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 gâ1 at 20 C charge/discharge rate. The Li+ diffusion coefficient ranges from 10â9 to 10â10 cm2 sâ1 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)3âLi4Ti5O12, is also presented and discussed.
