Can aluminum be used to make batteries?

Yes, aluminum can be used to make batteries. Aluminum-air batteries are a type of metal-air battery where aluminum serves as the anode and undergoes oxidation. These batteries have a high energy density and are environmentally friendly, as they produce minimal waste. However, they face challenges such as water sensitivity and the need for alkaline electrolytes, which limit their practical applications. Research is ongoing to improve their performance and make them more viable for widespread use.
