The microscopic chemical environment of Na in Na3V2(PO4)3 was observed and analyzed using solid-state nuclear magnetic resonance. The results demonstrated that Na in the two chemical environments in Na3V2(PO4)3 corresponded to the signal peaks between 80 and 16 ppm in the 23Na NMR spectrum. The peak at around −11 ppm was assigned to impurities, possibly containing sodium carbonate. On basis of the new assignment, the 23Na spectra of Na3V2(PO4)3 under different charging and discharging conditions were investigated and well explained.

重新审视 Na3V2(PO4)3:高分辨率固态 NMR 研究
使用固态核磁共振对Na 3 V 2 (PO 4 ) 3中Na的微观化学环境进行了观察和分析。结果表明,Na 3 V 2 (PO 4 ) 3 中两种化学环境中的Na对应于23 Na NMR光谱中80至16 ppm之间的信号峰。-11 ppm 附近的峰归属于杂质,可能含有碳酸钠。在新分配的基础上,Na 3 V 2 (PO 4 ) 3的23 Na 光谱 在不同的充电和放电条件下进行了研究和很好的解释。
