Summary: Sodium-ion batteries (SIBs) are considered as a promising alternative to lithium-ion batteries (LIBs) due to their abundant resources. Na3V2(PO4)3 (NVP) is a promising cathode material for SIBs, thanks to its unique structure, good stability, and fast sodium diffusion kinetics. However, its weak intrinsic conductivity hinders its further market application. Various strategies, such as foreign ion doping and carbon coating, have been proposed to solve this issue.

Summary: In this study, the electrochemical properties and reaction mechanism of Li3-2xCaxV2(PO4)(3)/C as negative electrode materials for sodium-ion/potassium-ion batteries were investigated. It was found that the Ca content influenced the diffusion-controlled and pseudocapacitive-type processes in the batteries. Li3V2(PO4)(3)/C showed the highest reversible capacity, while Ca1.5V2(PO4)(3)/C exhibited the best rate performance. It was also discovered that the specific capacity of the material did not increase with Ca-content, but the stability and performance at high C-rate improved by replacing Li+ with Ca2+.

Summary: In this study, a chemical strategy was adopted to improve the rate performance of the sodium superionic conductor (NASICON)-Na3V2(PO4)(3) (NVP) cathode for sodium-ion batteries. Partial replacement of V3+ by low-valence Mn2+ and high-valence Mo6+ substitution resulted in enhanced electronic conductivity and improved electrochemical performance. The Mn-Mo-doped NVP cathode exhibited smoother charge-discharge profiles, better rate performance, higher energy density and superior Na-ion kinetics compared to the unsubstituted NVP@C cathode.
