Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Ni‐rich cathodes in sulfide‐based ASSBs undergo intertwined (electro)chemical and mechanical degradation. Here, a new diagnostic framework is presented to decouple each contribution by partitioning capacity fading into charge and discharge fading.

Universal Oxychlorination Strategy in Halide Solid Electrolytes for All‐Solid‐State Batteries
A WO2Cl2‐driven oxychlorination strategy enables bulk oxygen incorporation into close‐packed LixMCl6 (M = Zr, Y, Er, In) halide lattices. Oxygen is selectively anchored by W6+ as lattice‐integrated [WO2Cl4]2− units, regulating the anionic framework, diversifying Li coordination, and weakening Li–Cl interactions.

Degradation Pathways of Silicon‐Based Anodes in Lithium‐Ion Batteries
Silicon‐based anodes undergo degradation through five primary pathways: (1) mechanical and structural deterioration of the active material, (2) loss of electrode integrity and electrical contact, (3) mechanical instability of the solid electrolyte interphase (SEI), characterized by repetitive fracture and deformation, (4) chemical instability of the ...

This study develops a novel sparingly solvating electrolyte for potassium–sulfur batteries, utilizing tetrahydrofuran (THF) to induce an anion‐dominated solvation structure that eases polysulfide shuttling and forms an inorganic‐rich solid–electrolyte interphases (SEI). Dimethyl diselenide (DMDSe) accelerates quasi‐solid‐state transformations, reducing

Debunking Common Myths & Misconceptions About NMC Positive Electrode Materials for Li‐ion Batteries
LiNixMnyCozO2 (NMC) and LiNixCoyAlzO2 (NCA) remain the choice for high‐energy‐density lithium‐ion battery positive electrode materials, yet many myths persist surrounding them. Herein, four common misconceptions are tackled to better inform the lithium‐ion battery field.

The role of each Mn site in the Na3‐xMn[Mn(CN)6]·zH2O compounds’ redox activity was investigated using a combined experimental–computational approach, which shows that only the low‐spin Mn‐C site undergoes redox changes (Mn1+ to Mn4+), while high‐spin Mn‐N remains unchanged. The study confirms the presence of the Mn1+ intermediate and newly reveals its
