We've now squeezed lithium technology nearly as far as it can go; we may well get vastly better batteries in the future, but if so, it will be (I predict) because we've found a new kind of battery - a revolutionary not evolutionary change.If you had told me energy density of batteries would be up by a factor of seven in less than 20 years I wouldn't have believed you. It hadn't gone up by more than 50% since WWII.
