Energy storage, clean and simple.
Introducing the first safe and sustainable deep cycle battery.
Our unique Aqueous Hybrid Ion (AHI™) chemistry is made from abundant, nontoxic materials. Our deep cycle battery technology contains no heavy metals or toxic chemicals and is non-flammable and non-explosive, resulting in the cleanest and safest batteries for your home or business.
AHI chemistry is composed of a saltwater electrolyte, manganese oxide cathode, carbon titanium phosphate composite anode, and synthetic cotton separator. The battery utilizes non-corrosive intercalation reactions at the anode and cathode. See how we compare to lithium ion and lead acid.

How it all started.
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. Aquion’s Aspen batteries are sealed electrochemical energy storage systems based on our unique saltwater electrolyte. Unlike flow batteries, lithium ion batteries, and lead acid batteries, our Aspen batteries are made using abundant, nontoxic materials and modern low cost manufacturing techniques. Our saltwater batteries are maintenance-free and optimized for daily deep cycling.
