Phase Engineering of MXene Derivatives Via Molecular Design for High-Rate Sodium-Ion Batteries

Energy & Environmental Materials 2024年第5期7卷 126-134页

Since 2019, research into MXene derivatives has seen a dramatic rise; further progress requires a rational design for specific functionality. Herein, through a molecular design by selecting suitable functional groups in the MXene coating, we have implemented the dual N doping of the derivatives,nitrogen-doped TiO2@nitrogen-doped carbon nanosheets （N-TiO2@NC）, to strike a balance between the active anatase TiO2at low temperatures, and carbon activation at high temperatures. The NH3reduction environment generated at 400℃as evidenced by the in situ pyrolysis SVUV-PIMS process is crucial for concurrent phase engineering. With both electrical conductivity and surface Na+availability, the N-TiO2@NC achieves higher interface capacitive-like sodium storage with long-term stability. More than100 mAh g-1is achieved at 2 A g-1after 5000 cycles. The proposed design may be extended to other MXenes and solidify the growing family of MXene derivatives for energy storage.

聚氧乙烯基聚合物固态电池具有高安全性和高能量密度的特点,极有可能成为下一代储能器件.然而,聚氧乙烯基电解质本身的电化学窗口窄,极大的限制了其能量密度的进一步提升.目前适配聚氧乙烯基电解质且长循环稳定的正负极材料较少,这严重阻碍了聚氧乙烯基聚合物固态电池的广泛应用.其主要问题在于电极材料与聚氧乙烯聚合物电解质之间的负极界面和正极界面都容易发生副反应,大大地缩短了电池的循环寿命.为了抑制这些副反应,人们采取了相应的策略,取得了一定的成效.为充分理解固态电池界面处的变化,可采用各类先进表征手段对其进行研究,这将为下一步提高固态电池循环稳定性提供更科学的依据.
