Composite material for heat storage, method for preparation and use
The invention describes a composite material for heat storage comprising a thermochemical material (TCM) encapsulated in a water vapor permeable polymeric material. The thermochemical material preferably comprises at least one salt, at least one salt hydrate or a mixture of these, wherein the salt is preferably capable of binding water in an exothermic reaction, such as calcium chloride. Encapsulation in a water vapor permeable polymeric material results in an improved stability, cyclability of the thermochemical material, a reduced regeneration temperature and reduced corrosion of the environment. The composite according to the invention is particularly suitable for energy storage, preferably in the field of building and construction, and more preferably in the seasonal storage of solar energy.
