The reactions among lithium metal anode, cathode, and electrolyte contribute to the origin of thermal runaway of Li metal batteries (LMBs). In this contribution, polyethylene glycol (PEG) is adopted as an effective thermal safety modifier to reduce the reactions between cell components. The heat rel...
