How a battery works 08/03/2012


Components



  • Chemical bath (65% distilled water  H2O , 35% sulphuric acid  H2SO4)
  • Cells
  • Plates covered in lead (negative)
  • Plates covered in lead oxide (positive)
  • Negative terminal 
  • Positive terminal
  • Casing
Function
  • The chemical bath acts as an electrolyte (a substance that conducts electricity)
  • The battery has six cells that contain 2 electrodes each. one is positive the other is negative.There are16 individual plates in the cell that form a grid.
  • Each cell produces between 2 and 2.1 volts. They are connected in series which gives the battery an overall percentage of 12 -12.6V
  • The electrons flow from the positive plates (covered in lead oxide) through the chemical bath to the negative plates (covered in lead)
  • The casing holds the chemical bath
  • The positive terminal draws electrons in and the negative pushes the electrons out
