Concurrent electrode–electrolyte interfaces engineering via nano-Si3N4 additive for high-rate, high-voltage lithium metal batteries

The nano-Si 3 N 4 additive enables the concurrent engineering of electrode–electrolyte interfaces. It promotes the formation of a bilayer, inorganic-rich SEI via its involvement in SEI formation and Li + solvation, and a uniform CEI by scavenging HF.
