Can aluminum be used to make new types of batteries?

Yes, aluminum can be used to make new types of batteries. Aluminum-air batteries, for instance, are a type of metal-air battery that uses aluminum as the anode and air as the cathode. These batteries have a high energy density and are lightweight, making them suitable for certain applications like electric vehicles and backup power systems. Research is ongoing to improve the efficiency and lifespan of aluminum-based batteries, addressing issues such as aluminum corrosion and the development of efficient air cathodes.
