Sketch of the Sn/C/CGPE/ Li 2 S/C polymer battery. The battery is formed by a Sn/C composite anode, a PEO-based gel polymer electrolyte, and a Li 2 S/C cathode. Lithium-sulfur cells are based on the electrochemical reaction: 16Li + S 8 8Li 2 S. PEO=poly(ethylene oxide). Credit: Hassoun and Scrosati. Click to enlarge.
