Batteries are ubiquitous in daily life and I took them for granted for such a long time that I felt obliged to write an episode about them. Especially since they work thanks to a very basic concept called Redox Reactions. If you would like to share feedback or have a suggestion for a topic, I can now be reached on twitter under @ChemistryinEve1. Alternatively, you can send an email to [email protected].
