Fullerene Intercalation of MXene Toward Super‐Long‐Cycle Sodium Ion Storage

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(33)

Published: May 19, 2024

Abstract 2D layered MXene‐based materials are applied as cation‐intercalation electrode for sodium‐ion batteries (SIBs) due to their structures but suffer from spontaneous restacking during Na + insertion and deintercalation processes, resulting in sluggish reaction kinetics poor cycling stability. Herein, fullerene C 60 is intercalated covalently into the interlayer of Ti 3 2 T x MXene nanosheets by using a low‐temperature hydrothermal between water‐soluble derivative hydrophilic nanosheets, enlarged spacing 12.8 14.1 Å consequently retarded self‐restacking. Moreover, strong electron extraction ability facilitates transfer , enabling faster charge transport transportation. The as‐prepared @MXene hybrid novel anode SIBs, exhibiting outstanding electrochemical performance super‐long @MXene‐based SIB delivers specific capacity 226.8 mAh g −1 at 0.1 A after 300 cycles, which surpasses that obtained pristine anode, retains 94.5% 1 10 000 cycles.
