If the smartphone's chain spreads its chokepoints across four countries, the electric car's battery does the opposite: its minerals are dug on four continents, but they funnel through one country to be refined and turned into cells. Chinese firms make about two-thirds of the world's EV batteries — and roughly one in three new electric cars, anywhere, runs on a cell from a single company.
An electric car is, in cost and weight, mostly its battery — and the battery's supply chain behaves nothing like the phone's. Where the phone leans on a handful of irreplaceable national specialists, the battery funnels through a single country. The metals are mined on four continents, but they are refined and turned into cells overwhelmingly in China: Chinese firms make on the order of two-thirds of the world's EV batteries, and roughly one in three new electric cars anywhere runs on a cell from one company — CATL.
It starts as a basket of metals from the remotest corners of the planet. Lithium — Australia's hard rock and the brine lakes of Chile's Atacama. Cobalt — about three-quarters of it from the Democratic Republic of the Congo. Nickel — increasingly from Indonesia, now the dominant source. Graphite for the anode — mostly China, with Mozambique and Madagascar. Plus manganese, copper and more. No single country has all of it; the map of where a battery begins is genuinely global.
Here is the real chokepoint — and it is not the mine. Wherever the ore comes out of the ground, it mostly travels to China to be refined into battery-grade chemicals: around seventy percent of the world's refined lithium, most of its cobalt, and the lion's share of its graphite. This is the quiet monopoly the headlines miss. A country can dig its own lithium and still be unable to use it, because the step that turns rock into a usable cathode happens, overwhelmingly, in one place.
The refined chemicals become cells, and here the concentration is starker still. CATL — named after Ningde, a once-poor city in Fujian it has turned into an industrial powerhouse — makes around 38% of the world's EV batteries, more than double its nearest rival, and supplies Tesla, BMW, Volkswagen, Ford and nearly every Chinese brand; BYD is a close second. The cells go into packs and into cars, most of them assembled in China — still, by a wide margin, the world's EV factory.
From there the batteries flow outward, and the politics begin. To get inside the European Union's 38% tariff on Chinese EVs, CATL is planting gigafactories across Europe — Germany (running and already profitable since 2022), Hungary (a multi-billion-euro megaplant), Spain (with Stellantis). The United States is going the other way — tariffs, a Pentagon blacklist, forced-labour scrutiny — and yet analysts judge it "years behind," with Ford already licensing CATL's technology. Set against the atlas, the EV battery is the mirror image of the phone: not many national chokepoints but one — China's midstream — that the whole world's electric transition has to run through.
