If you’ve ever used a flashlight, or changed the channel with a remote control, if you’ve ever recharged your electric car, or if you’re reading this on a smart device, then you know how useful batteries can be. But how do batteries work?

Of course, today you might know Volta’s name from the words volt and voltage. Galvani is also honored for his contributions.
