A bipolar battery having at least two electrochemical cells stacked one on top of the other, the bipolar collector including, at the periphery of same, on one of the faces of same, at least one first sealing device including one frame made from an electrically insulating and thermosensitive material, and two adhesive frames arranged individually to either side of the thermosensitive frame, the first or the second adjacent collector also including, at the periphery of same, on the covered face of same, at least one second sealing device including a frame made from an electrically insulating and thermosensitive material, and two adhesive frames arranged individually to either side of the thermosensitive frame, the first and second devices each forming a peripheral wall sealed to the electrolyte of the first or second cell, which surrounds same. Each sealed wall is obtained by heat-sealing at least one first and at least one second sealing device on the face of a current collector not provided with a sealing device.
