Atomic-Scale Intergrowth Regulation Enables Long-Cycling Zero-Strain Sodium Layered Oxide Cathodes

Abstract P2-type layered oxide cathodes feature high median voltage and outstanding cycling stability, but their specific capacity of merely 80 mAh g–1 severely limits practical utility. Conventional P2/O3 biphasic strategies to boost capacity typically sacrifice structural stabi...

Geometry‐Guided Screening of Metal/Oxide Heterointerfaces Enables Superior Sodium Metal Batteries at −40 °C

ABSTRACT Despite their high theoretical energy density, sodium metal batteries (SMBs) remain limited by unstable interfacial chemistry and sluggish Na + transport kinetics, particularly under ultralow‐temperature conditions. Herein, guided by a geometry‐driven design principle li...

A Universal Precipitation‐Transformation Strategy Toward Low‐Defect Prussian Blue Analogs for High‐Performance Sodium‐Ion Batteries

ABSTRACT Prussian blue analogs (PBAs) are considered promising cathode materials for sodium‐ion batteries (SIBs) due to their low cost and open framework structure. However, their practical application is hindered by intrinsic [Fe(CN) 6 ] 4− vacancies and coordinated water, which...
