A freestanding composite film electrode stacked from hierarchical electrospun SnO2 nanorods and graphene sheets for reversible lithium storage†
Abstract
A freestanding hierarchical SnO2 nanorod/graphene composite film electrode was designed and fabricated by a general route involving electrospinning and film casting processes. With dual adaptable strategies (hierarchical nanorod structure and graphene “overcoats”), the composite film electrode exhibited enhanced cycling stability.
