Embodiment Construction

[0073] The invention adopts the combined process technology of "physical vapor deposition-electrodeposition-heat treatment", and adopts the patented technology and special equipment for continuous production of strip-shaped non-metallic materials to manufacture continuous and uniform lead cloth grids. Because the system is equipped with an online control of surface density The device can accurately control the mass density of lead or lead alloy in the optimal range. Area density error≤±30g / m 2 The lead consumption of the grid is reduced, and the weight of the battery is increased. Using the combination technology of "physical vapor deposition (PVD)-electrodeposition-heat treatment", a continuous and uniform lead cloth grid of lead cloth battery is prepared, the width of the lead cloth grid is 0.3-1.2m, and the continuous length is 2-300m. Or sheet-shaped lead cloth grid with a width of 0.3-1.2m and a length of 0.3-2m.

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 method and equipment for manufacturing a lead cloth battery 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 electrode plate, a grid, is also called lead cloth. Its manufacturing process currently uses glass strands as the thread. The core is cold-extruded to prepare the lead wire, which is then spun into a net and welded to form the lug. The lead cloth manufactured by this weaving method has poor uniformity and the areal density error is generally ≥60g / m 2 . Although the amount of lead is lower than that of the cast grid of traditional lead-acid batteries, there is also the problem of excessive lead in the grid. Summary of the invention [0003] The technical problem to be solved by the present invention is to solve the problems of poor u...
