WHAT IS A LAB-SCALE POUCH CELL LINE?
A lab-scale pouch cell production line is a compact system designed for the research and development of lithium-ion, sodium-ion, solid-state, and next-generation batteries.
Equipment configurations can be customized based on research requirements and budget.
ASSEMBLY FLOW CHART OF POUCH CELL
KEY PROCESS
It typically covers three main stages: raw material preparation, electrode preparation, and cell assembly, providing a complete workflow for laboratory-scale battery prototyping and testing.
This end-to-end workflow ensures traceability and repeatability, critical for scaling up battery technologies from lab prototypes to commercial production.
