Why is LG Energy Solution shifting its North American factory output from EV batteries to energy storage systems (ESS)?

LG Energy Solution is shifting its North American factory output to energy storage systems (ESS) because demand for large battery cells to store power is booming—driven largely by the rapid buildout of AI data centers—and because the anticipated EV boom has not materialized as expected, leaving excess EV battery manufacturing capacity. As stated in the article, 'Most of LG Energy’s North American factories are making energy-storage batteries, or gearing up to,' and Robert Lee, the company’s regional president, noted that ESS represents 'the growth that we didn't expect.' The pivot is also a strategic response to underutilized U.S. battery factories built earlier this decade with tens of billions invested in anticipation of stronger EV demand.

What technical challenge does LG Energy face in producing ESS batteries, and how does it differ from its traditional EV battery chemistry?

LG Energy faces the challenge of developing lithium iron phosphate (LFP) battery chemistry—a technology it had little prior experience with—because LFP is preferred for energy storage systems due to its safety and durability, despite having lower energy density than LG’s specialty nickel-based batteries. As the article explains, 'Moving to ESS batteries has been more complicated than flipping a switch. LG Energy needed to develop a new battery chemistry... lithium iron phosphate (LFP), a market that has been dominated by Chinese manufacturers,' and while LFP is also used in some EVs, 'it has lower energy density than nickel-based batteries... which means shorter driving ranges'—a trade-off LG accepts for ESS applications where longevity and thermal stability matter more than range.
