A Dispersant‐Driven Carbon‐Binder Domains Homogeneity in High‐Energy‐Density Electrodes for Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A polar dispersant, aromatic‐functionalized polyacrylate (AFPA), enables the formation of a uniform CBD network by enhancing miscibility with PVDF and suppressing phase separation. This leads to α‐phase crystallization of PVDF and aligned CNT networks within the CBD, resulting in well‐connected structures that improve cohesion, electron/ion transport ...

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

open access: yesAdvanced 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

ZrCo3B2 and HfCo3B2 Electrodes Go on Stage for Oxygen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
The intermetallic compounds ZrCo3B2 and HfCo3B2 with distinctive chemical bonding features are excellent OER precursors, restructuring into OER‐active electrocatalysts delivering significantly high OER activities compared to the elemental Co, which is obvious from their lower onset potentials and increased obtained current densities.

Disentangling Elemental Roles in an Amorphous Medium‐Entropy Electrocatalyst for Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
An amorphous medium‐entropy FeCoNiMo‐a catalyst with a unique nanoring architecture is synthesized via a solvothermal method. The catalyst exhibits exceptional stability in anion exchange membrane water electrolysis, maintaining stable operation for over 600 h at 1 A cm−2.
