Sweden opens world’s first zinc-ion battery megafactory
Enerpoly in Stockholm has opened the world’s first megafactory for zinc ion battery cells and packs.
The facility will house all of the Enerpoly operations and is expected to operate at full capacity of 100MWh by 2026 with a fully European supply chain for zinc ion battery cells and packs.
Back in July, Enerpoly bought up the cutting-edge dry anode end-to-end battery production line and process development capabilities from local competitor Nilar.
The 6,500m² (70,000ft²) Enerpoly Production Innovation Center (EPIC) facility is in Rosersberg in northern Stockholm and will enable Enerpoly to conduct large-scale pilots targeting commercial, industrial, and utility applications using zinc ion battery technology. Commissioning has already begun and production starts in 2025.
“Our new manufacturing facility marks a pivotal moment in our journey toward revolutionizing the energy industry. With EPIC, our focus is firmly on driving sustainable innovation, and meeting the growing demand for renewable energy storage. By scaling up our production, we can deliver first-of-all-kind deployments in partnership with utilities and battery system integrators across Europe and globally,” said Enerpoly CEO, Eloisa de Castro.
Enerpoly is based on battery chemistry research at Stockholm University with patented battery cell technology to deliver affordable, sustainable and safe zinc-ion batteries for grid or large-scale storage, backup power, and safety-critical applications of energy storage including for maritime use, critical infrastructure and densely populated urban areas.
Dry electrode manufacturing helps to boost the pack assembly process says Enerpoly, The Nilar process used expensive raw materials and so suffered from high commodity prices. Instead Enerpoly is using locally sourced, affordable materials, and will integrate the Nilar machinery to scale its zinc-ion production. Enerpoly has also carefully selected and hired engineering, process development, and operational staff who have led the development and integration of Nilar’s cutting-edge dry electrode manufacturing process.
