ELECTROCHEMICAL ACCUMULATOR WITH PACKAGING COMPRISING AT LEAST ONE POLYARYLETHERKETONE (PAEK), AND ASSOCIATED FILM AND METHODS

摘要

The invention concerns a new flexible or rigid packaging for an electrochemical accumulator (A). The packaging contains at least one polyaryletherketone (PAEK) sheet, notably a polyetheretherketone (PEEK™) sheet. According to a preferred embodiment, a polyaryletherketone (PAEK) sheet incorporates within it at least one metal stud constituting one of the poles of the accumulator. The packaging is useful for the packaging of lithium-ion accumulators.
