Can we use aluminum in batteries?

Yes, aluminum can be used in batteries. It is commonly used as a current collector in lithium-ion batteries due to its low density, high conductivity, and corrosion resistance. Aluminum's role is primarily structural, providing support and facilitating the flow of electricity. However, it is not used as an active material in the electrochemical reactions that generate power. Research is ongoing to explore the potential of aluminum as an anode material in next-generation batteries, aiming to improve energy density and reduce costs.
