Electrochemical performance of porous α-LiVOPO4/C composite by solution combustion synthesis method

Porous α-LiVOPO4/C composite was prepared by the solution combustion synthesis method followed by annealing at 500°C for a short annealing duration of just 50 min. The synthesised material was characterised by XRD, SEM, TEM, N2 adsorption–desorption isotherms and charge–discharge tests. When tested at 0.05C rate for Li ion insertion properties, α-LiVOPO4/C composite exhibits good cycle capability with an negligible capacity degradation for the first 31 cycles. However, it shows poor rate capability with initial discharge specific capacities of 127.6 mAh g− 1 (0.05C), 109.1 mAh g− 1 (0.1C) and 74.9 mAh g− 1 (0.2C), respectively.
