The Cobalt Story Is Stuck in 2016

There is a story about electric cars that refuses to die.

It usually goes something like this:

Children in the Democratic Republic of Congo dig cobalt out of dangerous mines.

Cobalt goes into batteries.

Electric cars need batteries.

Therefore, when you buy an electric car, you are indirectly supporting child labour.

It is a powerful story.

It is also increasingly outdated.

The tragedy of child labour in Congolese mining is real. The exploitation is real. The dangerous working conditions are real.

But somewhere along the way, a 2014 statistic became an eternal statistic, and a supply-chain problem that once applied much more broadly to batteries became permanently associated with electric vehicles.

Meanwhile, the technology has changed.

The battery industry has changed.

The cobalt supply chain has changed.

But the headline has barely moved.

The famous 40,000 figure needs context

The number most frequently repeated is 40,000 children.

But 40,000 what?

It is not a contemporary global count of children mining cobalt for electric cars.

It originated from a UNICEF estimate from 2014 concerning approximately 40,000 children working in mines across southern DRC. Amnesty later used that figure in its investigation into cobalt supply chains. Amnesty documented children as young as seven working in dangerous artisanal mines and rightly exposed the failure of companies to adequately trace their cobalt.

That reporting was important.

It should not be rewritten.

But neither should the statistic be stripped of its original context and presented as though 40,000 children today are mining cobalt specifically to build electric vehicles.

That is not what the original estimate said.

And it certainly doesn't tell us what the cobalt supply chain looks like in 2026.

The irony is that phones were a major part of the original story

There is another detail that gets strangely lost.

When Amnesty published its landmark 2016 investigation, the companies prominently discussed were Apple, Samsung and Sony.

The title itself was:

“Child labour behind smart phone and electric car batteries.”

Amnesty's research found that cobalt from dangerous artisanal mines could enter supply chains supplying batteries used in consumer electronics and electric vehicles.

The problem therefore wasn't invented by the EV industry.

But over time, the story became almost exclusively an attack on electric cars.

That creates an odd contradiction.

The person typing a furious post about “blood cobalt” on a smartphone may be using a device whose battery relies heavily on cobalt chemistry.

Meanwhile, a growing proportion of electric vehicles are using batteries containing zero cobalt.

The EV industry has been quietly removing cobalt

This is perhaps the most important part of the story.

Lithium iron phosphate—LFP—batteries contain no cobalt.

And LFP is no longer some experimental alternative sitting on the margins of the EV industry.

It has become one of the dominant battery chemistries in the world.

According to the International Energy Agency, LFP accounted for more than 55% of EV batteries deployed globally in 2025, up from almost half in 2024.

In China, the shift is even more dramatic.

LFP supplied nearly three-quarters of China's domestic EV battery demand in 2024, with its share reaching around 80% in the final two months of that year.

And in 2025, more than 80% of EVs sold in China were reported to use LFP batteries.

That means the world's largest electric-car market has been rapidly moving toward a battery chemistry that doesn't require cobalt at all.

This isn't a minor technical footnote.

It fundamentally changes the cobalt argument.

Even more interesting: China helped drive the transition

There is another uncomfortable irony.

The country most aggressively scaling electric vehicles has also been one of the biggest forces behind the shift toward LFP.

Chinese battery manufacturers have become dominant in LFP production, while Chinese automakers have deployed the chemistry at enormous scale.

The result is that one of the world's biggest transformations in automobile technology is simultaneously reducing the importance of cobalt in mainstream EV batteries.

The IEA says LFP's global deployment continued to expand rapidly in 2025, driven heavily by China and increasingly by emerging markets.

So the simplistic picture—

African child → cobalt mine → EV battery → Western electric car

—is increasingly incapable of describing the modern EV battery market.

And the cobalt supply chain itself has changed

The shift is not limited to battery chemistry.

Artisanal and small-scale cobalt mining in the DRC has also declined dramatically as a proportion of production.

According to the Cobalt Institute's summary of Benchmark Mineral Intelligence estimates, artisanal and small-scale mining accounted for around 10% of DRC cobalt production in 2018.

By 2024, the estimate had fallen below 2% of DRC production, approximately 1% of global cobalt supply.

That doesn't mean child labour has disappeared.

It hasn't.

