The country is not only a major producer of electric vehicles. It also has a powerful position in batteries, battery materials, critical mineral processing, components, manufacturing equipment, and the supply networks that connect these industries together.
According to the International Energy Agency (IEA), China accounted for 70% of global electric car production in 2025 and more than 80% of global battery cell production. China also produced around 85% of cathode active materials and more than 90% of anode active materials used in electric car batteries.
So how did China become so dominant?
The answer is not simply cheap labor or government support. China's position has developed through a combination of massive domestic demand, industrial scale, supply-chain integration, manufacturing expertise, infrastructure, investment, and intense competition.
China Built More Than an EV Industry
One of the biggest reasons China has an advantage is that its EV industry did not develop in isolation.
Electric cars require many different industries to work together.
A typical EV supply chain can include:
- Mining and processing of lithium, nickel, cobalt, graphite, and other materials
- Chemical processing
- Cathode and anode production
- Battery cell manufacturing
- Battery pack assembly
- Electric motors
- Power electronics
- Charging equipment
- Automotive components
- Vehicle assembly
- Logistics and recycling
China has developed significant capabilities across many of these stages.
This creates an integrated industrial ecosystem in which manufacturers can source components and materials from companies located relatively close to their factories.
That integration can reduce transportation costs, shorten development cycles, and make it easier for companies to scale production.
China Has Massive Battery Manufacturing Capacity
Batteries are arguably the most important part of the modern EV supply chain.
In 2025, China accounted for more than 80% of global battery cell production, according to the IEA. Chinese battery manufacturers also supplied almost 75% of the batteries deployed in electric cars globally that year.
This scale matters.
Large production volumes allow manufacturers to spread fixed costs across millions of battery cells. Suppliers can also invest heavily in specialized equipment, factories, research, and quality-control systems because they have access to a huge market.
China's battery industry has therefore benefited from a reinforcing cycle:
More production → more experience → lower costs → stronger demand → even more production.
This is one reason battery manufacturing has become difficult for new competitors to replicate quickly.
China Controls Important Battery Components
Battery cells are only one part of the supply chain.
Before a battery cell can be manufactured, several materials and components must be produced to very precise specifications.
Two of the most important are cathode and anode active materials.
China has an especially strong position in both.
The IEA estimates that in 2025 China produced approximately 85% of global cathode active material and more than 90% of anode active material for electric car batteries.
This is important because a country can build battery factories relatively quickly, but producing battery-grade materials at large scale requires specialized technology, equipment, suppliers, chemical processing capabilities, and manufacturing experience.
That makes this part of the supply chain harder to replace.
China Is Particularly Strong in LFP Batteries
Another major advantage is China's leadership in lithium iron phosphate, commonly known as LFP batteries.
LFP batteries have become increasingly popular because they generally offer lower material costs and good durability, although they have different energy-density characteristics compared with nickel-based chemistries.
The IEA reported that LFP batteries represented nearly half of the global EV battery market in 2024. China was particularly dominant, with LFP accounting for nearly three-quarters of its domestic EV battery demand that year.
China's position in LFP is even more concentrated upstream.
The IEA estimates that more than 98% of LFP cathode material and LFP battery cells were produced in China in 2024.
This gives Chinese manufacturers a significant advantage as automakers around the world increasingly look for lower-cost battery technologies.
Critical Mineral Processing Is Another Advantage
China does not need to mine every mineral used in an EV to control an important part of the supply chain.
Processing and refining are just as important.
Lithium, cobalt, graphite, nickel, manganese, and other materials need to be processed into high-purity forms before they can be used in advanced battery manufacturing.
The IEA says China remains the dominant refined supplier for almost all major battery minerals. In 2024, China was responsible for around 65% of global lithium refining, 75% of cobalt refining, and more than 90% of graphite refining, based on the mineral supply-chain data reported by the agency.
This creates an important distinction:
Mining a mineral and processing it into a battery-grade material are two different things.
A country may have large mineral deposits but still depend on overseas processing capacity.
China invested heavily in the processing stage, giving its battery and EV manufacturers access to a large domestic network of refined materials.
China Does Not Mine Everything It Uses
China's dominance should not be confused with complete control of global mineral resources.
Many important minerals come from other countries.
For example, Australia, Chile, and China together accounted for about 85% of global lithium mining in 2023. Indonesia was responsible for more than half of global nickel mining, while the Democratic Republic of Congo accounted for almost two-thirds of cobalt mining.
The important advantage is that China has built extensive processing and manufacturing capabilities around these materials.
This allows Chinese companies to participate in the supply chain even when the original mineral is mined somewhere else.
A Huge Domestic EV Market Helped Create Economies of Scale
China also has something that many other countries do not have: a massive domestic EV market.
A large local market gives manufacturers an opportunity to produce at enormous scale before expanding internationally.
This creates several advantages.
Factories can operate at high volumes. Suppliers can develop specialized components. Automakers can collect large amounts of real-world data. Battery companies can test and improve new technologies. Charging networks can expand alongside vehicle sales.
The result is a large industrial ecosystem that continuously feeds itself.
