ElevenEs

ElevenEs is a Serbian battery company that describes itself as Europe's leading producer of lithium iron phosphate (LFP) prismatic blade cells and packs. Founded in 2019, the company set out to build battery cell production in Europe around LFP chemistry, a cobalt- and nickel-free technology that it positions as safer, longer-lasting and more affordable than conventional lithium-ion chemistries. Its stated purpose is to make clean energy storage accessible to people, industries and communities. The company operates an LFP research and development center that has been running since 2021, where its team develops custom cell assembly and analysis. In 2022 ElevenEs reported producing the first full-size LFP battery in Europe after testing hundreds of chemistries, and in 2023 it opened its first European LFP production facility to supply customers with EDGE cells for A and B sample testing. By 2024 it was delivering LFP cell samples to electric vehicle and energy storage system manufacturers. ElevenEs sells a family of LFP cells under the EDGE brand, including the Edge135, Edge148, Edge152 and Edge600 blade cells, aimed at applications ranging from AI server farms and uninterruptible power supplies to electric vehicles, heavy-duty mobility and grid-scale energy storage. It also offers the EdgeBloq series of battery energy storage system (BESS) products and the EdgeRaq800, and provides battery testing and validation services through its EdgeLabs offering, letting external partners test materials in real blade cells. The company's roadmap centers on a planned megafactory. According to its published plan, construction of the megafactory was to begin in 2026, with a first 1 GWh production phase starting in 2027. ElevenEs frames its business around European supply-chain resilience, arguing that geopolitical conflict and the weaponization of trade chokepoints are accelerating a pivot toward LFP because it avoids dependence on nickel and cobalt. It is a private company and remains focused on the European market.

ElevenEs was founded in 2019, when, according to the company's own account, a vision was sparked by its founder and CEO to revolutionize battery cell production in Europe using LFP chemistry. The company is based in Serbia and set out to build a European alternative to the dominant Asian supply of lithium-ion cells, focusing on lithium iron phosphate rather than nickel- and cobalt-based chemistries. In 2021 ElevenEs opened what it describes as the first European LFP research and development center. That facility has been operational since 2021, with an expert team developing custom cell assembly and analysis. The R&D work involved testing more than 500 different chemistries, and in 2022 the company reported producing the first full-size LFP battery in Europe. In 2023 ElevenEs opened its first European LFP production facility, intended to supply customers with EDGE battery cells for A and B sample testing. In 2024 the company delivered LFP cell samples to electric vehicle and energy storage system manufacturers, moving from laboratory development toward customer qualification. By the mid-2020s ElevenEs had built out a product family of LFP prismatic blade cells under the EDGE name, including the Edge135, Edge148, Edge152 and Edge600, and had extended into complete storage products with the EdgeBloq series and EdgeRaq800. It also launched EdgeLabs, a testing and validation service that lets external partners test battery materials in real blade cells without building their own pilot facilities. Looking ahead, ElevenEs has published a plan for the next decade centered on a megafactory. Construction of the megafactory was scheduled to begin in 2026, with a first 1 GWh production phase starting in 2027. The company frames this expansion in terms of European supply-chain resilience, arguing in a 2026 article that global conflict has turned batteries from commercial components into strategic national assets and is accelerating the shift toward LFP because it avoids reliance on nickel concentrated in Russia and cobalt affected by instability in Africa.
