Existing cathode electrode materials used in commercially available lithium-ion batteries (LIBs) exhibit inadequate electrochemical performance at low temperatures, significantly constraining their utility in regions with cold climates. Promising in this context, the NASICON-structure Na3V2(PO4)3 (NVP) nanomaterial was successfully synthesized using a modified Pechini method and consequently evaluated in LIBs. Benefiting from the reduced particle size and mixed ions resulting from the replacement of Na with Li ions, the cathode exhibits an exceptionally high performance at both room and low temperatures, demonstrating at −20 °C the capacity of 83.05 mAh g−1 at 0.2 C, which is 84.33% of that at the room temperature. With such remarkable efficiency, NVP emerges as a compelling cathode candidate for low-temperature LIBs.
