Lead-Acid Battery Industry
Lead-acid batteries remain widely used in automotive, industrial, and energy storage applications due to their reliability and cost-effectiveness. The performance of these batteries largely depends on the quality of materials used in the negative plate, especially the expander system.
As demand increases for longer cycle life and better low-temperature performance, high-quality lignin-based expanders play a crucial role in optimizing battery efficiency and durability.
