Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

open access: yesCarbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Ultra‐Thick Carbon Microhoneycomb Cathode for High‐Capacity Lithium‐Oxygen Batteries

open access: yesCarbon Energy, EarlyView.
This work demonstrates ultra‐thick biochar‐derived carbon microhoneycomb cathodes for lithium‐oxygen batteries. The penetrated macrochannels serve as highly efficient pathways for Li+ and O2 and provide abundant accommodation space for the discharge product. The optimized cathode achieved a high areal capacity of 38.2 mAh cm–2, providing guidelines for

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

open access: yesCarbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Energy‐Efficient Induction Carbonization: Tailoring Pore Structures in Hard Carbon Anodes Toward Enhanced Electrochemical Performance

open access: yesCarbon Energy, EarlyView.
ABSTRACT Hard carbon (HC) is currently the predominant anode material for sodium‐ion batteries; however, its practical application is still limited by insufficient initial Coulombic efficiency (ICE) and plateau capacity. Meanwhile, conventional HC production relies on energy‐intensive carbonization processes with considerable carbon emissions. Here, an
