The zinc-ion battery research started in 2016 thanks to the financial support by the Swedish Energy Agency. After more than one year of development and support by industrial partners, we achieved major R&D breakthroughs in 2017. Proceeding with our development, we achieved our first successful zinc-ion cell prototype in 2018. From this, Enerpoly AB was founded with the goal of revolutionizing stationary energy storage by innovating in critical battery components. We are now preparing ourselves for pre-commercialization, on the one hand continuing with R&D, on the other hand build commercial cells.
