Sulfate assisted synthesis of α-type nickel hydroxide nanowires with 3D reticulation for energy storage in hybrid supercapacitors

α-Type NSOH NWs with 3D reticulation were synthesized by a sulfate assisted hydrothermal reaction and exhibited a high capacity of 246.3 mA h g −1 at 1 A g −1 . The energy density of the NSOH NWs//AC HSCs is up to 59.8 W h kg −1 at 830.3 W kg −1 .
