Abstract
AbstractAmong the various configurations available for lithium-ion cells, the pouch type has been grabbing attention because of its high energy density, design flexibility, low cost and lightweight. Such a pouch pack enables further reduction in the size and weight of portable electronic devices where they power and for the same reason the pouch cells are not only suitable for terrestrial applications but also attractive for space applications too. Lithium-ion pouch cells have been successfully used in many applications including space. However, this design has certain limitations. The poor rigidity of the pouch case makes them more susceptible to external mechanical damage and swelling under elevated temperature and overcharging. Therefore, the manufacturers are constantly striving to improve the performance of pouch cells. This chapter provides a brief overview about the different aspects of lithium ion pouch cells and the various strategies introduced in upgrading the performance of this thin design.KeywordsPouch cellComposite trilayerTab location
