Lithium–air battery

A lithium-air battery is a type of battery that uses lithium and oxygen from the air to create electricity. Inside the battery are special chemicals that allow it to take the lithium and mix it with oxygen from the air to create a reaction, which then creates electricity. This type of battery is very powerful and efficient, meaning it can produce more electricity with less weight and size compared to other types of batteries.
