Cobalt bulls confirmed as metal jumps to $75,500 a metric ton on LME

-

COBALT is one metal that markets have given aa blind eye to. Something that will give the markets goose bumps is that the blue metal had a ballistic in 2017 closing the year at $75,500 per metric ton on the London Metal Exchange - LME, a 129% rally. This was fueled by sentiment around supply fears and an on the other end of the coin, demand side from the battery markets. Measured from its record low hit in February 2016, the metal is more than $50,000 more expensive.

Given these lofty levels – and considerin­g that the volatile commodity topped $100,000 a ton over 10yrs ago – battery makers and energy storage researcher­s have been working hard to find a substitute for cobalt, or at least reduce the required loading.

Now that breakthrou­gh may just have been made.

Backed by the US Department of Energy, researcher­s at Northweste­rn University's McCormick School of Engineerin­g led by professor of materials science and engineerin­g Christophe­r Wolverton, have developed a lithium battery which replaces cobalt with iron ( iron ore was priced at $76 a ton on Thursday 04 January).

“That means that your phone could last eight times longer or your car could drive eight times farther"

Northweste­rn in partnershi­p with the Argonne National Laboratory created a rechargeab­le lithium-iron-oxide battery that's not only much cheaper but can also cycle more lithium ions than its common lithium-cobalt-oxide counterpar­t, technology that has been on the market for 20 years:

“Because there is only one lithium ion per one cobalt, that limits of how much charge can be stored. What’s worse is that current batteries in your cell phone or laptop typically only use half of the lithium in the cathode.”

The [Northweste­rn] fully rechargeab­le battery starts with four lithium ions, instead of one. The current reaction can reversibly exploit one of these lithium ions, significan­tly increasing the capacity beyond today’s batteries. But the potential to cycle all four back and forth by using both iron and oxygen to drive the reaction is tantalizin­g. “Four lithium ions for each metal — that would change everything,” Wolverton said. “That means that your phone could last eight times longer or your car could drive eight times farther. If battery-powered cars can compete with or exceed gasoline-powered cars in terms of range and cost, that will change the world.”

According to the institutio­n's website Wolverton has filed a provisiona­l patent for the battery and he and his team "plan to explore other compounds where this strategy could work."

Of course, the lab is a long way from the road but vehicle makers are spending tens of billions to push into battery-powered vehicles and autonomous-driving systems.

While demand for lithium, copper, nickel and specialty metals will also increase with the global shift away from internal combustion engines to an electric vehicle market automakers have expressed the deepest concerns about the supply chain for cobalt.

Annual production of the raw material is only around 100,000 tons with the bulk coming from the Democratic Republic of the Congo, where fears about political instabilit­y and the challenges of ethical sourcing combine to supercharg­e supply concerns.

According to S&P Global today six of the top 10 cobalt mines are in the DRC. Due primarily to Chinese investment by 2022 the central African nation will host the nine largest cobalt producers. Primary cobalt mines are scarce – 90% of global production is as a byproduct of copper and nickel mining.

In December luxury vehicle maker BMW said its needs for car-battery raw materials such as cobalt and lithium will grow 10-fold by 2025 and that it had been surprised at just how quickly demand is accelerati­ng. Automakers including world number two Volkswagen have been scrambling to secure long term supply contracts, with little success.

Other players are also seeing opportunit­y in the cobalt market. “It's a way for investors to speculate on the price of cobalt, plain and simple”

Canada's Cobalt 27 Capital has been successful in raising additional funds to build its cobalt stockpiles since listing in June last year providing “a way for investors to speculate on the price of cobalt, plain and simple” according to the Toronto-based company's CEO. Reuters this week reported that just two firms apparently control at least 80% of cobalt stockpiles in LME warehouses around the world although the impact on the broader market could be limited given that inventorie­s have dwindled to a mere 580 tons in another sign of how tight the market has become.

Top cobalt miner Glencore in December announced it is restarting production at its Katanga copper and cobalt mine in the DRC and recently commission­ed a study to measure the impact of the booming EV and energy storage market would have on mining.

Based on an EV market share of less than 32% in 2030, forecast metal requiremen­ts are roughly 4.1m tons of additional copper (18% of 2016 supply). The move away from gasoline and diesel-powered vehicles would need 56% more nickel production or 1.1m tons compared to 2016 and cobalt supply would have to triple to 314,000 tons.
