Non-Hazardous Deep-Cycle Batteries for On or Off the Grid

Aquion offers high-performance “saltwater” energy storage without lead, sulfuric acid, or flammable lithium salts.

For the last 50 years, saltwater batteries have been the stuff of middle school science projects and Gilligan’s Island episodes. Now they might be poised to transform how the grid integrates renewable energy.

Toxic lead–acid batteries have been the industry standard almost since batteries were invented. Meanwhile, expensive lithium-ion batteries are just gaining traction. Aquion is different from both of these.
