So far Tesla has not really done much in terms of battery tech. Pretty much everything they are doing with 18650 cells in their cars and power walls is hardly ground breaking science. They have managed to make things look incredibly beautiful, but 18650 batteries have been around for a long time. If Tesla starts to do more with different chemistries that will be interesting.
