Start with an application and work backwards to the material, the specification and the qualification requirements.
Lithium, graphite, nickel, cobalt and manganese can appear in different battery chemistries. Not every chemistry uses every material.
Questions to resolve
Chemistry choice; cathode/anode specification; cycle life; safety; qualified supplier lead time.
Copper supports electrical equipment and conductors; engineering requirements determine where alternatives are appropriate.
Questions to resolve
Conductor performance; equipment design; grid delivery schedules; embodied material requirements.
Selected rare-earth elements are used in permanent magnets for high-performance motors and other applications.
Questions to resolve
Magnet grade; temperature performance; separation and alloy route; magnet manufacturing capacity.
Gallium and germanium have specialist roles in semiconductor and optical applications. Product form and purity matter.
Questions to resolve
Device-specific grade; substrate or precursor route; qualification; export-control checks for the actual transaction.
Tungsten and other specialist inputs contribute hardness, wear resistance and temperature performance.
Questions to resolve
Carbide or metal product form; tool performance; regrinding and scrap recovery options.
Antimony and manganese have uses across alloys, chemicals and other industrial products. Uses depend on the material form.
Questions to resolve
Substance identity; product specification; applicable controls; end-of-life handling.

Location alone does not establish responsible sourcing, compliance, qualification or continuity of supply.
Investigate the legal entity, ownership, chain of custody, material specification, environmental and social evidence, sanctions and export rules, logistics, and contract terms for the actual purchase.
