<p><P>PROBLEM TO BE SOLVED: To provide an nonaqueous electrolyte solution battery equipped with an electrode plate which is formed by molding a positive electrode mixture layer containing a principal composition of fluorocarbon held on a metal core material, an anode composed of lithium metal or its alloy, and an electrode plate group which is wound spirally, and provide a highly reliable battery in which a deviation in constructing the electrode plate group in a width-wise direction and an inner short circuit are prevented even in case a circumferential edge of the cathode plate faces the anode plate because of meandering of the electrode plate. <P>SOLUTION: In the nonaqueous electrolyte solution battery composed of a cathode containing fluorocarbon and an anode containing lithium metal or a lithium alloy, a width of a cathode plate made by molding in a sheet shape a cathode active substance containing fluorocarbon filled in or coated on a metal core material is larger than that of the anode plate made by cutting a foil of the lithium metal or the lithium alloy in a predetermined size, and a width of the core material of the cathode plate is smaller than that of the cathode plate, with a compounding ratio of a binding agent contained in the cathode electrode of 13 or more in weight to fluorocarbon as 100. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
