Harnessing Native Al/Si Impurities in Bamboo Black Liquor for Self‐Templated Closed‐Pore Hard Carbon Anodes

open access: yesCarbon Energy, EarlyView.
A scalable strategy utilizing native impurities in bamboo lignin black liquor is proposed to construct a closed‐pore, rich hard carbon. Controlled impurity removal and high‐temperature reconstruction enable the conversion of open pores into abundant closed pores, thereby promoting sodium cluster storage.

Coupled Photocatalytic Hydrogen Production With Selective Biomass Valorization via Active Sites Construction and Electron Transport Channels Engineering

open access: yesCarbon Energy, EarlyView.
A ternary CdS/1T‐WS2/CNTs heterojunction is in‐situ constructed via hydrothermal method, which is used for photocatalytic biomass reforming (biomass‐derived alcohols, lignin). It exhibits outstanding performance: H2 production rate of 26.17 mmol/g/h for benzyl alcohol (BA), benzaldehyde (BD) generation rate of 8.29 mmol/g/h, 90.06% BD selectivity, 100%

Boosting Sodium Storage Activity and Kinetics of Hard Carbon by Remodeling Oxygen Chemistry

open access: yesCarbon 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 ...

Ternary Crosslinking Builds Nanosheet Hard Carbon and Interfacial Polarization Regulates Na⁺ Kinetics in Hard Carbon Anodes

open access: yesCarbon Energy, EarlyView.
Nanosheet Hard Carbon for Fast Na+ Storage ABSTRACT Hard‐carbon anodes for sodium‐ion batteries are often constrained by low initial Coulombic efficiency, severe interfacial polarization, and sluggish Na⁺ kinetics, especially when porosity engineering amplifies electrolyte consumption.

Synergistically Accelerating Zn2+ Transport and Desolvation Through Cation‐Deficient Ion Channels in High‐Performance Zn Metal Batteries

open access: yesCarbon Energy, EarlyView.
The novel ITO protective layer enables ultra‐stable Zn metal anodes. By synergistically accelerating Zn2+ desolvation and Zn2+ transport via its unique structure, the ITO layer suppresses dendrites and side reactions. This results in exceptional stability for over 6000 h at 2 mA cm–2 and stable operation in Zn ||MnO2 full‐cell configurations.
