Metal–organic framework induced hybrid NiCo2S4/PPy structures with unique interface features for high performance flexible energy storage devices

In this work, we report hybrid-structure NiCo 2 S 4 /PPy nanosheets through hydrothermal synthesis and electrodeposition methods. Meanwhile, the NiCo 2 S 4 /PPy-110 samples exhibit a high specific capacitance of 983 C g −1 at 1 A g −1 and excellent stability.
