why does chemical reaction take place in battery and how??? Don't copy directly from goggle
Answers
____________
In a battery a reaction takes place which convert the stored chemical energy in the battery converts to electrical energy.
______
a battery is consist of Cells and each cell have a positive and a negative terminal .
The electron particles get transferred from the positive end (anode)to negative end(cathode ) and and in this a kinetic energy is generated which is converted into electrical impulse.
____
I hope it will help you :-D
Most batteries contain three basic parts: electrodes, an electrolyte and a separator, according to Ann Marie Sastry, co-founder and CEO of Sakti3, a Michigan-based battery technology startup.
There are two electrodes in every battery. Both are made of conductive materials, but they serve different roles. One electrode, known as the cathode, connects to the positive end of the battery and is where the electrical current leaves (or electrons enter) the battery during discharge, which is when the battery is being used to power something. The other electrode, known as the anode, connects to the negative end of the battery and is where the electrical current enters (or electrons leave) the battery during discharge.
Between these electrodes, as well as inside them, is the electrolyte. This is a liquid or gel-like substance that contains electrically charged particles, or ions. The ions combine with the materials that make up the electrodes, producing chemical reactions that allow a battery to generate an electric current.
