Synthesis and Electrochemical Performance of LiV₃O₈/MWCNTs Cathode Material for Lithium-Ion Batteries

Abstract:

Layered LiV₃O₈ cathode material was prepared by sol-gel method using ethylene diamine tetra-acetic acid (EDTA) as chelon, and LiV₃O₈/MWCNTs composite materials were fabricated by mixing multi-walled carbon nanotubes (MWCNTs) and LiV₃O₈ particles via ball milling technic. X-ray diffraction (XRD), scanning electron microscopy (SEM), galvanostatic charge-discharge experiments were employed to characterize the material structure, morphology and electrochemical properties respectively. The results show that the layer structure of LiV₃O₈ did not change after doping MWCNTs, and the LiV₃O₈/MWCNTs composite showed excellent electrochemical performance. The initial specific discharge capacity of the 2% MWCNTs （mass percent） composites can reach 217.5 mAh/g at 0.1C discharge rate in the potential region 1.8-4.0V, and maintains a stable capacity of 224.9 mAh/g within 30 cycles. Comparing to the LiV₃O₈/MWCNTs, the capacity of pure LiV₃O₈ samples can only remain 86% intetial specific capacity at the same test conditions.
