Abstract
A cell that is excellent in discharge characteristics and cycle characteristics is provided by filtering an active material paste, which contains an active material, a binder resin solution, and a conducting agent added as required, at least one time by a filter while stirring the active material paste in a stirring apparatus that has a stirring blade, and then coating a current collector with the active material paste. An active material paste is circulated and filtered by a feeding pump and a filter while being stirred in a stirring apparatus that has a stirring blade. Then, the active material paste is fed to another filter by a metering pump and filtered, and then, a current collector (backing) is coated with the active material paste. Then, the active material paste is dried in a dry zone and taken up by a take-up roller.
