焙烧温度对溶胶-凝胶法制备磷酸钒锂的性能
Influences of roasting temperature on performance of lithium vanadium phosphate synthesized by sol-gel method
摘要
Abstract
A sol-gel method was adopted to prepare Li3V2 (PO4)3 with citric acid as chelator and C sources. The electrochemical and physical performance of the products was characterized through galvanostatic charge-discharge tests, XRD and SEM. The results show that general electrochemical properties of Li3V2 (PO4)3are influenced by roasting temperature. The materials prepared at 700 ℃ have better electrochemical properties with the first discharge specific capacity of 105.6 mAh/g and capacity retention of 99.0% after 10 cycles. As-synthesized materials have well developed crystal structure and uniform grain distribution.关键词
