Nah, see the battery density graph here. Batteries have made great progress already, and it's accelerating because suddenly there are trillions of dollars on the line for anyone that can make big strides in battery technology.
There is a ~~solid state~~ sodium battery factory being built in Japan, I think, and one in America. (Yes, I mixed up my two battery technologies, a common problem in a stagnant field...) But yes, real life isn't a game, you can't immediately use new tech as soon as it becomes viable, and factories take time to build. That doesn't mean that advances haven't been constantly occurring, just like advances continued to occur with NiMH battery technology a decade after lithium was mainstream. Partly, no doubt, because factories are expensive, they take time to build, and companies like to maximize the profits from their investments.
As I mentioned in my other response, our battery capacity and longevity has increased by a factor of 10 in the last 30 years. Charging capacity has increased significantly, as well. And the only reason we don't have more powerful chargers is because we haven't needed them. It will certainly require a different configuration to charge twice as fast, probably with local power storage to reduce the burden on the electrical grid, but the only technical challenge is the power draw, and there are a number of ways to avoid that.
