As electric vehicles (EVs) and energy storage systems evolve, so does the demand for reliable, high-performance battery materials. UBE responds to this global challenge with a wide range of advanced solutions designed to enhance the efficiency, safety, and lifespan of next-generation lithium-ion batteries.
UBE’s contribution to battery innovation spans across multiple critical components. In cell construction, UBE manufactures cell separators—porous polyolefin films and ceramic-coated versions—that prevent internal short circuits while enabling smooth ion transport. These materials are essential for stable charge and discharge performance under demanding conditions.
In addition, UBE supplies highly purified electrolyte base materials and additives that improve interface stability and help prevent overcharge, enhancing both battery safety and performance. To ensure mechanical integrity within cells, binders such as polyimide varnishes play a crucial role in preventing electrode disintegration over time.
UBE’s materials also support thermal management systems in EVs. From cooling tubes and connectors that ensure heat dissipation, to gap fillers based on polyurethane precursors, these components are engineered to keep battery packs within optimal temperature ranges, avoiding performance losses due to overheating.
For structural battery pack components, UBE provides lightweight thermoplastics that offer high mechanical strength, design flexibility, and efficient processing—crucial for meeting EV weight reduction targets. Additionally, polyimide coatings and polyamide films help insulate and protect modules and busbars, ensuring electrical safety and resistance to environmental stress.
With more than a century of expertise and a global presence, UBE continues to deliver tailored polymer solutions for the evolving mobility landscape.
