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.

Secondary battery

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.

Electric cells

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.

Electric cells and process for making the same

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.
