Synthesis and Electrochemical Performances of Li₄Ti₅O₁₂/C as Anode Material for Lithium-Ion Batteries

Abstract:

Spinel Li4Ti5O12 exhibits inadequate electronic conductivities that negatively impact its electrochemical performance, this disadvantage limits its commerical use in high current applications for future hybrid electric vehicles. Li4Ti5O12/C has been examined in order to improved the electronic conductivities. Different sucrose additions at m(sucrose)/m(Li4Ti5O12) = 5%, 10%, 15% are investigated along with the structure and electrochemical performances. The results show that the best sucrose addtion is 10%, when sintered at this condition, the distribution of particles size and electrochemical performance of the compound are the most satisfying. When charged at 0.5 C, the initial discharge capacity is 167.72 mAh•g-1, and the initial charge capacity is 162.28 mAh•g-1, and it shows the longest and flattest discharge performance among the three synthesized samples.
