Al metal is one of the most attractive anode materials in post-lithium batteries in view of its numerous merits, such as low cost and high Earth abundance, as well as high charge density and gravimetric/volumetric capacities, compared with Na, K, and Zn (Fig. 1a and Supplementary Table 1) 10, 21, 24, 25.
For battery, a piece of titanium foil coated with CuS (1 × 1 cm 2) is used as cathode, and LiAl is used as electrolyte. Aluminum foil is used as anode firstly. However, the aluminum foil is corroded spontaneously in the LiAl, as shown in Fig. S5.
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.
Nature Communications 13, Article number: 576 (2022) Cite this article Aqueous aluminum batteries are promising post-lithium battery technologies for large-scale energy storage applications because of the raw materials abundance, low costs, safety and high theoretical capacity.
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.
