Batteries How Batteries Work
Three Main Components of Batteries • Negative terminal (anode): an electrode made of a metal such as zinc that accumulates negative charge ( gains electrons) • Positive terminal (cathode): an electrode made of metal such as copper that accumulates positive charge (loses electrons) • Electrolyte: a liquid solution or paste whose molecules spontaneously seperate into positively or negatively charged atoms or groups of atoms, called ions.
Keys to assembly of an electrolytic cell battery • Two metal strips (electrodes) put into a container • Container filled with an electrolyte (liquid solution that separates positive and negative ions) • The electrodes (metal strips) cannot touch each other.
How does the battery work? • Oxidation-reduction reaction takes place • One electrode accumulates electrons (negative) and the other electrode loses electrons (positive) • The process of separating and accumulating electrons produces the electricity of the battery
