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) (PEx) 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 × 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 |
