Hybrid at either the mechanism or the device level can lead to a hybridization effect to the kinetics and electrochemical characteristic of a SC. Herein, a heterostructured NiCo2S4/CoxNi1‐x(OH)2 battery‐like cathode material was designed, from which the obtained sample accomplished the combination of excellent electronic and ionic conductivity so as to realize an enhanced faradaic redox storage process. Besides, a SC‐typed highly capacitive anode material of a N and S co‐doped porous carbon nanosheet (ACNS) was also fabricated, which exhibits great advantages in its enlarged specific surface areas, easy to introduce pseudocapacitive reactions and physical structures. These features would directly lead to the significant improvements in the EDLC‐typed electrochemical properties of the carbon anode. The combination of EDLC‐typed carbon anode with the redox reaction‐typed cathode in a full cell device would potentially lead to the charge storage process simultaneous integrates the electrophysical and electrochemical process. Due to these reasons, the obtained solid‐state hybrid SC delivers a wide voltage window of 1.6 V, a high specific capacity of 121.3 C g‐1, an enhanced energy/power density of 26.1 Wh kg‐1/11 kW kg‐1. The as‐assembled device can keep high and stable capacity retention of 89.1% for over 10,000 cycles. The developed hybird assembled strategy and the electrode combination may provide design guidelines for designing other high‐energy hybrid SC.
