CAM Production: As frontrunners in producing pure and mixed oxides through spray roasting pyrohydrolysis, ANDIRZT Schuler provides market-leading equipment for making Cobalt-oxide and mixed NMC/NCA-oxides - essential active materials in lithium-ion battery (LIB) cathodes.

Our approach features spray pyrolysis of mixed metal chloride and nitrate solutions, delivering a cost-effective and environmentally friendly method for producing LIB cathode precursor material.

Over the years, we’ve designed, built, and operated a total of six cobalt-oxide plants, four of which are currently in operation. Our solution is now primed and ready for the market.

From improving current battery technologies to exploring new possibilities in LIB production, our lithium battery equipment and processes are reliable and efficient. Trust us to power the next generation of LIB cathode materials.

Elecrode Manufacturing

Calendering: ANDRITZ has developed a new calendering concept to overcome the current process limitations. The new calender offers an even load distribution at the calender nip resulting in very good thickness evenness in the product at a width of up to 2,000 mm. This can be achieved through adding an axial roll displacement. Both rolls are ground to get a special Double-S-shape, which influences the quarter points of the W-shaped profile, created by the roll bending and crowned grinding.
