Battery materials: mines, refineries and where they actually are
Battery supply chains are usually described in terms of where the minerals are mined. The more useful question is where they are refined into battery-grade materials, because that step is far more concentrated than mining and it is the one that cannot be replaced quickly.
In one sentence
Battery materials are the mined and refined inputs to cell manufacturing — lithium, nickel, cobalt, graphite and their processed compounds — together with the recycling streams that return them.
Mining is geographically diverse for most battery inputs. Refining is not. Converting ore or brine into a compound pure enough for a cell is a chemical process that has concentrated heavily in a small number of countries, and it is the step that determines whether a cell can be made.
That distinction explains most of the policy activity in this area. Opening a mine takes years; building a qualified refinery takes years and requires process knowledge that is not widely held; and a cell manufacturer cannot switch material supplier without re-qualifying the cell, which takes many months more.
Recycling matters for the same reason. A recycled stream that produces battery-grade material displaces refining capacity, not just mining — which is where its strategic value lies, over and above the environmental case.
How this breaks down
Split by material, because each has a different geography and a different constraint.

What this depends on
Technology dependencies are solved by engineering; supply dependencies are solved by building something, which takes years.

Qualification by cell manufacturers
Materials are qualified into a specific cell design; a new source is a months-long validation, not a purchase order.

Companies across Battery materials

How these pages are written
Each page explains one technology in plain language, states what it depends on, and names companies by what they supply at that step. Company roles are described qualitatively and deliberately carry no market shares, revenue figures or rankings — those change faster than an explainer can, and a stale number is worse than none. Ticker links point at company pages on this site and are provided for reference only.
Nothing here is investment advice, a recommendation, or a forecast. A company named on a page about a technology is not thereby a good investment, and the chokepoints described are structural facts about supply chains rather than predictions about prices. Technology moves; where a page describes something as unresolved or in development, that was true when it was written.
