China Is Winning the Next Battery Race — and the West Is Already Playing Catch-Up

For years, the strategic battle over electric vehicles was largely described as a race for lithium.

Then came cobalt.

Then graphite.

Now the battery industry is preparing for another shift — and China is already moving first.

The technology is sodium-ion batteries, a chemistry that replaces lithium with sodium, one of the most abundant elements on Earth. It will not replace lithium-ion batteries everywhere. Its lower energy density remains a major disadvantage for long-range electric vehicles.

But that may not matter.

Sodium-ion could become particularly important in energy storage, lower-cost electric vehicles, commercial fleets and applications where safety, cold-weather performance and raw-material security matter more than maximum range.

And China has built something the West currently lacks: an industrial ecosystem capable of turning the technology into mass production.

The Financial Times reports that China now has more than 400 GWh of operating and planned sodium-ion gigafactory capacity, compared with about 11 GWh across the rest of the world. CRU says 98% of announced sodium-ion cell capacity and more than 99% of announced cathode-material capacity is located in China.

That is not merely a technological lead.

It is a manufacturing lead.

And manufacturing leads tend to become technological leads when the technology is still improving.

The attraction is simple: sodium is everywhere

Lithium-ion batteries depend on materials whose supply chains have become strategically sensitive.

Sodium-ion changes the equation.

Sodium is abundant, including in ordinary salt and seawater. CRU notes that sodium-ion cells also eliminate lithium and copper from important parts of the cell design, using aluminium as the anode current collector instead of copper.

That does not mean sodium batteries eliminate every critical mineral.

They don't.

Some sodium-ion chemistries still use materials such as nickel, copper or vanadium, while the hard-carbon supply chain required for sodium-ion anodes remains relatively immature and heavily concentrated in China. The International Energy Agency also notes that sodium-ion manufacturing capacity remains tiny compared with lithium-ion.

So the real story is not “lithium disappears.”

It is diversification.

A world with both lithium-ion and sodium-ion batteries is less exposed to a single battery chemistry and the raw materials behind it.

That has enormous strategic value.

China is not waiting for the perfect battery

This is where China's approach becomes particularly interesting.

Instead of waiting until sodium-ion becomes the best battery for every application, Chinese companies are putting it into markets where its characteristics already make sense.

CATL and Changan Automobile unveiled what CATL described as the world's first mass-production passenger vehicle equipped with sodium-ion batteries in February 2026.

The vehicle is scheduled for market launch in 2026.

CATL says its Naxtra sodium-ion battery can reach energy density of up to 175 Wh/kg and maintain more than 90% capacity at −40°C, while providing strong performance in extremely cold conditions.

That matters because cold weather is one of the traditional weaknesses of lithium-ion technology.

But the bigger development may actually be outside passenger cars.

The grid could be sodium's biggest opportunity

Electric vehicles attract the headlines, but stationary energy storage could be where sodium-ion becomes strategically important.

A grid battery does not need to carry its energy around on four wheels.

Weight and volume therefore matter less.

A battery sitting beside a solar farm can be larger and heavier if it is cheaper, safer and capable of thousands of cycles.

That is precisely where sodium-ion becomes interesting.

CATL launched its TENER Sodium energy-storage system in June 2026 and said it expects cumulative shipments to reach 1 GWh by the end of the year, with international deliveries scheduled to begin in June 2027.

Even more revealing, CATL and energy-storage company HyperStrong signed a 60 GWh, three-year sodium-ion supply agreement in April 2026 — described by CATL as the world's largest sodium-ion energy-storage cooperation agreement.

This is no longer a laboratory experiment.

It is an industrial bet.

And China has already built the factory network

This is perhaps the most important part of the story.

Technological breakthroughs are easy to announce.

Factories are harder.

China has spent years building enormous battery-manufacturing capacity for lithium-ion batteries. That infrastructure provides an advantage when manufacturers begin adapting processes, equipment, suppliers and engineering expertise to new chemistries.

CRU estimates that China accounts for 98% of announced sodium-ion cell capacity and more than 99% of announced cathode-material capacity. It has tracked more than 300 GWh of announced cathode capacity and 370 GWh of cell-production capacity specifically for sodium-ion.

Carnegie Endowment reaches a similar conclusion from a geopolitical perspective: as of 2026, sodium-ion is being commercialised at scale essentially entirely in mainland China, while Western projects remain at pilot or early-commercial stages.

That creates a familiar pattern.

China does not necessarily need to invent every technology first.

It needs to become exceptionally good at scaling the technology.

Once production reaches enormous volumes, costs fall, suppliers improve, engineers gain experience and manufacturers learn what customers actually want.

That creates a feedback loop.

More factories → more production → lower costs → more adoption → more investment → better batteries → more factories.

The West has the science. China has the ecosystem.

This is where the phrase “the West is falling behind” needs some qualification.

Western companies have not abandoned sodium-ion.

There are projects in Europe and the United States, including efforts by companies such as Tiamat and Alsym, while major automakers and battery companies have continued researching alternative chemistries.

But the problem is scale.

