Abstract
A high specific capacity spherical Li4Ti5O12 anode material of Lithium-Ion battery was successfully synthesized by a high-temperature solid-phase method consisting of ball milling, spray drying and calcination processes. Its suitable reaction conditions were explored by the orthogonal experiment method, and the effect of glucose addition on the morphology and electrochemical performance of Li4Ti5O12 was studied. The addition of glucose could change the surface structure of Li4Ti5O12, improve its conductivity, therefore enhance its electrochemical performance. The prepared lithium titanate represents a superior specific capacity of 163 mAh·g−1 at 0.2 C rates, approximately 65 mAh·g−1 under 10 C rates, and the capacity retention rate of sample remained 97.55% after 100 cycles of charging/discharging process.
