FREYR is developing two business concepts, based on the licensing-in and joint venture partners models. FREYR puts sustainability at the core of both concepts.
The 24M production process (licensed) is a novel and simplified battery cell production process. The process is solvent and binder free, reducing use of environmentally hazardous materials and substantially improving recycling potential.
Simplified process reduces equipment, space and energy requirements
24M has drastically reduced the steps in the battery cell manufacturing process compared to conventional technology, enabling a more compact production line without large equipment items such as coater, mixer, NMP and NMP recovery, slitting and press. No heating and drying are needed, greatly reducing energy consumption, and the electrode process is emission free, thereby reducing the facilities’ direct CO₂ emissions.
Reduced material consumption
The 24M process enables thicker electrodes which require less inactive materials (copper, aluminum and separator), thereby reducing emissions from production and transportation of these materials. There is no need for binder and NMP solvent which usually is a factor of high environmental concern.
A battery without binder enables direct recycling which is less energy and chemical intensive. The recycled active materials can be re-used directly in the production process with a simplified refinement, which enables on-site recycling in Mo. This enables increased recycling with lower related emissions compared to conventional facilities.
Other Technologies – Conventional + New technologies
FREYR facilities may use conventional technologies, but then in combination with new processes to improve energy efficiency and reduce environmental impact in battery cell production.
Multiple promising technologies are available that may substantially reduce the footprint of conventional battery technologies, and FREYR is assessing the maturity and implications of implementing these in a giga-factory in Mo i Rana.
