ELECTROCHEMICAL CELL CONSISTING OF ALKALI METAL CELL INCLUDING DOUBLE COLLECTOR CATHODE STRUCTURE USING SAME ACTIVE MATERIAL OR ION ELECTROCHEMICAL CELL IN VARIETY OF MIXED BODIES

摘要

PROBLEM TO BE SOLVED: To provide an electrochemical cell which consists of an alkali metal cell including a double collector cathode structure using a same active material or an ion electrochemical cell in a variety of mixed bodies. SOLUTION: The electrochemical cell is equipped with an anode, a cathode which is so structured that a cathode active material including a first mixed body and a cathode active material including a second mixed body short circuit, each of the first and second mixed bodies consisting of a cathode active material and non-active material, and electrolyte solution to activate the anode and the cathode.
