摘要

Electrochemical accumulator, in particular a metal-ion accumulator, with flexible packaging incorporating one or more cooling fluid passage orifices, associated module and manufacturing method. The invention relates to an electrochemical accumulator (A), in particular a metal-ion accumulator, comprising at least one electrochemical cell and a flexible packaging (6) arranged to contain with sealing the at least one electrochemical cell while being traversed by part of the electrochemical cells. current collectors forming the output terminals (4, 5) of the accumulator, the flexible packaging incorporating in an area beyond the electrochemical cell (s), at least part of at least one rigid insert (10) of electrically insulating material at least for its portion (s) inside the flexible packaging, the insert being in the form of a hollow tube internally delimiting an orifice (8 ) coolant passage.
