What Aesir Technologies does

Aesir Technologies, Inc. is a privately held Delaware corporation founded in 2011 (formerly known as ZAF Energy Systems) that develops and commercializes Nickel-Zinc (NiZn) and Lithium-Zinc (LiZn) rechargeable battery technologies using sustainable, non-toxic, fully recyclable materials. The company is headquartered in Joplin, Missouri with an R&D facility in Bozeman, Montana, and operates a wholly-owned subsidiary, Battery Grade Materials, which produces nickel hydroxide and battery recycling inputs. Aesir's product portfolio comprises three core platforms: NiZn Prismatic Group 31 batteries for trucking, marine, telecom, data center UPS, and industrial storage (74 Wh/kg specific energy, 144 Wh/L energy density, 600+ cycles at 80% DOD); a patented NiZn Pouch cell design reaching up to 100 Wh/kg for medical and portable electronics; and the Lithium-Zinc Rechargeable Aqueous Hybrid Battery (ReHAB) for stationary energy storage, with claims of 3x cycle life and 2x energy density versus lead-acid without thermal-runaway risk.

Aesir's business model is enterprise hardware sales with a multi-year contract cadence, custom-quoted per application rather than published list pricing. The go-to-market is direct field sales targeting four primary verticals: U.S. defense (U.S. Navy submarine programs across Columbia, Ohio, and Virginia class vessels, plus Air Force and Army energy storage), critical infrastructure (data center UPS, 5G telecom backup), aerospace (general aviation and commercial aircraft STC programs targeting Cessna Citation and Boeing 737 fleets), and trucking/marine industrial applications. Revenue is supplemented by government non-dilutive funding, including an $848,000 NSF Phase II SBIR grant for Lithium-Zinc development and Firm-Fixed-Price defense contracts through BlueForge Alliance. The company holds UL1989 and UL94V2 certifications, has 25+ patents in prosecution (10 granted), and is building a vertically integrated supply chain via partnerships with Eramen Minerals (Philippines), Vedanta Nico (India), and Celgard (separators), supported by a $100 million-financed gigafactory in Rapid City, South Dakota and a planned 1.5 GWh facility in Manila.

Core offering

Æsir Technologies develops, manufactures, and sells rechargeable Nickel-Zinc (NiZn) and Lithium-Zinc (ReHAB) batteries for mission-critical industrial customers. Its product portfolio includes NiZn Prismatic Group 31 batteries for data center UPS, trucking, marine, and telecom backup; NiZn Pouch cells for medical, portable electronics, and other flexible-format applications; and Lithium-Zinc ReHAB cells for stationary energy storage. All products use sustainable, non-toxic, fully recyclable materials and are positioned as a safer, lower-cost alternative to lithium-ion and a higher-performance replacement for lead-acid.

Product overview

Æsir Technologies offers a portfolio of advanced rechargeable battery technologies centered on Nickel-Zinc (NiZn) and Lithium-Zinc chemistries. The core product line consists of three battery form factors: NiZn Prismatic (Group 31) batteries for industrial applications including data centers, trucking, marine, and telecom; NiZn Pouch cells providing flexible, lightweight power solutions for diverse voltage and capacity requirements; and Lithium-Zinc (ReHAB) batteries combining zinc and lithium-ion electrodes for superior cycle life and safety in stationary storage applications. All products utilize sustainable, non-toxic, fully recyclable materials and are designed to outperform lead-acid while avoiding the safety concerns and costs of lithium-ion.
