Abstract
An electrochemical pouch cell is for an electrical energy storage device, in particular intended for a motor vehicle. The electrochemical cell includes a stack of a plurality of electrodes, at least one electric terminal and a liner connected to the electric terminal and to itself, respectively at a primary connection and a secondary connection, so as to form a recess into which the plurality of electrodes and all or part of the at least one electric terminal extend, the electric terminal having a first dimension substantially equal to or greater than a first dimension of a stack of the plurality of electrodes.
Claims16
An electrochemical pouch cell for an electrical energy storage device, the electrochemical cell comprising:
- a stack of a plurality of electrodes;
- a liner;
- at least one electrical terminal comprising a base produced in an insulating material and an electrical connector extending along a first axis, the base of the electrical terminal having a first dimension on a second axis substantially equal to or greater than a first dimension on the second axis of the stack of the plurality of electrodes, said second axis being orthogonal to said first axis, the at least one electrical terminal and the liner contributing to delimiting a housing in which the plurality of electrodes extends;
- at least one primary link of an end portion of the liner to a perimeter of the base of the at least one electrical terminal;
- a secondary link of an end lateral portion of the liner to an opposite end lateral portion of the liner, that is distinct from the end portion and at least one spacing member disposed in the housing, and interposed between the plurality of electrodes and the at least one electrical terminal, the spacing member comprising at least one void configured to receive at least one tongue of at least one electrode, wherein the spacing member has a cellular structure, the cellular structure comprising cells, in a vacuum, configured to accommodate a gas produced during the operation of the electrochemical cell.
