How chemistry is involved in Battery's function

Post  bejoy on Tue Jan 23, 2018 11:54 pm

A battery is an embedded material of one or additional galvanic cells utilized for the production and storing of electrical energy by the means of any chemical. A galvanic cell contains of not less than two half cells which is a reduction cell and also an oxidation cell.

How does Battery work?

When a load is completed the circuit within the two terminals, battery generates the electricity via a sequence of electromagnetic reactions occurring in the anode, cathode and electrolyte. The anode encounters an oxidation reaction in which two or more ions electrically charged atoms. The molecules in the electrolyte unite with the anode, giving rise to composite and letting out one or more electrons. Meanwhile, the cathode departs from a reduction reaction in which the cathode substances, ions and free electrons also unite to form compounds. The reaction in the anode produces electrons, and the reaction in the cathode takes them up. The obtained result or outcome is electricity. The battery will prolong to generate electricity on one or more of electrodes that run out of the compound which is required for the reactions to happen.

Types of Modern Chemical Batteries

1. Zinc-carbon battery: The zinc-carbon chemistry is general and is used in many economical AAA, AA, C and D dry cell batteries. The anode in the battery is zinc, the cathode is manganese dioxide and the electrolyte is ammonium chloride or zinc chloride.
