Understanding the electrolyte additive properties of lithium nonafluoro-tert-butoxide for its application in high-voltage LiNi0.5Mn1.5O4-graphite batteries

A fluorinated lithium alkoxide salt, lithium nonafluoro-tert-butoxide, demonstrates higher stability on aluminium at high potential and shows improvement in the cycling performance of LNMO-graphite batteries (4.8 V) as the electrolyte additive.
