Waste Sawdust‐Derived Hard Carbon Anodes With Engineered Interlayer Spacing for Sodium‐Ion Batteries Exhibiting High Initial Coulombic Efficiency

ABSTRACT In sodium‐ion battery systems, hard carbon (HC) is regarded as one of the most promising anode materials. Nevertheless, its limited initial Coulombic efficiency (ICE) or high cost has impeded its widespread application. This study introduces a strategy for synthesizing u...

Strain‐Buffering Layered/Rocksalt Heterostructure Constructed via Oxygen Redox Activation for Durable O3‐Type Layered Transition Metal Oxides

ABSTRACT Harnessing anionic oxygen redox is pivotal for boosting the capacity of O3‐type layered transition metal oxides for sodium ion batteries (SIBs), yet it often triggers severe lattice distortion and irreversible oxygen release. Herein, we propose an in situ electrochemical...
