SG-100L Manual Roller Press Machine

The SG-100L is a compact, bench-top manual roller press designed for laboratory calendering of battery electrodes and soft metal foils. It applies controlled compressive force through precision rollers to reduce electrode thickness, improve particle-to-particle contact, and increase electrode density after coating and drying—key steps for improving conductivity, mechanical integrity, and reproducibility in electrochemical testing.

Principle of operation

Electrode sheets (typically coated Al or Cu current collectors) are fed through dual rollers. The roller gap is adjusted to a target thickness, producing uniform compaction across the electrode width. This calendering step helps reduce porosity, improve adhesion to the current collector, and minimise thickness variation that can influence capacity, impedance, and cycle-to-cycle stability.
