摘要: Primary and secondary Li-ion and lithium-metal based electrochemical cell systems. The suppression of gas generation is achieved through the addition of an additive or additives to the electrolyte system of respective cell, or to the cell itself whether it be a liquid, a solid- or plasticized polymer electrolyte system. The gas suppression additives are primarily based on unsaturated hydrocarbons.

摘要: 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.

摘要: Disclosed is a nonaqueous and nonvolatile liquid type polymeric electrolyte comprising poly(siloxane-g-ethylene oxide). This electrolyte provides significant safety and stability. The present invention solves the problems of volatility, flammability and chemical reactivity of lithium ion type electrolytes. The disclosed electrolyte exhibits excellent stability, conductivity and low impedance characteristics. The electrolyte comprises a new class of structural siloxane polymers with one or more poly(ethylene oxide) side chains. The inorganic siloxanes comprising the main backbone of the copolymers are thermally very stable and resistant to decomposition by heat. Because the main chain of the disclosed class of electrolytes is an Si—O linkage, initiation of the combustion cycle is inhibited or prevented.
