► MTFMP is a new co-solvent for PC-based electrolytes with LiPF6 as lithium salt. ► MTFMP is able to suppress graphite exfoliation in PC-based electrolytes. ► MTFMP does not affect conductivity and increases the oxidative stability. ► Capacity retention of graphite-based cells is 99% after 300 cycle...
