1. A composite thermal management sheet for a battery, the composite thermal management sheet comprising:
a single silicone foam layer; and
a reactive filler composition disposed within the single silicone foam layer, the reactive filler composition comprising
a first filler that decomposes to generate water upon initial exposure to heat; and
a second filler different from the first filler, wherein the second filler forms a thermal barrier layer with a decomposition product of the first filler, or absorbs the water, or both,
wherein the composite thermal management sheet is a single layer and does not comprise another layer on the single silicone foam layer.
