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.
