LG Energy solution (Lges) is now the largest lithium-iron phosphate (LFP) battery manufacturer in the country, specifically for the roster scale market. The Korean company began to produce LFP cells at his New plant in Holland, Michigan, last month, and Solar Power World This week was able to visit the site and see the production on two lines. By the end of the year a third rule must be carried out and the factory will ultimately have an annual production capacity of 16.5 GWh of battery components for energy storage systems (ESS).
The buildings with white roof are the ESS editions in Holland for LG Energy Solution.
Lges has been working in Holland since 2012, first as EV -battery manufacturer under the name “LG Chem”. In 2022, the company announced an investment of $ 1.4 billion to start the production of ESS battery in an extension on site. The decision to support an ESS-Build-Out about EV was wise, because today’s EV market is confronted with decreasing customer demand and reduced federal support.
“Ess was the ugly duckling for LG for LG,” said Jaehong Park, CEO by LG Energy solution Vertech, the stationary storage arm of LGEs. “The financial performance of ESS in the past was difficult,” and EV was a much larger financial director for the company. But now Lges sees more growth for ESS and has four times more ESS production capacity than last year, said Park.
That is largely the most important point of discussion for industry: regardless of the subsidies offered by the federal government, energy storage is to stay here. Although the latest designs of the Congressional Budget Bill have made considerable cuts on the clean energy stimuli set in the Inflation Reduction Act (IRA), energy storage has one small victory. In the current invoice language, energy storage projects would still have access to the IRA’s original percentages of the ITR tax credit (ITC), while Solar Project subsidies can receive an accelerated phase down. It seems like a recognition of the congress about how important energy storage becomes for the growing electricity grid of America.

“There is no short -term alternative to support the tax increase,” said Park, and noted that the more data centers and other users of large electricity come online, the country cannot build “traditional” fuel plants quickly enough. Energy storage is the most suitable option to support intermittent energy sources (ie solar energy) to run the grid. “Without [supportive policy]Ess will delay, but it will bounce back. It is necessary, “he said.
The LG Energy Solution factory in Holland is currently only making cells and will eventually start compiling modules later this summer.
To make the cells, a mixture takes raw materials and adds binders and solvents to make a slurry. Foil is covered with the slurry, which goes through different steps to roll it up to the right thickness. One mono-cell consists of a cathode and anodal layer in combination with LGE’s safety-strengthened separator (SRS). Subsequently, 40 mono cells are stacked with one extra anodal layer, tabs are welded together and then they are slid into aluminum bags. The bag is closed, electrolyte is injected and soaked by the SRS. These bags are then stacked in modules, which are then containerized for storage of grid or residential applications.

Park said that the modules are sent to the Lgesa factory in Arizona to be assembled in Bess from LG Energy Solution brand. But soon Lges will open an assembly factory outside of Chicago to serve its customers in the Eastern US.
“Normally we don’t do modules or containers,” Park said about the production area of LGEs, but the company wanted to use its internal expertise that has already been developed through its EV partnerships to perform more ESS assembly in the United States.
Since Lges makes the battery cells on American soil, his Bess is easily eligible Domestic content adders on the ITC, as is currently written in the law. Depending on how much of the IRA remains intact in the final budget law, Lges Bess can be a hot commodity in the country.
US Battery Manufacturing Notes: Hithium has a 10-GWH LFP battery assembly factory in Texas, but it does not make the cells in the United States. Canadian solar subsidiary e-storage is building a 3-GWH LFP cell and module factory in Kentucky, but it is not yet complete. Aesc has reduced its EV -battery production -factory in Tennessee to produce LFP cells for ESS (Specific Fluence), although the annual production capacity of the plant has not been unveiled (previously estimated at 3 GWh for EV).
