New graphene breakthrough supercharges energy storage

Engineers developed a breakthrough carbon-based material called multiscale reduced graphene oxide that enables supercapacitors to store energy like traditional batteries while charging far more rapidly. The new material, created from abundant Australian graphite through innovative heat treatment, achieved record energy densities up to 99.5 Wh/L and power densities of 69.2 kW/L, potentially replacing batteries in electric vehicles and electronics applications.
