Crystalline SnO2 @ amorphous TiO2 core-shell nanostructures for high-performance lithium ion batteries

Tin oxide (SnO2) is an attractive anode in lithium ion batteries (LIBs), but its applications have been significantly hampered by the huge volume change during the electrochemical cycling. In this work we demonstrate a rational design of crystalline SnO2 @ amorphous TiO2 core-shell nanostructures, where the crystalline SnO2 core was synthesized by a hydrothermal method and the amorphous TiO2 shell was deposited by atomic layer deposition. The...
