The commercial application of lithium-sulfur batteries is severely hampered by polysulfide shuttle effects, sluggish redox kinetics, and uncontrollable lithium dendrite growth. Herein, a unique Ni-doped CoSe2 nanoparticle decorated bilayer carbon (Ni-CoSe2/BC) structure is synthesized for both the s...
