Researchers propose reason for capacity loss in metal-oxide battery materials

Green Car Congress

Because of their high energy-storage density, materials such as metal oxides, sulfides, and fluorides are promising electrode materials for lithium-ion batteries in electric vehicles and other technologies. Magnetite, among other conversion-type electrode materials (i.e., However, their capacity fades very rapidly.

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

Green Car Congress

This includes research on appropriate anodes, cathodes, and electrolytes for magnesium (Mg)-, sodium (Na)-, and lithium (Li)-based batteries and novel transition metal oxide- and nitride-based supercapacitor electrode materials. Magnesium is much more abundant in the Earth’s crust, making it less expensive than Li by a factor of 24.
