A porous Cu1.82Se@MXene conductive interlayer for room-temperature sodium-sulfur batteries
Room-temperature sodium-sulfur batteries are promising for large-scale energy storage because of the low cost and high abundance of sodium and sulfur, but their practical application is still limited by polysulfide shuttling, sluggish sulfur redox kinetics, and poor long-term stability. In this work, a porous Cu1.82Se@...
