Energy storage, clean and simple.
Introducing the first safe and sustainable battery.
Our unique Aqueous Hybrid Ion (AHI™) chemistry is made from abundant, nontoxic materials. Our batteries contain no heavy metals or toxic chemicals and are non-flammable and non-explosive, making them the cleanest and safest batteries for your home or business. Our Aspen battery series is the first and only in the world to be Cradle to Cradle Certified™, an esteemed quality mark for products made from sustainable materials and manufacturing processes.
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.
Aqueous Hybrid Ion (AHI) Chemistry
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.
