Abstract

Due to the construction's low cost, ecological appeal, friendliness, great theoretical density, and reliability, the Mg-S battery is an encouraging substitute for the pillar lithium battery. Nevertheless, self-discharge, the delayed conversion reaction pathway, and the absence of readily compatible electrolytes continue to restrict its beneficial uses. In this work, polymer electrolyte used 0.7 wt% polyvinyl alcohol (PVA), (0.3-x)_wt.%(Mg(CF₃SO₃)₂) and _xwt.%Na₂H₂₀B₄O₁₇ (x = 0,0.01,0.02,0.03,0.04,0.05) (PE_x) have been prepared and characterized for usage in Mg-S batteries. Integrating the PVA__(0.3-x)wt.% (Mg(CF₃SO₃)₂)_ _0.04Na₂H₂₀B₄O₁₇ (X₄) with tetraethylene glycol dimethyl ether (G₄) demonstrates effective Mg plating and stripping behavior, good anodic stability (versus Mg/Mg ²⁺), and a significant ionic conductivity (8.09

\times

10⁻⁷ S cm⁻¹ at 323 K). The Mg-S is assembled using an X₄_G₄ electrolyte and delivers a reversible capacity of 100 mAh g⁻¹ after 30 cycles.

期刊介绍： Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
