A battery converts energy stored in the chemical bonds of a material into electrical energy via a set of oxidation/reduction (commonly abbreviated to redox) reactions. Redox reactions are chemical reactions in which an electron is either required or produced by the chemical reaction.
“A battery is a device that is able to store electrical energy in the form of chemical energy, and convert that energy into electricity,” says Antoine Allanore, a postdoctoral associate at MIT’s Department of Materials Science and Engineering.
To understand the basic principle of battery properly, first, we should have some basic concept of electrolytes and electrons affinity. Actually, when two dissimilar metals are immersed in an electrolyte, there will be a potential difference produced between these metals.
Analyzing the energetics of the overall cell reaction can also provide insights into how commercial batteries work and where their energy is stored. The most widely used household battery is the 1.5 V alkaline battery with zinc and manganese dioxide as the reactants. Six 1.5 V cells are also combined in series to produce a 9 V battery.
An electric battery is an energy storage device comprising one or more electrochemical cells. These cells have external connections used to power electrical devices. When providing power, the battery’s positive terminal serves as the cathode, while the negative terminal functions as the anode.
The prediction of the energy of batteries in terms of cohesive and aqueous ionization energies is in excellent agreement with experiment. Since the electrical energy released is equal to the reduction in Gibbs energy, which is the hallmark of a spontaneous process, the analysis also explains why specific electrochemical processes occur.
