Endothermic composite article
An energy storage device housing comprises an inorganic composite comprising an inorganic binder comprising a layered double hydroxide (LDH) and a plurality of inorganic endothermic particles distributed within the inorganic binder. The endothermic particles are present in a range from 30-98 wt% based upon the total weight of the endothermic particles and the inorganic binder, and the composite has an endotherm of greater than 200 J/g. The sum of endothermic particles and the inorganic binder comprises at least 60 wt% of the total weight of the composite. Also claimed is the inorganic composite material per se. The layered double hydroxide may be a member of one or more of the hydrotalcite, quintinite, fougerite, woordwardite, cualstibite, glaucocerinite, wermlandite and hydrocalumite groups but is preferably Mg6Al2(OH)16CO3.4H2O. It may be an intercalated or hydrophobicised layered double hydroxide. The composite may include up to 40 wt% additives relative to the weight of the inorganic binder, which may comprise an intercalating agent, e.g. sodium gluconate, for intercalation in the layered double hydroxide. The endothermic particles may comprise a coating of the inorganic binder. A method of preparing the material by forming, shaping and drying a paste is also described and claimed.
