Fluorine-donating electrolytes enable highly reversible 5-V-class Li metal batteries

Significance Rechargeable lithium metal battery (RLMB) is the holy grail of high-energy-density batteries. If lithium metal anode (LMA) could be combined with 5-V LiNi 0.5 Mn 1.5 O 4 cathode, energy density could exceed 600 Wh/kg based on the cathode and anode electrode mass. Despite such promises, ...
