e-Zinc

e-Zinc is an energy storage technology company that develops rechargeable zinc batteries as a long-duration energy storage solution. The company technology uses zinc-air electrochemistry to store energy for extended periods, offering a cost-effective alternative to lithium-ion batteries for grid-scale energy storage applications. e-Zinc batteries are designed to store renewable energy for 10 to 100 hours, addressing the intermittency challenges of solar and wind power by enabling energy storage that bridges gaps in renewable generation. The technology uses abundant, low-cost zinc materials, avoiding the supply chain constraints and safety concerns associated with lithium-ion batteries while providing the long-duration storage capabilities needed for grid decarbonization. Founded in 2012 and headquartered in Toronto, Canada, e-Zinc has raised $61.8 million in Series A funding from investors including Anzu Partners, BDC Capital Management, Toyota Ventures, and Energy Foundation.
