Abstract:	An energy storage device reaching energy densities of 102 Wh/Kg at power densities of 10 W/Kg would mean the possibility of charging such a device in 36 s. The nanocarbon device presented here is closer to that feat than any previously reported system. N-doped Carbon Nanopipes were used as anode and Partially Reduced Graphene Oxide as cathode, with LiPF EC/PC electrolyte. This system yields simultaneously high energy and power densities (262 at 450 W/kg and 78 Wh/kg at 9000 W/kg) which are energy/power combinations considerably higher than those of present Li-ion batteries. Our cell exhibits excellent cycle stability (∼91% capacity retention after 4000 cycles "0. 01-4 V"). These breakthrough results are based on the kinetic balancing of the nanocarbon electrodes, which can deliver excellent high energy density at high rates and low costs.
