A team of researchers has developed a cheap, and battery that could be used to store at power plants for a rainy day. Led by Sri Narayan, professor of chemistry at the USC Dornsife College of Letters, Arts and Sciences, the team developed an air-breathing battery that uses the chemical generated by the oxidation of iron plates that are exposed to the oxygen in the air – a process similar to rusting. “Iron is cheap and air is free,” Narayan said. “It’s the future.” Details about the battery will be published July 20 in the Journal of the Electrochemical Society.
