Product Description
DESCRIBE:
Lithium battery copper aluminum composite materials are currently our company's main product series, developed through independent innovation. improvement of capacity ratio.
With the rapid development of the lithium-ion battery industry and the contribution of the electric vehicle industry to the use of lithium-ion batteries, the PACK connection problem of lithium-ion batteries is becoming increasingly prominent. Even many electric vehicle companies such as BYD and Tesla have upper and lower battery packs for their entire buses.
The positive and negative electrodes of individual batteries are made of aluminum foil and copper foil. How to achieve reliable, reliable, lightweight, and simple series and parallel connection of lithium battery packs is a bottleneck technology that restricts the development of lithium battery vehicles. Our main production materials are to effectively solve this problem.
ADVANTAGE:
At present, the main composite materials used in two types of battery products are copper aluminum composite pillar materials and copper aluminum composite transition plate materials. The lithium battery materials we produce have the characteristics of high composite strength, high conductivity, no connection between copper and aluminum, high impact resistance, low cost, stable quality, light volume, corrosion resistance, and effective
Composite a 10mm copper strip in the middle of the aluminum plate, which is connected to the internal copper collector through copper rivets.
The aluminum plates on both sides complete the series and parallel connection between the individual batteries. Compared with the welding process, this product has the advantages of good seismic performance, high composite strength, no contact resistance between copper and aluminum, stable and reliable quality, and high mechanical processing performance and stable process.
High composite strength, achieving metallurgical bonding between copper and aluminum, with no contact resistance between copper and aluminum, ensuring stable and reliable quality.
SIZE AND PROFILE:
The copper aluminum composite pillar material is made by combining 3mm copper material and 10mm aluminum plate, completing the copper collector connection of the copper negative electrode, while the aluminum and outer aluminum plate are connected to form the battery pack. Both exposed electrodes are made of aluminum material, which can be connected using normal laser welding process. The copper aluminum composite pillar material is used to connect the copper ear of the negative electrode of the battery, while the aluminum is connected to the outer aluminum plate to form the battery pack. Both exposed electrodes are made of aluminum and can be connected using normal laser welding technology. It is our company's flagship product.
