About the usage of NMP in the lithium-ion battery industry and the REACH regulation.
The usage of NMP is KEY for the European battery industry’s competitiveness and future development, especially in the context of the “Battery Alliance” where the European Commission would like to encourage the manufacturing of Li-ion electrodes and cells in Europe.
Although the protections measures that can be taken in the REACH restriction process, have been recognized suitable, the ECHA (European Chemical Agency) has in addition prioritized NMP for inclusion in the REACH authorization process (annex XIV).
Key recommendation: Do not include NMP on REACH Annex XIV for authorization.
✓ All potential risks are already addressed by the restriction, which is the most appropriate risk
reduction measure for NMP.
✓ No alternatives are available today for the battery industry use in the positive electrodes, as stated
in the table C.01 of the background document to RAC/SEAC opinions on NMP (25 Nov 2014).
✓ An alternative to NMP for lithium batteries graphite negative electrodes was found 20 years ago,
but even this alternative still needs NMP for the manufacturing of the alternative binder.
