Multiflex-NR9
Category: Mechanical/Materials
Developers: Nano and Advanced Materials Institute
Product Description:NAMI has developed Multiflex-NR9, a PVDF (Polyvinylidene fluoride) binder functionalized with AMPS (2-acrylamido-2-methylpropanesulfonic acid), specifically engineered to overcome nickel-rich cathode challenges. By integrating pH-stabilizing sulfonic acid groups (–SO₃H) and metal-chelating sulfonates (–SO₃⁻), Multiflex-NR9 prevents slurry gelation, enhances electrode adhesion and improves long-term cycling stability—enabling high-energy, high-rate lithium-ion batteries. NAMI's AMPS-modified PVDF binder improves nickel-rich cathode performance in lithium-ion batteries. By incorporating AMPS (2-acrylamido-2-methylpropane sulfonic acid) through ozone/plasma-induced grafting techniques, this binder delivers unparalleled slurry stability, extending processing time from hours to 10 days by neutralizing residual lithium compounds and preventing particle aggregation. The sulfonic acid groups provide dual functionality—buffering slurry pH while chelating transition metal ions to prevent battery degradation. The modified PVDF exhibits enhanced adhesion strength, maintaining electrode integrity through rigorous cycling. This translates to improved electrochemical performance: 93% capacity retention after 500 cycles at 3C rates and 90% retention after 1000 cycles, significantly outperforming conventional binders. The technology enables reliable production of high-energy-density batteries with improved fast-charge capability and cycle life. NAMI's technology could address manufacturing challenges in nickel-rich systems, offering battery producers a complete solution combining processing advantages and long-term performance. This binder could represent an enabler for next-generation electric vehicles and energy storage batteries, where energy density and durability are paramount. The technology remains compatible with existing production processes while delivering measurable improvements in yield and consistency.
