We present a facile strategy to synchronously exfoliate graphite and assemble high-quality graphene on 3D Ni(OH)2 surfaces. When serving as electrode materials for supercapacitors, the resulting 3D Ni(OH)2/graphene composites exhibited excellent specific capacitance, remarkable rate capability and super-long cycle life.
