  • Synthesis of gamma monoclinic sulfur and sulfur batteries containing monoclinic sulfur
    Patent number: 10991944
    Abstract: The present invention relates to a method for making a novel cathode employing a monoclinic sulfur phase that enables a single plateau lithium-sulfur reaction in, for example, a carbonate electrolyte system. The cathode is applicable to a variety of other types of anodes. The method produces a cathode suitable for use in an electrode of a cell or battery by depositing monoclinic phase sulfur via vapor deposition onto a substrate in a sealed vapor deposition apparatus.
