▎ 摘 要
Ultra thin TiO2 layer (2 nm)-coated SnO2 nanotubes (NTs) wrapped by reduced graphene oxide (rGO) sheets (SnO2@TiO2@rGO) were synthesized as high capacity anode materials for lithium-ion batteries. The rationally designed anodes exhibited superior rate capability while maintaining a high discharge capacity of over 840 mA h g(-1) at a current density of 500 mA g(-1) after 50 cycles.
