You are right that that's the big issue. But range/cost/life is not the only issue. A second major issue for potential buyers is the worry that it will take four hours to charge the car. Sitting around that long at a fueling station turns some people off. Faster discharge will apparently mean faster charging. Supposedly graphene also has greater power density and a longer life cycle. So, I guess the pursuit of it is to try and answer the problem you identify, and more.
But it is significantly more expensive in the consumer applications that seem to be appearing finally. But that would possibly change for the better over time.
