  • Patent number: 10263277
    Abstract: Exemplary flexible thin film solid state lithium ion batteries (10) and methods for making the same are disclosed. An exemplary flexible solid state thin film electrochemical device (10) may include a flexible substrate (12), first (14) and second electrodes (18), and an electrolyte (16) disposed between the first (14) and second electrodes (18). The electrolyte (16) is disposed on the flexible substrate (12). The first electrode (14) is disposed on the electrolyte (16), and the second electrode (18) having been buried between the electrolyte (16) and the substrate (12).

  • Patent number: 9093707
    Abstract: A lithium metal thin-film battery composite structure is provided that includes a combination of a thin, stable, solid electrolyte layer [18] such as Lipon, designed in use to be in contact with a lithium metal anode layer; and a rapid-deposit solid electrolyte layer [16] such as LiAlF4 in contact with the thin, stable, solid electrolyte layer [18]. Batteries made up of or containing these structures are more efficient to produce than other lithium metal batteries that use only a single solid electrolyte. They are also more resistant to stress and strain than batteries made using layers of only the stable, solid electrolyte materials. Furthermore, lithium anode batteries as disclosed herein are useful as rechargeable batteries.

  • Publication number: 20100143769
    Abstract: Provided herein are methods for manufacturing lithium-metal anode [18] assemblies for thin-film, thick-film and hulk secondary batteries that use liquid or gel-type electrolytes [14], and lithium-metal anode [18] assemblies for thick-film and bulk secondary batteries that use solid electrolytes [18]. These methods involve electrolytic formation of a lithium metal anode [18] between a protecting lithium-stable, solid electrolyte [18] material and an eieethcaiiy-Gonductive substance [20]. Secondary lithium_ batteries made by these methods aw also provided.

  • Patent number: 6077401
    Abstract: A method of producing soot containing high amounts of fullerenes comprising: providing a primary concentrator capable of impingement of a concentrated beam of sunlight onto a carbon source to cause vaporization of carbon and subsequent formation of fullerenes, or providing a solar furnace having a primary concentrator with a focal point that concentrates a solar beam of sunlight; providing a reflective secondary concentrator having an entrance aperture and an exit aperture at the focal point of the solar furnace; providing a carbon source at the exit aperture of the secondary concentrator; supplying an inert gas over the carbon source to keep the secondary concentrator free from vaporized carbon; and impinging a concentrated beam of sunlight from the secondary concentrator on the carbon source to vaporize the carbon source into a soot containing high amounts of fullerenes.
