图1 (a) NASICON结构：蓝色八面体为[Ti/Al]O6，紫色四面体为PO4，绿球为M1位点，黄球为M2位点，M1和M2位点之间的连线为锂离子传输通道[58]；(b) NASICON结构中M1、M2和M3位点的分布[61]

Fig.1 (a) representation of a typical NASICON structure: Blue octahedra are MO6 units, purple tetrahedra are PO4 units, green spheres are M1 sites, and yellow spheres are M2 sites. Pathways for Li+ motion are drawn between M1 and M2 sites[58]; (b) representation of distribution of M1, M2 and M3 sites in NASICON structure[61]
