FEATURE: Raw material supply a challenge to meet battery demand

Banner Image

As the Western world looks looking to increase battery making capacity, one challenge facing the industry is raw material supply and whether there will be enough to meet demand by 2030.

Battery maker Northvolt does not believe there will be enough raw material supply and refineries to supply the planned gigafactory capacities planned by 2030.

"This is exactly the eco-system that needs to be developed during the upcoming decade, not only to increase raw material supply but also the sustainability and reliability within that supply," Northvolt's director of communications and public affairs for the Nordics region Anders Thor told S&P Global Commodity Insights.

Northvolt has a broad strategy to ensure it had sufficient supply for its plants, he said, including setting up regionalized streams of raw material, or exploring and developing alternative materials, while recycling was key.

"Our goal is that by 2030, at least 50% of the raw materials we use for battery production should come from recycled materials," Thor said.

There is a need to diversify the raw materials being used in supply chains and use other materials, like sodium-ion, for appropriate applications, while government support is vital, AMTE Power CEO Kevin Brundish said.

Graphite producer Talga said challenges included a shortage of suitable deposits, ease of access to mining and availability of refinery capacity.

"There is a current push to speed up the permitting process for critical raw materials projects and while such changes would help, they would not solve the problem entirely," it said.

Talga plans to expand its initial battery anode project in Sweden from 19,500 mt/year to around 100,000 mt/year to meet around 10% of European anode demand by 2030, it said, adding that it was also conducting geological exploration to enable further expansions beyond 2026 to meet long-term demand.

On the other hand, clean battery developer Freyr Battery believes there are enough raw materials, related materials projects and overall capacity to meet the supply requirements in the coming decade, CEO Tom Einar Jensen said.

"We expect both supply and demand to grow tremendously, and naturally, we anticipate that there will be periods of temporary imbalance," he said. "Despite some volatility, we expect the future average raw material prices to be lower than they are today."

Platts, part of S&P Global, assessed seaborne lithium carbonate and lithium hydroxide at $76,000/mt CIF North Asia and $83,800/mt CIF North Asia Nov. 10, up 124.85% and 164.35%, respectively, since the start of 2022.

In Jensen's opinion, lithium could present the greatest challenge, as many projects in Europe and the US are "generally always off from commercial production."

However, Freyr has already secured most of the raw materials for its Customer Qualification Plant and for the initial phase of its Giga Arctic factory, while continually qualifying new materials and new suppliers.

Sufficient cobalt

The Cobalt Institute believes there will be enough cobalt to meet demand by 2030, although it will require investment, continued diversification and recycling, its president Adam McCarthy said.

Supply diversification could come from untapped reserves in Australia, while cobalt could also be sourced from tailings ponds from historical nickel and copper mining in Australia, the Democratic Republic of Congo and South America.

Recycling is also a growth sector, with around 10% of global cobalt supply currently recycled and that is set to grow with more recycling and more batteries coming to the end of life, McCarthy said.

"Policies to support and encourage and sometimes mandate recycling will be helpful," he said.

In the short to medium term there is expected to be some tightness in supply, but this will ease if investments continued to take place in new mines and processing facilities, he said.

"Just from land-based mining and recycling and seeing what else we can find in tailings, there is enough supply to meet demand -- we're pretty confident about that," McCarthy said.

Different battery chemistries will also have an impact on cobalt demand, although he expects demand to increase anyway, due to rising battery manufacturing.

"People talk about substitution of cobalt out of batteries...but the bottom line is that those technologies, besides LFP, are in their infancy and are not ready for mass market or being produced to scale," McCarthy said.

"We don't see cobalt-containing batteries going away any time soon -- once the competition is there, we'll be recycling so much, substitution will not likely be an issue in 10-15 years' time."

Refining gap

Meanwhile, the lack of conversion and refining capacity in Europe is also an issue, AMG Lithium Global Director Sales and Marketing Andre Majdalani said.

"Unfortunately, you can take it further upstream and wonder, how little is being done to start mining local deposits -- not that they would fully satisfy Europe's demand, but they would certainly help increase Europe's resilience," he said.

AMG is concentrating on Europe to start and plans to serve local cathode manufacturers with battery-grade lithium hydroxide from its refinery in Bitterfeld-Wolfen, Germany, which it is on track to commission in the second half of 2023.

It is planning to build five 20,000 mt/year lithium hydroxide modules that will be flexible in terms of feedstock, he said, reaching a capacity of 100,000 mt/year by 2030, when Europe's requirement is expected to be more than 550,000 mt/year.

Freyr's Jensen said he believed raw material shortages, particularly for lithium, could be alleviated by building out greater refining capacity in Europe, which would enable sourcing from a wider range of raw material suppliers.

However, McCarthy did not see the lack of refineries in the Western world being an issue, with it expecting Western governments to ensure investments in refining for all critical minerals to tackle China's dominance.

