A BATTERY AND A CELL, ANY DIFFERENCE?

2 min read

A battery or a cell is used in our daily activities. The importance of these materials in living is very much. Most often, we use the them interchangeably whereas, they are not the same although, sometimes, they perform similar functions. They are used in most devices at homes, offices, even in the vehicles.

Both battery and cells are electrochemical devices with three major components. The two electrodes (anode and cathode) and the electrolyte. The electrodes are metals through which electron enters and leaves the electrolyte. Anode is the positive electrode while the negative electrode is cathode. The electrolytes are acids, bases or salts which are in liquid (or aqueous) or molten or in the paste. They have different strength of dissociation or ionization. The more the ions produced, the more the voltage. Dilute solutions are believed to produce more ions than concentrated solution. The is because the ions in the diluted form move more freely than in concentrated form.

Common examples of electrochemical cells are Daniel cell, Le’clanche cell, Lead accumulators, Lithium ion battery etc.

DIFFERENCES BETWEEN CELL AND BATTERY

  • A cell is a single unit device which converts chemical energy into electrical energy. It is just a single unit. It has the symbol

           A battery is a group of cells that convert chemical energy into electrical energy. It has the symbol.

  • A cell is usually light and compact while a batteries are bulky and bigger in size.
  • A cell supplies power for a short period while batteries supply power for a longer period.
  • Due to the small voltage it supplies, a cell is used to perform lighter tasks which use small energy. It is used in devices like wall clock, lamps, mobile phones etc. A battery supplies large energy hence it is used in performing heavy duty tasks. It is used in automobiles, inverters.
  • Economically, cells are cheaper than batteries.

  1. Excellent read, I just passed this onto a colleague who was doing a little research on that. And he just bought me lunch as I found it for him smile Therefore let me rephrase that: Thank you for lunch! “Dreams are real while they last. Can we say more of life” by Henry Havelock Ellis.
