That will imply Tesla will no longer be using the standard 18650 Cell mass produced around the world, and instead uses a new specific component made for Car Battery &#x2F; Tesla Energy, Applying your theory it will be larger, uses less metal around the cell etc. I have no idea in cost associated with battery production, but if it was the same as your Soda example, it will likely means the less metal associated with the Battery Cell are significant cost saving.
