摘要:
An electric cell comprising a positive electrode, a negative electrode, and an electrolyte maintains excellent performance when the positive electrode is an electro-conductive polymer composite including a mesh stainless steel having a wire diameter of about 35-120 .mu.m and an electro-conductive polymer, typically polyaniline, integrally deposited onto the mesh by electrolytic polymerization. A container having the elements received therein is provided with a vent mechanism.
摘要:
In an electrochemical cell comprising a positive electrode, a negative electrode, and an electrolyte, a film of electroconductive polymeric material having a conductor embedded therein at approximately the mid point of the film is used as an electrode active material and a collector associated therewith.
摘要:
A secondary battery comprising a positive electrode, a negative electrode, and an electrolyte is improved in discharge performance by forming the positive electrode from a composite electrode material including a conductive organic polymer and a dischargeable metal oxide and/or metal chalcogenide.
摘要:
An electric cell comprising a positive electrode, a negative electrode, and an electrolyte containing a lithium salt is provided wherein the negative electrode has a two-layer structure of a lithium-aluminum alloy layer and an aluminum layer. The cell is fabricated by placing a positive electrode, a negative electrode, and an electrolyte in a cell container comprising positive and negative electrode casings, and forming a seal between the positive and negative electrode casings. The negative electrode is electrochemically formed in situ in the cell container from a lithium-clad aluminum substrate.

Provided is an electric double-layer capacitor and the like, which may be easily manufactured. In a recessed container (2) constituting a package of an electric double-layer capacitor (1), a step portion (4) is formed. With this, the recessed container (2) has two parallel bottom surfaces which are not provided in the same plane, that is, a first bottom surface constituting a bottom portion of a recessed portion (13) and a second bottom surface constituting an upper surface of the step portion (4). The first bottom surface and the second bottom surface respectively have metallic layers (11, 9) formed thereon, which pass through the recessed container (2) toward an outside to respectively connect to terminals (12, 10). Electrodes (6, 5) are respectively connected to the upper surfaces of the metallic layers (11, 9).
摘要:
An electric double-layer capacitor is provided in which an upper end portion of a recessed container is sealed by a sealing plate. An electrode and an electrode are accommodated in a hollow portion formed by a recessed portion and the sealing plate. One step portion is formed in the middle of one inner peripheral surface of the recessed portion, and another step portion is formed in the middle of the other opposing inner peripheral surface. The one step portion and said another step portion are formed at the same height, and upper surfaces of those step portions exist on the same plane.
