Abstract

The electrochemical behavior of the multicomponent layered oxide LiNi0.8Mn0.15Co0.05O2 in an electrolyte containing lithium oxalate difluoroborate (LiF2BC2O4) as the background salt was studied for the first time. It was shown that the overall polarization resistance in this electrolyte is significantly lower than in a LiClO4-based electrolyte in the same solvent, leading to an increase in discharge capacity, especially at elevated current loads.
