World's First Zinc-Ion Battery Megafactory Opens For Business

04/09/2024 10:00 // Slashdot

Sweden's Enerpoly has opened the world's first zinc-ion battery megafactory near Stockholm, aiming for a 100 MWh annual capacity by 2026. "According to Enerpoly, this megafactory will serve Europe's needs for safe energy storage, and also utilize an all-European supply chain to boot," reports New Atlas. From the report: If you're wondering why Enerpoly is bothering with zinc-ion and not lithium-ion batteries, it's because the former is a better choice for storage in several ways: - They use a water-based electrolyte, which makes them non-flammable, and reduces the risk of fires and explosions. - They're less expensive, because zinc is far more abundant than lithium (which is difficult and expensive to extract), and easier to handle. They can also operate across a wider temperature range and require less maintenance, making them cheaper than lithium-ion options. - They're more eco-friendly for the same reason. In contrast, extracting lithium currently requires extensive mining as well as the use of massive evaporation ponds before processing even begins. - They're said to last a whole lot longer. According to the International Zinc Association, a nonprofit trade association which counts Enerpoly as a member, zinc-based batteries can last up to 20 years, while lithium batteries manage about 12 years. The downside? They have a lower energy density than something like a Tesla 4680 battery, making them ideal for applications like load shifting and grid resilience.
