Proposal of fire-resistant and heat-insulating design of enclosures based on Fire Safety Hazard No. 200, along with measures to prevent thermal runaway propagation between cells, categorized by application.
In lithium-ion batteries, the thermal propagation measures required differ between the storage box and the outer casing and the internal cells and modules. Silsaam offers a lineup of thin insulation panels called "Silsaam Panel (FR)" that can be integrated into side walls, ceilings, doors, and partitions, as well as ultra-thin heat insulation materials called "Silsaam Shilshin" used between cells, within modules, and inside battery packs. Both have a proven track record in applications related to energy storage and batteries. The micro-porous insulation material exhibits low thermal conductivity at high temperatures, contributing to space-saving and lightweight designs of the casing, suppression of thermal propagation to adjacent cells, and accommodating cell expansion. The performance related to Fire Safety Regulation No. 200 is evaluated for the entire casing, including steel plates, doors, openings, and joints.

Applications/Examples of results
■Examples of Use - Battery storage boxes, cubicle-type battery systems, container-type battery systems - Heat insulation for side walls, ceilings, doors, partitions, and battery rack areas - Barriers between prismatic/pouch cells, pads within modules, inside battery packs - Backup power supply systems for factories, data centers, etc. ■Track Record Silsaam Panel (FR) has been adopted for fire-resistant and heat insulation applications for the side walls, ceilings, doors, and partitions of battery storage boxes and enclosures. Silsaam Silshin is used as a thermal propagation countermeasure and compression member between lithium-ion battery cells, within module pads, and inside battery packs. Thickness, dimensions, coating specifications, and processing methods are individually considered according to the application.

Company information
**What is Micro-porous High-Performance Insulation Material?** ♦ It boasts insulation performance superior to still air, making it the world's most outstanding high-performance insulation material. ♦ It is called "micro-porous" due to its internal structure containing nano-level pores. ♦ Composed of amorphous silica particles with a diameter of approximately 5 to 25 nm, infrared reflective materials such as silicon carbide, and inorganic filaments, it is safe for the environment and human health. ♦ With a high heat resistance and made entirely of inorganic materials, it also serves effectively as an excellent fire protection material. ♦ Depending on the industry, it is referred to by various names such as "super high insulation material," "high-performance insulation material," and "micro-pore insulation material." **About Silsaam Japan** ♦ We consistently manufacture from the raw material fumed silica to the final product of micro-porous insulation materials. ♦ Our strength lies in providing high-quality, low-cost, and high-value-added products to our customers. ♦ We actively engage in product development of insulation and fireproof materials using fumed silica, offering comprehensive solutions to various challenges faced by our customers.
