Abstract
A casing for a lithium bipolar electrochemical battery including a bipolar element. The casing includes a composite material including a matrix and at least one porous reinforcement, the matrix of which includes at least one hardened polymer impregnating the at least one porous reinforcement, wherein the at least one porous reinforcement and the at least one hardened polymer encase the bipolar element and maintain a determined pressure on either side of the bipolar element to maintain a determined contact between its constituents.

1-16. (canceled)
A bipolar lithium electrochemical battery comprising:
- at least one bipolar element;
- and
- a casing encapsulating the bipolar element;
- wherein the casing includes a composite material, including a matrix and at least one porous reinforcement, the matrix of which including at least one hardened polymer impregnating the at least one porous reinforcement, wherein the at least one porous reinforcement and the at least one hardened polymer encase the bipolar element and apply a determined pressure to either side of the bipolar element, to maintain a determined contact between its constituents.
A method for producing a casing of a lithium bipolar electrochemical battery including a bipolar element, the method comprising:
- installing a subassembly including a bipolar element between two portions of at least one porous reinforcement impregnated by at least one polymer or one or more monomers in a mold;
- applying a determined pressure to either side of the two impregnated reinforcement portions of the subassembly in the mold, until the at least one polymer is hardened.
