文摘
- •
A comprehensive set of tests on LNMO/G cells are performed.
- •
Affinity between LiODFB/LiBF4 electrolyte and LNMO electrode is presented.
- •
A large proportion of LiODFB improves the cyclability at elevated temperature.
- •
A small percentage of LiBF4 ameliorates the usability at low temperature.
- •
An optimum molar ratio of LiODFB/LiBF4 is obtained.
