Aquion Energy says its sodium-ion battery technology can solve these problems. The Pittsburgh, Pa.-based startup says its technology can deliver round-trip energy efficiency of 85 percent, a ten-year, 5,000-plus-cycle lifespan, energy storage capacity optimized to charge and discharge for multi-hour applications, and perhaps most notably, a price point of $250 per kilowatt-hour -- much lower than the $500-and-up per kilowatt-hour of today’s competing technologies.

Amprius, a startup working on a new type of long-lasting lithium-ion batteries for laptops and electric vehicles, has started to sell its batteries for use in portable electronics. The company recently raised $30 million in venture capital to develop its next-generation batteries, which use high-energy silicon electrodes. The company says the batteries will store about 50 percent more energy than the battery cells in today’s electric vehicles.
