    摘要: Lithium anode based battery systems can use polymeric binding materials to act as particulate binders for fluorinated carbon based electrodes. The binders mechanically hold electrochemically active particles together, while inhibiting lithium fluoride crystallization that generates unwanted heat release in a discharging battery. Polymeric binders that include positively-charged groups, negatively-charged groups, electron deficient π-anion receptor groups, or boronate-based fluoride receptor group can be used alone or in combination.

    摘要: A novel and improved rechargeable, lithium-ion battery system is composed of a plurality of individual electrochemical cells having positive and negative electrodes disposed in opposite face-to-face arrangement with a porous separator containing electrolyte therebetween, and wherein the positive and negative electrodes of adjacent cells are disposed in contact respectively with opposite sides of a common current-collecting element forming a unitary bipolar structure. The negative electrode comprises a layer of carbon adhered to one side of the current-collecting element while the positive electrode comprises a layer containing a lithium transition metal oxide or sulfide compound adhered to the other opposite side of the element. The unitary bipolar structures containing the positive and negative electrodes of adjacent cells include outer peripheral, electrically-insulating seal members, preferably in the form of plastic insulating rings, which are joined together in a sealed stacked array.

    摘要: A getter electrode is provided to prevent dendrite formation and growth in electrochemical cells having alkali metal anodes such as lithium. The getter electrode includes a relatively thin, for example, about 2 mil thick layer of active material selected from the group consisting of carbon, graphite and mixtures thereof disposed on an inert substrate such as glass fiber separator paper. The getter electrode is positioned between the anode and the cathode in the cell and is separated from the anode and cathode by separators of fiberglass paper or the like. The getter electrode functions as a cathode with low rate capabilities. When dendrites arrive at the getter electrode from the anode or cathode, they are immediately discharged and not allowed to grow beyond the getter electrode. The result is a dramatic improvement in the cell cycle life and capacity retention.
