摘要

Title: Ceramic-based composite material impregnated with a phase change material and flame-retardant fillers and provided with two flame-retardant layers, as well as its manufacturing process A composite material comprising a porous support (1) based on ceramic in which the pores (3) of the porous support comprise at least one phase change material (4) and at least one type of flame retardant fillers (5), the porous support having two faces, each face being coated with a flame retardant layer (2a , 2b). A process for preparing this composite material. A battery (6) comprising: (i) a box (7) having a bottom and several side walls, (ii) at least two electrochemical cells (8-1, 8-2, 8-3), and (iii) the composite material, said composite material being disposed between said at least two electrochemical elements, and / or between the bottom of the case and at least one electrochemical element, and / or between one or more of the side walls and at least one electrochemical element. This composite material combines the properties of good thermal management during normal operation of the elements and a thermal barrier against the propagation of thermal runaway.