It doesn't mean artisanal miners are suddenly safe.

They aren't.

And it certainly doesn't mean the DRC has solved the governance, poverty and labour problems surrounding mining.

It means something much narrower but extremely important:

The proportion of the global cobalt supply coming from artisanal mining has changed dramatically.

Yet the internet continues to recycle the old supply-chain narrative as though nothing happened.

This is where the debate becomes intellectually dishonest

There are two bad arguments.

The first is:

“Child labour exists in cobalt mining, therefore electric cars are evil.”

That is an enormous logical leap.

The second is:

“EV batteries are increasingly cobalt-free, therefore child labour in Congolese mining doesn't matter.”

That is equally wrong.

The correct conclusion is much more complicated.

Child labour remains a serious human-rights issue.

Cobalt remains strategically important.

The DRC remains extraordinarily important to global cobalt supply.

Artisanal mining remains a poverty and governance problem.

Companies still need to know where their minerals come from.

But the specific claim that today's EV revolution is fundamentally dependent on children digging cobalt out of Congolese pits is becoming less accurate every year.

And there is an even bigger hypocrisy

Look at what happened.

Consumers were told:

“Don't buy electric cars because children mine the cobalt.”

So the industry responded.

Engineers developed alternative chemistries.

Manufacturers reduced cobalt intensity.

LFP became cheaper.

Battery companies scaled it.

Automakers adopted it.

China deployed it at enormous scale.

And now LFP is the dominant battery chemistry globally.

In other words, technology did exactly what technology is supposed to do: it reduced dependence on a problematic input.

But the criticism often didn't evolve with the technology.

The headline remained.

The chemistry changed.

Meanwhile, your phone is a different story

Consumer electronics deserve far more attention in this conversation.

Lithium cobalt oxide remains an important chemistry for portable electronics because of its high energy density and suitability for compact devices.

That creates an uncomfortable question.

Why has the public conversation become so obsessed with the cobalt inside electric cars while paying considerably less attention to the cobalt-intensive batteries inside the devices billions of people carry every day?

The original Amnesty investigation was explicitly about smartphones as well as electric vehicles.

So if the moral argument is:

“We should not consume products connected to abusive cobalt mining,”

then apply it consistently.

Don't attack the electric car while pretending the smartphone in your hand is morally neutral.

The real scandal isn't electric cars

The real scandal is poverty.

A child should not be forced into a mine because their family cannot survive without the income.

A miner should not have to enter an unsafe tunnel without protective equipment.

A country possessing some of the world's most valuable strategic minerals should not remain desperately poor while global industries build fortunes from those minerals.

That is the story worth telling.

And it leads to a much harder question:

Why does the DRC still struggle to capture enough value from the minerals beneath its soil?

That is far more uncomfortable than blaming the person who bought an electric car.

Because the problem isn't simply that cobalt leaves Congo.

It is that Congo has historically occupied the weakest position in the value chain.

The ore is extracted.

Someone else processes it.

Someone else refines it.

Someone else manufactures the cathode.

Someone else makes the battery.

Someone else makes the vehicle.

Someone else captures the largest share of the value.

And then Africa gets another lecture about responsible consumption.

The narrative needs to catch up with reality

The fight against child labour should continue.

Corporate supply-chain accountability should become stronger.

The DRC needs better mining governance, education, worker protection and formalisation of artisanal mining.

Companies should know where their cobalt comes from.

Consumers deserve transparency.

But intellectual honesty requires updating the argument when the underlying facts change.

The famous 40,000 figure is more than a decade old.

Artisanal cobalt's share of DRC production has collapsed.

LFP batteries contain no cobalt.

LFP has become the dominant EV battery chemistry globally.

And China has driven much of that transition.

So perhaps it is time to retire one of the internet's laziest arguments:

“Electric cars are powered by child labour in Congo.”

The historical concern was legitimate.

The human-rights abuses were real.

But the modern battery industry is not standing still.

The technology moved.

The supply chain moved.

The chemistry moved.

The argument didn't.

And that may be the biggest problem of all.

Because when an important human-rights issue is turned into a frozen talking point, people stop investigating what is actually happening.

The children deserve better than that.

The Congolese people deserve better than that.

And consumers deserve a debate based on today's supply chains—not yesterday's headlines.
