Bidirectional Soft Catalysts for Improved Power Performance of Li‐S Batteries

Advanced Science, EarlyView.
A soft polymer‐metal catalyst is integrated into the binder to create a catalytically active microenvironment that accelerates bidirectional sulfur redox kinetics in lithium‐sulfur batteries. A model polyvinyl alcohol‐Cu catalyst enables high areal capacities at demanding current densities and stable cycling in pouch‐cell prototypes at 0.5 C, achieving

Reducing Ion Transport Friction by Mitigated Diluent‐Solvent Interaction for Sodium–Sulfur Battery

Advanced Science, EarlyView.
A local high‐concentration electrolyte to balance the ionic conductivity and interfacial stability is developed through replacing the high solvating DME with the moderate solvating diethyl ether to mitigate the diluent‐solvent interaction and reduce the local dynamic friction for Na+ transport, while maintaining the anion‐rich solvation clusters and ...

Visualizing a Li‐Depleted Amorphous Cathode–Electrolyte Interphase in Sulfide Solid‐State Batteries Using In Situ Cryogenic Electron Microscopy

Advanced Science, EarlyView.
In situ cryogenic STEM‐EELS and electron diffraction directly visualize Li depletion and structural degradation at the NCM523/Li6PS5Cl interface during charging. The results reveal a Li‐depleted amorphous interphase that impedes Li transport, while LiNbOy coating suppresses interfacial degradation and preserves the solid‐electrolyte structure ...
