Facile preparation of free-standing rGO paper-based Ni–Mn LDH/graphene superlattice composites as a pseudocapacitive electrode.

A novel film electrode was assembled via a simple filtration process, with an rGO paper as the substrate and Ni–Mn LDH/graphene superlattice composites as the functional layer. The electrode presented typical pseudocapacitive behaviours with excellent rate property and cycle stability. [ABSTRACT FROM AUTHOR]
