Trinseo launches "fourth-generation" SBR battery binder platform

Wayne, Pennsylvania — Trinseo has launched a fourth-generation styrene-butadiene rubber (SBR) binder platform for next-generation lithium-ion batteries for electric vehicle (EV) and energy storage system (ESS) applications.

Developed in “deep collaboration with global battery manufacturers,” the technology is designed to address demand for higher energy density, improved durability and greater production efficiency.

According to Trinseo, the new SBR binder technology delivers up to 30% higher peel strength compared with conventional SBR binders, enabling stronger electrode adhesion, thicker coatings and faster coating speeds.

The first product introduced under the platform is Voltabond 109 latex binder, which Trinseo said offers “excellent rebound control” and compatibility with both graphite and low-to-medium silicon anodes, supporting a range of cell designs and manufacturing conditions.

The company said the platform also offers enhanced high-temperature stability and low internal cell resistance, supporting faster charging and long-term performance.

Trinseo will produce the materials across Asia-Pacific, Europe and North America, to ensure supply resilience and meet regional demand.

The company said the platform builds on its long-standing expertise in emulsion polymerisation and battery binder technologies and will serve as a basis for further product launches across the global battery value chain.
