NON-AQUEOUS ELECTROLYTIC SOLUTION BATTERY AND ITS MANUFACTURING METHOD

Japanese Patent JP3829086

B2

PROBLEM TO BE SOLVED: To provide a non-aqueous electrolytic solution battery and its manufacturing method provided with a constitution in which improvement of a battery capacity per unit volume can be aimed at without inviting deterioration of bond strength and a mechanical strength to a current collecting lead or a sealing plate or the like.
SOLUTION: This battery is provided with a battery case 8 of one of electrodes to house electrode groups 9 and an electrolytic solution, a sealing plate 17 in which an opening part of the battery case 8 is sealed and electrically connected, an electrode terminal 21 of the other electrodes arranged and installed at the sealing plate 17 in an insulated state, positive/negative electrode current collecting reeds 10, 11 in which respective one end part is respectively connected with respective core materials 30, 31 of the positive/negative electrodes 29, 29 of the electrode groups 9, and respective other end parts are respectively jointed to one side or the other side in the sealing plate 17 and the electrode terminal 21. The positive/negative electrode current collecting leads 10, 11 have connecting parts 12, 13 formed having a large thickness t2 on the other end part of the reed piece parts 15, 16 having a thin walled strip shape.
