Sodium-ion batteries (SIBs) have emerged as a promising candidate for large-scale stationary energy storage in light of possible concerns over cost and abundance. Advanced sodium host materials are required for developing SIBs with high energy density, long cycling stability and high safety. Layered metal dichalcogenides (MX2, M = Mo, W; X= S, Se) have become a hot spot for anode materials in SIBs due to their logical component and high theoretical capacity. However, the sluggish Na+ diffusion kinetics lead to poor electrochemical behaviours. In this talk, I will present an emphasis that is placed on enhancing the electrochemical Na+ storage performance through spatial nanoarchitectonics design, including vertical alignment, interlayer engineering and orientation stacking. It is hoped that light is shed on the further development of SIBs in view of their high capacity, long-term stability and volumetric energy density. |
