How China Became the World Leader in Electric Car Batteries
By Iulita Onica | November 13, 2025
Twenty years ago, China had just two electric vehicle (EV) battery manufacturers.
Today, it produces over 75% of all lithium-ion cells in the world, becoming the undisputed leader of the technology powering the future of transportation.
From Olympic Buses to Global Dominance
It all began at the 2008 Beijing Olympics, where athletes and officials were transported by electric buses powered by Chinese-made lithium-ion batteries.
That project was China’s first major step toward an energy revolution.
In 2006, the government made “new energy vehicles” a national priority and soon invested billions in research, battery production, and charging infrastructure.
State Support and a Massive Market
The secret to China’s success lies in strong government backing and a huge domestic market shielded from foreign competition.
The government offered large subsidies to EV buyers and required automakers to use Chinese-made batteries in order to qualify for these benefits.
This move propelled CATL and BYD to global fame, allowing them to overtake Japanese and South Korean giants and become the top battery makers in the world.
Why Chinese Batteries Are So Competitive
China’s battery advantage isn’t just about low prices.
It’s also about efficiency, scale, and full control of the supply chain — from raw materials to finished products.
“China can produce more, faster, and cheaper without compromising quality,” says a RealLi Research analyst.
CATL now accounts for nearly 40% of the world’s EV battery output, far ahead of its closest rivals.
How the West Fell Behind
While the U.S. and Japan pioneered lithium-ion technology, they missed the industrial opportunity.
After the 2008 financial crisis, many American clean-energy startups went bankrupt or were bought by Chinese companies.
Meanwhile, Beijing invested heavily and never stopped building.
Today, 85% of global battery production capacity is in China, compared with only 5% in North America and 7% in Europe.
Innovation and Education
China also focused on developing technical talent.
It created specialized university programs and vocational schools to train thousands of battery engineers.
Companies like CATL and BYD employ tens of thousands of engineers constantly improving performance and safety.
In 2020, BYD introduced its famous “blade battery”, a safer and cheaper lithium-iron-phosphate design that reshaped the global industry.
Can Anyone Catch Up?
Experts say it’s unlikely any country will catch up within the next decade.
“They’re just so much further ahead,” says Taylor Ogan, CEO of Snow Bull Capital in Shenzhen.
Still, emerging solid-state batteries could open new opportunities for the U.S., Japan, or South Korea — but for now, China remains firmly in the lead.
From a handful of buses in Beijing to powering millions of cars worldwide, China’s journey to the top of the EV battery world is a story of vision, strategy, and unrelenting ambition.
