Abstract

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 103.71mAhg−1 at 20C 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‖Li4Ti5O12, is also presented and discussed. [Copyright &y& Elsevier]

Abstract

The title composite is prepared from mixtures of V2O5, Li2CO3, NH4H2PO4, and meso-tetraphenyl porphyrin as the carbon source (350 °C for 4 h followed by sintering at 800 °C for 8 h in N2 atmosphere). [ABSTRACT FROM AUTHOR]
