Bipolar electrochemical cell with improved casing

摘要

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.
