Hi, One of the constraints placed on battery design is they should be able to charge as fast as possible. However this constraint is a hang over from the gasoline age. The intent is to allow fast charging at a "gas station". However, in future, most cars will charge using power provided by solar panels on the roof, either at home or at work. This will happen on a daily basis while the vehicle is not in use, so there is no real need for a fast charging capability for the majority of cars, which are primarily used to commute anyway.
The only thing that actually needs to change is the mentality of the car owners, and this will happen as people get used to the concept. Gas stations themselves will become obsolete, and eventually be phased out altogether. If an electric vehicle can drive about 4 hours on a single charge, then that should be sufficient, on long trips, as people stop for meal breaks etc. roughly that often anyway, and the car can be recharged during the meal. This implies that there will be a growing market for recharging bays in the parking lots of highway restaurants, and those that offer this facility, will find that they increase their patronage. Buy electric cars and recharge them from solar panels on your roof.
