Lithium supply pipeline is filling but will it be enough? Andy Home

LONDON (Reuters) - The electric vehicle revolution is gathering momentum.

Barely a week goes by without a fresh, starting revelation, whether it be Sweden’s Volvo promising to phase out traditional internal combustion engines from 2019 or France aiming to end the sale of gasoline and diesel vehicles by 2040.

And, of course, leading the electric charge is the poster child of the green technology revolution, Tesla, which is gearing up to roll out its Model 3, the long-awaited break-out from niche to mass market.

The ambition is to be producing 20,000 per month by the end of the year. Whether reality matches such lofty goals remains to be seen. Tesla delivered around 47,000 vehicles in the first half of the year, at the lower end of its own forecasts, due to a “severe shortfall” of battery packs.

Tesla shareholders are used to this sort of thing but the battery pack delays are a reminder that this accelerating technology revolution rests on a long, complex and still-evolving materials supply chain.

We don’t know at which precise point of that chain Tesla’s battery bottle-neck appeared, but questions over the reliability of battery materials supply go all the way up the chain to the brine lakes of the Atacama Desert in South America.

Simply put, will there be enough lithium, and lithium in the right chemical composition, to support exponentially growing demand for batteries?


A year or so ago, the answer appeared to be “no”, which is why lithium prices went ballistic and the rest of the world outside what was then an esoteric, speciality market sat up and paid attention.

Spot prices have since calmed down, that for lithium carbonate currently trading in a stable $18.00-$21.70 per kg range, compared with over $25 in early 2016, according to the publication “Industrial Minerals”.

That’s in part due to a first-stage supply response.

New producers such as Orocobre’s Salar de Olaroz brine operations in Argentina and Neometal’s Mt Marion hard-rock mine in Australia are ramping up. More will join them over the next 18 months.

The existing oligopoly, comprising FMC Corp, Albemarle and Chile’s SQM, is meanwhile flexing its collective capacity muscles.

Analysts at “The Lithium Spot” expect supply to grow by around 35,000 tonnes in lithium carbonate equivalent (LCE) terms to 235,000 tonnes this year. That, they note, is pretty much in line with the average demand forecast, meaning “demand is either right in line or could be slightly outpacing supply for 2017.”

They expect another 60,000 tonnes of additional supply to kick in over the course of 2018.

The assumption is that all the new capacity ramps up smoothly. It’s a big assumption.


As the first-stage supply reaction kicks in, a second one is now starting to take shape.

The two leaders in this chase for more production are Chile’s SQM and China’s Jiangxi Ganfeng Lithium, which is now big and integrated enough to claim at least honorary place at the lithium top table.

The two companies have joined forces with junior miner Lithium Americas and Thai energy company Bangchak to develop the Cauchari brine operations in Argentina with first-phase 25,000-tonne per year LCE production pencilled in for 2019.

Hot on the heels of SQM’s foray across the border came a July 11 announcement it will acquire a 50 percent stake in Kidman Resources, which is developing the Mount Holland hard rock project in Western Australia. First production at the 40,000-tonne per year LCE operations is also scheduled for 2019.

In addition, SQM is expanding its existing Chilean operations as it seeks to “capture the opportunities that arise in the lithium market”, to quote company Chief Executive Patricio de Solminihac.

Solminihac said that SQM estimates demand for lithium is currently around 200,000 tonnes LCE but “growing at rates of nearly 14 percent per year.”

“We believe it is highly probable that worldwide demand will exceed 500,000 tonnes by 2025.”


All of which may be good news for Tesla and its peers sitting at the other end of the supply chain but it would seem to bode ill for the countless junior miners aiming for a piece of the lithium action.

The big three, or big four if Ganfeng is included, are understandably keen not to loosen their historic grip on the market even as it enters a period of potentially explosive growth.

But those hoping to form part of a third, future supply wave shouldn’t lose hope.

Because while supply appears to be firming up, demand remains a fast-moving, elusive part of the price equation.

As recently as March this year SQM said it believed lithium demand “could grow over 10 percent per year in the near term”. Fast forward four months and it has lifted that estimate by four percentage points.

And this, remember, is one of the most knowledgeable players in the lithium space with more than 20 years of operational and marketing experience.

If it is being wrong-footed by the speed of change in lithium battery usage, it’s a fair bet that everyone else is struggling to make sense of such dynamic fundamentals.

The potential for supply-demand gaps to open up over the coming decade is significant.

Even a hardening consensus that there will be enough supply for the next two or so years rests on a series of questionable assumptions about how efficiently new supply can be brought on stream and then integrated into the existing production chain.

Beyond that short-term timeframe, the uncertainties just grow ever larger.

Joe Lowry, lithium industry consultant and commentator, takes the view that even with the recent spate of new project announcements, it is quite possible that a “supply shortage will cause significant issues in the battery supply chain by 2023.” (“Lithium Investment at the Crossroads”, July 17, 2017).

Even relatively advanced projects are still struggling for finance despite all the media hype around lithium, according to Lowry, while Tesla’s charismatic chief executive Elon Musk “seems to think that if he builds cars, the lithium will come.”

Actually, even Mr Musk might be having second thoughts on lithium supply after those “severe delays” in getting battery packs in the first half of the year.
