Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
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.

Electrolyte Covalent Organic Frameworks for Exceptional Potassium Ion Conduction

Angewandte Chemie, EarlyView.
One‐pot polymerization of monomers with oligo(ethylene oxide) side chains of different lengths creates electrolyte covalent organic frameworks with well‐defined K+‐electrolyte pathways in 1D pores for K+ conduction. The materials promote K+ conduction exponentially with the side chain length, achieve exceptional conductivity, and enable frictionless ...

Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

Advanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.

One‐Step Radical‐Intensified Selective Etching (RISE) Strategy for High‐Yield Synthesis of Monolayer MXene with Tailored Nanoholes

Angewandte Chemie, EarlyView.
Radical‐intensified selective etching (RISE) delivers monolayer MXenes with >80% yield in just 3 h etching process. Controlled ·OH dosage enables one‐step access to holey MXenes with abundant nanopores or defect‐lean flakes. This mild, safe strategy couple ultrafast kinetics with structural tunability, advancing precision design of MXene architectures.

Reaction kinetics model in liquid and solid phases and its parameterization for room temperature sodium–sulfur battery

AIChE Journal, EarlyView.
Abstract A multipore, multiphase, continuum model is assembled for the first time for room temperature sodium–sulfur (RT Na–S) batteries, with Na+ ion transport and redox reactions in the liquid electrolyte phase and semisolid phase of precipitates softened by the electrolyte solvent, as guided by molecular dynamics simulations in this study ...
