To further increase the energy and power densities of lithium‐ion batteries (LIBs), monoclinic Li 3 V 2 (PO 4 ) 3 attracts much attention. However, the intrinsic low electrical conductivity (2.4 × 10 −7 S cm −1 ) and sluggish kinetics become major drawbacks that keep Li 3 V 2 (PO 4 ) 3 away from meeting its full potential in high rate performance. Recently, significant breakthroughs in electrochemical performance (e.g., rate capability and cycling stability) have been achieved by utilizing advanced nanotechnologies. The nanostructured Li 3 V 2 (PO 4 ) 3 hybrid cathodes not only improve the electrical conductivity, but also provide high electrode/electrolyte contact interfaces, favorable electron and Li + transport properties, and good accommodation of strain upon Li + insertion/extraction. In this Review, light is shed on recent developments in the application of 0D (nanoparticles), 1D (nanowires and nanobelts), 2D (nanoplates and nanosheets), and 3D (nanospheres) Li 3 V 2 (PO 4 ) 3 for high‐performance LIBs, especially highlighting their synthetic strategies and promising electrochemical properties. Finally, the future prospects of nanostructured Li 3 V 2 (PO 4 ) 3 cathodes are discussed.
