Abstract: The invention relates to a method for depositing an electrical insulation layer on an electrochemical cell including a lower wall, a side wall and an upper wall on which a positive terminal and a negative terminal are arranged, the side wall and the upper wall being connected by a peripheral edge. The deposition method includes a step of depositing an electrical insulation layer during which the electrical insulation layer is deposited on the lower wall, the side wall, and only on one border of the upper wall the border extending from the peripheral edge toward the interior of the upper wall over a distance d, so as to form an electrical insulation strip covering the border and surrounding a central zone of the upper wall.
