Lithium‐sulfur (Li‐S) batteries contain various NMR‐active nuclear isotopes, including 7Li, 6Li and 33S, which are sensitive to the different chemical reactions that occur during battery cycling. Herein, we use a combination of lithium and sulfur operando NMR spectroscopy to provide new insights at the molecular level, fundamental understanding being ...

A hierarchically structured CNT@Co–N–CNF (CCNC) interlayer, made by electrospinning and ZIF‐67‐derived carbonization, synergistically confines lithium polysulfides via a conductive CNT network, N‐doping, and cobalt sites. The optimized 50‐CCNC delivers 1137.4 mAh g − 1 in coin cells and enables pouch cells with 1140.7 mAh and 92.46% retention after 40 ...

A contra‐diffusion strategy is introduced to grow uniformly distributed Co–Nx single‐atom catalysts (CoSAs) within a carbonized aramid nanofiber (CANF) interlayer. The resulting CD‐CANF enables efficient polysulfide regulation, low metal loading, and exceptional long‐term cycling stability in lithium–sulfur batteries. ABSTRACT Achieving durable lithium–

This study synthesizes monodisperse oxide nanoparticles with abundant ionic vacancies encapsulated in 2D porous carbon sheets via pyrolysis of a high‐entropy precursor, constructing a cross‐scale catalytic interface. It enables Li‐S batteries with a high capacity of 761 mAh g−1 at 3 C and retains 80.44% capacity after 1000 cycles at 1 C.
