ABSTRACT:
The present invention pertains to lightweight, hard and leakproof prismatic packaging structures for electrochemical devices and economical method of assembly and hermetic sealing of said structures by plastic layers attached to their metal walls. Metal welding is avoided and superior protection of lithium polymer cells and other cells is thus provided at lesser cost.
