Unsure if this would meet your criteria of way better, but in a few years at least 3 companies will be mass producing 3D printed solid state batteries that have about 60% the weight of their current size counterpart, about double the capacity and a much higher C rating. That should double the range of current EV's. The only two things holding me back are the lack of EV truck options and the lack of off-menu options to remove remote telemetry but that isn't strictly an EV issue. I would not mind an EV equiv to a Ford F550 Larime provided it also lacked network connectivity. It also needs to operate in -45F ambient temperature and be more than able to push a lot of snow but people here at HN have told me that cold isn't an issue.
