CATL makes the giant rechargeable batteries that power electric cars and stores electricity for power grids.
CATL is the world's largest maker of electric-car batteries. If you drive an electric vehicle made by a big automaker, there is a decent chance the battery pack under the floor came from this Chinese company. It also builds massive battery systems that electric utilities use to store power, plus a smaller business selling batteries for things like scooters and power tools.
The core business is straightforward. Carmakers design a vehicle, then hand CATL a list of requirements: how much range, how fast it should charge, how much space it can spare, and what price works. CATL engineers a battery pack to fit, builds it in enormous factories, and ships it to the car plant. Its customers are basically the entire auto industry — Tesla, BMW, Volkswagen, Ford, Hyundai, and many Chinese brands including BYD, which builds its own batteries too and is CATL's fiercest rival. Carmakers choose CATL because batteries are the single most expensive part of an electric car, and CATL has spent years and billions of dollars learning to make them cheaper, safer, and longer-lasting than almost anyone else. The story of how it got there is worth knowing. The company was founded in 2011 by Robin Zeng, a physicist by training, who spun it out of a prior battery business that made cells for consumer electronics. China's government then poured support into electric vehicles, and CATL rode that wave to become the dominant supplier, eventually listing on the Shenzhen exchange in 2018. Today it spends heavily on research — thousands of engineers working on new battery chemistries — and it has pushed into a sodium-ion battery and a fast-charging "Shenxing" line, bets aimed at making electric cars cheaper and more convenient. The cash it generates mostly goes back into building more factories, including plants in Germany and Hungary to serve European carmakers and sidestep trade tensions.
The vulnerability is real. Battery making is capital-hungry, and the industry has been drowning in overcapacity, which pushes prices down and squeezes margins. CATL also faces rising political risk: the United States has moved to restrict Chinese battery components from electric vehicles that qualify for tax credits, and Europe is weighing similar rules. And because so much of its fate is tied to a handful of giant automakers, a slowdown in electric-car demand hits it directly. Still, its scale, engineering depth, and grip on the supply chain give it a moat most rivals cannot match — which is why it remains the company the rest of the battery world is measured against.
