BLA Series

The BLA Series is a flexible platform for laminating and stacking mono- and bi-cells in the production of pouch cells or prismatic cells (roll-to-cell). Due to its modular design, it is freely configurable and can be used for both, as a pilot line and for mass production.

FEATURES

Several independent modules are combined to perform the individual process steps, such as

  • Unwinding of pre-notched electrode rolls and separator material with highly precise tension control
  • On-the-fly cutting of the electrodes and placing between the separator
  • Heat and press lamination for a mechanically stable connection of electrodes and separators
  • On-the-fly cutting of laminated cells
  • Integrated optical and electrical testing as well as immediate sorting out of bad parts
  • High-precision stacking into a workpiece carrier

The materials are covered by a belt protector to avoid contamination by particles or sticking of the separator onto the laminating unit. Web alignment units increase the cell capacity through optimal utilization of the active material.

ADVANTAGES

  • Increased productivity through one of the fastest cell assembly processes
    • Simultaneous processing of four layers of material
    • With up to 400 mm/s material speed at least twice as fast as any other alternative stacking machine
    • Very high and stable process performance
  • Unproblematic change of product size or configurations (axial/radial) possible thanks to the high flexibility of the production line
  • High quality and safety of the cells
    • Avoidance of short circuits in peripheral areas of cells, since the separator of the laminated cells during battery operation shrinks to a lesser extent than in non-laminated cells
    • Full traceability of the cells
    • Minimal rejects in follow-up processes thanks to a quick analysis of defects in an integrated reject station
