A team at Nankai University in China has devised high-performance Li-sulfur battery cathode materials consisting of sulfur nanodots (2 nm average) directly electrodeposited on flexible nickel foam; the cathode materials incorporate no carbon or binder. However, the electrochemical inertness of bulk sulfur in the cathode of Li?S

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.

Researchers at the University of Maryland (UMD), the US Army Research Laboratory (ARL), and Argonne National Laboratory (ANL) have developed a non-flammable fluorinated electrolyte that supports the most aggressive and high-voltage cathodes in a Li-metal battery. Li metal offers one of the highest specific capacities (3,860 mAh g ?1
