Nanomaterials are extensively studied in electrochemical energy storage and conversion systems because of their structural advantages. However, their volumetric energy density still needs improvement due to the high surface area, especially the carbon based nanocomposites. Constructing hierarchical micro-scaled materials from closely stacked subunits is proposed as an effective way to solve the problem. In this work, Li3V2(PO4)3@carbon hierarchical microspheres are prepared by a solvothermal reaction and subsequent annealing. Hierarchical Li3V2(PO4)3 structures with different subunits are obtained with the aid of polyvinyl pyrrolidone (PVP). Moreover, excessive PVP interconnect and form PVP-based hydrogels, which later convert into conductive carbon layer on the surface of Li3V2(PO4)3 microspheres during the annealing process. As a cathode material for lithium ion batteries, the 3D carbon wrapped Li3V2(PO4)3 hierarchical microspheres exhibit high rate capability and excellent cycling stability. The electrode has the capacity retention of 80% after 5000 cycles even at 50C.

Lithium vanadium phosphate (Li 3 V 2 (PO 4 ) 3 ) has been extensively studied because of its application as a cathode material in rechargeable lithium ion batteries due to its attractive electrochemical properties, including high specific energy, high working voltage, good cycle stability, and low price. In this review, the preparation of technology, structure, Li + insertion/extraction mechanism, and electrochemical properties of Li 3 V 2 (PO 4 ) 3 are introduced, and with particular focus on the relationship of these topics each other. The synthetic techniques of Li 3 V 2 (PO 4 ) 3 , such as high-temperature solid-state method, sol-gel method, hydrothermal method, etc. And progress of techniques in modification, such as coating and elemental doping, is reviewed. Finally, the directions for further development and prospective applications for the material are proposed.

“…At present, many synthesis methods have been developed to optimize cathode materials for Li ion batteries, such as carbothermal reduction method [39], hydrothermal method [40], microwaveassisted hydrothermal method [41], solegel method [42], biotemplate-assisted solegel reaction process [43], templating method [44], and two-step ball milling combined with spray drying method [45], etc. Among them, solegel method has abstracted much attention owing to the relative superiorities such as the molecular-level homogeneity of raw materials, low calcination temperature and fine products, etc.…”
