Our patented Aqueous Hybrid Ion (AHI™) battery technology provides high performance, safe, sustainable, and cost-effective energy storage for long-duration stationary applications.


Energy Storage,
Clean and Simple.

Our technology is based on a simple idea: In order to meet the challenges of the world’s growing energy needs and increase the use of renewable power, we need large-scale energy storage systems that are high performance, safe, sustainable and cost-effective. Our founder, Professor Jay Whitacre, set out to solve this problem and discovered a simple and elegant solution that is a twist on a 200 year-old technology: saltwater batteries. Aquion developed this solution into our patented Aqueous Hybrid Ion (AHI™) chemistry, a unique saltwater electrolyte battery technology. Using abundant, nontoxic materials and modern low cost manufacturing techniques, our AHI batteries are now ready to take on the global energy storage challenge.


Unmatched Performance

Aquion’s battery technology offers thousands of real-use application cycles for long duration (4 to 20 hour) applications. The batteries are extremely tolerant to abuse with the ability to stand at a partial state of charge with minimal degradation. The system requires no costly thermal management or regular maintenance and contains no hazardous materials, corrosive acids, or noxious fumes.

A Unique Chemistry

Our unique Aqueous Hybrid Ion (AHI) chemistry is composed of a saltwater electrolyte, manganese oxide cathode, carbon composite anode, and synthetic cotton separator. The battery utilizes non-corrosive reactions at the anode and cathode to prevent deterioration of the materials. The water-based chemistry results in a nontoxic and non-combustible product that is safe to handle and environmentally friendly.


Enabling New Possibilities

Aquion’s AHI batteries are the much-needed solution for stationary, long-duration, daily cycling applications. Designed to meet the needs of existing and emerging storage applications, AHI batteries enable new possibilities for off-grid, microgrid, energy management, and grid service applications.
