Stable electrode/electrolyte interfaces regulated by dual-salt and localized high-concentration strategies for high-voltage lithium metal batteries

High-voltage lithium metal batteries (LMBs) have faced application obstacles derived from the unstable interfacial layers on both the cathode and anode sides. Herein, a dual-salt localized high-concentration electrolyte (LHCE) is optimized to modify the anion-derived inorganic-rich interfacial layers with conductive inorganic and robust organic components. Dual-salt LHCE creates robust and inorganic-rich interfacial layers on cathode and anode to stabilize high-voltage cathode and high-active Li-metal anode.

Automated summary

In this study, a dual-salt localized high-concentration electrolyte (LHCE) has been optimized to modify the unstable interfacial layers in high-voltage lithium metal batteries (LMBs). The modified interfacial layers on both cathode and anode sides stabilize the high-voltage cathode and high-active Li-metal anode.
