Startup Aquion Energy shows off the next generation of its battery for solar, the grid

Gigaom

Battery startup Aquion Energy has unveiled the second generation of its low-cost battery that the company’s customers can plug into solar systems and the power grid. On Tuesday at the Solar Power International conference in Las Vegas, Aquion announced that its new battery can deliver up to 40 percent more energy for customers’ needs, but in the same boxy size and shape.

The seven-year-old company, based in West Pennsylvania, says it made these gains through core battery chemistry, and more efficient use of the battery’s active materials. Aquion makes a battery from a combination of non-toxic materials including salt water, carbon and manganese oxide. The original technology was invented by Carnegie Mellon Professor Jay Whitacre, Aquion Energy’s founder and CTO, and funded early on by venture capital firm Kleiner Perkins.
