Patent number: 11845765Abstract: A method for synthesizing a purified lithium (Li)+ anion binding agent (ABA-F)? salt and the corresponding Li+(ABA-F)? are disclosed. The method includes dissolving a boron-based acid in a polar solvent to form a solution. The solution is refluxed to form an anion binding agent. A stoichiometric amount of a small fluorinated salt, such as LiF, is added to the anion binding agent to form a mixture. The mixture is subsequently crystallized to obtain a substantially pure Li+(ABA-F)? salt. Example purified Li+(ABA-F)? salts include Ox-Li+(ABA-F), m-Li+(ABA-F), and BF3—Li+(ABA-F)?. These purified Li+(ABA-F)? salts provide the benefits of increased battery thermal safety without loss of electrochemical performance.Type: GrantFiled: October 27, 2020Date of Patent: December 19, 2023Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Christopher Orendorff, Ganesan Nagasubramanian, Kyle R.

Patent number: 10586997Abstract: A redox flow battery is described herein that has a sodium-super-ionic-conductor NaSICON barrier disposed between an anolyte chamber of the battery and the catholyte chamber of the battery. The NaSICON barrier prevents crossover of solvents or active redox species between the anolyte chamber and the catholyte chamber, while permitting transport of sodium ions between the chambers. In exemplary embodiments, the anolyte chamber includes an anolyte solution that comprises a first active redox species dissolved in a first solvent, while the catholyte chamber includes a catholyte solution that comprises a second active redox species dissolved in a second solvent.Type: GrantFiled: September 20, 2017Date of Patent: March 10, 2020Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: David Ingersoll, Ganesan Nagasubramanian, Eric Allcorn

Publication number: 20180053959Abstract: The fundamental charge storage mechanisms in a number of currently studied high energy redox couples are based on intercalation, conversion, or displacement reactions. With exception to certain metal-air chemistries, most often the active redox materials are stored physically in the electrochemical cell stack thereby lowering the practical gravimetric and volumetric energy density as a tradeoff to achieve reasonable power density. In a general embodiment, a mediated redox flow battery includes a series of secondary organic molecules that form highly reduced anionic radicals as reaction mediator pairs for the reduction and oxidation of primary high capacity redox species ex situ from the electrochemical cell stack. Arenes are reduced to stable anionic radicals that in turn reduce a primary anode to the charged state. The primary anode is then discharged using a second lower potential (more positive) arene. Compatible separators and solvents are also disclosed herein.Type: ApplicationFiled: September 13, 2017Publication date: February 22, 2018Inventors: Frank M. Delnick, David Ingersoll, Chengdu Liang

Publication number: 20130098212Abstract: A telescopic extension device for a handle of a wrench includes three sliding overlapping concentric tubular members. A mechanism is for retaining the three tubular members in an extended position. When the three tubular members are in the extended position, the handle of the wrench will snugly fit into a front end of the first tubular member having the smallest diameter, so as to help increase the amount of torque applied by a person using the wrench to either loosen and tighten a nut and bolt.Type: ApplicationFiled: October 24, 2011Publication date: April 25, 2013Inventors: David INGERSOLL, Rusty Vanas

Patent number: 7556945Abstract: Disclosed is an apparatus and method for continuously converting sucrose to ?-D-glucose. The method comprises a three-stage enzymatic reactor in which an aqueous solution of sucrose is first converted into a solution of fructose and ?-D-glucose by passing it through a porous, packed column containing an inert media on which invertase is immobilized. This solution is then sent through a second packed column containing glucose isomerase and finally a third packed column containing mutarotase. Solution temperature and pH are adjusted to maximize glucose output.Type: GrantFiled: July 5, 2007Date of Patent: July 7, 2009Assignee: Sandia CorporationInventors: Blake A. Simmons, Joanne V.

Patent number: 6086957Abstract: A method of preparing metal oxide thin films by a solution method. A .beta.-metal .beta.-diketonate or carboxylate compound, where the metal is selected from groups 8, 9, 10, 11, and 12 of the Periodic Table, is solubilized in a strong Lewis base to form a homogeneous solution. This precursor solution forms within minutes and can be deposited on a substrate in a single layer or a multiple layers to form a metal oxide thin film. The substrate with the deposited thin film is heated to change the film from an amorphous phase to a ceramic metal oxide and cooled.Type: GrantFiled: May 28, 1999Date of Patent: July 11, 2000Assignee: Sandia CorporationInventors: Timothy J.

Patent number: 5882621Abstract: A method of producing carbon materials for use as electrodes in rechargeable batteries. Electrodes prepared from these carbon materials exhibit intercalation efficiencies of .apprxeq.80% for lithium, low irreversible loss of lithium, long cycle life, are capable of sustaining a high rates of discharge and are cheap and easy to manufacture. The method comprises a novel two-step stabilization process in which polymeric precursor materials are stabilized by first heating in an inert atmosphere and subsequently heating in air. During the stabilization process, the polymeric precursor material can be agitated to reduce particle fusion and promote mass transfer of oxygen and water vapor. The stabilized, polymeric precursor materials can then be converted to a synthetic carbon, suitable for fabricating electrodes for use in rechargeable batteries, by heating to a high temperature in a flowing inert atmosphere.Type: GrantFiled: May 9, 1997Date of Patent: March 16, 1999Assignee: Sandia CorporationInventors: Narayan Doddapaneni, James C.
