Abstract: The present invention is a biobased homogeneous composition including a biobased polymer and a biobased wax, wherein the biobased wax comprises less than about 20% of the biobased homogenous composition. The biobased composition has a modulus of elasticity of at least about 0.5 GPa and a strain energy density of at least about 0.1 mJ/mm3.

Abstract: A thermal management assembly is described comprising a first thermal pathway comprising a first expandable material disposed between a first electrochemical cell and a first heat exchange member; and a second thermal pathway comprising a second expandable material disposed between a second electrochemical cell and a second heat exchange member. The first and second expandable material independently comprise intumescent particles dispersed in an organic binder and the first and second expandable materials expand at a first expansion temperature range and a second expansion temperature range respectively. Also described are methods of using of a thermal management assembly and methods of making a thermal management assembly.
