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

Ultrafast Synthesis of a Non‐Noble FeCoNiCrZn Multi‐Element Alloy Electrocatalyst for Alkaline Oxygen Evolution Reaction

open access: yesCarbon Energy, EarlyView.
A nanoporous carbon‐coated FeCoNiCrZn multi‐element alloy on carbon cloth (FeCoNiCrZn‐C@CC) is fabricated by ultrafast pulsed laser irradiation. It has excellent OER performance, achieving an overpotential of only 233 mV at 10 mA cm−2 and remarkable stability for 94 h at 250 mA cm−2, which is due to multiple factors.
