The Effect of Temperature on the Morphology and Electrochemical Performance of Li₃V₂(Po₄)₃ Cathode Material

Abstract:

Li₃V₂(PO₄)₃ cathode materials were synthesized by a sol-gel method. The effect of sintering temperature on the morphology and electrochemical performance of Li₃V₂(PO₄)₃ product was studied. XRD, SEM and galvanostatic charge/discharge tests were used to analysis the structure and electrochemical performance of Li₃V₂(PO₄)₃ materials. The results indicate that 800 °C was a suitable temperature to synthesize Li₃V₂(PO₄)₃ materials. The product synthesized at that temperature has more uniform particle and shows higher capacity than other materials.
