  • -PRIMARY BATTERY CONVERTS CHEMICAL ENERGY TO ELECTRICAL ENERGY DIRECTLY
    -USING THE CHEMICAL MATERIALS WITHIN THE CELL TO START THE ACTION.
    -SECONDARY BATTERY MUST FIRST BE CHARGED WITH ELECTRICAL ENERGY BEFORE IT CAN CONVERT CHEMICAL ENERGY TO ELECTRICAL ENERGY
    -SECONDARY BATTERY CALLED A STORAGE BATTERY, SINCE IT STORES THE ENERGY THAT IS SUPPLIED TO IT.
  • -USES AN ELECTROLYTIC PASTE
    -THE ELECTROLYTIC PASTE REACTS WITH THE ELECTRODES
    -TO PRODUCE A NEGATIVE CHARGE ON ONE ELECTRODE
    -AND A POSITIVE CHARGE ON THE OTHER.
    -THE DIFFERENCE OF POTENTIAL BETWEEN THE TWO
    ELECTRODES IS THE OUTPUT VOLTAGE..
  • -ELECTROLYTE -- 64% WATER(H20) (SP.GR.=1.000) +
    36% SULFURIC ACID(H2SO4) (SP.GR.=1.83) = ELECTROLYTE (SP.GR.=1.270)
    -THE ELECTROLYTE IS MEASURED BY ITS SPECIFIC GRAVITY.
    -ELECTRODES MUST BE OF DISSIMILAR METALS.
    -POSITIVE IS A COMPOUND OF LEAD (Pb) AND OXYGEN (O2) FORMING LEAD OXIDE (PbO2)
    -NEGATIVE IS SPONGE LEAD (Pb)
    -OXYGEN IN THE POSITIVE PLATE COMBINES WITH HYDROGEN IN THE EXLECTROLYTE TO FORM WATER (H2O).
    -AT THE SAME TIME, LEAD IN THE POSITIVE PLATE COMBINES WITH THE SULFATE RADICAL (SO4) TO FORM LEAD SULFATE (PbSO4)
    -AT THE NEGATIVE PLATE WHERE LEAD (Pb) COMBINES WITH THE SULFATE RADICAL (SO4) TO FORM LEAD SULFATE (PbSO4)

  • E = VOLTAGE
    I = CURRENT
    R = RESISTANCE
    SERIES CIRCUITS, THE TOTAL VOLTAGE IS EQUAL TO THE SUM OF THE INDIVIDUAL VOLTAGES.
    THE CURRENT IS CONSTANT.
    PARALLEL CIRCUITS, THE VOLTAGE IS CONSTANT.
    THE CURRENT IS EQUAL TO THE SUM OF THE INDIVIDUAL CURRENTS.
  • THE WAY BATTERIES ARE CONNECTED DETERMINES THE VOLTAGE AND CAPACITY OF THE BATTERY.

    • 1. LOCATION
    • 2. PLANT
    • 3. EXIDE INDUSTRY  Exide Industries Ltd, the country's largest lead acid storage battery manufacturer and stored energy solutions provider, today declared its first quarter results for the year 2012-13 (April to June).
    • 4. The Battery  A cell or connected group of cells that converts chemical energy into electrical energy by reversible chemical reactions and that may be recharged by passing a current through it in the direction opposite to that of its discharge -- called also storage cell.
    • 5. Types of Batteries  The primary battery converts chemical energy to electrical energy directly, using the chemical materials within the cell to start the action.It is not rechargable. Example-Dry Cell  The secondary battery must first be charged with electrical energy before it can convert chemical energy to electrical energy.It is rechargable. Example-Lead Acid Battery
    • 6. DRY CELL Uses An electrolytic paste. The electrolytic paste reacts with the electrodes to produce a negative charge on one electrode and a positive charge on the other. The difference of potential between the two electrodes is the output voltage.
    • 7. Lead Acid Battery      A Hard plastic container. Positive and negative internal plates made of lead. Plate separators made of porous synthetic material. Electrolyte, a dilute solution of sulfuric acid and water, better known as battery acid. Lead terminals, the connection point between the battery and whatever it powers.
    • 8. Cells  Positive electrode  Negative electrode  Electrolyte  Separator
    • 9. Ohm’s Law  Series circuits, the total voltage is equal to the sum of the individual voltages. The current is constant.  Parallel circuits, the voltage is constant. The current is equal to the sum of the individual currents.
    • 10. Series Connected Batteries  Positive terminal of one cell is connected to the negative terminal of the next, is called a series connected battery.  The voltage of this type of battery is the sum of a individual cell voltages.
    • 11. Parallel Connected Batteries Connect the negative terminal from one cell to the negative of the next cell Connect the positive terminal to the positive terminal, is parallel connected. Voltage remains constant and the current is cumulative.
    • 12. Discharging  Negative plate reaction: Pb(s) + HSO4(aq) → PbSO4(s) + H+(aq) + 2-e  Positive plate reaction: PbO2(s) + HSO4(aq) + 3H+(aq) + 2-e → PbSO4(s) + 2H2O(l)  The total reaction can be written: Pb(s) + PbO2(s) + 2H2SO4(aq) → 2PbSO4(s) + 2H2O(l)
    • 13. Charging Negative plate reaction:      PbSO4(s) + H+(aq) + 2-e → Pb(s) + HSO4(aq) Positive plate reaction:     PbSO4(s) + 2H2O(l) → PbO2(s) + HSO4(aq) + 3H+(aq) + 2e   The total reaction can be written:  2PbSO4(s) + 2H2O(l) → Pb(s) + PbO2(s) + 2H2SO4(aq)    
    • 14. Charging  Clean Battery Terminals.  Attach clamps to the battery in proper polarity.   Keep open flames and sparks away from battery.  Ventilate the battery well while charging.
