  • Method of producing iron phosphide, positive electrode for lithium secondary battery comprising iron phosphide, and lithium secondary battery comprising same
    Patent number: 11349113
    Abstract: A method for preparing iron phosphide (FeP), a positive electrode of a lithium secondary battery including iron phosphide (FeP), for instance, prepared using the method, and a lithium secondary battery including the same. In the lithium secondary battery including the positive electrode using iron phosphide (FeP), the iron phosphide (FeP) adsorbs lithium polysulfide (LiPS) produced during a charge and discharge process of the lithium secondary battery, which is effective in increasing charge and discharge efficiency and enhancing lifetime properties of the battery.
    Type: Grant

  • Positive electrode for lithium-sulfur battery comprising maghemite and lithium-sulfur battery comprising the same
    Patent number: 11302907
    Abstract: A positive electrode of a lithium-sulfur battery including maghemite as an additive and a lithium-sulfur battery including the same. The maghemite obtained by heat treatment of lepidocrocite adsorbs lithium polysulfide (LiPS) generated from a lithium-sulfur battery, thereby improving the charging/discharging efficiency and capacity of the battery, as well as increasing the life of the battery.

  • Method for preparing iron oxide-hydroxide (FeOOH) and positive electrode for lithium-sulfur battery comprising iron oxide-hydroxide
    Patent number: 11038174
    Abstract: A method for preparing Iron Oxide-hydroxide (FeOOH), and a positive electrode for a lithium-sulfur battery including Iron Oxide-hydroxide. In particular, the preparation of crystalline Iron Oxide-hydroxide, particularly, lepidocrocite (?-FeOOH), by controlling a reaction time and a reaction temperature, and by using the prepared high purity Iron Oxide-hydroxide in a positive electrode of a lithium-sulfur battery, may enhance discharge capacity and lifetime properties of the battery.
