Carbon foams for thermal management
WebLikewise, carbon fiber is very lightweight—and it can withstand extremely high temperatures, a necessity when lithium-ion cells can reach 1,800 °F in thermal runaway. Because heat exchangers need a large surface area to transfer heat, the company built its TRS using carbon-fiber processed into velvet, a material pioneered by Knowles. http://www.cfoam.com/wp-content/uploads/Carbon-Foams-amp16111p029-3.pdf
