Nanofibers Comprising Interconnected Chain‐Like Hollow N‐Doped C Nanocages as 3D Free‐Standing Cathodes for Li–S Batteries with Super‐High Sulfur Content and Lean Electrolyte/Sulfur Ratio (Small Methods 5/2022)

Lithium–Sulfur Batteries In article number 2200049, Rakesh Saroha and Jung Sang Cho prepare free-standing 3D cathode substrates comprising metal-organic framework derived interconnected chain-like hollow N-C nanocages (50 nm), forming a highly porous N-doped carbon framework using electrospinning. The electrochemical performance of practically viable lithium–sulfur batteries with impressive battery parameters such as high effective sulfur content (83.2 wt.%), high active material loading (14.3 mg cm−2), and low electrolyte/sulfur (6.8 μL mg−1) ratio is obtained.
