Na3V2(PO4)3/C Composite Prepared by Sol-Gel Method as Cathode for Sodium Ion Batteries
Abstract
Na 3 V 2 (PO 4 ) 3 (NVP) composites were prepared by a facile sol-gel method. The optimal synthetic conditions were systematically investigated by orthogonal test method and single factor of calcination temperature, which had maximum effect on the electrochemical properties of the sample. The optimal Na 3 V 2 (PO 4 ) 3 /C (denoted as Opt-NVP/C) has been prepared under the condition of the calcination temperature at 800°C, the molar ratio of NVP to C as 1:1, sol-gel reaction temperature at 80°C and the calcination time of 16 h. The capacity retention decreased by only 2% from the initial value of 106.7 mAh g −1 to 104.5 mAh g −1 after 100 cycles at 0.2C. Enhanced electrochemical performance can be attributed to reduced polarization and stable operating voltage window. The high purity and crystallinity at the proper calcination temperature and porous particles morphologies are related to lower polarization and higher Na + diffusion coefficient, respectively.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
