Elaplus Case Sharing, solutions for bonding bottom cells of battery pack
In the design and manufacturing process of battery packs, the adhesion performance of battery cells is one of the key factors to ensure battery stability, thermal management, and mechanical strength. Especially in modern electric vehicles (EVs), energy storage systems, and other high-performance devices, efficient heat dissipation, mechanical protection, and safety of battery packs are particularly important. In order to meet these stringent requirements, Elaplus recommends using its SIPA 1865 two-component addition molding silicone gel to provide an efficient and reliable solution for bonding the bottom cells of battery packs. Customer requirements:▶ Thermal conductivity: 0.8w/m.k▶ Drying time: 40-60 minutes▶ Tensile strength: 0.8-1.2MPa▶ Viscosity: 30000 to 80000Recommended products: SIPA 1865RTV SIPA 1865A/B silicone sealant is a two-component addition molded room temperature cured silicone rubber that can also be heat cured to form a strong and soft high toughness silicone rubber elastomer. Easy to mix and pour during operation, it can cure at any thickness at room temperature, with no by-products evaporating during the curing process and minimal volume change. The cured material has a wide range of temperature resistance, excellent resistance to cold and hot alternation, aging, and electrical insulation, as well as good moisture resistance, earthquake resistance, corona resistance, and leakage resistance. This product does not require the use of other primers and can bond most materials such as metal, plastic, ceramic, and glass. For bonding special materials such as PP and PE, specific primers need to be used. Flame or plasma treatment can also be applied to the surface of the bonded material as needed to improve bonding performance.
