PVDF Homopolymer ER602 is a specialized polyvinylidene fluoride (PVDF) powder widely used as a binder for electrode materials in lithium-ion battery manufacturing. As an adhesive material, PVDF offers excellent chemical stability and temperature resistance, providing strong adhesion to ensure a stable connection of electrode material particles.
The key function of PVDF in lithium-ion batteries is to firmly bond active material particles together and ensure their good contact with the current collector, maintaining stability in the battery's electrochemical environment and thereby enhancing the battery's overall performance and lifespan.

The main role of PVDF (polyvinylidene fluoride) binder in lithium battery electrodes is to firmly bond active materials, conductive agents and other components together to form a uniform and stable electrode structure, preventing the materials from falling off during the charging and discharging process. It has excellent chemical stability, high temperature resistance and electrolyte compatibility, which can effectively improve the mechanical strength and cycle life of the electrode, ensuring the transmission efficiency of lithium ions in the electrode and the long-term stability of the battery.
