Lithium ion battery technology is not a good fit with the type of vehicles we currently produce. The energy density is nowhere near fossil fuels and this implies a big battery, which also adds mass. By 2027, Land Rover and other makers of SUV will be nudging 3000kg for some of their models.
IMHO the only viable solution for li-ion is ultralight vehicles. Bicycles and Velomobiles are light enough to get decent range at speed. A bicycle used with integrated high speed rail would solve most of our commuting problems. The fact is, whether you are making tailpipe emissions or not, F=ma. Moving a 3t mass around for one person is always going to use an extravagant amount of energy and that energy has to come from somewhere.
Work from home, eat less meat, make fewer journeys, use a bike more often, make fewer children. Those are some things most of us can do.
Yes the energy density is less, but the efficiency is better. ICE wastes like 2/3 of that extra energy. Still has more, but 1/3 that you might think.
