Novel mesoporous TiO2 spheres as anode material for high-performance lithium-ion batteries

Abstract Mesoporous TiO 2 spheres are successfully synthetized as high performance anode materials for lithium-ion batteries. The obtained mesoporous TiO 2 spheres exhibit excellent rate capability and good cycling stability, which shows initial discharge capacity of 315 mAh/g and remains 208 mAh/g after 150 cycles. This improved electrochemical performances of TiO 2 spheres is ascribed to the synergetic effects of their unique sphere structure and mesopore structure.
