Moving Beyond 99.9% Coulombic Efficiency for Anode‐Free Sodium Metal Battery
Carbon Energy, EarlyView.Iron‐anchored carbon nanotubes (CNT‐Fe) are developed as a 3D sodiophilic host for anode‐free sodium metal batteries. The Fe nanoparticles significantly enhance sodium adsorption and ensure uniform deposition, enabling an exceptional 99.9% Coulombic efficiency over 1100 cycles and long‐term stability in high‐loading full cells.

Boosting Sodium Storage Activity and Kinetics of Hard Carbon by Remodeling Oxygen Chemistry
Carbon Energy, EarlyView.A surface oxygen remodeling strategy is proposed to finely furnish the pseudographitic structure of hard carbon with rich closed pores and expanded interlayer spacings. Accordingly, the sodiation reactivity and kinetics are greatly reinforced to afford an elevated capacity of 360 mAh g−1 and outstanding rate capability of 225 mAh g−1 at 2 A g−1 ...
