NOVELTY - A battery comprises first and second laminate layers having perimeter and central regions; central chamber (112) formed by the central regions of the first and second laminate layers; anode, cathode, electrolyte; and two electrically conductive connector strips positioned between two perimeter regions (111).    USE - The battery is used as arsenic batteries, lithium (Li) ion batteries, Li polymer, or Li metal batteries.    ADVANTAGE - The invention has improved sealing of the connectors and improved barrier performance to water vapor intrusion and electrolyte migration. It has thinner laminates, and side seals that are easier to fold than conventional one. It has improved thermal resistance to high temperatures, and is a safer product and it allows for a maximized flexibility in sealing tabs (110) sizes and thickness by varying amount and location of hot melt material.    DETAILED DESCRIPTION - A battery comprises: first and second laminate layers having perimeter and central regions; central chamber formed by the central regions of the first and second laminate layers; anode, cathode, electrolyte arranged in an electrical current producing and conducting in the central chamber; and two electrically conductive connector strips positioned between the two perimeter regions, one end of the connectors for connection to an anode in the chamber, one end of the other connector adapted from connection to a cathode in the central chamber, each other end of the connectors extending beyond the perimeter regions of the laminates. The first and second laminate layers each comprises metal foil, outer polymer layer bonded to one side of the metal foil, and hot polymer coating on the other side of the metal foil in at least perimeter region of the metal foil. The hot melt polymer coatings in the perimeter regions of the first and second laminate are sealed together.    An INDEPENDENT CLAIM is also included for a battery packaging comprising the above invention.    DESCRIPTION OF DRAWING(S) - The figure shows a top view of a Li ion battery.
