Functional carbon materials with a combination of 0 dimension and 2 dimension are particularly interesting in the electrochemical field owing to the low density, high surface area, and strong ion-bearing capacity. Especially, hollow mesoporous carbon spheres (0 dimension) and nanosheet (2 dimension) composite hollow porous carbon spheres and nanosheet (
HMCS
/S) have received much attention as electrochemical capacitor electrode materials. However, it is challenging for effective preparation of this complex composite structure. In this work, a novel and simple procedure to prepare N-doping
HMCS
/S (N-
HMCS
/S) is presented. This approach adopted silica spheres as the core and employed [C
18
Mim]Br and tetraethyl orthosilicate as the structural directing agent for the formation of the flaky/spherical hybrid structure. The unique structure of nanosheets embedded by hollow carbon spheres and N-doping characteristics endow N-
HMCS
/S with good performance in electrochemical capacitor with high specific capacity (196.5 F g
-1
) in the three-electrode system and excellent high-rate capability with retention of 61.5% in the two-electrode system.
