Abstract
A composite thermal barrier material (100) has a sandwich structure, and comprises an inner layer (110) consisting of an aerogel material which has ultra-low thermal conductivity; and two flame retardant layers (120) which comprising a flame retardant resin matrix (130), wherein the inner layer (110) is sandwiched by the two flame retardant layers (120), and the flame retardant layer (120) also contains an expandable graphite (140), a high temperature decomposable material (150) and a phase change material (160) as functional fillers dispersed in the flame retardant resin matrix (130). The composite thermal barrier material (100) has excellent thermal insulation property, and may stop the thermal propagation when one cell has thermal runaway.
