Problems solved by technology

[0006] However, this kind of aluminum-based lead composite material, because aluminum is an extremely active metal, the pole plate made of aluminum-based lead composite material is immersed in acid for a long time during the application process, and aluminum is extremely not resistant to corrosion. If there is a slight gap on the lead layer, the acid will easily penetrate into the composite electrode, corrode the aluminum, and destroy the original design of the electrochemical performance of the composite electrode. Therefore, the application of aluminum-based lead composite materials as lead-acid battery plates exists. The hidden danger of unstable electrochemical performance

Abstract

The invention relates to a production process of a plate grid. Carbon, aluminum or conducting alloy is adopted for manufacturing the plate grid, lead or lead alloy with the thickness of 0.1-2mm is sprayed on the surface layer of the plate grid after the plate grid is formed, the lead layer on the surface and the plate grid are bonded through strong extrusion, or a thin lead plate with the thickness of 0.1-0.8mm is strongly extruded to be clad on the surface layer of the plate grid, so that the lead density on the surface layer can be increased by more than 5 times. The plate grid produced by the production process can be applied to manufacturing of the electrode plate of the storage battery, the traditional thinking that the plate grid is made of pure lead or lead alloy is abandoned, the light conducting inner core is added to improve the performance of the grid plate, the using amount of the lead is reduced, the environment pollution is reduced, the weight of the storage battery can be reduced, and the volumetric specific energy and the discharge capacity of the storage battery can be increased.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a manufacturing process of a grid. Background technique [0002] The current lead electrode materials are mainly multi-element alloys with high lead content, such as lead-calcium-tin alloys, lead-calcium-silver alloys, lead-silver alloys, etc., which are not only heavy but also costly. [0003] In practical applications, the general direction of research and development is to try to improve the mechanical strength, electrical conductivity and corrosion resistance of electrodes by changing the composition of lead alloys. However, with the complexity of the alloy composition, the advantages of lead's own electrochemical performance will be weakened. [0004] There is also a part of the research and development direction to try to adopt the structural design of layered composite materials. For example, in the Chinese patent CN101092708A, an aluminum-lead layered composite mate...