Carnegie's analysis found that the US had only two sodium-ion developments moving toward commercialisation, while one major American sodium-ion company entered bankruptcy in 2025. Europe has also experienced setbacks, with some projects delayed or abandoned.

Meanwhile, Chinese companies are already producing vehicles and preparing commercial energy-storage deployments.

This is the difference between research leadership and industrial leadership.

The laboratory may be global.

The factory is increasingly Chinese.

But sodium-ion is not a magic replacement for lithium

There is an important catch.

Sodium-ion batteries generally have lower energy density than leading lithium-ion chemistries.

For a long-range electric SUV, that can mean more battery mass or less range.

That is why analysts increasingly see sodium-ion as complementary to lithium-ion rather than an outright replacement.

CRU expects sodium-ion to find particular opportunities in energy storage, two- and three-wheelers, low-voltage applications, power tools and other markets where its specific advantages outweigh its energy-density disadvantage.

The IEA likewise says the technology currently faces a much smaller supply chain and manufacturing base than lithium-ion.

So the future may not be:

Sodium beats lithium.

It may be:

Sodium and lithium divide the market.

That distinction matters.

The economics could change the equation

The most important question is cost.

The basic argument for sodium-ion is compelling: if you can replace expensive or volatile raw materials with abundant ones, the underlying battery could eventually become cheaper.

But “eventually” is doing a lot of work.

CRU currently cautions that sodium-ion has not automatically become cheaper than lithium-ion because manufacturing costs remain high while the supply chain is still being developed. Its analysts expect some sodium-ion energy-storage chemistries to reach cost parity with LFP later in the decade rather than immediately.

Other analysts are considerably more optimistic.

The Financial Times reports that analysts see sodium-ion potentially reaching cost parity with lithium-ion as early as 2027, while Morgan Stanley has projected that sodium-ion could become substantially cheaper than some lithium-ion alternatives as production scales.

The precise number is less important than the underlying possibility.

If sodium-ion becomes cheap enough, the economics of energy storage could change dramatically.

The patent race matters too

China's advantage isn't just factories.

It is intellectual property, research talent, suppliers, venture capital and accumulated battery expertise.

CATL says it has invested nearly €1.2 billion in sodium-ion research over the past decade, involving more than 300 R&D professionals. The company says it has accumulated more than 1,600 sodium-ion patent families and more than 200 globally granted patents.

That illustrates a larger industrial strategy.

China has spent years building expertise across the entire battery chain:

minerals → materials → cathodes → anodes → cells → battery packs → vehicles → charging → recycling.

Sodium-ion is entering that ecosystem rather than starting from zero.

That is a major advantage.

The geopolitical implications are bigger than EVs

This is ultimately not just a story about electric cars.

It is about energy security.

Governments have spent years worrying that dependence on lithium, cobalt, graphite and other materials could create strategic vulnerabilities.

But replacing one dependency with another does not automatically solve the problem.

If sodium-ion becomes globally important while China controls most of the factories, cathode materials, hard-carbon supply chains and intellectual property, the geopolitical dependency simply changes shape.

The mineral may become abundant.

The manufacturing capacity may not.

That is why China's sodium-ion push deserves attention far beyond the battery industry.

It is another example of a broader Chinese industrial strategy: identify a technology that could become strategically important, build domestic capacity early, integrate it with existing manufacturing infrastructure and push it toward commercial scale before competitors have decided whether the market is large enough to justify the investment.

Africa should be watching this very closely

For countries such as Nigeria, this technology presents an unusual opportunity.

Africa does not necessarily need to reproduce China's entire battery industry.

But sodium-ion could make electric mobility and stationary storage more attractive in markets where affordability matters more than maximum driving range.

Think electric motorcycles.

Three-wheelers.

Urban delivery vehicles.

Buses.

Solar-storage systems.

Mini-grids.

Backup power.

Telecom infrastructure.

Agricultural equipment.

In many of these applications, the question is not whether a battery can deliver 800 kilometres of range.

It is whether the battery is affordable, safe, durable and available.

That is a very different market.

And it is one in which sodium-ion could become increasingly relevant.

The real battery race is changing

For much of the last decade, the battery race was about who could produce the most powerful lithium-ion cell.

The next phase could be about something broader:

Who controls the widest menu of battery chemistries — and who can manufacture them cheaply at enormous scale?

China is already moving in that direction.

CATL is developing lithium, sodium and other battery technologies simultaneously. Chinese automakers are beginning to integrate sodium-ion into production vehicles. Energy-storage companies are signing contracts measured in tens of gigawatt-hours.

Meanwhile, Western companies are still trying to determine whether the technology deserves large-scale investment.

That hesitation could become costly.

Because once a battery chemistry reaches mass production, catching up is no longer simply a scientific problem.

It becomes a manufacturing problem.

A supply-chain problem.

A capital problem.

A workforce problem.

And ultimately, a time problem.

China appears to understand that.

The sodium-ion battery may not kill lithium-ion.

It may not even become the dominant battery chemistry.

But China is positioning itself so that whatever the market becomes, Chinese manufacturers are already sitting near the centre of it.

That may be the bigger story.

The next battery war may not be won by whoever discovers the best chemistry.

It may be won by whoever builds the factories first.
