摘要

LiMPO4 (M = Fe, Mn)是一种很有前途的锂离子电池正极材料。将固相反应合成的LiFe1-xMnxPO4 (x = 0、0.6、0.8和1)的7个锂离子位移与基于Li - o - m超转移超精细相互作用计算的7个锂离子位移范围进行比较。本文还对LiFe0.4Mn0.6PO4在不同截止电压下的首次充电过程进行了非原位7li NMR研究，以了解7li与LiFe0.4Mn0.6PO4的关系

Ex-situ 7 Li MAS NMR Study of Olivine Structured Material for Cathode of Lithium Ion Battery

Li nuclear magnetic resonance (NMR) spectra have been observed for LiMPO4 (M = Fe, Mn) samples, as a promising cathode material of lithium ion battery. Observed 7 Li shifts of LiFe1-xMnxPO4 (x = 0, 0.6, 0.8, and 1) synthesized with solid-state reaction are compared with calculated 7 Li shift ranges based on the supertranferred hyperfine interaction of Li–O–M. Ex situ 7 Li NMR study of LiFe0.4Mn0.6PO4 in different cut-off voltage for the first charge process is also performed to understand the relationship between 7 Li
