EDITOR'S NOTE: If you don't have the time to set aside two hours to watch the full video above, you're in luck. Sean Mitchell has broken the video down with timestamps, along with producing and providing three short videos (embedded below) with the most pertinent information.

If you're a hardcore Tesla and EV fan and follower, you may have a pretty good grasp of how batteries work, though that doesn't seem to be the case when it comes to the masses.

Interestingly, while batteries are present in many capacities in our daily lives, many of us just use them without really understanding them. This is because you don't really need to "get it" to use it. However, as an EV owner, it becomes more important to be educated on the subject.

Our good friend Sean Mitchell recently sat down with Ph.D. student and scholar Ravindra Kempaiah to talk batteries and get some answers. If you have the time, the entire interview is well worth watching. If not, start with the timestamps and shorter videos below.
