Abstract
Temperature-sensitive thermal insulators for batteries are provided for. The thermal insulators are fabricated from barrier film and have one or more expandable chambers containing a fluid. The fluid has a vaporization temperature of from about 90.degree. F. to about 200.degree. F., preferably from about 100.degree. F. to about 130.degree. F. The insulator has a first volume above the fluid vaporization temperature which is greater than a second volume of the insulator below the fluid vaporization temperature.
