Rechargeable batteries play an increasingly key role in energy storage for a range of applications from transportation to hand held devices. Synthomer is pleased to offer a range of high performance raw materials designed to ensure cells offer high charge capacity, reliability and battery life.
Anode binders hold together the active material (e.g. graphite or silicon) and adhere it to the copper current collector. For performance and safety reasons these bonds must be maintained throughout the battery’s life. Styrene butadiene rubber (SBR) has become the most widely use lithium-ion anode binder due to its balance of versatility and electrochemical performance. Synthomer is pleased to offer SBR binders that have been engineered to meet the demanding needs of cell manufacturers. This ensures they are a drop-in to existing manufacture processes and offer excellent battery performance.
Synthomer’s Litex LB SBR binders are supplied as ready to use water based latexes that have excellent formulation compatibility with graphite and other anode actives. They offer excellent process stability ensuring that they are able to withstand anode mixing processes whilst minimising manufacture losses.
Litex LB binders have been optimised to provide excellent adhesion to active materials and to copper. This ensures they retain the bonds between active material and current collector over a lifetime of charge and discharge cycles, so that the battery keeps its capacity for longer. Synthomer offers grades tailor made to maximise conductivity and for performance at low temperatures.
With the support of its world class manufacturing and logistics network Synthomer is supplying customers around the globe with SBR binders for use in electric vehicles (EVs), energy storage and hand held devices (3C).
- Easy to use and compatible with standard industry manufacturing processes.
- Outstanding electrode adhesion and mechanical properties.
- Excellent electrochemical performance.
- High capacity battery cells with excellent capacity retention.
