A battery cell comprising:
- a sealed foil pouch having a plurality of openings;
- a terminal block disposed within the sealed foil pouch, the terminal block having a plurality of terminals extending outwardly therefrom, each of the plurality of terminals extending through one of the plurality of openings.
A method of manufacturing a battery cell comprising the steps of:
- a) forming a plurality of foil laminate openings in a foil laminate;
- b) engaging a terminal block with the foil laminate, the terminal block having a plurality of terminal openings formed therein;
- c) folding the foil laminate over the terminal block such that each of the plurality of terminal openings communicates with one of the plurality of foil laminate openings;
- d) sealing two sides of the foil laminate on either side of the terminal block, leaving an open side of the foil laminate disposed away from the terminal block;
- e) inserting a stack of terminal electrodes through the open side, the stack of terminal electrodes having a plurality of terminals, each of the plurality of terminals extending through a respective one of the terminal openings and foil laminate openings;
- f) sealing the open side, forming a pouch;
- and
- g) inserting an electrolyte into the pouch.
