The set on Halo divides into three steps of one chain. Five entries recover a critical metal from waste, seawater or a side stream, six work on the electrode and electrolyte chemistry, and five on the can that holds it. Almost nothing addresses primary mining. On Halo it spans four groups, including recovering the metal, electrode and electrolyte chemistry, and cells and casings.
Stage of development. Work on critical minerals & battery materials on Halo is split between university programs and companies. 25% of the solutions are in market. Montana State University has the most, followed by University of Alberta. Licensing and sponsored research are the usual partnering routes, and about 24% of the solutions that state terms offer pilot engagements.
Three trends in critical minerals and battery materials on Halo
Recovery, not extraction. Five entries source a critical metal and not one of them mines it. Mining waste reprocessed modularly, trace elements pulled from seawater, pectin side streams used for selective metal recovery, end-of-life tires giving back zinc and silica, and a manganese oxide surface engineered for lithium extraction. The deposit everyone is working is one somebody already dug.
Aluminum is the casing answer. Five entries stop at the can, and four of the five make it from aluminum: high energy domestic cells in an aluminum can, prototype 21700s in an aluminum case, an alloy casing argued on EV charge and discharge performance, and custom cylindrical cells fabricated to order. The fifth treats the case purely as a forming problem.
The chain shows up in three pieces. Recover the metal, make the electrode, build the can. Five entries at each step and almost no overlap between them, with the casing group answering the same aluminum question that runs through energy storage. No organization in the set is doing more than one of the three.

Frequently asked questions
What are critical minerals and battery materials?
Critical minerals and battery materials covers sourcing the elements a battery needs and turning them into a cell. It spans recovery of metals from mining waste, seawater, side streams and end-of-life products, the anode and electrolyte chemistry those metals go into, and the casings and cell formats built around them. Battery manufacturers, mining companies and recyclers are the buyers.
