Scientists at the University of St. Andrews in Scotland have developed the world’s first battery fueled by air. This battery has 10 times the storage capacity of conventional batteries and could pave the way for changes and innovations in things like mobile phones, laptops and electric cars. It’s much lighter than current batteries as the main chemical in traditional batteries, lithium cobalt oxide, is replaced with carbon and oxygen. This also helps to recharge the battery as it’s used, perhaps signifying the death of the phrase, “my battery’s dead”. Professor Peter Bruce of the Chemistry Department at the University of St Andrews, said in the Telegraph: “The benefits are it’s much smaller and lighter so better for transporting small applications… Storage is also important in the development of green power. You need to store electricity because wind and solar power is intermittent.”
