N‐Doping Activated Presodiation Enhances Sodium‐Ion Provision in Hard Carbon Anodes

Advanced Science, EarlyView.
Introducing pyrrolic‐N sites enables efficient presodiation and stronger PF6− capture, thus pre ‐ forming a robust inorganic‐rich SEI layer in hard carbon anodes. ABSTRACT Hard carbon (HC) is considered the most promising anode material for commercial sodium‐ion batteries (SIBs), yet it still faces critical challenges such as low initial Coulombic ...

Rational Design of Weakly‐Solvating Molecules for Salt‐In‐Pre‐Ionic‐Liquid Electrolytes for Li Metal Batteries

Advanced Science, EarlyView.
The weakly‐solvating TFMSPyr electrolyte tailors the Li+ solvation structure by suppressing solvent coordination and promoting anion‐dominated solvation. This unique solvation environment induces preferential anion decomposition at electrode interfaces, forming robust inorganic rich S/CEI.

Deciphering the Dynamic Balance Between Solvation Strength and Polysulfides Reaction Heterogeneity in Practical Lithium‐Sulfur Batteries

Advanced Science, EarlyView.
A weakly solvating fluorinated cosolvent (1200ET) enables precise solvation‐power regulation in Li–S batteries, decoupling interfacial stabilization from sulfur redox kinetics. This approach suppresses polysulfide dissolution while preserving reaction kinetics, leading to a stable Li metal interface and high‐energy multilayer pouch cells, revealing a ...

Mn‐Induced Support Stabilization and Ir Electronic Activation Enable Acid‐Stable, Low‐Loading IrO2 Water Oxidation

Advanced Science, EarlyView.
This study introduces a dual‐regulation strategy utilizing a Mn‐doped Co3O4 support to enhance the activity and stability of low‐loading IrO2 catalysts for acidic water oxidation. Mn induces strong Mn─O covalency to reinforce the spinel lattice and activates Ir sites via interfacial electron transfer.

Tailoring Multifunctional Carbon Dots via Precursor Stoichiometry: Switching Between Solid‐State Fluorescence and Broadband Absorption Through Aggregation Control

Advanced Science, EarlyView.
Precursor stoichiometry programs the surface chemistry of carbon dots, directing their self‐assembly into distinct aggregation modes. Aldehyde‐enriched surfaces form ordered, hydrogen‐bonded assemblies that enable bright red solid‐state fluorescence, whereas amine‐rich surfaces promote compact π–π stacked aggregates with broadband visible‐light ...

Impurity Tolerance in LiFePO4 Cathodes: Contrasting Structural, Electronic, and Electrochemical Roles of Residual Ni and Cr

Advanced Science, EarlyView.
Impurity tolerance in LiFePO4 cathodes varies strongly with impurity type and content. Low Ni levels are accommodated within the lattice with minimal structural disruption, whereas higher Ni contents introduce antisite disorder. In contrast, Cr impurities segregate from the LiFePO4 framework, blocking lithium‐ion pathways and leading to inferior ...
