Manz launches BLA platform for lithium-ion cell production

Manz has developed a production platform called the BLA series. It is aimed at makers of lithium-ion batteries. The system handles laminating and stacking of hard case and pouch cells.

Modules can be combined for different process steps. Manz lists unwinding pre-scored anode and cathode roll material, cutting electrodes, placing them between separator, heat and press lamination, testing, and stacking on a workpiece carrier. The platform is freely configurable and can serve as a pilot system or in automated mass production. Mono or bi-cells can be made in axial and radial configurations.

In the BLA process, Manz says, anode and cathode are placed from above and below onto a centered separator rather than folding the separator in a Z-shape. The resulting cell is laminated, cut and stacked. Manz states the process is currently unique on the market and that cells made this way are significantly safer than non-laminated cells, especially against voltage flashovers. Manz cites a material speed of up to four hundred millimetres per second, at least twice as fast as alternative stacking systems, plus integrated optical and electrical tests that eject defective material.

For equipment buyers, ask whether your cell format and mono or bi-cell design fit the BLA module set. Request evidence for the safety and speed claims under your own materials. Clarify which test steps are integrated and how rejected material is handled.
