Patent ID: 7141332

Claim:
Prismatic packaging structure for electrochemical devices which comprises a rectangular cross section hard metal tubing having inside and outside surfaces, and front and back ends, having at least on said inside surface of said tubing a heat sealable plastic layer, a rectangular metal back end plug having inside and out surfaces, and having at least, on said outside surface of said back end plug a heat sealable plastic layer, a rectangular heat sealable plastic front end plug having embedded and sealed metal terminals therein, and having front surface, said front surface of said front end plug having attached a metal layer, said metal terminals passing through said front end plug and without contact with said metal layer, an electrochemical device inserted into said tubing and electroconductively connected to said terminals, said plugs inserted into said tubing's front and back ends, said heat sealable plastic layer on said tubing is in contact with said heat sealable plastic layer on said back end plug and with said heat sealable plastic front end plug, whereby said plastic layers and said plug can be heat sealed and bonded together to enclose and contain said electrochemical device.
