This paper reports effect of dispersing active MgO nano-particles in small amount within magnesium-ion conducting polymer electrolyte matrix. The electrolyte films are prepared by solution casting techniques and experimental techniques are employed to carry out structural, electrochemical and mechanical analysis. SEM and AFM micrographs demonstrate a variation in surface morphology and maximum roughness height with the incorporation of MgO nano-particles within the polymer electrolyte matrix. The nano-composite polymer electrolyte film with optimized concentration of 1 wt% MgO nano-particles delivered an ionic conductivity of 1.49 $\times$ 10⁻⁴ S cm⁻¹ at 25 °C, though its crystallinity is higher than the pristine. In depth, ion-conduction has been probed with the help of dielectric and modulus behavior of electrolyte system as a function of MgO nano-particles concentration, frequency and temperature. The mechanical studies reveal a Young’s modulus of 150 N mm⁻², mechanical strength of 2.7 Kgf and stress of 2.6 N mm⁻² at a maximum load of 10 Kgf for the optimized electrolyte film. The reported electrolyte can be utilized in rechargeable Mg batteries due to its high conductivity, flexibility and mechanically stability.

本文报道了将少量活性MgO纳米颗粒分散在镁离子导电聚合物电解质基质中的效果。通过溶液流延技术制备电解质膜，并采用实验技术进行结构，电化学和机械分析。SEM和AFM显微照片表明，在聚合物电解质基质中掺入MgO纳米颗粒后，表面形态和最大粗糙度高度发生了变化。最优化浓度为1 wt％的MgO纳米颗粒的纳米复合聚合物电解质膜的离子电导率为1.49 $\times$尽管其结晶度高于原始，但在25°C时为 10 ^-4 S cm ^-1。深入地，已经借助于电解质系统的介电常数和模量行为来探究离子传导，该行为是MgO纳米粒子浓度，频率和温度的函数。力学研究表明，对于优化的电解质膜，在最大载荷为10 Kgf时，杨氏模量为150 N mm ^-2，机械强度为2.7 Kgf，应力为2.6 N mm ^-2。所报道的电解质具有高导电性，柔韧性和机械稳定性，因此可用于可充电镁电池。
