摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a lithium ion secondary battery in which active material density of an electrode is improved.

SOLUTION: A current collector 10 coated by an electrode slurry 11 before polymerization is placed in a pressure vessel 2, and while the pressure vessel 2 is pressurized by an inert gas from a gas cylinder 3, the interior of the pressure vessel is overheated by a heater 6, electrode slurry 11 before the polymerization is polymerized, and an electrode is formed.
