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

Carbon 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

Modulating Electronic Structure of Atomic Iron Catalyst by Metallic Cobalt Cooperation for Boosting Oxygen Reduction/Evolution Reactions in Rechargeable and Flexible Zinc‐Air Battery

Carbon Energy, EarlyView.
Porous Co,Fe@NCNF‐900 catalyst has been innovatively synthesized as enhanced bifunctional catalysts by modulating the electronic structure of the atomic Fe catalyst through metallic Co cooperation. DFT analysis indicates that metallic Co as an electron donor can induce electron redistribution of the atomic Fe catalyst, thereby reducing the rate ...

Synergetic Heterophase and Selective Defect Engineering of Nano Multicomponent Alloys for Rechargeable Zn–Air Batteries

Carbon Energy, EarlyView.
An fcc/bcc with defects (bcc‐d) MCA is designed by utilizing the interplay between heterophase and selective defect engineering and exhibits excellent electrocatalytic activity suitable for high‐performance zinc–air batteries. The synergistic catalysis of the fcc/bcc‐d breaks the universal linear‐scaling relationships of adsorbed multi‐intermediates ...

Efficient and Durable Sulfion Oxidation Coupled With Hydrogen Production via Cu@Cu2S Heterostructured Nanowires

Carbon Energy, EarlyView.
We present a facile and liquid‐phase approach to synthesize Cu@Cu2S core‐shell heterostructure nanowires derived from copper nanowires at room temperature for robust sulfide oxidation reaction (SOR)‐assisted H2 generation. The Cu@Cu2S core‐shell heterostructure nanowires exhibit superior SOR activity with an ultralow potential of 0.3 V (vs.
