The BN-carbon separator was first demonstrated as a multifunctional trilayer membrane to facilitate the better electrochemical performances of Li-S batteries and protect a Li anode from unexpected side reactions. Unlike the previous approach to block the polysulfides only within the cathodic side, the concept of placing a BN interlayer on anodic side showed promising results in achieving high electrochemical performances of Li-S batteries and stable operations of lithium metal at a high current density.
