In this work, NiCo 2 S 4 nanocages are successfully fabricated by a template‐engaged route for pseudocapacitor applications. The NiCo 2 S 4 nanocages exhibit a high capacitance (1635 F g −1 at 1 A g −1 ) and a good rate capability (50 % capacitance retention at 16 A g −1 ). The superior electrochemical performances can be attributed to the high conductivity of NiCo 2 S 4 as well as the hollow structure. This effective strategy shows the feasibility of designing and fabricating metal sulfides with hollow structures as electrode materials for high‐performance supercapacitors.
