In the lead-acid storage battery, the grid occupies one fourth of the whole weight, and because the lead price in China is high for a long time, enterprises want to improve the economic benefit of the enterprises, and the enterprises need to start from the grid structure. At present, grids are developing towards miniaturization and light weight, and meanwhile, brand new high specific energy requirements are put forward by the market for lead-acid storage batteries. In recent years, lead-acid battery manufacturers reduce the weight of grids by means of a mesh-drawing grid, a punching grid, a conductive plastic grid and the like, and lead consumption is reduced. However, the conductive plastic grid cannot be produced in batch, and the expanded grid and the punched grid are already applied to various lead-acid storage battery manufacturers, so that the weight of the grid needs to be further reduced when the grid is expected to stand out in market competition which tends to be white and hot.

In order to reduce the lead consumption of the grid, most lead-acid storage battery manufacturers adopt the method of reducing the thickness of the whole grid, but in order to ensure the production smear feasibility and the battery service life, the thickness of the grid cannot be reduced without bottom lines, the grid is too soft and cannot be smeared due to too low thickness, and the rib of a lug part of the battery is too thin and broken in the using process.

In addition, the vast majority of grid corrosion occurs in the grid headspace as found by extensive post-market battery anatomy. The reason is that the utilization rate of active substances at the bottom of the battery is low, the corrosion speed of the grid is low, the utilization rate of the active substances close to the lug is high, the charging and discharging current is large, and the corrosion speed of the grid is relatively high.
