The life and times of battery cells – a machine learning perspective
"There is no question that the electric vehicle has a great future". Surprisingly, it is not Elon Musk who is credited with these words, but W.C. Anderson, president of an electric car company, a little over a hundred years ago. Unfortunately, they were uttered a bit too early, in 1912 – at the same time as Ford was breaking sales records with its Model T, mobilizing the masses at an unbeatable price of 650 USD (roughly 17000 USD today). The future of electric vehicles looked bleak as the world embraced fossil fuels. And now ours does as well, for very similar reasons. The incredible progress in mobility needs to be put on a sustainable foundation for us not to go the way of Mr. Anderson's products. Of course, it would help not to repeat the mistakes of the past – after all, it was the energy density and abundance that made oil the dominant energy source. Which brings us to batteries.
