The NASICON Al-doped LiGe2(PO4)3 (Li1.5Al0.5Ge1.5(PO4)3: LAGP) is one of the promising solid electrolytes that intensively optimized in solid-state Li-ion batteries. However, its underlying fast diffusion kinetic has not been fully understood yet. In this context, density functional theory (DFT) calculations were performed to comprehend migration behaviors LAGP, especially under emergence metas...

The luminescence properties of NASICON-type Na3.6M1.8(PO4)3 (M = Y, Lu) and Na3Sc2(PO4)3 phosphates, undoped rare earth-doped (RE Tb3+, Dy3+, Eu3+, Ce3+), were studied using synchrotron radiation in a wide energy region 4.5–45 eV. Intrinsic emission originating from self-trapped excitons with electron component localized at the 3d Sc states was detected both doped while only defect-related regi...

In this work, we investigate the crystal chemistry of Fe/V-mixed NASICON [sodium (Na) Super Ionic CONductor] compositions Na3FeV(PO4)3 and Na4FeV(PO4)3 that are structurally related to Na3V2(PO4)3, a positive electrode for Na-ion batteries. To synthesize Na4FeV(PO4)3, various synthesis routes (solid-state, sol–gel-assisted, electrochemical syntheses) were investigated. Direct syntheses resulted...

Abstract The growing concern about scarcity and large-scale applications of lithium resources has attracted efforts to realize cost-effective phosphate-based cathode materials for next-generation Na-ion batteries (NIBs). In previous work, a series (such as Na 4 Fe 3 (PO ) 2 (P O 7 ), VCr(PO , VMn(PO MnTi(PO MnZr(PO etc) with ∼120 mAh g −1 specific capacity high operating potential been proposed...

Six NASICON type samples with Na4-xVFexMn1-x(PO4)3 (0 ≤ x 1) stoichiometry are examined as positive electrodes for sodium-ion batteries. The structural, morphological, and chemical state of elements in raw is unveiled by XRD diffraction, electron microscopy, Raman XPS spectroscopies. effect the dual Fe/Mn substitution electrochemical tests using both voltammetric galvanostatic methods. results ...
