摘要： The invention relates to the use of a liquid/solid reversible phase change electrolyte to prepare a bipolar lithium-ion battery. Said use is characterized in that said electrolyte contains at least one block copolymer containing at least one polymer segment A, soluble in said electrolyte, and at least one polymer segment B, having a temperature T for solubilization in said electrolyte. The polymer segments A and B are present in sufficient amounts to allow physical gelling of the electrolyte at a temperature greater than or equal to the temperature T.

摘要： 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.

摘要： The present invention relates to a bipolar battery with at least two electrochemical cells stacked one above the other, each collector comprising at its periphery at least one bead of an electrical insulating material also constituting a peripheral zone of the electrolyte-leaktight wall. According to the invention, each leaktight wall is constituted of at least one bead consisting of a honeycomb matrix, the matrix being covered, on each of its two main faces, with a layer or leaf made of heat-sealing and electrically insulating material, each layer or leaf being heat-sealed to one of the current collectors, the heat-sealing and electrically insulating material filling at least partly the cells of the honeycomb while interconnecting the two layers or leafs.
