One integrated line from powder to packed cell

Cathode, anode, binder and conductive additives are dosed by weight and blended under vacuum for a homogeneous slurry.

Electrode slurry is coated to a controlled density, with automatic on-line side-thickness measurement and full-width defect inspection.

Electrodes are slitted and die-cut into strips with tight dimensional tolerance and a clean, burr-free edge.

Automated washing removes residual metal particles and surface contaminants that could otherwise initiate an internal short.

Jelly rolls are wound on semi-automatic and integrated winding machines, with X-ray inspection confirming alignment on every roll.

Heat-shrink film is sleeved over the cell body, providing insulation and mechanical protection for the finished pack.

Cells are vacuum baked to remove residual moisture before electrolyte filling, preventing gas generation and internal corrosion.

Electrolyte is injected by segmented filling machine with on-line volume verification for every cell.

Terminals are welded, caps fitted and the cell sealed hermetically, with automated tab welding and double-station integration.

The finished cell body is inserted into the steel case at a controlled rate to protect the winding from deformation.

OCV, capacity, voltage and internal resistance are graded automatically so that cells can be matched within a pack.
