Multifunctional electrolyte additive for realizing high-temperature and high-voltage lithium metal batteries

Methyl 1H-1,2,4-triazole-3-carboxylate (MTC) was added into lithium metal batteries as an electrolyte additive, and not only did this addition lead to formation of solid electrolyte interfaces to protect both the anode and cathode, but the added MTC also served as a Lewis base in removing HF from the electrolyte to prevent the electrolyte from deteriorating. Therefore, the addition of MTC, in an appropriate amount, can be very effective at improving the electrochemical performance of lithium metal batteries.
