WIPO Patent Application WO/2019/198495

Kind Code:

A1

Abstract:

[Problem] To provide a battery production method capable of reducing the internal resistance of a battery by forming single cells when laminating single cells. [Solution] A battery production method comprising a lamination step in which a plurality of single cells 20 is laminated, each single cell being formed by laminating, with a separator therebetween, a current collector, a positive electrode formed by forming, on a positive current collector, a positive electrode active material layer containing an electrolyte solution, and a negative electrode formed by forming, on a negative current collector, a negative electrode active material layer containing an electrolyte solution. In the lamination step, each time a single cell is laminated, the laminated single cell is pressed from the laminating direction.
