A nanocrystalline structured NiO/MnO2@nitrogen-doped graphene oxide hybrid nanocomposite for high performance supercapacitors

Abstract
A nanocrystalline NiO@MnO2/NGO hybrid composite electrode showed specific capacitance of 1490 Fg−1 at a current density of 0.5 Ag−1 and retains 98% up to 2000 cycles indicating its good cyclic stability.
