PVDF Solutions for Lithium Ion Battery | Arkema High Performance Polymers

Arkema is pioneer in development of advanced materials for battery technology and our high-performance PVDF materials for battery cell manufacturing serve battery industry for decades. Our Kynar® PVDF solutions have been used in lithium-ion battery technology for many years as electrode binders for active materials in cell manufacturing. Our continued innovation has led to solutions that are now being used for both anode & cathode binders and separator coatings inside the battery cell.

Tailor-Made Performance

Arkema has been a pioneer in the development of high performance PVDF resins and flexible copolymers for several decades. Our proprietary process allows careful tailoring of molecular weight, particle size, crystallinity, and functionality.

Emulsion PVDF was originally designed, more than 50 years ago for high-end construction coatings where a small particle size is required to get a high level of gloss and smooth surface finish.

Higher Surface Area = Easier Dissolution = Faster Processing.

Today, in battery applications, those small particles, combined with their unique aggregated structure, result in a fast dissolution rate into NMP or Acetone as opposed to large suspension particles where NMP diffusion into the beads may be extremely slow. The small particles are also key in enabling a revolutionary ‘dry process mixing’.

Binder Innovation

Binder innovation is at the core of our strategy in the battery market. Arkema is committed to an exciting future in binder development that will drive safer, higher-performing cells. Arkema’s King of Prussia battery innovation hub in the USA leads the way and we invite customers to collaborate with us as we push the boundaries of cutting-edge technologies (e.g. high nickel binders, waterborne solutions, dry process prototypes). Our team is also eager to assist from our satellite technical centres in China, France, Japan, and Korea.
