A novel 3D hierarchical mesoporous Co 3 O 4 structure assembled by ultrathin nanoflakes (2.4 nm in thickness) has been successfully developed. Combining a high specific surface area (183.8 m 2 g –1 ), mesoporosity, and a stable 3D hierarchical structure render the as‐synthesized 3D Co 3 O 4 the properties of a promising active material for high‐rate pseudocapacitors with high specific capacitance, excellent rate capability, and durable long‐term stability.
