The presentation discusses electric vehicle batteries, comparing the curb weights of a Tesla Model S and Mercedes Benz C class, with the Model S weighing more due to its 85kWh battery pack weighing 540kg. It explores the anatomy and shape of electric vehicle battery packs as well as battery chemistry and alternatives, touching on limitations of lithium supply and raw materials while also considering viable alternative battery technologies like aluminum air, hydrogen fuel, and sodium-ion batteries.
