Abstract:
An electrolyte system (40) for use in connection with an electrochemical cell (10). The cell (10) includes a positive (20) and a negative (30) electrode and the electrolyte system (40) disposed therebetween. The electrolyte system includes a liquid electrolyte adapted to provide ion transport between the positive and negative electrodes and a segmented block copolymeric support structure for engaging the liquid electrolyte.

Abstract:
An electrochemical cell (10) includes first and second electrodes (12) and (14) with an electrolyte system (26) disposed therebetween. The electrolyte system includes at least a first and second layer (28) and (30), the second layer (30) being gelled and used to absorb an electrolyte active species.
Abstract:
An electrochemical cell (10) includes first and second electrodes (12 and 14) with an electrolyte system (26) disposed therebetween. The electrolyte system includes at least a filler material and a gelling polymer. The filler material comprises at least about 50 vol. % of the total amount of polymer in the electrolyte system, and has a porosity on the order of about 20-80 %.
Abstract:
A secondary lithium electrochemical charge storage device, such as a battery (10) is taught. The battery (10) includes a first composite electrode (20), and electrolyte layer (40), and a second composite electrode (30). The composite electrodes include at least an active material, and a polymer or polymer blend for lending ionic conductivity and mechanical strength. The electrolyte may also include a polymer as well as an electrolyte active material. The polymer from which the composite electrode is fabricated may be the same as or different than the polymer from which the electrolyte layer is fabricated.
