Efficient Screening

An efficient screening procedure for two-dimensional (2D) solid-electrolyte interphases (SEIs) is designed. In the concrete case, the two selected 2D SEIs (h-BN and α-BNyne) do stabilize the interface between the solid-state electrolyte Li10GeP2S12 and the lithium metal anode, blocking the electron transfer and maintaining the Li-ion flow.
