Solid-state Batteries & Optical Lattice Clocks
Batteries and clocks are things we all use every day. But this episode may cause you to think about them in new ways. We'll trace the development of a solid battery electrolyte for lithium ions to pass through. It allows a threefold performance improvement over current lithium ion batteries. And we'll see a demonstration confirming Einstein's idea that gravity alters the speed of time itself! It's done with optical lattice atomic clocks, and their secret ingredient: strontium.
