertical to the bottom side are intensified to shorten the conduction path of an electric current. The accumulator grid provided by the invention effectively shortens the conduction path of the electric current, which means the defect of long current conduction path in the prior art is overcome. Thus, the accumulator grid effectively reduces the internal drop of an accumulator and prolongs the service life of the accumulator.

Description

technical field [0001] The invention relates to battery grids and belongs to the technical field of electric power storage. Background technique [0002] Currently used as a battery grid, the grid with vertical vertical ribs is generally used. The battery plate made of this structure grid has a long current conduction path, which causes a large internal pressure drop of the battery, resulting in The reduction of output power; when used as a starting battery, the large discharge capacity at the moment of high-power output will cause de-current, so that the current and potential distribution on the grid will be uneven, and the lead paste on the plate will change unevenly and fall off. , not only reduces the holding capacity of the lead paste, but also causes the connection between the positive and negative electrodes, resulting in an increase in self-discharge, which reduces the capacity and the service life of the battery. Contents of the invention [0003] The purpose of ...
