Abstract
This investigation demonstrates the electrochemical performance of glass and glass–ceramic NaMn1−x(VO)xPO4 (x = 0.1, 0.3, 05, 0.7 mol%, and labeled as NM1−xVxP) cathode material system via phase details, structural illustration, electronic conductivity, and reversible capacity, etc. Pro‐crystal calculation analysis is used to monitor Na+ ion pathways’ migration for as‐precipitated NaMnPO4, Na2MnP2O7, and NaVO3 phases. The highest conductivity is achieved (≈5.92 × 10−7 S cm−1) for the glass–ceramic sample having x = 0.3 mol% (NM0.7V0.3P) due to the lowest charge transfer resistance (Rct). Electrochemical measurements of the best conducting sample using coin half‐cell exhibit two distinct voltage plateaus at 2 and 2.9 V versus Na/Na+, facilitating the active centers in two directions. The cyclability test of best‐conducting NM0.7V0.3P glass–ceramic network exhibits adequate reversible capacity up to 97% of the specific capacity even up to 50 cycles, which satisfies its superior stability for longer durations.
