S Korean EV producers pushed to reveal battery details

Market: Battery materials
13/08/24

South Korea's government has advised domestic electric vehicle (EV) manufacturers to disclose their battery information and to allow inspections after multiple fires have raised safety concerns.

It comes as authorities seek to ease EV owners' safety concerns after an EV earlier this month caught fire at an apartment complex in Incheon city and destroyed nearby cars. A fire at a lithium battery manufacturing plant at Hwaseong in June led to a chain explosion, killing 23 workers and injuring eight, according to South Korea's National Fire Agency.

South Korea's government formed a task force that carried out safety inspections at battery industrial sites, following the lithium battery manufacturing plant fire. The task force, led by its environment ministry, also inspected safety conditions of underground electric chargers and related facilities from July to early August, according to government agency the Office for Government Policy Co-ordination.

Multiple South Korean auto manufactures including Hyundai and Kia, as well as the South Korean units of global producers such as BMW and Mercedes-Benz, have released information about the installed batteries in their EVs. This has often been confidential and included their suppliers.

Hyundai and BMW Korea were among the first to disclose the information, with BMW Korea disclosing that the majority of its models use batteries from South Korean battery maker Samsung SDI, with the rest from Chinese battery manufacturer CATL. LG Energy Solution (LGES) and SK On are supplying most of Hyundai's EV batteries, with only the batteries for its Kona SX2 model from CATL. Kia also disclosed that the battery cells used in its EVs come from domestic producers LGES, SK On, as well as CATL. South Korea's Mercedes-Benz revealed that a number of its EV models use batteries from LGES, SK On, CATL, as well as fellow Chinese battery producer Farasis Energy.

South Korea's domestic sales of battery EVs (BEVs) in this year's first half fell by 15pc from a year earlier to 66,930 units despite firm domestic demand for BEVs in June. BEV sales in June rose to around 17,000 units, which was up by 16pc on the previous year and by 29pc against a month earlier.

Lithium prices unlikely to recover in 2025

London, 13 January (Argus) — Prices for lithium carbonate equivalent (LCE) are unlikely to recover this year, according to market participants, owing to high inventories and Chinese overcapacity. While the vast majority of firms have either suspended or trimmed production at costs above Argus -assessed prices (see graph) , a number of other factors have weighed on price rises, including redundant Chinese lithium refining capacity, inventories of low and mid-grade concentrate and end-of-life LFP batteries. Chinese lepidolite, African low-grade ores and Brazilian tailings are "not immune" to low prices, according to supply chain consultantcy SC Insights. Prices are currently far below highs of $80,000/t in late 2022, although not at record lows by historical standards. "We have put our lithium plant in Zimbabwe on ice for now, margins are just too tight," a southern Africa-based producer said. The market could start to recover in the second half of 2026 as carmakers turn increasingly towards lower-cost lithium iron phosphate (LFP) batteries, SC Insights said. Between 2025 and 2026, major carmakers will start "socialising the intensions of using more LFP and LFMP [lithium iron manganese phosphate]", with it especially vital that LFMP producers "react early and offer a cost-competitive solution in CAM/LIB [cathode active material/lithium-ion battery] spaces". SC Insights forecasts that global annual LCE production will tip over 2.5mn t of LCE by 2030 (see graph) , from just over 1mn t last year, based on the adoption of these newer battery chemistries. Buildout of this supply will depend, SC Insights said, on the proposed restriction of CAM/LIB technology by China. The buildout of Argentinian lithium production could be a key factor in 2025, according to SC Insights, after global mining giant Rio Tinto announced last October that it would buy Arcadium Lithium. Argentinian president Javier Milei and Rio Tinto held a meeting in December 2024 and although it is unclear what the results of that meeting were, the relationship between Rio Tinto and the Argentinian government could be important for the lithium market this year. Argentina holds the third-largest reserves of lithium at 3.6mn t behind Chile and Australia, and the second-largest pool of resources at 23mn t, behind Bolivia, according to the US Geological Survey in January.

Hyundai Motor plans $16.7bn Korean investment in 2025

Singapore, 9 January (Argus) — South Korean conglomerate Hyundai Motor, which owns major automotive brands Hyundai and Kia, plans to invest 24.3 trillion won ($16.7bn) in South Korea this year in what it said is its largest ever annual investment domestically. The domestic investment amount is W3.9 trillion or 19pc higher than in 2024, in a bid to "overcome the crisis" and "secure future growth engines" given global uncertainties through "continuous and stable" investment, said the group on 9 January. Around W12 trillion will go into its current investments and W11.5 trillion will go to research and development, while another W800bn will be injected into what it called "strategic investment". Hyundai Motor still plans to continue developing new electric vehicles (EVs) and accelerating the electrification transition, it said. A major investment in building an EV-only plant will be made this year, said the conglomerate. Kia's battery EV plant in Hwaseong that has a production capacity of 150,000 units/yr is still expected to be completed in the second half of 2025. Its EV plant in Ulsan is currently under construction and is expected to begin producing in the first half of 2026. Kia is expected to feature a full line-up of 15 EV models by 2027, while Hyundai is expected to have 21 EV models by 2030, said the group. The conglomerate sold around 4.14mn units of vehicles in 2024, down by 1.8pc on the year, mainly driven by lower domestic sales. Domestic sales totalled 705,010 units, down by 7.5pc on the year ,while its overseas sales were steady at almost 3.44mn units. A sales target of 4.17mn units has been set for 2025. South Korea's top battery maker LG Energy Solution (LGES), which supplies a significant number of batteries for Hyundai's and Kia's EV models, is expecting its 2024 operating profit and sales to see sharp falls, it said on 9 January. LGES earlier similarly indicated an uncertain outlook on the battery and EV market. LGES expects its 2024 operating profit to plunge by 73pc to W575.4bn and sales to fall by 24pc to W25.6 trillion. LGES expects to post its only quarterly loss of the year for October-December of W225.5bn, with sales expected to be down by 19pc on the year to W6.45 trillion during the quarter. LGES earlier has warned that significant cuts in capital expenditure from the firm during 2025 can be expected.

Lithium Americas increases Thacker Pass reserve

Houston, 7 January (Argus) — US lithium producer Lithium Americas raised its estimated mineral resource and reserves for the Thacker Pass lithium project, supporting an expansion that could boost its battery grade lithium carbonate capacity up to 160,000 metric tonnes (t)/yr. The updated proven and probable mineral reserve estimate for the Thacker Pass project now stands at 14.3mn t of lithium carbonate equivalent (LCE), marking a 286pc increase since the November 2022 feasibility study, according to the latest technical report. Thacker Pass is now the largest measured lithium reserve and resource in the world and has the potential to become an unmatched district, generating American jobs and helping the US regain independence of its energy supply, president and chief executive Jonathan Evans said. The increase enables a phased expansion with an 85-year life of mine (LOM), targeting 160,000 t LCE/year, split into four phases of 40,000 t LCE/yr each. Construction of each of Phases 1 through 4 is expected to be spaced four years apart. US automaker General Motors (GM) holds a 38pc ownership stake in the project. GM has secured an offtake agreement for 100pc of Phase 1 output for 20 years, and 38pc of Phase 2 output for 20 years, with a right of first offer on the remaining Phase 2 volumes. The updated operating costs (OPEX) are $6,238/t LCE under the production scenario, optimized for the first 25 years of the 85-year LOM; and $8,039/t LCE in the base case, which covers the entire 85-year LOM.
