The usage of NMP is key for the European battery industry’s competitiveness and future development.
The proposal for inclusion in Annex XIV contradicts the opinion given by RAC (Risk Assessment Committee) and SEAC (Socio-Economic Assessment Committee) from ECHA in November 2014 to the EU Commission to opt for restriction for NMP as the best risk management option.
Lithium batteries do not contain NMP. But high performance products are based on the usage of this solvent, totally removed during the manufacturing process: most lithium-ion batteries manufacturing processes are using NMP as a solvent of the electrodes binder , due to stringent solvation and dry atmosphere requirements. The NMP used as a solvent is essentially collected after the drying process, reused for cleaning of equipment and finally sent for proper recycling.
