Combination the materials together is a direct and forceful strategy to improve the electrochemical properties of each raw material. Herein, we present the method of hydrothermal process and treatment/calcination combination that is easy to synthesize a NiCo 2 O 4 nanoparticles‐mesoporous carbon composite (C/NiCo 2 O 4 ). The result study electrochemical properties of materials revealed that the C/NiCo2O4 composite has excellent electrochemical properties compare with pristine NiCo 2 O 4 or carbon. In particular, maximum specific capacitance of C/NiCo 2 O 4 material at a current density of 1 A.g −1 is 204.28 F.g −1 , meanwhile the C s of carbon and NiCo 2 O 4 are 25.06 F.g −1 and 178.78 F.g −1 , respectively. In addition, C/NiCo 2 O 4 material also showed excellent capacitance retention, C s maintained to 90.35% after 3000 charge‐discharge continuous cycles. The results show that the C/NiCo 2 O 4 is a promising material for application as supercapacitor electrode.
