  • Patent number: 11136647
    Abstract: A method for generating alkali metal in a zero oxidation state includes reacting an alkali metal compound having a —S-M substituent, where M is an alkali metal and S is sulfur, with gold in a zero oxidation state to release the alkali metal in the zero oxidation state. For example, an alkali metal alkylthiolate can be reacted with a gold in a zero oxidation state to release the alkali metal in the zero oxidation state. As another example, an alkali metal sulfide can be reacted with gold in a zero oxidation state to release the alkali metal in the zero oxidation state. The alkali metal may be used in various applications including vapor cells, magnetometers, and magnetic field measurement systems.

  • Patent number: 10811680
    Abstract: A battery comprises electrodes formed from the same metal oxide and an electrolyte solution comprising a source of cations which can be intercalated into the metal oxide. The battery can store electrical charge by connecting one of the electrodes to an external power source to reduce at least some of the metal atoms in the metal oxide forming the electrode from a higher to a lower oxidation state through the uptake of intercalating cations from the electrolyte and thereby create a potential difference between the electrodes, which electrical charge can be discharged by electrically connecting the electrodes. The electrodes are preferably formed from a multi-valent transition metal oxide, such as a tungsten, vanadium, cobalt or molybdenum oxide, more preferably tungsten trioxide. The intercalating cations are preferably protons and the electrolyte an acid.
