While at Stockholm University, Dr. Mylad Chamoun had a research breakthrough into the 60-year-old problem of zinc-manganese dioxide battery rechargeability. In 2018, Enerpoly was founded upon this research to build a future where everyone has access to low-cost clean energy through our safe and scalable energy storage solution.

Our batteries resolve the intermittency of renewables and make a grid powered by clean energy viable. Additionally, our technology is affordable, has end-of-life options in society and is made of non-volatile, non-toxic, abundantly available, and accessible materials. This allows us to fully source and develop in Europe, avoiding supply chain instability. Today, funded by the EU and partnered with companies like Polarium, we work to bring the Enerpoly battery to a global scale.
