New Electro-Rite® Technologies For Battery Cell Construction

Advanced Polymer Technology Staged To Deliver Extended Life and Performance to Lithium-Ion Batteries

CLEVELAND, Ohio – Lubrizol introduces new Electro-Rite® Polymer Technology for lithium-ion battery-cell construction to deliver exciting new performance capabilities. The technology includes polymers designed to improve performance of electrodes, separators, and electrolyte components. Specifically, Electro-Rite polymer technology can help enhance binder slurry formulation, aid in the formulation of advanced anodes and separators, and deliver new primer capabilities. Some early products from this new technology include:

• Electro-Rite® BD020 polymer provides combined binder and dispersion capabilities to silicon, silicon oxide, graphite and ceramic particles commonly used in separators and anode coatings. It can also be used for the preparation of electrode primers to improve overall battery performance.
• Electro-Rite® BD040 polymer is a unique wetting aid for dispersion of silicon, silicon oxide, graphite and carbon nanotube particles designed to improve energy density and life of lithium-ion batteries.
• Electro-Rite® AL003 polymer is a highly efficient aqueous suspension aid and rheology modifier that delivers superior control during coating process.
• Electro-Rite® BB002 polymer is a unique binder component that imparts outstanding flexibility in separator coatings for lithium-ion batteries.
• Electro-Rite® BB003 polymer is a unique binder component that enhances adhesion of ceramic coatings to polyolefin films used as separators in lithium-ion batteries.

“These polymer technologies are advanced material solutions designed to improve performance of various battery components”, shares Luis Carthery, global business development director, Lubrizol Performance Coatings. “Lubrizol has provided solutions for alkaline batteries for decades, and we're now excited to help battery manufacturers address the very different challenges and opportunities inside lithium-ion batteries."

As global demands for energy storage continue to expand, lithium-ion battery systems must evolve. With a commitment to its new Electro-Rite Polymer Technology, Lubrizol is dedicated to innovating advanced binder and dispersant technologies for anode, cathode and separator components to improve energy density and extend battery life. Together, Lubrizol and battery manufacturers can help enhance the lives of millions of people by advancing the way they move, connect and interact.
