“…2 (a&b) (Table . 1). Although mixed polyanion glass cathode networks are predicted to have the best precipitation propensity of a few chosen nanocrystalline phases, GC-NaCu 0.7 (VO) 0.3 PO 4 (x = 0.3 mol%) glass-ceramic cathode networks are envisaged to give the highest values of both ΔT and K gl in comparison [16,[30][31][32] . Despite having a lower K gl value than the other samples being studied, the GC-NaCu 0.7 (VO) 0.3 PO 4 (x = 0.3 mol%) glass-ceramic cathode network has emerged as our preferred choice.…”

This investigation presents mixed polyanion G-NaCu1 − x(VO)xPO4 (x = 0.1, 0.3, 0.5,0.7and 0.9 mol%) glass-based cathode material network prepared using the melt-quenching process followed by heat-treating at its Tcfor 5h to form its glass-ceramic(GC- NaCu1 − x(VO)xPO4). The best crystalline NaV2O5 (ICSD 760908) NaCu(PO4)(ICSD 581303), and Na2Cu(P2O7)(ICSD 556822) phases precipitated in the glass network during crystallization will accommodate sudden volume changes, resulting to trigger the fast diffusion of Na+ ions in the glass-ceramic network leading to fast rate capability and voltage for longer durations. The lowest charge transfer resistance Rct = 7.086x103Ω from 1st to 1000 cycles and highest retention of discharge capacity (99.71%) when the current rate is decreased from 10C to 0.1C, determines its long-term cycle life stability and rate capability more than other crystalline compounds.

We synthesized Bulk Metallic Glass (BMG) matrices using the general formula [Ni-(Mo/Cr)-Si]100−x:[Ti/Nb]x (x = 0–15 at.%) via mechanical high energy ball milling technique. Among them, one best sample is targeted in each series, based on their superior structural, thermal, mechanical and corrosion properties which are labeled as - NMST6 ((Ni75Mo15Si10)94Ti6), NMSNb10 ((Ni75Mo15Si10)90Nb10), NCST8 ((Ni75Cr15Si10)92Ti8) and NCSNb6 ([Ni-Cr-Si]94[Nb]6). The results revealed that mixing of optimum quantities of Ti/Nb content in the present BMG network helped to avoid embrittlement, overcome strain cracking problems, prevent pitting, and improved corrosive resistance which is essential to suit aerospace and lightweight vehicle applications. The variation in thermal (ΔT, Trg), mechanical (σy, εp, hardness) and potentiometric parameters (Ec, ic, Ep, ip) of all the targeted samples explained in the light of structural variation and glass modifying features due to the substitution of Ti/Nb in optimum quantities.
