Monodisperse High‐Entropy Metal Oxide Nanoparticles Encapsulated Within 2D Porous Carbon Sheets for Enhanced Catalytic Activity in Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
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.
