Technology
Lithium iron phosphate uses no nickel and no cobalt, tolerates abuse better than any alternative in wide use, and lasts for thousands of cycles. It stores less energy per kilogram than the nickel-based alternatives — and for most vehicles and nearly all grid storage, that has turned out to be an acceptable trade.
In one sentence
LFP is a lithium-ion cathode chemistry using iron and phosphate rather than nickel and cobalt, offering lower cost, higher thermal stability and longer cycle life at lower energy density.
The materials are the argument. Iron and phosphate are abundant and cheap, with none of the supply concentration or the ethical and price exposure that cobalt carries. That alone makes the cathode substantially cheaper per unit of energy stored than nickel-rich alternatives.
The chemistry is also intrinsically more stable. Its crystal structure holds oxygen more tightly, so a cell that overheats is far less likely to enter a self-sustaining runaway. Combined with cycle lives measured in thousands rather than hundreds of cycles, that makes it the default for stationary storage and for standard-range vehicles.
Roughly a fifth to a third less energy per kilogram at cell level than nickel-rich chemistries. In a vehicle that means a heavier pack for the same range, or less range for the same weight. Pack-level engineering has narrowed the gap — a chemistry safe enough to pack more densely loses less at pack level than at cell level — but the underlying difference remains.
LFP holds a nearly constant voltage across most of its charge range, which is good for the application and awkward for the battery management system, because voltage is the usual way to infer remaining charge. Manufacturers compensate with modelling and by periodically charging to full to recalibrate — which is why LFP vehicles are often told to charge to one hundred percent regularly, and nickel-based ones are not.
The chemistry's ionic conductivity falls more sharply at low temperature, so cold-weather charging and power are weaker unless the pack is pre-heated. This is a real limitation, addressed by thermal management rather than eliminated, and it is one reason nickel-based chemistries retain a place in premium and cold-market vehicles.
2 of these are marked as a chokepoint: a handful of qualified suppliers, a multi-year lead time, or a single geography.
The one expensive material it cannot avoid; the rest of the cathode is abundant.
LithiumProducing battery-grade iron phosphate at scale is concentrated in a small number of countries.
Cathode materialsThe flat voltage curve makes state-of-charge estimation harder and pushes the difficulty into software.

What each company supplies at this step, and — where a public figure exists — its share of this specific market — with what that share measures, the period it covers and who published it. Some rows also show the company’s own reported revenue for the segment covering this step, which is a different thing: it says how much this business matters to that company, not how much of the market it holds. Not a ranking and not a recommendation.

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.
