Lithium-sulfur batteries use sulfur as the electrode material, which is of great interest for its higher theoretical specific capacity and energy density compared to existing graphite-based lithium-ion batteries. During the discharge process, the S8 molecule gradually acquires electrons to combine with Li+ and undergoes multiple polysulfide intermediates (Li2Sx, x=2, 4, 6, 8) before it is...
