Scalable synthesis of Na3V2(PO4)3/C with high safety and ultrahigh-rate performance for sodium-ion batteries
文献摘要：
NASICON-type Na3V2(PO4)3 is a promising electrode material for developing advanced sodium-ion bat-teries.Preparing Na3V2(PO4)3 with good performance by a cost-effective and large-scale method is signif-icant for industrial applications.In this work,a porous Na3V2(PO4)3/C cathode material with excellent electrochemical performance is successfully prepared by an agar-gel combined with freeze-drying method.The Na3V2(PO4)3/C cathode displayed specific capacities of 113.4 mAh·g-1,107.0 mAh·g-1 and 87.1 mAh·g-1 at 0.1 C,1 C and 10C,respectively.For the first time,the 500-mAh soft-packed symmetrical sodium-ion batteries based on Na3V2(PO4)3/C electrodes are successfully fabricated.The 500-mAh sym-metrical batteries exhibit outstanding low temperature performance with a capacity retention of 83％at 0℃owing to the rapid sodium ion migration ability and structural stability of Na3V2(PO4)3/C.Moreover,the thermal runaway features are revealed by accelerating rate calorimetry(ARC)test for the first time.Thermal stability and safety of the symmetrical batteries are demonstrated to be better than lithium-ion batteries and some reported sodium-ion batteries.Our work makes it clear that the soft-packed symmet-rical sodium ion batteries based on Na3V2(PO4)3/C have a prospect of practical application in high safety requirement fields.
