Rational molecular design of electrolyte additive endows stable cycling performance of cobalt-free 5 V-class lithium metal batteries

Ultrahigh-voltage lithium metal batteries based on cobalt-free LiNi0.5Mn1.5O4 (LNMO) cathode (5 V-class, vs. Li+/Li) and lithium metal anode (-3.04 V vs. the standard hydrogen electrode) have attracted extensive attention in...
