1. WOWO/2014/125331 - ALL-VANADIUM REDOX FLOW BATTERY SYSTEM EMPLOYING A V+4/V+5 REDOX COUPLE AND AN ANCILLARY Ce+3/Ce+4 REDOX COUPLE IN THE POSITIVE ELECTROLYTE SOLUTION21.08.2014
H01M 8/18
PCT/IB2013/051199HYDRAREDOX TECHNOLOGIES INC.SPAZIANTE, Placido, Maria
An ancillary Ce+3/Ce+4 redox couple is added to the positive electrolyte solution containing the V+4/V+5 redox couple of an RFB energy storage system in a mole content sufficient to support charge current in case of localized depletion of oxidable V+4V ions in the anode double layer on a wetted carbon electrode surface at a polarization voltage approaching 1.5 V, thus restraining any further increase that would lead to massive OH- discharge on the carbon electrode. Such a "buffering" function of the fraction of oxidable of C+3 ions, substitutes of no longer present oxidable V+4 ions, may eventually continue after a substantially complete oxidation to V+5 of the vanadium of the main redox couple V+4/V+5 in the positive electrolyte solution and to this end a balancing mole amount of a reducible redox couple is also added to the negative electrolyte solution. Of course, the added fractions (concentrations) of ancillary redox couple element or elements in the two electrolyte solutions will be determined in function of the minimum time interval after full oxidation of the vanadium load the system may remain operating before stopping an inadvertent run out charging process (maximum tolerable overcharge).

3. WOWO/2014/125662 - HIGH-CONCENTRATION VANADIUM ELECTROLYTE, AND METHOD AND APPARATUS FOR PRODUCING SAME21.08.2014
H01M 8/18
PCT/JP2013/067340GALAXY CO., LTD.UTSUMI, Kenichi
The present invention addresses the problem of providing a high-concentration vanadium electrolyte that contains a high-concentration of vanadium ions that could not hitherto be prepared, that is used in circulating-type redox flow batteries or non-circulating-type redox non-flow batteries, and that is not prone to generating sludge; and a method and an apparatus for producing the high-concentration vanadium electrolyte. The abovementioned problem is solved by a high-concentration vanadium electrolyte which is a sulfuric acid solution containing vanadium ions within a range of over 1.7 mol/L to 3.5 mol/L. The vanadium electrolyte is prepared by: preparing a first solution obtained by mixing vanadium salt with fresh water to dissolve the vanadium salt, preparing a second solution by adding sulfuric acid to the first solution while conducting pre-electrolysis of the first solution, and using the second solution itself, or by adding, to the second solution, fresh water or fresh sulfuric acid for adjusting the second solution to a final total amount.

4. WOWO/2014/126996 - GRAPHENE-BASED PROTON EXCHANGE MEMBRANE FOR DIRECT METHANOL FUEL CELLS21.08.2014
H01M 8/10
PCT/US2014/016019UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.MOGHADDAM, Saeed
A proton exchange membrane (PEM) for use in a direct methanol fuel cell (DMFC) is a laminate of graphene oxide (GO) or sulfonated graphene oxide (SGO) platelets. The mean size of the platelets is at least 10 μmι in diameter and the platelets are combined as a laminate. By use of sufficiently large platelets, the stability of the PEM and the resistance to methanol permeation is improved dramatically with little penalty to the proton conductivity of the GO or SGO PEM. The methanol resistant PEM permits the use of higher methanol concentrations at the anode of a DMFC, for high cell performance.

10. WOWO/2014/127272 - A POLAR SOLVENT ELECTRICAL ENERGY STORAGE DEVICE21.08.2014
H01M 6/52
PCT/US2014/016553FELTON, Samuel P.FELTON, Samuel P.
A novel electrical energy storage system that includes one or more cells. Each cell includes a polar liquid, a negatively-charged-surface electrode, and a positively-charged surface electrode. An interstitial space is defined between the electrodes. The negatively-charged-surface electrode has a hydrophilic surface adjacent the interstitial space. The liquid includes a self-organizing zone in the interstitial space. Each cell includes means to increase and/or decrease electrical potential between the electrodes. Increasing the electrical potential between the electrodes induces expansion of the self-organizing zone in the interstitial space. Decreasing electrical potential between the electrodes (e.g., via current discharge through an external load) causes a contraction of the self-organizing zone.
