Abstract

Spinel LiMnTiO₄ as the cathode material for Li-ion batteries has been synthesized by a sol–gel method. The LiMnTiO₄ cathode possesses two voltage plateaus, and exhibits an initial discharge capacity of 203.3 mAh g⁻¹. After 47 charge–discharge cycles, the capacity retention of the LiMnTiO₄ cathode is 77.5 %, which is much higher than that of LiMn₂O₄ (47.9 %). Ti substitution can successfully suppress the formation of tetragonal phase during cycling and hence increase the structural stability; however, it decreases the discharge capacity. Multi-walled carbon nanotubes (MWCNTs) were mechanically milled with the pristine LiMnTiO₄. The as-prepared LiMnTiO₄/MWCNTs composite electrode exhibits significantly improved electrochemical properties including rate capability and cycling stability, as compared with LiMnTiO₄.
