  • POUCH CELL COMPRISING AN EMPTY-VOLUME DEFINING COMPONENT
    Publication number: 20130337304
    Abstract: Disclosed are pouch cells, for example lithium-ion pouch cells, where a portion of the inner volume of the pouch is substantially empty and there is subatmospheric pressure inside the pouch. In some embodiments gas released inside the pouch, for example during use of the cell, is accommodated in the substantially empty portion of the inner volume of the pouch, avoiding pouch bulging.
