  • Publication number: 20250149655
    Abstract: The disclosure herein relates to rechargeable batteries and solid electrolytes therefore which include lithium-stuffed garnet oxides, for example, in a thin film, pellet, or monolith format wherein the density of defects at a surface or surfaces of the solid electrolyte is less than the density of defects in the bulk. In certain disclosed embodiments, the solid-state anolyte, electrolyte, and catholyte thin films, separators, and monoliths consist essentially of an oxide that conducts Li+ ions. In some examples, the disclosure herein presents new and useful solid electrolytes for solid-state or partially solid-state batteries. In some examples, the disclosure presents new lithium-stuffed garnet solid electrolytes and rechargeable batteries which include these electrolytes as separators between a cathode and a lithium metal anode.

  • Patent number: 11127942
    Abstract: This disclosure provides systems and methods of manufacturing an anode, which can include nucleating a plurality of carbon particles at a first concentration level, forming a first film on a sacrificial substrate based on the first concentration level, each of the carbon particles defined by a plurality of aggregates formed of few layer graphene sheets fused together, defining a porous structure based on the few layer graphene sheets; and infusing a molten lithium (Li) metal into the porous structure. A plurality of interconnected porous channels can be defined based on the plurality of carbon particles. A second film can be formed by nucleating the carbon particles at a second concentration level on the first film. The first film can be configured to provide a first electrical conductivity and the second film can be configured to provide a second electrical conductivity different than the first electrical conductivity.

  • Patent number: 10077511
    Abstract: A plurality of elongate loom sections are interconnected via male and female connectors to form a modular hand loom having a size that is adjustable. A first loom section has a male connector extending from an end portion of the first loom section. A second loom section has a female connector configured to connect to the male connector in a snap fit arrangement. The second loom section includes a release member to facilitate disconnection of the male connector from the female connector.
