Copper-aluminum composite connecting piece for lithium battery
With the rapid development of the lithium battery automobile industry, the PACK connection problem of lithium batteries is becoming increasingly prominent, which seriously restricts the safety of lithium ion batteries.
Thousands of batteries are installed on lithium battery electric vehicles, and the anode materials of single cells are aluminum foil and copper foil. How to achieve a safe, reliable, lightweight, simple string and parallel connection of lithium battery packs is a bottleneck technology that restricts the development of lithium battery vehicles.

Through independent innovation, our company has developed several kinds of copper-aluminum composite materials for lithium batteries. Cu-Al composite pillar material and Cu-Al composite transition sheet.
Base pillar material: a 3mm copper strip and a 10mm aluminum solution are combined into a copper-aluminum composite base material to complete the copper collector connection of the copper negative electrode, while aluminum and the outer aluminum plate are connected to form the battery pack. Aluminum, can be connected using normal laser welding process;
Material of connection piece: A copper strip with a thickness of 10mm is compounded in the middle of the aluminum plate. The copper strip is connected with the copper keel through copper rivets.

The product introduction is as follows:
Product size: customized according to user needs.

COPPER CLAD ALUNINUM PLATE/ STEEL CLAD STEEL PLATE/ COPPER CLAD STEEL PLATE/ TITANIUM CLAD STEEL PALTE /ALUNINUM CLAD STEEL PLATE FOR Transition joint plate block
The copper and aluminum are excellent conductive materials with high cost performance. They are widely used in power systems and are the main conductive materials.In general, the aluminum is used in the high voltage line, and the copper is used in low voltage distribution cabinet systems.However, the copper and aluminum cannot be directly connected. Therefore,the reliable connection between copper conductor and aluminum conductor has a significant impact on the safe operation of the whole power system.
The traditional copper-aluminum connecting materials are usually prepared by the flash welding, friction welding and brazing processes. There is the quality risk and the potential safety hazard for the mechanical properties, reliability and electrical conductivity of the connectors.It is imperative to develop an advanced production technology and a new type of electric fittings materials.
Our company develops the copper clad aluminum composite equipment clamp, parallel groove clamp, copper clad aluminum composite transition plate and copper clad aluminum composite connecting sheet by the independent innovation. They are widely used in the electric industry for the replacement of the traditional process, to not only improve the product quality, but also reduce the production cost. Therefore, it is an ideal connecting products of copper clad aluminum transition plate.

COPPER ALD ALUNINUM PLATE FOR CONDUCTIVE BUSBAR
Product Size
Thickness3.0~15.0mm;Width≤500mm.
Product Features
The copper clad aluminum composite bars produced by our company with several patented technologies solves two major problems of copper clad aluminum composites, such as easy oxidation of copper and aluminum, difficult removal of oxide film, and inter metallic compound (Al2Cu) between copper and aluminum at lower temperature. The thickness of copper-aluminum transition layer for the traditional copper clad aluminum bar is 15 - 50μm through the SEM analysis, while the thickness of copper-aluminum transition layer for the copper clad aluminum composite bar produced by our company is only 1-2um, which is much less than that of traditional copper clad aluminum bar. It not only realizes the metallurgical bonding between copper and aluminum, but also ensures the bonding strength between copper and aluminum effectively, to solve the problem of high resistivity for the transition layer. Its overall performance is excellent, the bending, drilling and punching performance are the same as that of pure copper, and the density is small, and it can save more than 30% of cost in use.

Electric conductivity industry (can be widely used in high and low voltage distribution cabinet, switch gear, bus-bar and electrolyzer).

 

Titanium clad copper bus bars is a copper bar cladding with a certain thickness of titanium level, mainly used as a stand in plating, electrolysis, hydrometallurgy processes, because it has not only the original conductive property of the copper bar, but also protecting the copper bar from corroded by titanium level, therefore avoid the traditional copper bus bars shortcomings: danger and difficulty changing the anode metals, copper bar corrosion, heat generation caused by the electrical contact resistance in electrolysis and plating defects due to corroded and fallen copper compound, can greatly lower pollution of electrolyte. Now, the submerged Ti clad copper bus bar is the best choice for many industries including print circuit makers, steel (copper, gold) refining manufacturers.
 
Normally, we provide the first rate clad non-ferrous metal composites, mainly titanium clad copper and also including zirconium clad copper, 316L steel clad copper, titanium clad 316L steel plates, bars, tubes, composite wire, and multi-layer clad composites, etc. 
 
But, if you request that the material has this function above, then you must be sure that there are much stronger combination strength and much higher pasting rate between the copper bars and the titanium level, this can't be met by traditional mechanical combination methods. So in order to overcome it, our company R&D team summarizes three advanced processing technologies through several ten years of experiment: explosive welding, rolling cladding, and explosions-rolling cladding. Elegant group has successfully produced four individual layers titanium clad copper bars, at minimum, there is a core and an outer layer. Its sheared strength ≥ 130 Mpa, compact rate ≥ 98%, we can also supply the various specification of round, square, flat bars, the length of the bars can reach above 10 meters and can weld different shape and material together in according to the customer request. We could also make nickel clad copper bars, stainless steel clad copper bars, and zirconium clad copper bars series products through the same process technology.
 
Unsurpassed advantage performance of Titanium Clad Copper bus bar anode: 
(1) Good Shear and tensile strength: The shear and tensile strength is tested and guaranteed in accordance with GB, ASTM, and JIS.
(2) Perfect Elongation and Ductility: Elongation and Ductility of cladding metal is guaranteed in face bend (=cladding metal in tension), and the ductility of base metal is guaranteed in reverse bend (=cladding metal in compression).
(3) Good Hardness: The bonded interface is slightly hardened after explosion bonding. The interface can be softened by heat treatment to an original level. There exists no difficulty in bending and drawing works
(4) Excellent electrical conductivity: explosions-rolling process of the production make titanium and copper composite close completely with no delamination and therefore has good electrical conductivity, the composite strength of 135Mpa, and micro-resistance for 7.77 × 10-6Ω
(5). Fantastic Corrosion Resistance: Explosion bonding, a clad processing, guarantees excellent corrosion resistance of clad materials.
