Unveiling Dynamic Structural Evolution Mechanism of Titanium Oxide Anode for High-Performance Sodium-Ion Capacitors

Abstract Anatase TiO2 derived rock-salt NaTiO2 has emerged as a superior anode material for efficient sodium ion storage, but the dynamic structural evolution mechanism has yet been fully revealed. Herein, based on comprehensive electrochemical analyses and in situ structural cha...

Catholyte‐Free Composite Cathodes Break the Energy Density Barrier of All‐Solid‐State Lithium Batteries

ABSTRACT The gravimetric and volumetric energy densities of 500 Wh kg –1 and 1000 Wh L –1 are considered as the “holy grail” target values for the development of all‐solid‐state lithium pouch batteries. However, the substantial amount of non‐energy‐providing deformable catholytes...
