Fabricante líder de conectores de barra colectora de batería personalizados

We use a composite process of laser spot welding and ultrasonic welding, which reduces the connection resistance to less than 0.15 mΩ. The lower buffer structure can increase the stress dispersion efficiency of the welding point by 40%, and the cycle life exceeds 5,000 times of charging and discharging tests. The technology has been applied to the 150 kWh solid-state battery pack of the Azalea ET7, realizing the temperature difference of the single cell to be controlled at ±1.5℃.
Cross-border integration of material science. The use of high-purity oxygen-free copper (purity ≥99.99%) with nanoscale nickel plating technology has increased the electrical conductivity to 102% IACS (International Annealed Copper Standard), while the salt spray resistance test has exceeded 2,000 hours. The copper-graphene composite material developed by AVIC Optoelectronics maintains conductivity stability under the working conditions of -40℃~150℃ and is successfully applied in the Tibetan Plateau Energy Storage Project.
