摘要： An enclosed lead storage battery includes an enclosed container, a group of electrode plates including positive electrode plates and negative electrode plates, and separators, with the group of electrode plates and the separators being housed in the container. The positive electrode plates, negative electrode plates, and separators are layered side by side, with each of the positive electrode plates and negative electrode plates including a top side, a bottom side, and opposite lateral sides. At least one of the positive electrode plates and at least one of the negative electrode plates provide a grid having no frames at opposite lateral sides of the grid, such as an expanded grid. To prevent a short-circuit between the positive and negative electrode plates, the battery includes a porous mat disposed between the container and the opposite lateral sides of the grid.

摘要： A lithium battery made with a bipolar polyimide membrane with metal layers on each side, including one embodiment where the polyimide has a gold layer on each side. Different formulations for the positive electrode active material are used. The positive electrode active materials are essentially three substances: first, a lithium compound selected from the group consisting of LiCoO2, LiNiO2, and LiMn2O4; second, a powder selected from the group consisting of AB (acetylene black powder) and graphite; and third, PVDF (polyvinyldifluoride). The negative electrode active material consists essentially of two substances: the first is graphite powder; the second is PVDF (polyvinyldifluoride). The positive electrode metals include gold and aluminum. The negative electrode materials include gold, copper, nickel, titanium and iron. A separator layer of polyethylene is used so the battery layers can be wound. Because of the strength of the polyimide, the battery can be tightly wound. The energy density of the battery is about 300 Watt-hours per cubic centimeter.
