Fluid Binders (Batteries)

The mainstream in the market currently uses PVDF (polyvinylidene fluoride) as a binder. In actual mass production, there is a tendency for PVDF to absorb electrolytes, leading to swelling and a decrease in bonding performance. It cannot effectively control the volume changes of particles during the charging and discharging process. At the same time, the organic solvent NMP (N-methylpyrrole) used in PVDF is volatile, flammable, explosive, and highly toxic. The volatility of NMP not only endangers the health of production workshop staff but also leads to significant environmental pollution and high recovery expenses.

Compared to solvent-based adhesives, water-based binder systems using terpene resin as a raw material have characteristics such as solvent-free release, environmental compliance, low cost, non-flammability, and safe use. They have become an important development direction for binders in lithium-ion batteries.
