    Abstract: In accordance with the non-aqueous electrolyte secondary battery of the invention and the process for the preparation thereof, charging is carried out with a combination of a positive electrode provided with excess lithium and a negative electrode in order to cause lithium to be deposited on the negative electrode. Accordingly, no oxidized surface film is interposed between lithium and the current collector of negative electrode or the negative active material layer as in the case where a metallic lithium foil is laminated on the negative electrode. In this arrangement, a battery having a small internal resistance can be provided. Since the deposition of lithium is conducted in the assembled battery, lithium does not come in contact with air, preventing the formation of a thick ununiform oxidized film on the surface thereof. Thus, the deposition of dendrite can be inhibited, making it possible to inhibit the drop of battery capacity and hence provide a battery having an excellent cycle life performance. Further, lithium can be retained on the negative electrode in an amount excess to the capacity of the positive electrode. Accordingly, even when lithium is lost due to the deposition of dendrite or the reaction with the electrolyte solution, the drop of battery capacity can be inhibited because the negative electrode is provided with excess lithium.

    Abstract translation: 根据本发明的非水电解质二次电池及其制备方法,通过组合具有过量的锂和负极的正极来进行充电,以使锂沉积在 负极。 因此,在金属锂箔层叠在负极上的情况下,在锂和负极的集电体或负极活性物质层之间没有氧化的表面膜。 在这种布置中,可以提供具有小内阻的电池。 由于在组电池中进行锂的沉积,所以锂不与空气接触,防止在其表面形成厚的不均匀的氧化膜。 因此,可以抑制枝晶的沉积,使得可以抑制电池容量的下降,从而提供具有优异的循环寿命性能的电池。 此外,锂可以以超过正极的容量的量保持在负极上。 因此,即使锂由于枝晶的沉积或与电解质溶液的反应而损失,由于负极具有过量的锂,所以可以抑制电池容量的下降。

    Abstract: An electrochemical capacitor includes a polymer thin film, a liquid electrolyte absorbed in the polymer thin film, and thin flexible active electrode layers constituting anode and cathode composed of energy dense material of high intrinsic surface area positioned at either side of the electrolyte-retaining polymer thin film to tightly sandwich it between the electrode layers. In one embodiment, the capacitor includes a polymer electrolyte in which a polymer thin film is cast from the base polymer and impregnated with the electrolyte solution, which contains a salt for ionic conduction. In another embodiment, the base polymer material includes an ionically conducting polymer, a perfluorocarbon polymer backbone to which sulfonic acid sites are permanently anchored. The energy dense material of the electrode layers may be physically mixed with battery active material to enhance the capacity and discharge time of the capacitor. In fabrication, the electrode material is reduced to particle size suitable for application to a thin film metallized polymer substrate, and applied directly and adherently on opposite sides of the substrate by injection, spraying, or evaporation, and a final thin flexible film of each electrode is formed with a desired thickness by use of rods if a slurry, or by controlling the extent of spray or evaporation, followed by curing. In another embodiment, the electrode elements are laminated directly onto opposite sides of a single- or double-metallized polymer substrate.
