We developed a stacking-free nitrogen-doped graphene network (NGW) for high performance capacitive energy storages. We overcame the commonly occurring rGO stacking problem during the hydrothermal process by the intercalation of CNTs and g-C3N4 with functional groups to react with rGO sheets, creating a well-organized carbon network. The NGW exhibited a great energy density of 36.0 Wh/kg at a power density of 1496.1 W/kg, and the nearly 100 % capacitance retention after 10,000 cycles. Our approach suggests a new strategy to address the staking issue of reduced graphene oxide-based materials for practical energy-storage systems.
