Fortunately, battery companies are going to start soon producing batteries based on dry-electrode lithium-ion technology using graphene sheets and
ultracapacitor technology using carbon nanotubes, which may increase the per charge range of an electric car by three to four times without going to a larger battery pack. Also, we may see a switch from AC charging to DC charging, which means instead of waiting 3 to 7 hours, it could be as short as under ten minutes! :-)
In short, within the next 20-25 years the technology will have matured enough that most personal vehicles will long-range electric drive systems.
I’m an electrical engineer specialized in power systems. I’ve read about the same hopes and dreams on batteries for decades.
They do continue to make improvements, but not the massive jumps the non-technical headline writers want to lead you to believe.
