  • Publication number: 20230313362
    Abstract: Methods and articles of manufacture for free-standing lithium phosphorus oxynitride (LiPON) thin films are disclosed. The methods facilitate synthesizing the LiPON thin films in a free-standing form with controllable film thicknesses and areas. The free-standing LiPON thin films, absent a solid substrate contacting the LiPON thin films, enable studying fundamental properties of LiPON thin films including mechanical properties and glassy transition behavior. In some embodiments, the method includes modifying a surface of a substrate, forming a layer of LiPON on the modified surface of the substrate, and separating the layer of LiPON from the substrate. The free-standing LiPON thin films, no longer requiring solid substrates, may be used in applications requiring an ionically conductive or electronically insulating coating, film, or barrier layer.

  • Patent number: 11769908
    Abstract: Presented are new, earth-abundant lithium superionic conductors, Li3Y(PS4)2 and Li5PS4Cl2, that emerged from a comprehensive screening of the Li—P—S and Li-M-P—S chemical spaces. Both candidates are derived from the relatively unexplored quaternary silver thiophosphates. One key enabler of this discovery is the development of a first-of-its-kind high-throughput first principles screening approach that can exclude candidates unlikely to satisfy the stringent Li+ conductivity requirements using a minimum of computational resources. Both candidates are predicted to be synthesizable, and are electronically insulating. Systems and methods according to present principles enable new, all-solid-state rechargeable lithium-ion batteries.

  • Patent number: 11575116
    Abstract: A method of treating the surface of a positive electrode active material that is capable of inhibiting a reaction at the interface between a sulfide-based solid electrolyte and the positive electrode active material. A positive electrode active material particle for sulfide-based all-solid-state batteries, the surface of which is reformed, using the method and a sulfide-based all-solid-state battery, the charge/discharge characteristics of which are improved, including the same are also disclosed. The positive electrode active material particle for sulfide-based all-solid-state batteries manufactured using a dry-type method exhibits larger capacity than a positive electrode active material particle for sulfide-based all-solid-state batteries manufactured through a conventional wet-type process. In addition, the manufacturing process is simplified, and the amount of byproducts is reduced.

  • Publication number: 20230014961
    Abstract: In a method for recycling all solid-state batteries, spent battery cells are dissolved in anhydrous ethanol. The resulting solution is separated into solids and supernatants which are separately processed to regenerate the solid electrolyte and the solid electrode materials. The supernatant is subjected to vacuum evaporation to precipitate an electrolyte powder, which is then annealed under flowing oxygen. The solid electrode material is regenerated by washing the solids with water, drying the washed solids, relithiating the washed solids, and annealing the relithiated solids. The resulting materials are suitable for use in fabrication of new all-solid state batteries.
