Development of a Prototype Power Bank with the Use of Saline Solution as an Alternative Electrolyte

Abstract

INTRODUCTION

Nowadays, the use of power banks are prevalent for its ease of use and easy access. This experimental research aimed to make a power bank with the use of a saline solution as an alternative electrolyte that can be used in emergency situations. Specifically, the research studied the significant difference between the charging ratesof the produced prototype saline powered power bank depending on the saline solution concentration.

METHODS

Using a quantitative method, and experimental research design, the produced prototype power bank undergoes test analysis depending on the concentration. 5%, 11% and 20% saline solution were used to determine its physical characteristics in terms of lifespan and capacity, testing the amount of electricity (v). After assessing, the treatments were compared, if there was a difference between the charging rates of the power banks depending on the saline solution concentration.

RESULTS

In assessing the most acceptable saline solution as an alternative electrolyte to use as a power bank, T1 -with 5% saline solution that has an output voltage of 3.54V and charging rate 25% accumulated percentage per hour is the least performing treatment out of all. T2 -with 11% saline solution that has an output voltage of 5.08V and a charging rate of 30% accumulated percentage per hour is the most suitable saline solution while T3 -with 20% saline solution that has an output voltage of 7.46V and a charging of 35% accumulated percentage per hour which is considered as less performing saline solution for having the most output voltage wherein the most acceptable output voltage is 5V in charging smartphones. Testing for the difference of the suitability of the treatments as an alternative electrolyte in terms of output voltage and charging rate using the one-way ANOVA test, P-value of <0.00001 was obtained which means there is a significant difference between the different saline solution.

DISCUSSIONS

Hence, this study concluded that the most suitable saline solution as an alternative electrolyte to use as a power bank has an 11% saline solution and a 5.08V compared to the other treatments. This study proved that saline solution is suitable as an alternative electrolyte to use in a power bank.