The IEA estimates that China produced about 70% of all electric cars globally in 2025.
That scale gives Chinese manufacturers a substantial manufacturing base from which to compete in international markets.
Intense Competition Has Pushed Costs Down
Another factor that is sometimes overlooked is competition.
China's EV market has become extremely competitive, with automakers competing on price, range, battery technology, software, charging performance, and features.
Battery manufacturers have faced similar pressure.
The IEA reported that global lithium-ion battery pack prices fell by 20% in 2024, while battery prices in China declined by nearly 30%. The agency linked China's faster cost reduction partly to intense competition, manufacturing efficiency, higher yields, supply-chain integration, and a large skilled workforce.
Competition can be painful for manufacturers because it puts pressure on profit margins.
But it can also accelerate innovation.
Companies have strong incentives to reduce waste, improve production efficiency, redesign components, and bring new technologies to market faster.
Manufacturing Equipment Matters Too
The supply chain doesn't stop with raw materials and factories.
Battery manufacturers need specialized production equipment to manufacture cells and battery materials.
China, Japan, and South Korea are major players in battery manufacturing equipment, with China having developed a particularly large domestic ecosystem.
This creates another layer of industrial integration.
When battery manufacturers can source equipment, materials, components, engineering services, and skilled workers from a mature domestic ecosystem, building a new factory can become faster and potentially less expensive.
That creates another barrier for countries trying to establish competing supply chains from scratch.
China's Advantage Is Not Just About Low Labor Costs
It is tempting to explain China's EV dominance simply by saying that manufacturing is cheaper because labor costs are lower.
That explanation is incomplete.
Modern battery and EV production is highly automated and capital-intensive.
The more important advantages include:
Scale: China has enormous battery and vehicle production capacity.
Supply-chain integration: Many stages of production are located within the same industrial ecosystem.
Manufacturing expertise: Years of large-scale production have created specialized knowledge and experienced suppliers.
Domestic demand: A huge EV market provides a large customer base.
Competition: Numerous manufacturers compete aggressively on cost and technology.
Infrastructure: Ports, roads, industrial parks, electricity networks, and logistics systems support large-scale manufacturing.
Investment: Significant capital has flowed into batteries, materials, EVs, charging, and related technologies.
These factors reinforce each other.
Why Other Countries Are Trying to Diversify
China's dominance also creates a potential vulnerability for the global EV industry.
If a supply chain depends heavily on one country for critical materials or components, disruptions in that country can affect manufacturers elsewhere.
The IEA has highlighted this concentration as a potential supply-chain risk.
For example, its analysis shows that China is the dominant refiner for several critical minerals, while battery component production is even more concentrated.
This is why the United States, European Union, Japan, South Korea, Indonesia, and other countries are investing in their own battery and EV supply chains.
The objective is not necessarily to eliminate Chinese suppliers. Instead, many countries are attempting to create additional sources of batteries, minerals, components, and processing capacity.
Can China Lose Its Dominance?
China's position is strong, but dominance does not mean permanent control.
Battery manufacturing is expanding in other regions.
The United States and Europe are building additional battery plants, while countries such as Indonesia and Morocco are attracting investment in battery materials and manufacturing.
The IEA also expects global supply chains to diversify over time.
However, diversification takes years because building a competitive battery ecosystem requires much more than constructing a factory.
A new industry needs suppliers, skilled workers, raw materials, chemical processing, equipment manufacturers, engineering expertise, logistics, customers, and sufficient production volume.
China already has much of this ecosystem in place.
The IEA therefore expects China to remain the largest producer of batteries and battery materials through 2035 under stated policies, even as production capacity expands elsewhere.
What This Means for the Global EV Market
China's position in the supply chain has consequences for consumers around the world.
Lower battery and manufacturing costs can help automakers offer electric cars at more competitive prices.
At the same time, concentrated supply chains can create concerns about resilience, trade restrictions, and exposure to disruptions.
For automakers, the challenge is therefore not simply to build an electric car.
They need reliable access to batteries, battery materials, semiconductors, motors, electronics, and other components at competitive prices.
The companies and countries that can secure those supply chains will have an important advantage as global EV adoption continues to grow.
Final Thoughts
China dominates the global electric car supply chain because it has built an entire industrial ecosystem rather than focusing on a single part of the EV industry.
It has enormous vehicle production, more than 80% of global battery cell production, dominant positions in cathode and anode materials, extensive mineral-processing capacity, strong LFP expertise, specialized manufacturing equipment, and a huge domestic EV market.
The most important point is that these advantages are interconnected.
A battery factory benefits from nearby material suppliers. Material suppliers benefit from large battery manufacturers. Automakers benefit from competitive battery prices. Consumers create demand for more electric cars, which encourages even more investment.
That creates a powerful industrial cycle.
Other countries are now trying to build alternative supply chains, and global production is gradually becoming more diversified. But because China's advantage extends across so many stages of the EV ecosystem, changing the global balance will likely take considerable time.
For now, when people talk about the global electric car supply chain, China remains at the center of the conversation.
