Abstract
RuO2 particles on LiNi0.5Mn1.5O4 sustainably consume F radicals leading to the formation of a stable SEI layer. This is the reason for improvement of the cycle performance by the surface modification with discrete RuO2 particles in combination with setting discharge cut-off potentials to 4.5 V.
