Na3V2（PO4）3（NVP） is regarded as alternative cathode material for sodium-ion batteries（SIBs） due to its potential high-rate performance and pronounced long-term cycle stability. However, electronic conductivity and tap density are difficult to be balanced. Herein, we report that high-temperature shock（HTS） can prepare “single crystalline like” NVP which combines high-rate capability with high tap density together into one with the assistance of carbon framework and large particle. Thus, high reversible capacity of 110m Ah/g at 0.1 C with 89.9% capacity retention after 1600 cycles at 1 C and specific capacity of 83.5 m Ah/g at 50 C rate has been exhibited. This study provides a novel strategy to guide the production of high tap density, and rate performance polyanionic cathode materials.
