In 2025, China accounted for 68% of global new energy vehicle sales. Nearly 60% of Chinese consumers expressed willingness to purchase new energy vehicles. Existing fuel vehicle owners indicated higher requirements for new energy vehicles when considering a replacement, with safety, quality, charging convenience, and driving range being the four core factors.

Battery safety and lifespan are among the key factors restricting the development of new energy vehicles, as well as one of the major concerns for consumers when considering such purchases. Under extreme and persistent high or low-temperature conditions, the driving range of new energy vehicles tends to decrease, while energy consumption increases. Moreover, terms like "spontaneous combustion" and "catching fire" are frequently highlighted in media reports following accidents, reflecting users' deep-seated anxieties regarding safety. Therefore, reducing or eliminating battery safety risks is a critical direction that all automotive manufacturers and related industries must strive toward.

Thermal management materials can rapidly dissipate heat generated during charging and discharging to cooling components, while providing comprehensive protection for batteries against liquids, harsh environments, vibration, and thermal shock.

Thermally conductive polyurethane structural adhesives BN-PU6012 and BN-PU6003 are used for thermal conduction and structural bonding between battery cells and cooling plates, as well as between cells and housing. They offer high bonding strength, excellent toughness, along with aging and chemical resistance, enabling low-cost and rapid battery assembly.

Flame-retardant insulation sheets BN-FP are applied between battery cells, providing outstanding flame retardancy, aging resistance, mechanical strength, and electrical insulation properties.

Thermal pads from the BN-FS series are used for gap filling and heat dissipation between housing and PCB components. By eliminating air gaps and reducing interfacial thermal resistance, these pads enhance thermal performance and reliability.
