Abstract
Battery thermal management materials, compositions and systems are provided. Exemplary embodiments include a battery thermal management member. The battery thermal management member can include a heat protection layer and a resilient layer. Also provided are methods of preparing or manufacturing such battery thermal management members. In certain embodiments, the heat protection layer can include mica, microporous silica, ceramic fiber, mineral wool, aerogel or combinations thereof.
Claims10
A battery thermal management member comprising:
- a first heat protection layer comprising an aerogel composition;
- a second heat protection layer comprising the aerogel composition;
- wherein the aerogel composition includes a fiber reinforcement material,
- wherein each of the first heat protection layer and the second heat protection layer is completely encapsulated with a first encapsulation member and a second encapsulation member, respectively, and
- at least one compressible resilient layer including one or more organic materials with a temperature of chemical decomposition greater than 280° C.,
- wherein each of the first and second heat protection layers has a thermal conductivity less than about 65 mW/mK,
- wherein the first and second heat protection layers maintain at least a surface of the compressible resilient layer below a chemical decomposition temperature of at least one of the one of the more organic materials,
- wherein the first encapsulation member of the first heat protection layer is in direct contact with a first side of the at least one compressible layer and the second encapsulation member of the second heat protection layer is in direct contact with a second side of the least one compressible layer, wherein the first side is opposite the second side, and
- wherein portions of the first encapsulation member and the second encapsulation member are the outermost layers of the battery thermal management member.
