NaF—M(M=Fe,Cu)钠离子电池转换正极材料的研究
NaF-M (M = Fe, Cu) Nanocomposites as Conversion Cathode Materials for Sodium Ion Batteries
摘要
Abstract
NaF-M (M=Fe, Cu) nanocomposites were prepared by high-energy ball milling using TiN grind- ing nanoparticles and investigated as cathode materials for sodium ion batteries. The experimental results dem-onstrated that NaF-Fe and NaF-Cu nanocomposites can go through electrochemical conversion reaction with Na ^+ uptake or removal, delivering a reversible capacity of- 150 mAh·g^-1, even through a reversed conver-sion from initial discharged state to a charged state. These results reveal the possibility to realize a conversion reaction as long as NaF and elemental metal particles are intimately contacted to form active nanocomposites at nanodomain, which suggests a potential feasibility to use these nanocomposites as sodium-rich cathode materi-als for sodium ion batteries.关键词
