Embodiment approach 1

[0014] This embodiment provides a method for detecting the timeliness of a battery grid, including the following steps:

[0015] A. Randomly select 10 large grids, and randomly cut out a small grid from the 10 large grids respectively, to obtain 10 small grids;

[0016] B. Measure the pre-detection length of one of the diagonals of the 10 small grids respectively, and obtain a total of 10 pre-detection lengths (in mm);

[0018] C. If figure 1 , hang 10 small grids respectively, and keep the diagonal line measured above vertically, and then hang a weight of 100g at the bottom of the diagonal line;

[0019] D. After hanging for 60s, remove the small grid, and measure the post-detection lengths of the above-mentioned diagonals of the 10 small grids again, and obtain a total of 10 post-test lengths (in mm);

Embodiment approach 2

[0023] This embodiment provides a method for detecting the timeliness of a battery grid, including the following steps:

[0024] Steps A-D are exactly the same as those in Embodiment 1, and will not be repeated here.

[0025] E. Calculated by the above 10 pre-test lengths and 10 post-test lengths, the average value of the extreme difference is 0.49mm, which is less than the reference value of 0.5mm, indicating that the deformation of the grid is small, and the aging strength of the grid meets the process requirements .

Embodiment approach 3

[0027] This embodiment provides a method for detecting the timeliness of a battery grid, including the following steps:

[0028] Steps A-D are exactly the same as those in Embodiment 1, and will not be repeated here.

[0029] E. Calculated by the above 10 pre-test lengths and 10 post-test lengths, the average value of the extreme difference is 0.45mm, which is less than the reference value of 0.5mm, indicating that the deformation of the grid is small, and the aging strength of the grid meets the process requirements .

Abstract

The invention relates to the field of storage batteries, and discloses a method for detecting the timeliness of storage battery grids, comprising the following steps: randomly extracting N large grids, and randomly cutting out a small grid from the N large grids; Measure the pre-detection length of a diagonal line of the N small grids respectively; hang the N small grids respectively, keep the diagonal line vertically, and hang a preset weight at the bottom of the diagonal line weights; after hanging for a preset time, remove the small grid, and measure the post-detection lengths of the diagonals of the N small grids respectively again to obtain N post-detection lengths; if the N pre-detection lengths are passed If the average of the extreme difference values ​​calculated from the N lengths after detection is less than the reference value, then the aging strength of the grid meets the process requirements; otherwise, it fails to meet the process requirements. Compared with the prior art, the detection method is simple and accurate, and the aging hardening meets the process requirements, which is conducive to smearing, avoids quality problems such as deformation and cards, and improves the qualified rate of plate cutting.

Description

technical field [0001] The invention relates to the field of storage batteries, in particular to a method for detecting the timeliness of storage battery grids. Background technique [0002] The grid is a key component of the lead-acid battery, and its role is mainly manifested in two aspects: one is as a "skeleton" to support the positive and negative active materials, and the other is as a conductor of current, which serves as an output and input for each part of the plate. The effect of current. As a skeleton, the grid must have good mechanical properties; as a current conductor, the grid must have good bonding ability with the active material. The lead-acid battery grid material is mainly lead, and appropriate amount of other metal elements are added according to different purposes, and it is formed by casting, pulling, punching, continuous casting and other methods. Different molding methods lead to differences in the mechanical properties of the grid and the ability ...
