Protective multilayer laminate for covering an electrochemical device

A laminate, for use as a protective, insulating covering or wrap for an electrochemical battery or cell, the laminate capable of inhibiting transport of electricity, oxygen, and water therethrough which comprises:

• a. a first layer which is a metal-containing ionomeric cross-linked ethylene acrylic copolymer, said layer forming a heat seal when two panels of the laminate are heat sealed together to form said covering or wrap;
• b. a second layer which is low density polyethylene layer;
• c. a third layer which is a nylon layer;
• d. a fourth layer which is a second low density polyethylene;
• e. a fifth layer which is an aluminum foil layer;
• f. a sixth layer which is a third low density polyethylene layer;
• g. a seventh layer which is a second nylon layer;
• h. each of said polymeric layers being essentially devoid of hydroxide pendent groups;
• i. an oxygen scavenger incorporated in one of said polymeric layers or disposed between layers of said laminate;
• and wherein
• j. said second layer is between said first and third layers;
• said third layer is between said second and fourth layers;
• said fourth layer is between said third and fifth layers;
• said fifth layer is between said fourth and sixth layers;
• and said sixth layer is between said fifth and seventh layers.
