For many years now batteries have been our primary source of energy, acting as the driving force behind our business’, transportation and electronic devises, ensuring our day-to-day lives run smoothly. It is safe to say that they play a fundamental role in powering our 21st century lives, but have you ever stopped to wonder where this energy might come from, or just how batteries work?

Alkaline batteries, in particular, have provided us with energy on the go for over two centuries, with the global demand ever-increasing due to the constant introduction of new and innovative portable electronic devises, the industry is always growing, advancing and developing as our understanding of the underlying electrochemical process grows.

While electrolysis, the passage of a direct electric current through an ion-containing solution (Adams, 2014), supports the running of the battery it is redox reactions that primarily drive the batteries function. Redox Reactions occur in a multitude of real life situations every day, from photosynthesis to powering the battery in your computer. A redox reaction primarily involves the transfer of electrons between two chemical species. The compound that loses an electron is oxidized, while the one that gains an electron is reduced (Campbell, 2011). The oxidation and reduction reaction the occurs in the battery are called “half-equations”, as neither can be carried out alone, thus the sole term redox reaction is used. An oxidation reaction is…
