CATL Now Supplies Around 40% of the World's EV Batteries

The global market for batteries fitted to electric and hybrid cars grew 20% in the first half of 2026, and CATL captured a disproportionate share of that growth. The Chinese manufacturer now supplies around 40% of every EV battery installed worldwide, up from an already dominant position a year ago.

Add BYD, which supplies its own cars and increasingly other people's, and two Chinese companies account for more than half the global EV battery market between them.

The concentration, in one table

The "everyone else" column is what makes the picture unusual. It is not that CATL leads a field of close competitors — it is that CATL alone is roughly three times the size of the second-placed supplier, and the remaining share is split among LG Energy Solution, SK On, Samsung SDI, Panasonic and a long tail of smaller manufacturers.

Growth is not the same as demand recovery everywhere

A 20% expansion in installed battery capacity is a healthy number, but it is not evenly sourced. Chinese domestic demand and exports drive most of it, alongside a European market that has been running well — European BEV share reached 25.6% in June with H1 registrations past 1.6 million.

The capacity being installed to serve that European demand is overwhelmingly not European. Deloitte's recent assessment found that Asian manufacturers control 98% of Europe's battery cell capacity — including the cells produced inside Europe, which are largely made in Asian-owned plants on European soil.

Why this matters for European buyers

Three practical consequences follow from a market this concentrated.

Pricing power. When one supplier holds 40% of a market, its cost curve sets the floor for everyone's battery pack. CATL's LFP cells are the reason entry-level EVs across Europe have been getting cheaper faster than anyone forecast — and the reason that trend can reverse if CATL's margins come under pressure.

Chemistry direction. CATL decides which chemistries scale. Its sodium-ion and fast-charging LFP roadmaps effectively become the industry's, because no other supplier has the volume to make an alternative cheap. A European carmaker choosing a different chemistry pays a premium for the privilege.

Exposure. Any disruption to CATL — regulatory, geopolitical or industrial — propagates directly into European vehicle production. This is the concern behind the EU's €1.5 billion Battery Booster programme and China's recent move to set a national standard for battery health disclosure, which will effectively become the global reference before Europe's own arrives in 2027.

The direction of travel

Europe's battery independence plans are real and funded, but they operate on a timescale measured in plant construction, not quarters. On current H1 2026 numbers, the gap between where European cell capacity is and where policy wants it to be widened rather than narrowed.

For a buyer choosing a car this year, none of this is visible from the driver's seat. The cell in a European-built EV is very likely Chinese in origin or Chinese in design, it is probably good, and it is cheaper than a European equivalent would be. That is the trade that has been made.
