Cell manufacturing capacity, plant by plant.
CURATED INDEX◊ confidence: Medium
// the signal · what the data says
China (led by CATL and BYD) controls the majority of global cell capacity; the US and EU are racing to localize via IRA and EU incentives. Announced GWh far exceeds what will actually ramp — utilization and yield, not nameplate, decide real output.
