Is NMP still available given the REACH restriction?

Yes — it remains available under REACH worker-exposure controls (and US EPA TSCA limits on some uses). It must be handled in closed systems with PPE.

What makes battery grade different from technical grade?

Battery grade needs very low water and metals and ≥99.9% purity for Li-ion electrode slurries.

How is it handled safely?

As a Repr. 1B substance: closed systems, ventilation, appropriate PPE and no skin contact. Reference the SDS.
