Co-NC/Nb2O5 heterostructure enable the synergistic fast sulfur redox kinetics and uniform lithium deposition for advanced lithium sulfur batteries
{{output}}
Lithium‑sulfur batteries (LSBs) have attracted much attention due to their high theoretical energy density (2600 Wh kg-1) and low cost of sulfur cathodes. However, their practical application is hindered by the significant polysulfide shuttle effect and slugg... ...
