Access to battery terminals?
Does the proposed solution need to address discharge of batteries where the terminals are damaged, corroded, or otherwise inaccessible, or is the scope limited to batteries with intact and accessible terminal connections?

Oxalate/formate-based mineral recovery chemistry within scope for 26-PH1?
For topic 26-PH1, would a chemical process focused on improving recovery of rare earth / critical minerals from end-of-life lithium-ion battery materials be considered responsive if it uses low-carbon oxalate/formate-based precipitation chemistry?
Specifically, we are considering a Phase I concept to demonstrate selective precipitation/recovery of representative critical minerals from battery-recycling streams, benchmarked against conventional oxalic acid/oxalate routes, with attention to safer handling and improved recovery economics.
Or is this topic primarily focused on residual-energy removal / battery de-energizing technologies rather than downstream mineral recovery chemistry?
