 New Proprietary Ceramic Material for Deep-Cycle Sodium Batteries Published: Nov 13, 09 Comments: 4 Views: 854 A new ceramic material dubbed NaSICON (sodium - Na - super ion conductor) may make widly distributed, home-based battery power storage charged by solar and wind power possible. Ceramatec, the R&D arm of CoorsTek, based in Salt Lake City, Utah, has made a massive breakthrough in deep-cycle storage batteries. The deep-cycle storage battery prototype is made of common materials, safely operates at room temperature, and can supply household power at about $0.025/kWh compared to the current average of $0.08/kWh for grid-tied power. The units should be available in 2015, sell for about $2K and last for 10 years.  In a laboratory at Ceramatec, a small battery -- a NaSICON sandwich in silver foil -- has been cycling up and down since October to prove out the electrochemistry. Engineers are confident the tests will support a projected useful life of 3,650 cycles, which meet the standard of one discharge/recharge cycle per day for 10 years. It's a tall challenge, according to Coors, but doable. "It's very efficient in terms of watt-hours per kilogram," he said.
