There are many import properties of battery, which I don't see mentioned. They talk only about energy density and safety. - What is the Power Density? If it can only charge and discharge slowly, then your Tesla becomes slow and not fun to drive, and you can't fill it up quickly at a supercharger, or maybe even overnight at home. - What is the longevity of the cell? How fast does it degrade with usage? - What are the temperature effects on the cell? Will the cell require a new thermal management system to get full capacity, power, and longevity? - What is the cost?