"For cobalt today, around 65% globally is refined in China, but the next biggest refinery is Finland with around 13% of global refined supply at Kokkola," he said.

There are investments in Europe and in Canada, in particular, and there is a political imperative to build refineries, as there are concerns about security of supply, meaning governments have to make it happen, McCarthy said.

South Korea's L&F to supply $9.95 bil of cathode materials to SK On over 6 years

South Korea's L&F Co signed a $9.95 billion deal to supply high-nickel cathode material to battery maker SK On over the next six years, the cathode materials company said March 25. The value of the supply contract was estimated by L&F and is effective March 22, 2024 to Dec. 21, 2030, as it builds up its supply of battery-related materials. High-nickel cathodes are necessary to extend the lifespan and capacity of secondary batteries. To boost its local production capacities, South Korea's Fair Trade Commission approved a plan by L&F to set up a joint-venture 120,000 mt/year battery precursor plant at Samangeum Industriale Complex, Gunsan, as early as 2025 to 2026, together with LS Corp. Also, the supply of the cathode material will be vital to SK On, which plans to start up its third electric vehicle battery plant at Seosan in 2025 with a production capacity of 14 GWh. In a related development, SK On will supply its high-nickel batteries to Swedish EV maker Polestar from 2025. Platts assessed spot battery-grade nickel sulfate with minimum 22% nickel content and maximum 100 ppb magnetic material at Yuan 30,500/mt ($4,238/mt) DDP China March 22, up Yuan 500/mt from the previous session, S&P Global Commodity Insights data showed.

Australia’s Pilbara, China’s Ganfeng to study setup of JV lithium plant

To consider conversion plant with 32,000 mt/year LCE output Uncertainty risks remain in China’s lithium markets Australian miner Pilbara Minerals said March 25 it signed a binding term sheet to complete a joint feasibility study on a downstream lithium conversion plant with China's Ganfeng Lithium Group, one of the world's largest lithium chemical converters. Global lithium salts prices have dived significantly in the recent past due to supply surplus amid expanding capacity and weakening demand. The feasibility study will consider a conversion plant that could produce 32,000 mt/year lithium carbonate equivalent of lithium chemicals (hydroxide and/or carbonate), along with a potential intermediate lithium chemical product in Australia, leveraging Ganfeng’s experience as a lithium chemical converter, Pilbara said in the statement. The feasibility study is expected to be completed in the March quarter of 2025, with an option to progress to a final investment decision and formation of a joint venture following that. This was not the first attempt for Pilbara Minerals to move into lithium chemicals conversion business. The company has made an FID in August 2023 for a demonstration plant within the Pilgangoora Operation JV in Western Australia with environmental technology developer Calix. Calix said the project was estimated to produce more than 3,000 mt/year of lithium phosphate at full capacity, using spodumene concentrate feed purchased by the JV from Pilbara on commercial terms consistent with market pricing. The plant was expected to produce first lithium salt in the June quarter of 2025 and ramp up to steady state production in the March quarter of 2026, Calix said. Cooperation with Ganfeng Lithium This was the first time Pilbara and Ganfeng Lithium are working together on a downstream lithium conversion plant. It could help Ganfeng Lithium lessen the impact from the US Inflation Reduction Act to establish the plant outside China. However, when and where the project would be situated remained unknown, industry sources said. Ganfeng Lithium held a 5.76% stake in Pilbara as of the first half of 2023, according to an interim report. Pilbara previously bumped up its supply of spodumene concentrate to China’s Ganfeng Lithium Group in January. According to an amendment made to an offtake agreement, Pilbara will supply spodumene to Ganfeng Lithium in the range of 260,000-310,000 mt/year over 2024-2026. Lithium carbonate prices Lithium carbonate prices in China plunged 85% from their peak seen in 2022 to a low of Yuan 90,000/mt ($12,487) in early January. The prices have moved up since then to Yuan 112,350/mt as of March 22, according to S&P Global Commodity Insights data. However, prices would continue to face pressure as downstream consumers have almost finished restocking while imports have stayed elevated and a small number of lithium salt producers in Jiangxi province planned to resume production, sources said. Market participants are keeping a close eye on the recovery of downstream demand in the upcoming peak season. The most active lithium carbonate contracts for July 2024 delivery on the Guangzhou Futures Exchange closed at Yuan 107,400/mt March 25, down 6.6% or Yuan 7,600/mt from the previous settled price, GFE data showed. The price direction highlighted the uncertainty risks in China’s lithium markets, sources said. Platts Connect: News & Insights (spglobal.com)

