A new battery developed by Aquion Energy in Pittsburgh uses simple chemistry—a water-based electrolyte and abundant materials such as sodium and manganese—and is expected to cost $300 for a kilowatt-hour of storage capacity, less than a third of what it would cost to use lithium-ion batteries. Third-party tests have shown that Aquion's battery can last for over 5,000 charge-discharge cycles and has an efficiency of over 85 percent.Once the storage problem is solved, renewable energy sources will make a lot more economic sense. This particular technology is very suitable for off-grid solutions needed in the developing world.
The company has now received $30 million in venture capital to step up manufacturing of its sodium-ion batteries.
