Seven times higher energy density is the promise Japanese researchers at the University of Tokyo are working towards. Through adding cobalt, they reached a oxidation-reduction reaction that sets off peroxide. The researchers expect an energy density of 2,570 Wh/kg if the idea is applied in real batteries at some point.
