Layer-by-layer self-assembly of a sandwich-like graphene wrapped SnOx@ graphene composite as an anode material for lithium ion batteries

Sandwich-like hybrid nanosheets consisting of graphene wrapped SnO/ SnO2 nanocrystals anchored on graphene have been synthesized via a facile layer-by-layer self-assembly approach. The hierarchical structure exhibits good cyclability and rate performance benefiting from the unique double protection of graphene layers.
