Fig. 2. Stages of solid electrolyte preparation 
Preparation of electrodes of polymer-based Mg-ion batteries. The composition of the 
electrodes consists of the following materials: magnesium permanganate (MgMnO4), carbon, 
polyvinylidene fluoride (PVDF), N-methylpyrrolidone (NMP). We first extract 0.8 mg of magnesium 
permanganate (MgMnO4), 0.1 mg of carbon (C), 0.1 mg of polyvinylidene fluoride (PVDF), heat the 
MgMnO4 and carbon mixture under vacuum at 80 °C for 5 min, then add PVDF and mix. Once the 
mixture is homogeneous, add 3-4 drops of NMP solvent to it and stir the mixture at room temperature

for one day. Assemble the battery in the following sequence in the sandwich method from the 
prepared samples MgMnO4 / SPE / Mg metal Figure 1-b. 
Conclusion. Polymer-based Mg-ion batteries, which are safer, lighter and more compact than 
traditional Mg-ion batteries, are characterized by high energy and power density, low cost, simplicity 
of manufacturing technology and long-term non-discharge. We recommend the production of these 
batteries in our country.