EU, Norway sign MOU on raw materials, battery value chains

MOU to develop into long-term cooperation in five areas First business match-making event to take place in April The EU and Norway signed a memorandum of understanding launching a strategic partnership to develop sustainable land-based raw materials and battery value chains, the European Commission said March 21. The MOU -- a building bloc of the EU-Norway Green Alliance announced in April 2023 -- is meant to lead to long-term cooperation between the EU and Norway in five areas: integration of raw material and battery value chains through joint projects and ventures; research and innovation; information exchange around environmental, social and governance (ESG) standards and practices; mobilization of financial instruments, notably through Invest EU, the European Raw Materials Alliance and the European Battery Alliance; and developing skills for high-quality jobs in the sectors. The EU and Norway will now work on implementing the roadmap for the partnership with the first business match-making event planned during the Hannover Messe trade fair on April 22. The MOU rests on the strength of Norway as a country rich in rare earths, magnesium, titanium, vanadium, phosphate rock and other resources, and with a large processing capacity for a few of these minerals, to which the EU adds value as an established and growing market for green technologies, including batteries with an estimated demand in 2023 of 175 GWh. The EU battery industry is the second largest in the world with existing facilities having up to 220 GWh of ramp-up capacity and an additional 1 TWh of battery manufacturing projects that have been announced or are currently under construction, according to the commission. With critical raw materials needed to deliver on green energy objectives, the commission has started to build a series of partnerships on raw materials with Canada and Ukraine in 2021, Kazakhstan and Namibia in 2022, Argentina, Chile, Zambia, the Democratic Republic of Congo and Greenland in 2023, and Rwanda in 2024. The partnerships are in line with the Global Gateway strategy, through which the EU will mobilize up to Eur300 billion ($325 billion), it says. Platts Connect: News & Insights (spglobal.com)

CERAWEEK: Energy industry has trapped itself with binary technology talk

Industry must be open to new technologies Wind, solar attack natural gas’ market share The energy industry has trapped itself with binary dialogue about being for one type of technology or another, when all resources need to work together to achieve energy transition goals, Tinker Energy Associates CEO Scott Tinker said March 22. The energy transition is not just about one technology, but rather a suite of technologies, panelists said at the CERAWeek by S&P Global energy conference in Houston. “What is nice about renewables and new technology is they're much more democratically distributed around the world,” said Andres Gluski, AES Corporation president and CEO. “The reality is a little bit more complicated. But I also think it's not rocket science.” However, the industry has to be careful about status quo because things are changing rapidly, Gluski added. “In the power industry, we're seeing once in a 100-year events, like floods and heatwaves, etc., occur every year.,” Gluski said. “The weather has changed. That’s the reality.” Industry leaders need to look at how to deliver the electricity with the lowest carbon and in most sustainable way possible, he added. Renewables versus fossil fuels Solar and wind costs have dropped remarkably over the years, Tinker said. “To make it reliable requires something sitting here waiting to back it up … and that something is expensive,” Tinker said about battery storage. “I think we have to be more open and candid about the actual cost of electricity to be integrated.” The domestic production of wind turbines is strong, with battery storage production to come, while domestic of solar panels will take longer, Gluski said. And while renewables do not generate 24 hours a day, coal is not going to come back regardless of political slogans, he added. “For a lot of these new technologies we need the regulators to be on top of it as a lot more is coming," Gluski said. The energy transition has to happen at a pace that’s politically sustainable, said David Victor, a professor of Innovation and Public Policy with the School of Global Policy and Strategy at University of California, San Diego. “I'm really concerned that we are overweighting the familiar,” Victor said. “We are overinvesting in things we know how to do and probably underinvesting in things that we don't yet know how to do.” Glue that holds it together “We got to figure out the glue that holds all this together,” said Hunter Hunt, chairman and CEO of Hunt Energy. There will be less natural gas needed than the industry thinks, but more than environmentalists think, he added. “Wind and solar are absolutely attacking natural gas’ share and they've decimated coal in the industrialized world,” Hunt said. “If natural gas is going to be a transition fuel, the industry needs to do its part to make sure that we're doing it in the right way. The future of energy can be seen in Texas today, Hunt said about the battery storage growth happening. There such a diversity in approaches with new technology and “we need all of it,” said Evelyn Wang, director of the Advanced Research Projects Agency-Energy with the United States Department of Energy. Houston, we have an opportunity “One of the things that is different today versus this time last year, is just explosion of activity in energy transition-related projects in Houston and Gulf Coast,” said Bobby Tudor, CEO Artemis Energy Partners and chairman of the Houston Energy Transition Initiative. “We have enormous competitive advantages here in this region to be a leader, and it's up to us to intentionally do that. … We intend to continue to exploit that advantage.” Texas has the largest concentration of technical talent in the world related to energy systems, Tudor said, adding the state is well positioned for the task due to its ports and access to wind and solar resources. A lot of the development in Texas has to do with permitting and the ability to get projects permitted and done, Tudor said, adding that process is much more difficult in rest of the country. The catch phrase should be “Houston, we have an opportunity” instead of “Houston, we have a problem,” said Atul Arya, S&P Global Commodity Insights senior vice president and chief energy strategist.
