▎ 摘　　要

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.
