A Multifunctional Secondary Based on Heterogeneous Co‐MnO@NC for Depth‐Induced Deposition and Conversion of Polysulfides in Li─S Batteries

is observed after 200 cycles at 0.2 C, showing good further practical reliability. This work demonstrates the advancement application of Co-MnO@NC bimetallic heterojunctions catalysts in the secondary current collector for high-performance Li─S batteries, thereby providing guidance for the development of interlayer in various dissolution systems.
