Reversible Bifunctional Air Electrode Catalyst For Rechargeable Metal Air Battery And Regenerative Fuel Cell

View page
US Patent:
20200168915, May 28, 2020
Filed:
Nov 22, 2019
Appl. No.:
16/692921
Inventors:
- Knoxville TN, US
Thomas Zawodzinski - Knoxville TN, US
Shane Foister - Knoxville TN, US
International Classification:
H01M 4/90
H01M 12/06
H01M 12/02
H01M 4/88
H01M 4/86
H01M 4/92
H01M 12/08
Abstract:
An electrochemical cell includes an air electrode in flow communication with a storage tank containing an aqueous solution of hydrogen peroxide, a lithium electrode, a catalyst layer in contact with the air electrode or a gas diffusion layer associated with the air electrode, and a separator layer in contact with the lithium electrode and catalyst layer. The catalyst layer includes a catalyst for two electron reversible oxygen reduction. The catalyst comprises gold, and a cobalt coordination complex or polymer thereof. The cobalt coordination complex comprises a cobalt ion chelated by a tetradentate organic chelating ligand.

US Patent:
20160308220, Oct 20, 2016
Filed:
Nov 3, 2014
Appl. No.:
15/033349
Inventors:
- Knoxville TN, US
Thomas ZAWODZINSKI - Knoxville TN, US
Shane FOISTER - Knoxville TN, US
International Classification:
H01M 4/90
H01M 4/88
H01M 12/02
H01M 4/86
H01M 12/06
Abstract:
A catalyst is provided for the two electron reduction of oxygen. The catalyst can be reversible or near-reversible. The catalyst comprises a gold and a cobalt coordination complex, i.e., N,N′-bis(salicylidene)ethylene-diaminocobalt (II) (cobalt salen) or a derivative thereof. The cobalt coordination complex can be polymerized to form a film, for example, via electropolymerization, to cover a gold surface. Also provided are metal-air batteries, fuel cells, and air electrodes that comprise the catalyst, as well as methods of using the catalyst, for example, to reduce oxygen and/or produce hydrogen peroxide.

US Patent:
20150072261, Mar 12, 2015
Filed:
Nov 8, 2013
Appl. No.:
14/075390
Inventors:
Matthew Mench - Knoxville TN, US
Thomas Zawodzinski - Knoxville TN, US
International Classification:
H01M 8/18
H01M 8/20
US Classification:
429452, 429499
Abstract:
An electrochemical flow type battery may include at least one electrode and a separator. The electrode may include carbon fibers and/or carbon particles, and has an internal surface area density of at least 1 m/g. The separator may separate an anode side and a cathode side of the battery. A flat surface of the electrode directly contacts a surface of the separator.
