Answer:
multiple voltaic cells that have spontaneous half reactions
Explanation:
A battery is an electrochemical device that stores energy. This is connected to an electrical circuit, and chemical energy is transformed into electrical energy. All are similar in construction, each of these cells is composed of a positive and a negative electrode in addition to a separator. When the battery is discharged, an electrochemical change occurs between the different materials in the two electrodes. The electrons are transported between the positive and negative electrodes through an external circuit (light bulbs, starter motors, etc.)
