Sodium-ion battery using a NASICON-type Na3V2(PO4)3 cathode: quantification of diffusive and capacitive Na+ charge storage

In this present work, NASICON-type Na 3 V 2 (PO 4 ) 3 cathode was synthesized by sol-gel and solid-state routes for sodium-ion battery. The diffusive and capacitive Na + charge storage modes at peak and non-peak potential regions were quantified.
