    Abstract: The loss of sulfur cathode material as a result of polysulfide dissolution causes significant capacity fading in rechargeable lithium/sulfur cells. Embodiments of the invention use a chemical approach to immobilize sulfur and lithium polysulfides via the reactive functional groups on graphene oxide. This approach obtains a uniform and thin (˜tens of nanometers) sulfur coating on graphene oxide sheets by a chemical reaction-deposition strategy and a subsequent low temperature thermal treatment process. Strong interaction between graphene oxide and sulfur or polysulfides demonstrate lithium/sulfur cells with a high reversible capacity of 950-1400 mAh g?1, and stable cycling for more than 50 deep cycles at 0.1 C.

    Abstract: A magnesium ion-containing electrolyte used for a magnesium cell includes magnesium, halogen, one of boron, aluminum, and phosphorous, and an organic group including OCXHY. The magnesium ion-containing electrolyte has low reactivity with oxygen. Even when oxygen exists in the magnesium ion-containing electrolyte, a deterioration of the magnesium-ion containing electrolyte is restricted, and magnesium ions stably move.

  • Patent number: 8951676
    Abstract: An electrolyte for use in electrochemical cells is provided. The properties of the electrolyte include high conductivity, high Coulombic efficiency, and an electrochemical window that can exceed 3.5 V vs. Mg/Mg+2. The use of the electrolyte promotes the electrochemical deposition and dissolution of Mg without the use of any Grignard reagents, other organometallic materials, tetraphenyl borate, or tetrachloroaluminate derived anions. Other Mg-containing electrolyte systems that are expected to be suitable for use in secondary batteries are also described.
