Structure and Application Copper foil soft connection is made up of multiple pieces of T2 purple copper foil stacked and welded to both ends. Drilling can be carried out according to customer requirements. Molecular diffusion welding is a precision welding technology that promotes mutual diffusion and bonding between atoms of a workpiece under high temperature and pressure conditions. A high-strength joint is formed while maintaining no visible deformation of the workpiece.
Therefore, copper foil soft connection is an excellent electrical conductor and is usually used in related industries such as new energy vehicles, wind power generation, photovoltaic energy storage, electric locomotives, and complete transmission and distribution.
Customized production can be customized based on customer drawings/samples and provided systematic service support
Specifications & Applications
This automotive battery soft connection uses high-purity T2 copper foil (>99.95% Cu) and pressure welding (molecular diffusion welding) at both ends. The welded joint is free of filler metal and stress concentration, giving excellent fatigue resistance under road vibration. Single-foil thickness is normally 0.10 mm; dimensions, cross-section and plating (tin/nickel/silver) are built to drawing or sample. Layer count and width are tuned to your pack’s rated current and available envelope for a reliable, low-resistance link.
Material reports and RoHS-compliant copper are available. We support sample orders and flexible MOQ. Send your drawing for a fast quote.
Automotive battery soft connection: Excellent performance of press-welded copper foil soft connection at both ends
Today, with the increasing popularity of new energy vehicles,car batteryConnection technology is particularly important. We focus on providing high-qualityAutomotive battery soft connectionSolutions, especially adoptingBonded copper foil at both endsSoft connection products manufactured by the process are designed to provide a more stable, efficient and safe connection for your battery system.
What is a soft connection with crimped copper foil at both ends?
Soft connection of copper foil bonded at both endsIt is a conductive part that uses advanced pressure welding technology to firmly connect multiple layers of thin and soft copper foils at both ends through a high-pressure welding process. This unique structure gives it excellent flexibility and electrical conductivity, making it play a key role in automotive battery modules and battery packs.
Product characteristics and advantages
excellent conductivity: The extremely high purity copper foil material ensures extremely low resistance, effectively reduces energy consumption, and improves battery charging and discharging efficiency.
Excellent flexibility and vibration resistance: The multi-layer copper foil structure gives it excellent bending and twisting capabilities, which can effectively absorb vibration and displacement generated during driving, avoid stress concentration, thereby extending the service life of batteries and connections.
high current carrying capacity: After special pressure welding process, the connection points are tight and reliable, can carry large currents, and meet the high power output needs of new energy vehicles.
High temperature and corrosion resistance: High-quality copper materials and precise manufacturing process enable the soft connection to maintain stable performance in harsh working environments and effectively resist high temperatures and chemical corrosion.
Easy installation and low maintenance costs: Standardized design and flexible features make the installation process simple and quick, while reducing failures caused by connection problems and reducing later maintenance costs.
customized services: We can provide customized products with different lengths, widths, thicknesses and hole position designs according to customers ‘specific needs, perfectly matching various battery modules and systems.
