A thin conformal Li-ion permeable oxide layer is created by rapid plasma enhanced atomic layer deposition (PEALD) for lithium–sulfur batteries in order to prevent the polysulfide dissolution. PEALD offers a fast deposition rate combined with a low operating temperature, which avoids sulfur evaporation during deposition. The result is significantly enhanced cycle life with a capacity of up to 600 mA·h·g−1.
