Discovering new solid electrolytes (SEs) is essential
to achieving
higher safety and better energy density for all-solid-state lithium
batteries. In this work, we report machine learning (ML)-assisted
high-throughput virtual screening (HTVS) results to identify new SE
materials. This approach expands the chemical space to explore by
substituting elements of prototype structures and accelerates an evaluation
of properties by applying various ML models. The screening results
in a few candidate materials, which are validated by density functional
theory calculations and ab initio molecular dynamics simulations.
The shortlisted oxysulfide materials satisfy key properties to be
successful SEs. The advanced screening method presented in this work
will accelerate the discovery of energy materials for related applications.
