Project Development and Results

Documenting Results 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.

 

Sample report report 

Electrolyte 1 [150 grams MGSO4 + 500 grams Alum + 1 liter of distilled water] - CHARGING/DISCHARGING

Percentage Time Time Percentage
10% 00:10 hrs 1:00 hr 18%
20% 01:15 hrs 2:00 hr 28%
30% ---- 02: 22 hrs 3:00 hr ---- 34%
----- 100% 11:45 hrs --- 12:00 hrs 100%

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
