Europe has taken some big swings in the battery industry in recent years and has made a couple of high-profile misses.
asserted
Europe → publish → misses
Both Sweden's Northvolt, external and Norway's Morrow, external filed for bankruptcy and there are fears in Europe that the continent has missed another technology shift.
asserted
continent → file → shift
But the length of time required to bring new products to market, coupled with brutal competition, especially from China, means taking a substantial risk.
asserted
length → require → risk
Could the answer lie at an almost unimaginably small scale?
uncertain
answer → lie → scale
An increasing number of investors and researchers think so.
asserted
number → increase → investors
A single nanometre is one-billionth of a metre, but it's at that level that some of the most consequential work is being done.
asserted
some → do → work
"If you can make this work, it touches so many industries [but] it's a risky business," says Christian Rood, chief executive of Dutch tech firm LeydenJar.
asserted
Rood → make → LeydenJar
Named after a 18th century precursor to electric cells, LeydenJar uses a technique known as plasma deposition to make a lighter, more efficient anode – an essential component of all batteries.
asserted
LeydenJar → name → batteries
Silicon is a highly effective and cheap material to use in anodes, but pure silicon expands and contracts as the battery operates and is recharged, which causes it to crack.
asserted
it → use → anodes
However, using plasma deposition, LeydenJar can - layer by tiny layer - make an ultra-thin pure silicon foil which resists cracking, allowing a significant increase in battery life, charging speed, and energy density (up to 50%, according to LeydenJar).
uncertain
which → use → LeydenJar
"Where normally a pure silicon anode would fall apart, [this] remains stable, so it was a very wonderful invention," says Rood.
asserted
Rood → fall → ?
"We address the bottleneck in the battery.
asserted
We → address → battery
Commercial-scale production will start at the end of 2026, but it has taken 10 years to get to this point – the very definition of the time and investment required for so-called Deep Tech innovations.
asserted
it → start → innovations
"A lot of people talk theoretically about ecosystems; I can tell you this is one of our sources of competitive advantage," Rood says.
asserted
Rood → talk → advantage
"It's really the crossover from semiconductors to batteries that makes us different - once you've demonstrated the principle in the lab, industrialization requires you to work with the semiconductor technology and suppliers.
asserted
industrialization → make → technology
"That means a lot of risk, but also a lot of opportunity in terms of patenting, in terms of securing your whole intellectual property.
asserted
That → mean → property
And that's much more difficult to do in the US or in China."
asserted
that → do → China
One of those is Powall, a start-up in the Dutch city of Delft that is developing commercial-scale equipment for nanocoating the powders that are the raw materials of today's batteries.
asserted
that → develop → batteries
Again, the scale is tiny, and once again the technique was born in the semiconductor industry.
asserted
technique → bear → industry
Individual powder granules are measured in micrometres, the coatings in nanometres - they are applied using a technique known as atomic layer deposition.
Roderik Colen, CEO of Powall, tells me that the system offers multiple opportunities to adjust and improve the performance of today's batteries.
asserted
system → measure → batteries
"Your battery works less well than before after using it thousands of times - that degrading or aging can be slowed down when you're using a nanocoating," Colen explains.
"
asserted
Colen → work → nanocoating
You can have an exciting new material with a higher capacity or fast charging, all these novel developments.
asserted
You → have → capacity
They typically have one element which is very good, but they suffer on the durability side.
asserted
they → have → side
And that means they will never be a commercial product.
"
asserted
they → mean → ?
That's where we then come in, to give them the protective coating to effectively enable these new materials.
asserted
we → come → materials
"
The powders and the coating are carried by gas and brought together in a chemical reaction.
asserted
powders → carry → reaction
It is, says Colen, a precise but flexible process which can be almost endlessly adapted.
asserted
which → say → ?
"You have great accuracy in how thick you want to have it.
asserted
you → have → it
And that makes a difference in performance."
asserted
that → make → performance
Neither LeydenJar nor Powall are trying to build an entire battery, and both have commercial relationships with customers in Asia.
asserted
both → try → Asia
But Christian Rood of LeydenJar says companies like his can fortify Europe's position in what has become a global contest.
asserted
what → say → position
"The easy comparison is with semiconductors, where there's really a race for the best chip technology.
asserted
comparison → be → technology
[Dutch tech giant] ASML is not producing chips; it focuses on a critical step in the production of chips, and in that way, has a seat at the table when it comes to the whole semiconductor battle.
asserted
it → produce → battle
"This is our ambition as well – to have a position where our battery anode is so unique that we have an important position in the supply chain.
asserted
we → have → chain
"
So, how do these ambitions play into Europe's goals in the battery industry?
Alexander Brown is a senior analyst at the Berlin-based independent think-tank the Mercator Institute for China Studies (Merics).
asserted
Brown → play → Studies
"I think having one part of the supply chain based in Europe is great and if that can be a very advanced technological part, which offers the opportunity for high margins, that's fantastic
asserted
that → think → margins
," Brown tells me.
asserted
Brown → tell → me
But he cautions that while "there can be collaboration as well as competition at the same time", China in particular will continue to work to reduce its dependence on other regions.
asserted
China → caution → regions
"China is working very hard to develop local alternatives for technologies, including these niche technologies.
asserted
China → work → technologies
It's no secret that China would love to replace ASML - they're working very hard to do that, and it's not unforeseeable that they will achieve that goal eventually.
"
asserted
they → love → goal
