Cycling performance of Li/SeS 2 ?C, Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6
