Unmatched performance of PVDF for battery electrode binders

Market-leading electrode binder material 

The Kynar® HSV series of PVDF binders offer easy processing, high throughput, stable slurry viscosity, and very high adhesion through many cycles and wide temperature fluctuations. Lower binder loading can be achieved while maintaining high adhesion through Arkema’s careful control of the functionalization of the binder resin. This allows for higher concentrations of active materials, lower internal resistance, and high cohesion across the electrode. 

  • Kynar® HSV 900 >> the worldwide best-seller for LFP batteries
  • Kynar® HSV 1810 >> the functionalized PVDF designed for NMC batteries 


With high adhesion at lower loading levels, the Kynar® HSV series enables higher energy densities due to the increased active material content. HSV series binders also demonstrate low swelling levels in common solvents and electrolytes (even at high temperatures – up to 80ºC).

Active material compatibility

It is critical for binder solutions to provide high adhesion properties no matter what active material is being used. The Kynar® HSV series maintains excellent adhesion properties with LCO, LFP, LNMO, NMC, and NCA. Please contact our team for compatibility with other materials.


Balanced adhesion & flexibility

Retained performance after exposure to electrolyte is extremely important for the long-term performance of the battery cell. Batteries are also subjected to many mechanical stresses so binders that can maintain adhesion without cracking after being flexed are critical to serving the battery market of the future. Kynar® HSV 1810 exhibits outstanding flexibility compared to competitive binders on the market.

In this white paper, we delve into the dynamic world of battery electrode and separator coating manufacturing, examining the case of a new battery cell manufacturing process versus PVDF emulsion technology. Polyvinylidene Fluoride (PVDF), a well-established binder in the Lithium or Sodium-ion battery cell manufacturing industry, satisfies simultaneously the most pivotal material characteristics as a cathode binder or separator coating. 

The following are the important characteristics required for lithium-ion battery technology today:

1) High Electrochemical Resistance & High Purity

2) Mechanical stability

3) Processability
