Embodiment Construction

[0073] The present invention adopts the combined process technology of "physical vapor deposition-electrodeposition-heat treatment", adopts the patented technology and special equipment for continuous production of strip-shaped non-metallic materials, and manufactures continuous and uniform lead cloth grids. Since the system is equipped with an online control surface density The device can precisely control the mass density of lead or lead alloy in the optimal range. Surface density error ≤ ± 30g / m, which is conducive to ensuring the consistency of electrode and battery performance. The lead consumption of the grid is reduced, and the weight specific energy of the battery is increased. The combined technology of "Physical Vapor Deposition (PVD)-Electrodeposition-Heat Treatment" is used to prepare continuous and uniform lead-cloth battery grids with an amplitude of 0.3-1.2m and a continuous length of 2-300m. Or a sheet-like lead cloth grid with a width of 0.3-1.2m and a length...

Abstract

A method and its equipment to manufacture the polar plate grid of lead-acid battery use the combined process of physical vapor phase deposition-electrodeposition-heat-treatment to produce the continuous and uniform lead-cloth grid with the equipment that can produce nonmetallic material in belt shape continuously. The said physical vapor phase deposition process includes one or two combination ofsputtering plating, evapouration plating and ion plating. The single metal lead or tin or lead and tin alloy is plated on the nonmetallic belt material.

Description

Technical field: [0001] The invention relates to a battery material, in particular to a manufacturing method and equipment for a lead-cloth battery plate grid Background technique [0002] A new type of lead-acid battery that has emerged in the battery industry in recent years is called a lead cloth battery or a horizontal battery. The base material of the plate, the grid, is also called lead cloth. Core, cold extruded lead to prepare lead wire, and then spun into a net, welded tabs and then shaped. The lead cloth manufactured by this weaving method has poor uniformity, and the surface density error is generally ≥60g / m. Although the amount of lead used is lower than that of the cast grid of traditional lead-acid batteries, there is also the problem that the amount of lead used in the grid is too high. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve the problems of poor uniformity, large surface density error, and...
