Abstract:
A novel lithium salt (lithium di-fluoro di-nonafluoro-tert-butoxy borate) shows high solubility (>1 M) and flame-retardant properties in an electrolyte solution with conventional carbonate solvents as well as stable cycling in a high-voltage (4.8 V) LiNi0.5Mn1.5O4-graphite based lithium-ion battery.
