In Part 2 of our battery episode we continue our discussion with Bernard Kim. We cover all sorts of topics. Why does capacity and thus range go down over time? Why can you brick a Tesla? What are the limits to the speed you can charge a battery? Does the rumbling from a Tesla cause any issue for the batteries? How can we know a battery will actually last for 10 years or more? How new developments in precise measurement instruments impacts the ability to iterate on new chemistries. As well as what is coming next in lithium ion batteries, how much innovation is chemistry limited, vs. manufacturing capability limited.
