摘要： Supercapacitor cell electrode and separator elements formulated as membranes of plasticized polymeric matrix compositions are laminated with electrically conductive current collector elements to form flexible, unitary supercapacitor structures.

摘要： The extent of self-discharge of rechargeable Li-ion secondary batteries is significantly reduced by treatment of LiMn.sub.2 O.sub.4 intercalation compound electrode material with a chelating agent, such as acetylacetone. This treatment decreases the incidence of non-coordinated Mn-ion sites which can lead to battery electrolyte decomposition and resulting loss of battery capacity. The treatment, which also includes annealing at about 400.degree. C. to 800.degree. C., further prevents such decomposition by varying the surface area and topography of the potentially catalytic electrode material.

摘要： Li-ion rechargeable battery cell electrode and electrolyte/separator elements formulated as layers of plasticized polymeric matrix compositions are laminated to form a unitary battery cell structure. The structure may be stored indefinitely, since it is essentially devoid of electrolyte solution which typically comprises a moisture-sensitive lithium salt. Prior to the battery's being put into service, the plasticizer of the polymeric composition is removed by leaching with a selective solvent and is replaced with a lithium salt electrolyte solution by simple imbibition. The battery thus activated may then be charged and recharged in the usual manner.
