Under the trend of lightening and thinning, PET composite copper/aluminum foil can achieve a composite current collector with a thickness of less than 8 μm, which plays an important role in the lightweight of power batteries. Power battery has large market demand and there are so many excellent power battery companies.
Ultra-thin copper–aluminum composite foils with a copper layer thickness ranging from 0.5 to 7 μm and a minimum square resistance of 4.6 mΩ can be prepared with a mass of 36.7 %-70 % of that of pure copper foils of the same thickness. These foils are expected to be used in a variety of energy storage components that require extreme lightweight. 1.
The microstructure of the copper–aluminum composite foil is smooth and dense, the minimum thickness of copper plating is only 0.5 μm, the adhesion of the copper cladding layer reaches ASTM 5B standard, and the peeling performance and the electrical conductivity is excellent.
At the same time, the raw material price of aluminum is much lower than that of copper, which can lead to a reduction in the raw material cost of the battery. Therefore, copper–aluminum composite foils are expected to be applied in the energy storage field that prioritizes high energy density and lightweight over excellent cycling performance.
Evaluation of physical, mechanical, and microstructural specifications of the cellular copper-aluminum composite materials. Lightweight cellular composite materials with high porosity of 88% with the incorporation of Al and polyethylene glycol. Uniform pore distribution of the cellular composite materials with a pore size of 200 μm.
3.5. Lithium-ion battery performance of copper–aluminum composite foils Here, we used 6 μm copper–aluminum composite foil and 6 μm commercial electrolytic copper foil as the anode collector of lithium-ion battery. Graphite was used as the anode material and made into a slurry, which was then coated on the two collectors respectively.
