Product Introduction

1. Material characteristics: It is manufactured using advanced vacuum melting technology, and after forging, rolling, annealing and drawing, it has low resistance, high conductivity, good welding performance and high tensile strength. Its pure nickel material makes it easy to weld, stable connection, and has good corrosion resistance and low resistance, which can effectively save energy and make the battery pack more powerful.
2. Size specifications: The thickness and size can be customized according to customer needs. The common thickness is 0.15mm and 0.2mm, and the width has a variety of options, such as 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 15mm, etc., which can also be customized according to specific needs.
3. Application areas: It is widely used in the manufacture of lithium-ion batteries, nickel-cadmium batteries, nickel-hydrogen batteries and other batteries, as well as the assembly of battery packs. These batteries are widely used in energy storage systems, new energy vehicles, electric bicycles, solar street lights, power tools and other industries.
4. Physical properties: It has good spot welding performance, low resistance, longer battery discharge time, and higher spot welding strength. Its high temperature tolerance and corrosion resistance enable it to maintain stable performance even in harsh environments.
5. Technical support: Equipped with imported stamping equipment and complete molds (more than 2,000 sets of battery industry hardware molds), we can independently open molds to ensure product accuracy and quality.
6. Product advantages: All materials are degreased and dry punching technology is used to ensure product cleanliness and reduce the workload of customers during battery pack assembly.
