Product Overview
LB-5 is a sodium lignosulfonate battery expander made from purified kraft pine lignin and an alternative to the Borregaard Vanisperse series. As the organic expander in the negative plate of lead-acid batteries, it delivers reliable cold starts at −10 °C to −18 °C, longer cycle life and low self-discharge.
Challenges in Lead-Acid Batteries
- Reduced battery capacity over time
- Poor cold-start performance in low temperatures
- High self-discharge rates
- Short cycle life
How LB-5 Solves These Problems
- Alternative to the Borregaard Vanisperse series, with better value
- Improves battery capacity and stability
- Reliable cold starts at −10 °C to −18 °C
- Low-impurity formulation reduces self-discharge
- Extends cycle life
Key Benefits
- Vanisperse Alternative
Replaces the Borregaard Vanisperse series - Cold-Start Performance
Reliable starts at −10 °C to −18 °C - Longer Cycle Life
Less degradation over repeated cycles - Ultra-Low Impurity
Low self-discharge, stable performance
Applications
- Automotive SLI batteries
- Motive power batteries (forklifts, traction)
- Energy storage systems (ESS)
- Industrial batteries
