C22C 3200
US Classification:
419 18, 423440, 75240, 419 17
Abstract:
A method for the synthesis of method for the manufacture of carbide cermet powders, comprises high energy ball milling a mixture of precursor powders and a carbon source, followed by annealing the milled powder mixture. The precursor powders are selected from materials suitable for the formation of cermets, for example silicon, titanium, thorium, hafnium, vanadium, chromium, tungsten, tantalum, niobium, and zirconium-containing materials. The precursors further include a source of carbon.

Inventors:
Wei Wang - Kennewick WA,
Liyu Li - Richland WA,
Zhenguo Yang - Richland WA,
Zimin Nie - Richland WA,
Assignee:

International Classification:
H01M 8/18
H01M 8/20
US Classification:
429107
Abstract:
Iron-sulfide redox flow battery (RFB) systems can be advantageous for energy storage, particularly when the electrolytes have pH values greater than 6. Such systems can exhibit excellent energy conversion efficicency and stability and can utilize low-cost materials that are relatively safer and more environmentally friendly. One example of an iron-sulfide RFB is characterized by a positive electrolyte that comprises Fe(III) and/or Fe(II) in a positive electrolyte supporting solution, a negative electrolyte that comprises S and/or S in a negative electrolyte supporting solution, and a membrane, or a separator, that separates the positive electrolyte and electrode from the negative electrolyte and electrode.

Hybrid Energy Storage Systems Utilizing Redox Active Organic Compounds

View page
US Patent:
2013026, Oct 10, 2013
Filed:
Apr 4, 2012
Appl. No.:
13/439083
Inventors:
Wei Wang - Kennewick WA,
Wu Xu - Richland WA,
Liyu Li - Richland WA,
Zhenguo Yang - Richland WA,
Assignee:
BATTELLE MEMORIAL INSTITUTE - Richland WA
International Classification:
H01M 10/05
H01M 4/13
H01M 10/02
H01M 4/64
US Classification:
429105, 429211, 429307, 429188
Abstract:
Redox flow batteries (RFB) have attracted considerable interest due to their ability to store large amounts of power and energy. Non-aqueous energy storage systems that utilize at least some aspects of RFB systems are attractive because they can offer an expansion of the operating potential window, which can improve on the system energy and power densities. One example of such systems has a separator separating first and second electrodes. The first electrode includes a first current collector and volume containing a first active material. The second electrode includes a second current collector and volume containing a second active material. During operation, the first source provides a flow of first active material to the first volume. The first active material includes a redox active organic compound dissolved in a non-aqueous, liquid electrolyte and the second active material includes a redox active metal.
