Abstract

INTRODUCTION

The main aim of this study is to make energy storage with the use of Copper-Zinc Enhanced with Hydrogel Electrolyte. This project will be useful in times of unanticipated things such as calamities, disasters, and emergency responses that require a temporary supply of energy. This project also focused on obtaining a voltage output of 3V when the layered copper, zinc, and hydrogel electrolyte are tested.

 

METHODS

The researchers prepared 3 different electrolyte solutions: a. 12.5 mL each of saltwater and sodium hydroxide, 25 mL of citric acid,b. 17 mL of saltwater, sodium hydroxide, and citric acid, c. 20 mL each of saltwater and sodium hydroxide, 10 mL of citric acid; to find out whether if there is a significant difference of the voltage exhibited by the different concentration of the solutions. After the experimentation, the researcher was able to make a hydrogel electrolyte by mixing three tablespoons of sodium polyacrylate, 50 mL of an electrolyte mixture, and three teaspoons of graphite powder. From this setup, the voltage output was produced.

 

RESULTS

The result shows that the three different electrolyte solutions produced different amounts of voltages: the first electrolyte solution gives 0.71V, the second electrolyte solution gives 0.73V, and the third electrolyte solution gives 0.79V. This result made the researcher reject the first null hypothesis and accept the first alternative hypothesis. Thus, there is a significant difference in the voltage exhibited by the three different electrolyte solutions.

 

DISCUSSIONS

Based on the data that collected and analyzed, the research concluded that there was a significant difference in the voltage exhibited by the three different electrolyte solutions. A voltage output of 3V was not produced when the layered copper, zinc, and hydrogel electrolyte was tested. Hydrogel electrolyte was produced by mixing three tablespoons of sodium polyacrylate, 50 mL of an electrolyte mixture, and three teaspoons of graphite powder, and it was able to produce a voltage output.
