Porphyrin Organic Frameworks: Porphyrin Organic Framework Hollow Spheres and Their Applications in Lithium–Sulfur Batteries (Adv. Mater. 23/2018)

In article number 1707483, Qiang Zhang and co-workers design and prepare porphyrin organic framework hollow spheres with well-defined chemical structures of the organic frameworks. The as-obtained hollow spheres serve as a desirable host for the sulfur cathode in lithium–sulfur batteries, enabling high capacity, long-term stability, and excellent rate performance.
