High Performance Battery Binders, New Lightweight Thermoplastic Battery Casing Offer Enhanced Performance, Recycling Opportunity and Efficiency

• Innovative, lightweight thermoplastic battery casing enables recyclability, comparable performance characteristics of metal casing and short production cycle times as compared to metal casings
• VOLTABOND™ Water Based Latex Binders enhance battery life, charging speeds, range, and overall performance
• Dedicated battery binder lab opens in Rheinmunster, Germany

Trinseo (“Trinseo” or “the Company”) (NYSE: TSE), a specialty material solutions provider, today announced its lineup of EV Battery solutions that will be on display at The Battery Show Europe in Stuttgart, Germany, June 18-20, 2024, Hall 8, Booth D26. Two innovative technologies will be highlighted this year that focus on improving performance of the EV battery itself, along with a novel approach to physically protecting the battery pack.

The thermoplastic battery casing that will be showcased is produced using the Direct Long Fiber Thermoplastic (DLFT) molding process. This gives EV OEMs the option to move away from more expensive heavy rigid metal casings to high performance thermoplastic trays and covers, without compromising performance or protection. It also allows for shorter cycle times for high volume manufacturing, part toughness, along with structural flexibility and greater design freedom for complex part geometries. Lighter weight casing helps increase energy efficiency, and range in EVs as compared to metal casings. And using high performance thermoplastic offers increased design flexibility as compared to metal casing for innovative functional integration while providing electric insulation, heat insulation and fire resistance the industry demands.

“To us, the same principles of innovation, science, engineering, and design that define the external aesthetics of an electric vehicle, also apply to the internal components,” said Chief Technology Officer Han Hendriks. “In addition to the benefits of weight reduction, our thermoplastic casing material is available in grades containing recycled polycarbonate content produced by our in-house PC dissolution technology.”

Also on display is Trinseo’s VOLTABOND™ aqueous-based anode binder that binds the graphite and conductivity agent powder together and onto the foil current collector of a battery. VOLTABOND™ binders provide high peel strength, low DCIR and low re-bounce. In addition, its unique chemical structure enhances battery life by offering resistance to electrolyte dissolution.

“By improving electrical conductivity, structural integrity, cyclability, and energy density, with our VOLTABOND™ latex binders, we’re helping batteries last longer, charge faster, go farther and perform better,” added Hendriks. “At less than one percent of the battery’s weight, we can make a big impact on a number of performance characteristics that the industry is looking for.”
