%X Nanocrystalline LiTi2(PO4)3/C has been synthesized by employing a solvothermal process in which oxalic acid was used as a solubilizer for the titanium source, a surfactant, and a carbon source. Additionally, Pechini's sol–gel-based method was also used as the synthesis method for comparison. LiTi2(PO4)3/C prepared by using a solvothermal route showed a homogenous particle size with spindle-like microstructures formed from self-assembled nanosized-platelets, whereas preparation by the sol–gel process resulted in agglomerated powders with irregular morphology and particle size. The different morphologies of LiTi2(PO4)3/C prepared in the two synthesis methods tend to form different electrode layer structures, which results in remarkable differences in their electrochemical properties. In particular, the solvothermally synthesized LiTi2(PO4)3/C composite exhibits superior high-rate-discharge capability and cycling stability. A capacity of approximately 97.7 % of the initial capacity was maintained for the solvothermal sample after 500 cycles at 5 C.
