Web1 Introduction. Lithium–sulfur batteries (LSBs) have the potential for >400 miles driving range with practical capacities up to 500 Wh kg −1 (twice that of Li-ion batteries or LIBs) at the pack level. [1-3] In conventional LSBs, the cathode consists of insulating sulfur embedded into a conducting host, while a thin Li metal strip serves as the anode with a … WebSome metals crystallize in an arrangement that has a cubic unit cell with atoms at all of the corners and an atom in the center, as shown in [link]. This is called a body-centered cubic (BCC) solid. Atoms in the corners of a BCC unit cell do not contact each other but contact the atom in the center.
