NASICON fast-ionic conductors have been largely considered as a viable solution for the development of energy storage units. Due to its three-dimensional framework and high operating voltage, NASICON-type material has been extensively investigated for sodium-ion batteries. Chemical doping is an effect technique to improve the electrochemical performances. The Mn-based NASICON-type Na4VMn(PO4)3 materials are promising cathode materials for sodium-ion batteries (SIBs) due to their environmental friendliness and cost-effectiveness. In this study, the NVMP series materials have been prepared at different temperatures and doping ions including both Li and K ions. The electrochemical performance were measured. These results will be presented.
