Co doping enhances the pseudocapacitive performance of Ni3S4/NiS heterostructures for high-performance asymmetric supercapacitors

The poor conductivity and insufficient number of electroactive sites of nickel sulfide lead to unsatisfactory electrochemical performance. To address this issue, a Co-doped Ni 3 S 4 /NiS heterostructure (NixSy@Co) was prepared by hydrothermal method. Structural and electrochemica...
