Batteries suck. The overheat, get too cold, wear over time, and sometimes explode. Batteries have been around for hundred of years, yet it feels like they still have a long way to go. Why is it so hard to make a good battery?

We’ll get to that, but first it’s time for some etymology. The word battery in the technological use, stems from the middle english, bateri, which means “forged metal wire.” Ben Franklin then used it for the first time in the modern sense in 1748- which was actually before the battery was invented. Alessandro Volta did that in 1800, when he made the first voltaic cell. It had all the main aspects batteries still have today- an anode, a cathode, and an electrolyte.

Ben Franklin used the word to describe Leyden Jars in the 1740s, which weren’t actually batteries. They were glass bottles that were filled halfway with water. A copper wire was inserted through the top into the wire, and then static electricity was funneled into the wire via a cloth or crank. The jars then held the electrons, and would deliver a charge when touched. This video, "Batteries have been around for 2000 years, but still have a lot of room for improvement.
