Enerpoly, a Stockholm-based company specializing in zinc-ion battery cell technology, has inaugurated the world’s first zinc-ion battery megafactory in Rosersberg, north of Stockholm. The Enerpoly Production Innovation Center (EPIC) covers an area of 6,500 square meters and is expected to reach an annual production capacity of 100 MWh by 2026.
The commissioning of the megafactory has started and production is expected to start in 2025. EPIC will facilitate the co-development of market-ready battery solutions with customers and enable large-scale pilot projects for commercial, industrial and utility applications.
This development follows Enerpoly’s acquisition of advanced dry electrode manufacturing equipment in July 2024. The company now has end-to-end battery production line and process development capabilities that are expected to increase production efficiency, reduce costs and waste, and improve the sustainability of its energy storage solutions.
The establishment of EPIC, combined with Enerpoly’s European supply chain, represents a significant step in the development of zinc-ion technology in Europe. It also strengthens Sweden’s position in clean energy innovation and lays the foundation for Enerpoly’s future zinc-ion gigafactory production plans.
Enerpoly’s zinc-ion batteries are designed for various applications, including grid or large-scale storage, backup power, and safety-critical applications such as maritime operations, critical infrastructure, and densely populated urban areas. The company uses European equipment and readily available raw materials such as zinc and manganese to create a local supply chain, contributing to a more diverse and resilient European energy sector.
Founded in 2018, Enerpoly has secured €15.1 million in funding to date. The company aims to support the global transition to renewable energy through its zinc-ion battery technology.
The development of Enerpoly’s zinc-ion battery megafactory aligns with industry efforts to meet the COP28 goal of tripling global renewable energy capacity by 2030, and addresses the projected significant increase in energy storage needs.
