Enerpoly has launched the world's first zinc-ion battery megafactory near Stockholm, Sweden, with plans to achieve an annual capacity of 100 MWh by 2026.

The company was founded in 2018 by Dr. Mylad Chamoun and Dr. Samir Nameer, building on breakthrough research in zinc-ion battery chemistry from Stockholm University.

Enerpoly focuses on developing zinc-ion battery cells for grid storage and backup power, targeting applications in renewable energy and enhancing power resiliency.

The megafactory is designed to address Europe's increasing demand for safe energy storage solutions and will utilize an all-European supply chain.

To date, Enerpoly has raised €15.1 million in funding, including significant support from the Swedish Energy Agency, to advance its battery technology.

CEO Eloisa de Castro highlighted that the new facility is vital for driving sustainable innovation and meeting the growing demand for renewable energy storage.

Zinc-ion batteries offer advantages over lithium-ion batteries, such as safety, cost-effectiveness, and environmental benefits, due to their water-based electrolyte and abundance of materials.

Enerpoly has innovated designs to overcome historical challenges with zinc-ion batteries, particularly issues related to recharging and dendrite formation.

The facility, named the Production Innovation Center (EPIC), is set to begin production in 2025, aiming to co-develop market-ready battery solutions for various applications.

Sweden's abundant zinc reserves enable Enerpoly to establish a robust European supply chain for its batteries, enhancing energy resilience in the region.

Enerpoly aims to fill a market gap in energy storage solutions that last between 2 to 10 hours, a range where lithium-ion batteries are less effective.

Zinc-based batteries can last up to 20 years, significantly outlasting lithium batteries, which typically have a lifespan of around 12 years.
