20090286157 | Surface modification agents for lithium batteries - An active material for an electrochemical device may have a surface modification agent that is a silane, organometallic compound, or a mixture of two or more of such compounds. Both negative and positive electrodes may be prepared from the surface modified active materials. The surface of an electrode may be modified by adding the surface modification agent to a non-aqueous electrolyte used in constructing a battery. An electrode or active material may be modified with a surface modification agent in either the gas phase or in solution. Slurries of the active agent may be prepared and the surface modification agent added, the slurry then be used to cast an electrode that is then dried. | 11-19-2009 |
20100040954 | ELECTROLYTE SALTS FOR NONAQUEOUS ELECTROLYTES - Metal complex salts may be used in lithium ion batteries. Such metal complex salts not only perform as an electrolyte salt in a lithium ion batteries with high solubility and conductivity, but also can act as redox shuttles that provide overcharge protection of individual cells in a battery pack and/or as electrolyte additives to provide other mechanisms to provide overcharge protection to lithium ion batteries. The metal complex salts have at least one aromatic ring. The aromatic moiety may be reversibly oxidized/reduced at a potential slightly higher than the working potential of the positive electrode in the lithium ion battery. The metal complex salts may also be known as overcharge protection salts. | 02-18-2010 |

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 |
