Deep Layer Pillaring Reinforced Electronic States and Structural Defects Toward High‐Performance Sodium Ion Battery (Adv. Energy Mater. 8/2025)

Sodium Ion Batteries

In article number 2404685, Xin Guo, Jun Liu, and co-workers demonstrate a new approach to modulating the electronic structure of vanadium-based oxide by incorporating Na⁺ cations into deep V─O layers, ensuring reconstructed low-energy barrier channels and maximized exposure of active sites. This work showcases high-performance sodium-ion battery anodes with fast and reversible Na⁺ pseudocapacitive multi-electron reactions.
