NETL investigating researching chemistries for large-scale battery- and supercapacitor-based grid energy storage systems

Green Car Congress

Proper design and architecture could lead to Mg-based batteries with energy densities of 400 - 1100 watt hour per kilogram (Wh/kg) for an open circuit voltage in the range of 0.8 - 2.1 volts, which would make it an attractive candidate for electrical grid energy storage and for stationary back-up energy, NETL says.
