Abstract
A type of stacked lithium ion secondary battery is disclosed. Therein, the positive electrode is formed by smearing an active material on the surface of an aluminum foil body, where said active material includes lithium with attachable and detachable lithium ions and compound oxide(s) of transition metals; and a strip extending from said aluminum foil body is used as the conductor of the positive electrode. The negative electrode is formed by smearing an active material on the surface of a copper foil body, where said active material includes carbon material capable of attaching and detaching lithium ions; and a strip extending from said copper foil body is used as the conductor of the negative electrode. The positive and negative electrodes in plate form are arranged and stacked on the two sides of the separator forming said electrode core. The stacked lithium ion secondary battery can effectively use the internal space of the battery shell, increasing the capacity density and decreasing the battery's internal resistance; thereby improving the large current discharge characteristic of the lithium ion secondary battery.
