The cover feature showcases a high-performance Li-S battery electrode made from an N-doped 3D carbon-nanoweb structure, synthesized in a single step from polypyrrole. This innovative 3D carbon structure enhances electrochemical performance by improving electrical conductivity and facilitating the mass transfer of the liquid electrolyte through its efficient porous structure. This uniquely engineered electrode system offers a promising new direction for the practical application of high-performance Li-S batteries.
