1. A battery module comprising:
a first battery cell and a second battery cell;
a heat control member comprising:
a first layer of a fiber reinforced aerogel composition having a first outer surface and a second outer surface opposite the first outer surface, the fiber reinforced aerogel composition including an opacifier present at a level of at least about 5 to 20 percent by weight of the fiber reinforced aerogel composition;
a polymer compliant member disposed on a side of the first layer of the fiber reinforced aerogel composition corresponding to the first outer surface, the polymer compliant layer comprising one or more of polyolefins, polyurethanes, phenolics, melamine, cellulose acetate, and polystyrene; and
a thermally conductive material layer between the first layer of the fiber reinforced aerogel composition and the polymer compliant member;
wherein:
the second outer surface of the first layer of the fiber reinforced aerogel composition is disposed adjacent to the first battery cell.
