AI Technical Summary
Existing insulation materials have high thermal conductivity in high-temperature regions, which cannot effectively suppress heat transfer between battery cells. Furthermore, the matrix resin may melt at high temperatures, resulting in poor shape retention and powder shedding.
An insulating sheet containing a first inorganic particle and a second inorganic particle is used. The first inorganic particle has a specific particle size distribution and refractive index, and the second inorganic particle is a nanoparticle. Combined with inorganic fibers of different properties, an interwoven network structure is formed to improve mechanical strength and shape retention.
It effectively reflects radiant heat over a wide temperature range, suppresses conductive and convective heat transfer, maintains the shape and structure of the insulation sheet, prevents powder shedding, and reduces the chain reaction of thermal runaway.
