Enerpoly’s Production Innovation Center (EPIC) in Stockholm is pioneering the safest and most sustainable zinc-ion batteries for reliable energy storage. With cutting-edge manufacturing and a fully European supply chain, we’re setting new standards in clean energy storage to power a resilient future.
Harnessing renewable energy like solar and wind is essential for a resilient energy future, but their intermittent nature requires reliable energy storage to ensure power availability at all times. Beyond balancing renewables, energy storage has become a critical component of infrastructure, enhancing grid flexibility and efficiency by delivering stored electricity during peak demand or disruptions to prevent outages. It also supports a decentralized grid, enabling distributed energy systems to operate independently and ensuring energy security for remote and disaster-prone areas. Moreover, energy storage accelerates electrification, reducing dependence on fossil fuels and costly peak plants1 while potentially lowering customer bills, in some cases by 15-20%2. Enerpoly is at the forefront of developing advanced energy storage technology to address current grid challenges and build the renewable energy infrastructure necessary for a sustainable future.
The Enerpoly Production Innovation Center (EPIC) is the world’s first megafactory dedicated to zinc-ion battery manufacturing. Located in Stockholm, Sweden, and utilizing 100% European supply chains, this facility represents a major leap forward in delivering the most sustainable and cost-effective batteries for energy storage. It also serves as a demonstration for high-volume production of zinc-ion batteries while pioneering advancements in the manufacturing process, laying the foundations for Enerpoly’s future zinc-ion gigafactory production plans.
In 2024, Enerpoly opened EPIC at a pivotal moment, as technology innovation converged with business maturity and market demand. The growing demand for energy storage solutions that can economically and safely bridge the gap between short- and long-duration applications presented a favorable environment for scaling up production. This demand is largely driven by the increasing need for enhanced renewable energy integration3 and greater resilience in energy supply.
Moreover, the evolving geopolitical and regulatory landscape is becoming increasingly supportive of energy storage technologies. As awareness of energy storage's crucial role in climate goals and energy security grows, governments are developing policies to facilitate the deployment of energy storage technologies. For instance, the European Association for Storage of Energy (EASE) highlights the necessity of deploying energy storage to enable a cost-effective energy transition4. EPIC was launched with financing secured from the Swedish Energy Agency, recognizing that the project supports the aforementioned goals, contributes to the EU's 2050 climate neutrality objective, and reinforces Sweden's leadership in the energy transition.
As the energy storage market continues to expand, Enerpoly is well-poised to contribute to a sustainable energy future with a commitment to build a future where everyone has access to clean energy. Our energy storage solutions prioritize sustainability and safety while remaining cost-competitive, making zinc-ion batteries affordable today and positioning them as the most economical solution for the future.

It is well known that the challenges inherent in complex manufacturing environments can lead to decreased productivity, inefficiencies, quality issues, and increased costs, all of which significantly impact production output and hinder business growth. At Enerpoly, we have prioritized leveraging and optimizing existing manufacturing technologies, and in 2024, we acquired equipment that has been proven in lithium-ion and nickel-metal hydride production. Our innovative approach to minimizing complexity in both production and product design, combined with the inherent safe nature of zinc-ion chemistry, has allowed us to create a simpler manufacturing environment that supports effective scaling.
In production, Enerpoly has significantly streamlined the manufacturing process for zinc-ion batteries compared to what is required for lithium-ion battery production, including the shortening of steps like formation times. This approach reduces risks in the manufacturing process and boosts productivity. Additionally, zinc-ion manufacturing has minimal production constraints—such as not requiring clean or dry rooms due to the safe nature of zinc-ion chemistry—which reduces energy consumption and operational costs.
Enerpoly has transitioned from producing individual battery cells to battery cell modules, simplifying the integration of cells into battery packs and making the overall assembly process more efficient. Creating the electrodes—one of the most challenging and complex aspects of battery manufacturing due to factors like maintaining stringent quality control and ensuring consistent quality across larger volumes—is straightforward and efficient in our design. This emphasis on simplicity results in more consistent and efficient production, with shorter lead times.
Enerpoly’s innovative dry electrode manufacturing process for zinc-ion batteries is setting a new industry standard and encouraging other battery manufacturers to adopt this method due to its lower energy consumption and reduced environmental footprint5. This approach not only offers significant economic advantages but also facilitates the production of high-energy-density electrodes6.
In contrast, traditional wet, slurry-based electrode processes are energy-intensive and environmentally burdensome, requiring liquid slurries that must be dried and managed through complex solvent systems. Moreover, these solvents can be toxic, which is harmful to workers and requires careful disposal processes. Our dry electrode technology addresses these challenges by utilizing dry materials, which eliminate the drying phase and results in substantial energy savings.
The key benefits of our process include:
In today’s market, the battery supply chain for materials is heavily concentrated, with nearly 90% of global installed cathode active material manufacturing capacity and over 97% of anode active material manufacturing capacity for lithium-ion batteries being sourced from a single region7. This is similar for manufacturing equipment sourcing as well. Enerpoly stands out by sourcing 100% of our materials and manufacturing equipment from Europe. This collaboration with European industry not only insulates Enerpoly from potential supply chain instability, but also leverages the innovation and quality standards for which the region is known.
Enerpolys approach to industrial-scale production is built on a strong foundation of technology and talent. We have developed our own patented zinc-ion battery technology, with the inventors actively involved in our operations. Our team brings over a decade of experience in battery manufacturing, along with a strong drive and commitment to innovation and sustainability.
At Enerpoly, we are determined to reduce the cost of energy storage to below USD 50 per kilowatt-hour (kWh) within the next five years while achieving 70% lower CO2 emissions compared to other options on the market. This is made possible thanks to the raw materials we use and our leverage of existing, mature recycling infrastructure. This milestone could result in a reduction of global carbon emissions by 50 megatons (Mt) of CO2 equivalent over the next decade. By delivering the world’s safest, most sustainable, and most cost-effective energy storage solutions, we are transforming the stationary energy storage market and accelerating the transition to a cleaner, greener future.
