Results and Recommendations

Documenting Results 

The outcomes of this project must give a recommendation of percentage of alum and magnesium sulpfate that must be mixed with distilled water to get maximum performance of the battery based on these parameters:

  • Amount of alum added in distilled water
  • Amount of magnesium sulfate added in distilled water
  • Time taken to completely charge the battery. The results must be documented in intervals of 10 minutes and percentage of battery charge. 
  • Time taken to discharge the battery. The results must be documented in intervals of 10 minutes and percentage of battery charge.

Notes:

  • When starting the project, start with a fully saturated electrolyte in 1 liter of distilled water (max saturation electrolyte).  
  • Reduce the saturation in subsequent trials by adding different quantities of distilled water to each trial. 

 

Publishing Recommendations

A detailed report of the recommendation must accompany the results. The recommendation must specify the following:

  • Quantity of chemicals per liter of distilled water
  • Fastest and slowest charging time
  • Fastest and lowest discharging time
  • Energy density of the resultant battery
  • Precautions on handling components, battery, chemicals, charging stations and testing and measuring equipment
