The Synthesis and Electrochemical Performance of LiV₃O₈ Cathode with Lanthanum-Doped

Abstract:

Li_1-xLa_xV₃O₈ cathode materials has been synthesized by pechini sol-gel method. The electrochemical performances of Li_1-xLa_xV₃O₈(x=0-0.05) have been studied by X-ray diffraction (XRD), galvanostatic charge-discharge, and cyclic voltammetric (CV). The results showed that the optimal content of the La³⁺ doping in LiV₃O₈ was x=0.01, and the first discharge capacity of Li_0.99La_0.01V₃O₈ sample in the voltage range of 2.0-4.0V was 230mAhg^-1, which was much higher than that of LiV₃O₈ (200mAhg-1). The Li_0.99La_0.01V₃O₈ cathode also showed higher discharge voltage plateau than LiV₃O₈ cathode from the CV curves.
