Enerpoly develops and manufactures zinc-ion batteries to deliver breakthrough affordability in stationary storage. The patented technology innovates on the rechargeability of the single-use zinc-manganese dioxide alkaline battery – a chemistry that has dominated the primary battery industry as a simple, well-performing, economical solution for more than half a century.

Zinc-ion batteries utilize cost-effective, non-critical materials that are available globally and can be recycled in today’s infrastructure. Enerpoly can thus deliver the lowest cost of ownership in battery energy storage and be sustainably scaled. By innovating with these materials, Enerpoly batteries can mitigate 80% of carbon emissions in today’s battery manufacturing.

Founded in 2018, Enerpoly is located at Stockholm, and brings the best of Swedish design and sustainability to the energy storage industry. Enerpoly has raised €4.0M in funding, filed 2 patents with 10+ innovations in the pipeline, built a 100kWh/yr production validation line, tested commercial prototypes of zinc-ion battery cell for UL9540A standards and has 6 pilots planned in 2023.
