Document Type and Number:
Japanese Patent JP6900924
Kind Code:
B2
Abstract:
To provide a method for producing a laminated electrode body capable of inhibiting both ends in a length direction of a positive electrode mixture layer from being peeled off from a surface of a positive electrode current collector foil in a roll press process.SOLUTION: Of a pair of rolls 110, 120 used in a roll press step, the first roll 110 that contacts a positive electrode mixture layer 33 is so configured that rigidity of a portion 113 in contact with both end portions 33b, 33c in a length direction BH of a positive electrode mixture layer 33 is lower than rigidity of the portion 115 in contact with an intermediate portion 33d located between both ends 33b, 33c among the positive electrode mix layers 33.SELECTED DRAWING: Figure 7
