▎ 摘  要

A novel approach to fabricate sandwich-like graphene-supported mesoporous SnO2 nanosheets (G-SnO2) as anode materials for lithium-ion batteries (LIBs) was developed. The obtained sandwich-like G-SnO2 inherit the typical two-dimensional structure of graphene and possess a high specific surface area (64m(2)g(-1)), nanosized SnO2 particles (about 3 nm in diameter), mesoporous structure (a pore size of mainly similar to 3.8 nm), large aspect ratio and enhanced electrical conductivity. As a consequence, the G-SnO2 anode significantly improved the LIBs capacity and cycle performance (536 mAh g(-1) at 500 mA g(-1) even after 500 cycles).
