A power storage device packaging material including at least a substrate layer, an outer adhesive layer, a barrier layer, and a sealant layer in this order, wherein a difference in linear expansion coefficient at 20 to 150° C. between the substrate layer and the barrier layer is 20×10.sup.−6/° C. or less in both an MD direction and a TD direction.

Battery life cycle management is facilited with distinct visual cues of colors and color-coded combinations. The color-codes enable battery types and characteristics over the course of the life of the battery to be determined. The color-codes are based on a color system that indicates a performance rating of the batteries. A system for managing the color-coded batteries selects color-coded batteries for use based upon color, maintaining color based functionality, and color-coded battery indication for destruction of the battery at the end of its life cycle.
