Strings of Porous Carbon Polyhedrons as Self‐Standing Cathode Host for High‐Energy‐Density Lithium–Sulfur Batteries
Abstract
Rational design of cathode hosts with high electrical conductivity and strong sulfur confinement is a great need for high‐performance lithium–sulfur batteries. Herein, we report a self‐standing, hybrid‐nanostructured cathode host comprised of metal–organic framework (MOF)‐derived porous carbon polyhedrons and carbon nanotubes (CNTs) for the significant improvement of both the electrode cyclability and energy density. The strong coupling of the intertwined CNTs and strung porous carbon polyhedrons as a binder‐free thin film significantly enhances the long‐range electronic conductivity and provides abundant active interfaces as well as robust electrode integrity for sulfur electrochemistry. Attributed to the synergistic combination of the CNTs and carbon polyhedrons, the obtained sulfur electrodes exhibit outstanding cyclability, an excellent high‐rate response up to 10 C, and an ultra‐high volumetric capacity of 960 Ah L−1.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
