Who makes your battery? The cell map behind the electric market

Asked where their car comes from, buyers answer with the marque: German, Japanese, Korean, Chinese. That answer was accurate ten years ago. Today, with the battery the costliest component of an electric car and the greatest single determinant of how it drives, the sharper question is: who made the cell?

And the answer is strikingly concentrated. Three companies make more than two-thirds of the world’s cells, two of them Chinese. That concentration is higher than anything seen in an automotive supply chain for decades, and it is redistributing power in the industry in ways the market has not yet absorbed.

In practice this means a European or Japanese marque may sell a car whose cells are entirely Chinese, and that competition in the Gulf market sometimes runs between two cars sharing a supplier. A buyer choosing to avoid a particular country of origin may find they have bought it inside the box.

The Gulf, by virtue of its climate alone, is an ideal market for the chemistry that became the world’s cheapest. Such coincidences are rare.

The cell is not a single component but a chain. It starts with lithium, nickel, cobalt, phosphate and graphite, and passes through chemical processing — the most concentrated link of all, since the share of cathode and anode material processed in China far exceeds its share of mining. Then the cell is made, assembled into modules, and packed with thermal and electronic management.

The cost of that chain is what changed the market. Pack cost has fallen to less than half its level eight years ago, and that decline — not government subsidy, not consumer enthusiasm — is what made the electric car competitively priceable.

The one break in the curve came in 2022, caused by a jump in lithium and nickel prices rather than any technology setback. That point deserves attention: the battery chain is far more exposed to raw-material price shocks than a petrol-engine chain, which makes electric pricing less stable over the medium term.

The second shift in this chain is chemical. Lithium iron phosphate — LFP — displaced nickel manganese cobalt from the top of the market within a few years. The reason is cost before engineering: no nickel and no cobalt in the recipe, and therefore no exposure to the two most expensive and volatile metals.

What does that mean for the Gulf buyer specifically? Two contradictory things. LFP chemistry gives longer cycle life and better thermal safety — both of which matter in a climate that passes fifty degrees. It also loses a tangible share of its range when temperatures fall, a drawback that is barely relevant in the Gulf and decisive in northern Europe.

Which is to say that the Gulf, by virtue of its climate alone, is an ideal market for the chemistry that has become the world’s cheapest. That is a coincidence in the Gulf buyer’s favour, and they do not come often.

But heat cuts both ways. A battery tolerates ambient heat reasonably well and suffers from the internal heat generated by repeated fast charging in hot weather. The standard worth asking about in the Gulf is therefore not battery capacity but cooling-system quality: effective liquid cooling, or economical air cooling? The difference shows up in year three, not on a test drive.

And a third question that gets overlooked: what does the battery warranty actually cover? Most warranties run eight years or a set distance, conditional on capacity not falling below seventy per cent. That condition is the substance of the warranty: a battery down to seventy-five per cent after four years is not covered, and is at the same time plainly a weak battery.

The effect of this map on the Gulf market is direct. A marque that owns a cell plant — or holds a long-term contract at a fixed price — can price aggressively and sustain it. A marque buying cells on the open market sees its costs swing with every move in lithium and may have to raise a price months after setting it.

Reading electric price announcements in the region therefore needs one extra question: is this a price built on secured cost, or an entry price that will be revised? The difference usually becomes visible in year two.

And one file remains open: what happens to the battery after the car? The region has no recycling or second-life system at any meaningful scale, and the first wave of batteries leaving service will arrive within a few years. That is a regulatory and industrial question at once, and whoever builds for it early turns a liability into a resource.

Gulf Auto will track the cell map annually, and long-term supply contracts in particular: they are the truest indicator of who will be able to hold their prices in this region and who will not.
