Enhanced supercapacitor performance of NiCr–LDH nanosheets supported on exfoliated nano-graphite flakes by a one-step cathode glow discharge electrolysis strategy

A flower-like NiCr–LDH/graphite nanocomposite is fabricated by CGDE strategy. The nanocomposite exhibits 2577.3 F g −1 specific capacity. The NiCr–LDH/graphite//AC shows 44.37 Wh kg −1 energy density and 91.2% capacity retention after 10 000 cycles.
