different types of batteries



Batteries produce electricity by way of spontaneous chemical reactions. basically, a battery is filled with chemicals that be capable of produce electrons. Electrons are tiny microscopic particles found within atoms and molecules. Atoms and molecules in turn are the tiny building blocks that make up the whole lot including the air, the earth, even ourselves. Chemical reactions that produce electrons are called electro-chemical reactions.


Batteries work by means of oxidation/reduction ( redox) reactions, involving transfer of electrons. Oxidation/ discount reactions are electron switch reactions. For a battery to work, both an oxidation and a reduction must occur. One generates electrons at one electrode, and the opposite uses them up at the other electrode. If the electrodes are related outdoor the cell by using a conductor, electrons go with the flow and the whole reaction is completed.




era of present


 because of producing electrons, electro-chemical reactions produce a kind of vitality or 'energy' known as chemical vitality. Electrons shifting along a conductor are what we call electricity or electrical present.  This power can be saved within a battery except it's converted into electrical vitality.  The electrode where oxidation ( lack of electrons) takes situation is called anode. On a battery it's marked as the “-“ aspect. discount is when a chemical reactant accepts electrons. It finally ends up with extra electrons that it started with. On a battery it is marked because the “+“ side. The anode releases electrons, and leaves at the back of positively charged ions. The cathode accepts electrons.  This glide of electrons result in  present.
