NON-AQUEOUS ELECTROLYTE CELL AND PRODUCTION METHOD THEREOF

PURPOSE: An electrolyte cell is to improve capacitance of the cell within a determined dimension of exterior material of the cell and to cause a simple production and secure accuracy of positioning of exterior terminal. CONSTITUTION: A unit cell(1) is provided on an encapsulating medium(2) of laminated films. Edge of the resultant assembly is heat fused for airtight sealing. The unit cell comprises a negative terminal lead(3) and a positive terminal lead(4) connected to a negative pole and a positive pole of the unit cell. The negative terminal lead and the positive terminal lead are drawn out of the encapsulating medium. A method for producing a non aqueous electrolyte cell comprises a step of detecting a position of a pole terminal lead and a step of determining a position of the lead with regard to a flat winding axis. Active material is formed on an electric collection device to which electrode terminal lead is attached to form a positive pole.
