In situ growth of heterostructured Sn/SnO nanospheres embedded in crumpled graphene as an anode material for lithium ion batteries

Abstract

The in situ growth of Sn/SnO heterostructured nanospheres embedded in crumpled graphene is based on a new strategy for the calcination of tin oleate coating on the crystal surface of sodium carbonate. Sn/SnO nanospheres and crumpled graphene are acquired simultaneously without external forces involved. The obtained composite exhibits superior electrochemical properties when used as an anode material for lithium-ion batteries.
