In this paper, the synthesis of composite Na1.2V3O8/LTX by sol-gel method was described. The synthesized powders were characterized by X-ray powder diffraction (XRD) and thermogravimetric analysis (TGA) while the electrochemical performances were investigated by cycling voltammetry (CV) by different scan rate. After thermal treatment, the part of carbon was 7%. The initial discharge capacity was 100.44 mAhg-1. The most capacity fade was after 2nd cycle (14%) but capacity fade from 6th to 10th cycle was only 10%. The efficiency of Na1.2V3O8/LTX is around 95%.
