The invention relates to a material including a support consisting of a porous composite material including at least one polymer phase forming a binder based on at least one polymer selected from thermoplastic polymers, elastomers, and elastomer thermoplastics, and at least one filler selected from thermally conductive fillers, the pores of the support consisting of the porous composite material being partially or entirely filled with at least one phase-change material. The invention also relates to a method for producing said material.

Heat storage matertal

Provided is a process for the degradation of at least one polymer of an alkene carbonate, a polymeric composition for a lithium-ion battery electrode having a degradation residue obtained by this process, a process for the preparation thereof, an electrode and a battery incorporating it and a degradation process for the sintering of ceramics. The degradation process includes a reaction at 120&#xb0; C. and 270&#xb0; C., and under air of a primary amine with a poly(alkene carbonate) polyol, which depolymerizes it in order to obtain a non-polymeric degradation residue. This composition includes an active material, an electrically conductive filler, a polymeric binder and a residue from the degradation under air between 120&#xb0; C. and 270&#xb0; C. of a sacrificial phase which includes the polymer and which has been melt blended beforehand with the active material, with the filler and with the binder in order to obtain a precursor mixture of the composition.
