Electrochemical processes in batteries occur in conjunction with a spontaneous reduction in Gibbs free energy resulting from differences in lattice cohesive energies and ionization free energies (in water) of reactants and products, as confirmed quantitatively for many combinations of metals.
The analysis provides an explanation of basic electrochemistry that will help students better understand this important topic. The storage of energy in batteries continues to grow in importance, due to an ever increasing demand for power supplying portable electronic devices and for storage of intermittently produced renewable energy.
Scientists who study electrochemistry long enough memorize the order of the reactions in the table of standard reduction potentials (11) and on that basis develop an intuition about the relative tendency of metals or other species to be reduced; however, this approach is only tenuously connected to meaningful principles of chemistry.
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.
The global transition towards renewable energy sources, driven by concerns over climate change and the need for sustainable power generation, has brought electrochemical energy conversion and storage technologies into sharp focus [1, 2].
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.
