Emerging sodium-ion batteries (SIBs) devices hold the promise to leapfrog over existing lithium-ion batteries technologies with respect to desirable power/energy densities and the abundant sodium sources on the earth. To this end, the discoveries on novel cathode materials with outstanding rate capabilities are being given high priority in the quest to achieve high power density SIBs devices, and the multi-dimensional Na migration pathways with low diffusion energy barriers are crucial. In light of this, the recent development of Prussian blue analogs and sodium superionic conductor (NASICON)-type materials with 3D Na diffusion pathways for building high power density NIBs are provided in this perspective. Ultimately, the future research directions to realize them for real applications are also discussed.
新兴的钠离子电池(SIBs)器件有望在理想的功率/能量密度以及地球上丰富的钠资源方面超越现有的锂离子电池技术。为此,在寻求实现高功率密度SIBs器件的过程中,具有出色倍率性能的新型阴极材料的发现被给予了高度重视,而具有低扩散能垒的多维钠迁移途径至关重要。有鉴于此,本文综述了普鲁士蓝类似物和具有三维钠扩散途径的钠超离子导体(NASICON)型材料在构建高功率密度 NIBs 方面的最新进展。最后,还讨论了将它们实现实际应用的未来研究方向。
