NeoVolta Power has secured a major supply agreement with SK On to fuel the expansion of its US battery manufacturing operations. The deal, announced recently, will see SK On provide NeoVolta with 9 gigawatt-hours (GWh) of lithium iron phosphate (LFP) battery cells from 2027 through 2031. These cells are destined for NeoVolta’s factory in Pendergrass, Georgia, where they will be assembled into battery energy storage systems for commercial and utility-scale projects.
This partnership marks a significant milestone for both companies and the US energy storage sector. SK On, headquartered in Seoul, will become the primary cell supplier for NeoVolta’s LFP pouch-cell products. The agreement is structured in two parts, with the first 9 GWh commitment fully signed. A second, conditional framework exists for an additional 9 GWh of cells, which could be used by NeoVolta to build packs sold back to SK On.
The total potential collaboration could reach 18 GWh over the five-year period, though the second phase depends on future orders and terms. NeoVolta CEO Ardes Johnson emphasized that the deal secures long-term access to US-made cells, supporting the company’s expansion into large-scale energy storage. This move aligns with NeoVolta’s strategy to build a domestic manufacturing platform amid growing demand for reliable battery systems.
NeoVolta launched its US manufacturing platform in January, with the Georgia plant’s first line designed for 2 GWh of annual output. The SK On supply could enable a second production line, potentially raising the factory’s capacity to 8 GWh by 2028. LFP chemistry is favored for stationary storage due to its long cycle life, thermal stability, and absence of nickel or cobalt, despite being less energy-dense than other lithium-ion types.
The agreement comes as the US battery storage market sees rapid expansion, with a record 20.2 GWh added in a single recent quarter. Industry observers view such supply deals as critical for meeting surging demand while bolstering domestic production capabilities. The partnership between NeoVolta and SK On could serve as a model for future collaborations aimed at scaling US-based energy storage manufacturing.
