Dürr Systems and LiCAP Technologies are working together to revolutionise the production of battery cells, traditionally reliant on wet coating, with the sustainable Activated Dry Electrode technology.

The partnership now includes Cellforce Group, a subsidiary of Porsche.

The companies are focused on integrating LiCAP’s Activated Dry Electrode technology into Cellforce’s battery production line. Combined with Dürr’s expertise in electrode coating, this marks a significant step towards an innovative approach to industrial-scale dry electrode coatings.

The new technology improves battery performance while minimising environmental impact. By eliminating toxic solvents and energy-intensive drying ovens, it reduces energy consumption, shortens process times and reduces CO2 emissions by roughly 1 t per 10 kWh of electrode capacity produced, the companies say.

Cellforce recently licensed the technology and Dürr has commissioned a gigawatt-scale proof-of-concept cathode line in Chassieu, France.

“By collaborating with LiCAP, Dürr is broadening its dry coating solutions to support customers like Cellforce in adopting this innovative, dry electrode production process,” said Bernhard Bruhn, vice-president, global business LIB at Dürr Systems.
