Li3V2(PO4)3/Li4Ti5O12锂离子全电池的循环伏安性能
Cyclic voltammetry performance of Li3V2(PO4)3/Li4Ti5O12 full lithium-ion battery
摘要
Abstract
Investigates the cyclic voltammetry(CV)performance of Li3V2(PO4)3/Li4Ti5O12 full lithium-ion batteries within voltage window of 1.5～2.9,1.5～3.3 V.The experimental result reveals three distinct pairs of redox peaks at 2.06/1.99,2.15/2.06,2.57/2.44 V,with voltage differences of 0.07,0.09,0.13 V respectively in the 1.5～2.9V interval,which indicates increasing polarization effects with rising voltage.In the voltage window of 1.5～3.3 V,four oxidation peaks(2.06,2.15,2.58,3.01 V)and three reduction peaks(2.42,2.05,1.98 V)are observed.The appearance of the fourth oxidation peak corresponds to the third-stage lithium deintercalation process of the Li3V2(PO4)3 cathode material.The study provides important references for the optimization of the electrochemical performance of full batteries that Li3V2(PO4)3 matches with other anode materials.关键词
