Binders and their Importance in Li-Ion Batteries

When it comes to the performance of lithium-ion batteries, binders play a crucial role in ensuring optimal functionality. These binders facilitate the dispersion and adhesion of electrode species to the current collector, enhancing the overall performance, capacity, and cycle stability of the batteries.

One popular type of binder used in li-ion batteries is the PVDF binder. PVDF, or Polyvinylidene Fluoride, is renowned for its excellent adhesion properties, thermal stability, and chemical resistance. PVDF binders are widely employed in li-ion batteries due to these advantageous features.

By utilizing PVDF binders in the battery manufacturing process, manufacturers can ensure the electrodes adhere firmly to the current collector. This helps minimize electrode detachment or degradation during the charge-discharge cycles, leading to improved battery performance and longer lifespan.

Aside from PVDF binders, there are various other binders used in li-ion batteries, such as carboxymethyl cellulose (CMC), styrene butadiene rubber (SBR), and polyacrylic acid (PAA). However, PVDF remains a popular choice due to its superior properties.

Aqueous binders have gained attention in recent years due to their advantages, such as lower cost, improved battery safety, and environmental friendliness. These binders, including PVDF-based aqueous binders, offer an alternative to the conventional solvent-based binders, reducing potential hazards associated with the manufacturing process.

Performance of PVDF Binder in Li-Ion Batteries

PVDF binder plays a crucial role in enhancing the performance of lithium-ion (Li-ion) batteries, particularly when used with graphite anodes. The combination of PVDF binder and graphite provides efficient binding and improves the overall battery capacity.

However, when PVDF binder is used with silicon anodes in composites, it encounters a significant challenge in terms of capacity failure. This is primarily due to the loss of connectivity between the graphite, silicon, and PVDF binder during battery cycling.

The performance issue of PVDF binder in silicon anodes can be attributed to the chemical decomposition that occurs within the battery system. Various studies have identified that the decomposition of PVDF binder is particularly noticeable in composite electrodes, as well as in silicon-only and graphite-only electrodes.

The decomposition process is catalyzed by the presence of lithium fluoride (LiF), which acts as the major decomposition agent in the PVDF binder. The reaction between LiF and PVDF binder negatively impacts the battery performance, leading to reduced capacity and overall efficiency.

To address these challenges and improve battery performance, researchers have been exploring alternative chemically interactive polymer binders for composite electrodes. These binders offer improved stability and enhanced connectivity between the electrode materials, leading to better battery performance and longer cycle life.
