Abstract
High rate Li₃V₂(PO₄)₃/C composite with excellent electrochemical performance has been successfully synthesized via a sample carbon thermal method using meso-tetraphenyl porphyrin (TPP) as carbon source. The as prepared Li₃V₂(PO₄)₃/C composite delivers a reversible capacity of 103.71 mA h g⁻¹ at 20 C charge/discharge rate. The Li⁺ diffusion coefficient ranges from 10-9 to 10-10 cm² s⁻¹ based on different scanning rates. The excellent high rate performance may attribute to the small particle size of the LVP/C and the carbon derived from thermal decomposition of TPP. In addition, its application in the full-cell, Li₃V₂(PO₄)₃/C‖Li₄Ti₅O₁₂, is also presented and discussed.
