Additional Lecture 2. The Chemistry of Batteries (Intro to Solid-State Chemistry 2019)
[SQUEAKING] [RUSTLING] [CLICKING] JEFFREY C. GROSSMAN: I want to start with this sort of big picture, all right. So we're going to kind of introduce energy storage, and then we'll talk about sort of why electrical storage is kind of a thing and important, and then we'll kind of go into batteries and then talk about the chemistry of batteries and throw in a couple of, why this matters. So if you think about this on a planetary scale, actually, the planet is kind of a storage device. It's an energy storage device for that thing over there, right, and so like if you think about all the energy flows that go on on planet Earth, well, then you've got-- there's a picture I like. It kind of shows you the different energy flows, right. You've got the sun, so you've got like solar radiation. You've got tides, there's the moon, you've got wind. You've got all these kinds of energy happening on the planet, all the way down to life happe...
