SEOUL: South Korean battery manufacturers are set to benefit from the 145 per cent tariff imposed by the second Donald Trump administration in the US on Chinese-made goods, including lithium-ion batteries for energy storage systems. This significant tariff hike aims to curb the competitive edge of Chinese batteries, which previously capitalised on lower levies than electric vehicle cells.
On April 10, the White House said that the 125 per cent tariffs on Chinese imports would rise from 34 per cent to 125 per cent, on top of an existing 20 per cent tariff. This unprecedented increase is part of measures addressing concerns over fentanyl influxes from China, effectively raising the prices of Chinese products 2.45 times.
According to a report by the Atlantic Council, a Washington-based think tank, China exported lithium-ion batteries worth US$15.3 billion to the US last year. With tariffs, the value of these exports could soar to approximately US$37.5 billion this year if trade volumes continue at a similar scale, making Chinese cells much more expensive in the US market. South Korean market tracker SNE Research noted that Chinese firms captured an 87 per cent share of the North American ESS battery market in the same period.
“Chinese lithium iron phosphate (LFP) batteries have been well-received in the US due to their competitive pricing over Korean rivals,” said an industry source on condition of anonymity. “These LFP products, which allow for a larger number of cells to be used compared to EVs, where the battery space is smaller, have been preferred by data centres for their cost efficiency.”
The source added, “Although Trump has left the door open for negotiations, Beijing is not budging, implementing stronger retaliative measures. Even if Washington-Beijing talks come through and reduce the tariffs set by the US, it will be unlikely for Trump to completely walk back on his tariff threat against China to return the rates to the previous 10.9 per cent levy on Chinese ESS batteries.”
China was able to dominate the ESS market in the US by setting low battery export prices per kilogram, widening the gap with Korean competitors. As of last November, the cumulative Chinese exports to the US totaled 678,000 tonns – roughly 11.7 times greater than South Korea’s 58,000 tonnes, according to the Atlantic Council.
LG Energy Solution is shifting its focus towards cost-effective LFP batteries for the US market, moving away from nickel, cobalt and manganese (NCM) cells.
“Due to the rising uncertainties on US trade policies, we cannot predict the impact of Trump’s 145 per cent tariffs on the Chinese companies,” said an LG Energy Solution official. “But one thing we can say for certain is that, with our seven battery manufacturing facilities, we are in the best position even among Korean companies to capitalise on our early US market penetration.”
The company looks to expedite mass production of LFP pouch cells at its Michigan plant by converting some of the production lines from EVs to ESS by later this year, a year ahead of its initial schedule. This strategic adjustment is intended to achieve cost-efficiency by using existing infrastructure rather than building a new facility.
Last month, the battery giant forged an agreement with Taiwan-based Delta Electronics to supply ESS cells in the US worth 4 GWh, enough to power over 400,000 households, by 2030.
Samsung SDI pursues a two-track strategy of advancing both its high-end nickel-based cells and LFP products for the US market.
The company recently secured a US$301 million deal to supply its flagship Samsung Battery Box (SBB) 1.5 to the US-based NextEra Energy. Although the company did not specify where the SBB 1.5 cells would be produced, sources predict it would be from its Ulsan plant or Hungary facility – both of which are expected to be imposed with a 25 per cent tariff, lower than Chinese rivals’ 145 per cent.
While boosting the sales of the SBB 1.5, it also plans to add the LFP version to the new SBB 2.0 that boasts enhanced cost competitiveness and capacity, which is set to start mass production from the first half of next year. Samsung SDI is also considering establishing a North American production base for ESS.
SK On is gearing up to launch LFP pouch cells for ESS, with the goal of achieving a meaningful outcome by late 2025. It strategically targets the US market, leveraging its Georgia plant and four new bases established through joint ventures with Hyundai Motor Group and Ford.
According to Global Market Insights, a Delaware-based research firm, the US ESS sector is expected to expand from last year’s US$10.67 billion to US$1.49 trillion by 2034, achieving an average annual growth rate of 29.1 per cent. - Korea Herald/ANN
