BIPOLAR ELECTROCHEMICAL BATTERY WITH AN IMPROVED CASING

摘要

The invention relates to novel casing for a lithium bipolar electrochemical battery (A) including a bipolar element. According to the invention the casing is formed by a composite material including a matrix and at least one porous reinforcement the matrix of which includes at least one hardened polymer with which the porous reinforcement(s) are impregnated. The porous reinforcement(s) (4) and the hardened polymer(s) (5) encase the bipolar element (1) and maintain a predetermined pressure on either side of the latter so as to maintain a predetermined contact between the components thereof.
