  "textContent": "Disclosed herein are porous separators having a surface energy of at least 50 dynes/cm, which separators can be prepared by radiating oxygen plasma on a microporous polymer film. The oxygen plasma treatment yields significant reduction in electrolyte contact angle and wetting time of said separators when they are in contact with an electrolyte with high salt concentration. As a result, the oxygen plasma treatment improves the wetting by the electrolyte with high salt concentration and enables its use for high capacity and long cycle life rechargeable lithium metal batteries, which are also described herein.",
