20090004565 | Silver manganese vanadium oxide electrodes for lithium batteries - This invention relates to electrodes for non-aqueous lithium cells and batteries. More specifically, the invention relates to silver manganese vanadium oxide positive electrodes for such cells and batteries. The silver manganese vanadium oxide electrodes may contain substituents or dopants to improve the electrochemical properties of the electrodes, cells and batteries. The silver manganese vanadium oxide electrodes optionally contain silver powder and/or silver foil to assist in current collection at the electrodes and to improve the power capability of the cells or batteries. The invention also includes a method for preparing the electrodes by decomposition of a permanganate salt, such as AgMnO | 01-01-2009 |
20100035153 | Multi-component intermetallic electrodes for lithium batteries - Multi-component intermetallic negative electrodes prepared by electrochemical deposition for non-aqueous lithium cells and batteries are disclosed. More specifically, the invention relates to composite intermetallic electrodes comprising two or more compounds containing metallic or metaloid_elements, at least one element of which can react with lithium to form binary, ternary, quaternary or higher order compounds, these compounds being in combination with one or more other metals that are essentially inactive toward lithium and act predominantly, but not necessarily exclusively, to the electronic conductivity of, and as current collection agent for, the electrode. The invention relates more specifically to negative electrode materials that provide an operating potential between 0.05 and 2.0 V vs. metallic lithium. | 02-11-2010 |
20100227220 | LITHIUM-OXYGEN (AIR) ELECTROCHEMICAL CELLS AND BATTERIES - This invention provides a lithium-oxygen or lithium-air electrochemical cell comprising a negative electrode, an electrolyte, and a porous activated positive electrode comprising lithium-rich electrocatalytic materials suitable for use in lithium-oxygen (air) cells and batteries. The activated positive electrode is produced by activating a precursor electrode formed from a material comprising one or more metal oxide compounds of general formula xLi | 09-09-2010 |

20130224538 | ORGANIC NON-AQUEOUS CATION-BASED REDOX FLOW BATTERIES - The present invention provides a non-aqueous redox flow battery comprising a negative electrode immersed in a non-aqueous liquid negative electrolyte, a positive electrode immersed in a non-aqueous liquid positive electrolyte, and a cation-permeable separator (e.g., a porous membrane, film, sheet, or panel) between the negative electrolyte from the positive electrolyte. During charging and discharging, the electrolytes are circulated over their respective electrodes. The electrolytes each comprise an electrolyte salt (e.g., a lithium or sodium salt), a transition-metal free redox reactant, and optionally an electrochemically stable organic solvent. Each redox reactant is selected from an organic compound comprising a conjugated unsaturated moiety, a boron cluster compound, and a combination thereof. The organic redox reactant of the positive electrolyte is selected to have a higher redox potential than the redox reactant of the negative electrolyte. | 08-29-2013 |
