A high-performance crystalline Ti2O1.3(PO4)1.6/TiO2 carbon-coated composite as an anode for lithium-ion batteries

Abstract

A crystalline Ti₂O_1.3(PO₄)_1.6/TiO₂ carbon-coated composite was synthesized by a glucose-modified hydrothermal method. It shows the highest reversible capacities, excellent rate properties and remarkable cycling performances compared to its counterpart prepared without glucose modification, particularly maintaining a capacity of 233.9 mA h g⁻¹ after 200 cycles at 1000 mA g⁻¹.
