HNBR is diversifying its uses and entering the lithium-ion field

HNBR can be applied to battery binder, dispersant, solid state electrolyte in lithium battery field, and other application areas are being researched and broken through.

Battery binder is an important component in lithium-ion batteries, which has a significant impact on the electrochemical performance of the battery. HNBR has excellent performance as a lithium-ion battery binder and is a potential alternative to PVDF, with excellent mechanical properties, adhesion, electrochemical stability, cycling performance, and at the same time lower cost.

Dispersant is an important component of the slurry, due to the uneven dissolution of the conductive agent in the electrode slurry composition, the particles are prone to inter-particle dispersion or agglomeration, resulting in a decrease in the internal homogeneity of the slurry, which affects the service life of the finished battery and has a potential safety hazard. Therefore, it is necessary to add dispersants to the slurry to promote the dispersion of various particles. Zeon and LG have relevant patents certified, confirming the feasibility of the application of HNBR in the field of dispersants. It is expected that the market size of PVDF in lithium applications will reach more than 100,000t in 2025, HNBR replacement is promising.

Electrolyte is one of the core components of the battery, it is the medium of ion movement and current conduction between positive and negative electrodes of the battery, and its quality directly affects the energy density, service life and cycle performance of the battery.

HNBR is expected to be used in the manufacture of ideal solid-state battery electrolyte, there are already successful examples in the laboratory, with the innovation and breakthrough of battery technology, the future development space can be expected.
