STRIP ELECTRODE AND BATTERY USING IT

摘要

PROBLEM TO BE SOLVED: To solve such a problem that when an uncoated part continuing in the length direction is installed at the end part in the width direction, an electrode is easily deformed in a strip electrode having an active material layer on a current collector.

SOLUTION: The uncoated part along the length direction is installed even in a part other than the end part in the width direction in addition to the uncoated part at the end part in the width direction along the length direction in the strip electrode. Applying to the strip electrode in which width of the uncoated part at the end part is 5 mm or more or to the strip electrode in which linear pressure in roll press of the active material layer is 250 kg/cm or more is effective.
