| Abstract |
Lithium-ion batteries are the most important energy storage system for wide applications in electronic portable devices and hybrid electric vehicles. Lithium ion battery consists of four major components such as anode, cathode, electrolyte, and the separator. During the charging process, lithium ions are released from the cathode and transferred to anode through the electrolyte, and this process is reverse during the discharge process. As a cathode material of Li-ion battery, typical vanadium-containing phosphate, Li3V2(PO4)3 (LVP), has a high theoretical specific capacity of 197 mAh g-1 for the multiple valence state of the vanadium element. In addition, vanadium-contained phosphate has excellent thermal stability and contributing to good cycle stability during the charge and discharge processes. In this study, a lithium borovanadate system, which is a vanadium-contained borate, was prepared via sol-gel method. And its electrochemical properties of samples were investigated. The electrochemical properties of samples were investigated through lithium extraction/inserting processes using galvano-static charge/discharge and cyclic voltammetry (CV) measurements so as to investigate for Li+ ion transfer between the active electrode materials. |
