Abstract
A composite thermal management sheet for a battery includes a silicone foam layer; and a reactive filler composition disposed within the silicone foam layer, the reactive filler composition including 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.
Claims20
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.
A composite thermal management sheet for a battery, the composite thermal management sheet comprising:
- a silicone foam layer;
- and
- a reactive filler composition disposed within the 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 comprising a borosilicate glass layer with a decomposition product of the first filler,
- wherein the composite thermal management does not comprise another layer on the silicone foam layer.
A composite thermal management sheet for a battery, the composite thermal management sheet comprising:
- a silicone foam layer;
- and
- a reactive filler composition disposed within the silicone foam layer, the reactive filler composition
- comprising borax and hydrous sodium silicate, or
- comprising aluminum trihydrate, zinc borate, and hydrous sodium silicate, or
- comprising borax and zinc borate, or
- comprising borax, zinc borate, and aluminum trihydrate, or
- comprising a superabsorbent polymer, or
- consisting of aluminum trihydrate and zinc borate,
- wherein the composite thermal management does not comprise another layer on the silicone foam layer.
