Synthesis of Polypropylene Solid State Electrolytes for Batteries Using a Polymerization Heat Chamber

Polypropylene solid-state electrolytes are a material of solid electrolytes. The solid electrolytes were prepared by mixing a hydroxide solution and polypropylene. However, the electrolyte is very sensitive to the temperature change. Temperature is an essential factor in producing an optimal cheap solid-state electrolyte. This study aimed at determining the temperature effect on the solid state electrolyte polymerization. The different solid-state electrolyte were synthesized by varying the number of molarity of the potassium hydroxide, the weight of the polypropylene and the temperature that was used to heat the polypropylene. The solution molarities that were used are 1, 2, and 3 M and the propylene weight was 5, 10 and 15 g and the six temperature levels were used, i.e. 160, 170, 180, 190, 200, and 210 °C. As a result, the voltage is 1.1 V for 2 M of KOH, and the temperature is 180 for the highest voltage production. As a conclusion, with the increase of the molarity of KOH the voltage also increases. A specific temperature needs to be determined to ensure that the maximum voltage is produced by the battery with the solid-state electrolyte. This temperature and molar configuration is important to search a better solid state electrolyte for the battery.
