A High‐Performance Polymer Tin Sulfur Lithium Ion Battery

Abstract

The lithium–sulfur battery, based on the electrochemical reaction 16 Li+S8Q8Li2S, has a theoretical specific energy and energy density of 2500Whkg-1 and 2800WhL-1, respectively, much greater than those of any conventional lithium battery. The Li–S battery has been investigated by many workers for several decades; however, such studies have been limited to the simplest cell configuration consisting of sulfur as the positive electrode, lithium metal as the negative electrode, and a solution of a lithium salt in an aprotic organic solvent as the electrolyte.
