| 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. |
