以Fe2O3为原料通过水热-高温煅烧法合成LiFePO4/C纳米复合材料及其电化学性能研究
LiFePO4/C Nanocomposites Synthesized from Fe2O3 by a Hydrothermal Reaction-calcination Process and Their Electrochemical Performance
摘要
Abstract
LiFePO4 nanoparticles coated with a carbon layer were synthesized by a hydrothermal reaction-calcination process,using Fe2O3 as an iron source and ascorbic acid as carbon source.The amount of ascorbic acid have an effect on the structure,phase and carbon amount of the final product.With 1 g ascorbic acid used in the reaction,the particle sizes of synthesized LiFePO4/C nanocomposites are in a range of 220-280 nm.Using as the cathode materials for the lithium-ion batteries,the as-prepared material shows high capacity and good cycle stability (159 mAh/g at 0.1C over 500 cycles),as well as good rate capability.关键词
