LG Energy Solution (LGES) is now the nation’s largest lithium-iron phosphate (LFP) battery cell producer particularly for the grid-scale market. The Korean firm started producing LFP cells at its new plant in Holland, Michigan, final month, and Photo voltaic Energy World was capable of tour the location this week and see manufacturing on two strains. A 3rd line must be working by the top of the 12 months, and the plant will finally have an annual manufacturing capability of 16.5 GWh of battery parts for vitality storage techniques (ESS).
The white-roofed buildings are the ESS editions in Holland for LG Vitality Answer.
LGES has operated in Holland since 2012, first as an EV battery producer beneath the “LG Chem” title. In 2022, the corporate introduced a $1.4 billion funding to start out ESS battery manufacturing at an enlargement on-site. The choice to help an ESS build-out over EV was smart because the EV market of at present faces waning buyer demand and lessened federal help.
“ESS was the ugly duckling for a while for LG,” stated Jaehong Park, CEO of LG Vitality Answer Vertech, the stationary storage arm of LGES. “The monetary efficiency of ESS prior to now was tough,” and EV was a a lot bigger monetary driver for the corporate. However now LGES sees extra progress for ESS and already has four-times extra ESS manufacturing capability than final 12 months, Park stated.
That’s largely the primary speaking level for the trade: Whatever the subsidies supplied by the federal authorities, vitality storage is right here to remain. Whereas the most recent drafts of the congressional finances invoice have made vital cuts to wash vitality incentives established within the Inflation Reduction Act (IRA), vitality storage has one small win. Within the current bill language, vitality storage initiatives would nonetheless have entry to the IRA’s authentic funding tax credit score (ITC) percentages, whereas photo voltaic undertaking subsidies might obtain an accelerated phase-down. It looks like an acknowledgment from Congress at simply how necessary vitality storage is turning into to America’s increasing electrical grid.

“There’s no short-term various to help the load enhance,” Park stated, noting that as extra knowledge facilities and different large-electricity customers come on-line, the nation can not construct “conventional” gas crops quick sufficient. Vitality storage is the best-fit choice to help intermittent vitality sources (i.e., photo voltaic) to maintain the grid working. “With out [supportive policy], ESS will sluggish however it’s going to bounce again. It’s vital,” he stated.
The LG Vitality Answer plant in Holland is at present making simply cells and can finally start assembling modules later this summer season.
To make the cells, a mixing room takes uncooked supplies and provides binders and solvents to make a slurry. Foil is coated with the slurry, which passes by means of numerous steps to roll it to the suitable thickness. One mono-cell consists of a cathode and anode layer mixed with LGES’s safety-reinforced separator (SRS). Then 40 mono-cells are stacked with one further anode layer, tabs are welded collectively after which they’re slid into aluminum pouches. The pouch is sealed, electrolyte will get injected and it soaks by means of the SRS. These pouches then get stacked into modules, which is able to then be containerized for grid-scale storage or residential purposes.

Park stated that the modules shall be despatched to LGES’s plant in Arizona to be assembled into LG Vitality Answer-branded BESS. However quickly, LGES will open an meeting plant outdoors Chicago to serve its Japanese-U.S. clients.
“We usually don’t do modules or containers,” Park stated of LGES’s manufacturing space, however the firm wished to make use of its in-house experience already developed by means of its EV partnerships to carry out extra ESS meeting in america.
Since LGES is making the battery cells on American soil, its BESS simply qualify for domestic content adders to the ITC, as at present written into regulation. Relying on how a lot of the IRA stays intact within the remaining finances invoice, LGES BESS might be a scorching commodity within the nation.
U.S. battery manufacturing notes: Hithium has a 10-GWh LFP battery assembly plant in Texas, however it’s not making the cells in america. Canadian Photo voltaic subsidiary e-STORAGE is constructing a 3-GWh LFP cell and module plant in Kentucky, however it’s not but full. AESC has retooled its EV battery manufacturing plant in Tennessee to provide LFP cells for ESS (specifically Fluence), though the plant’s annual manufacturing capability has not been revealed (beforehand estimated at 3 GWh for EV).
