Mesoporous TiO2 Spheres/Graphene Composite as a High-Performance Anode Material for Lithium-ion Batteries

Abstract

Mesoporous TiO 2 spheres/graphene (TOS/G) composites were successfully prepared via a UV-assisted method of reduced graphene oxide with hydrazine.The as-prepared TOS/G composites exhibit a high initial discharge capacity of 218 mAh g -1 and retain 86% of reversible capacity over 100 cycles at a rate of 0.2 C.
