SBR: Beyond Binding
While SBR is primarily known for its binding properties, its influence extends to other critical aspects of battery performance.
Improving Low-Temperature Performance
One of SBR’s benefits is its ability to enhance battery performance in cold conditions. By improving the electrolyte’s wettability, SBR facilitates lithium-ion movement within the battery, leading to better discharge rates at low temperatures.
Addressing Electrode Expansion
SBR’s elasticity can impact the expansion of the negative electrode. While some elasticity is desirable for flexibility, excessive expansion can negatively affect battery performance. Researchers are exploring ways to optimize SBR’s properties to balance elasticity and dimensional stability.
Conclusion
SBR is a multifaceted component in lithium-ion battery production. Understanding its role and properties is crucial for developing high-performance batteries. Ongoing research and development are focused on further optimizing SBR’s contribution to battery technology.
