Core News Facts Summary
On August 27, 2026, SK On signed a battery cell supply agreement with U.S. ESS company Neovolta Power at SK On’s Gwanhoon Campus in Jongno-gu, Seoul. Under the agreement, SK On will supply a total of 9 GWh of lithium iron phosphate (LFP) pouch battery cells to Neovolta Power over five years, from 2027 through 2031. The supply volume will be produced at SK On’s Georgia, USA plant, and industry sources estimate the contract value at approximately ₩1.5 trillion. SK On also plans to supply an additional 9 GWh of ESS-oriented LFP battery cells to Neovolta Power under a separate consignment-manufacturing contract within the year, which, combined with this agreement, would expand the total cooperation between the two companies to 18 GWh.

Mechanism-Perspective Impact Analysis
A five-year long-term contract incentivizes investment in standardizing and automating pouch-cell stacking, compression, and busbar-joining equipment. Unlike a one-off order, the same-spec cells will be produced repeatedly over five years, so wear management of assembly jigs and preventive-maintenance cycles must be finalized from the initial design stage to prevent ECOs (engineering change orders). Production at the Georgia plant suggests the possibility of expanding local North American assembly lines, which would also require domestic equipment makers to have a response system for overseas relocation, installation, and commissioning.

One-Line Summary
The SK On–Neovolta Power 18 GWh partnership is not a one-off order but a five-year repeat-production framework, making assembly-equipment standardization the key response task.
