Maybe "eventually", but certainly not in 2 decades, or in our lifetimes, I suspect.
Yes, we need battery tech that is 100x better. Just like we need fully functional robots to do all of our work, infinitely clean air and water etc. I don't think battery tech is in any way "behind" - that assumes it "should" be somewhere way far ahead. Our knowledge of chemistry, physics, and the realities of both are what they are. I don't think anyone is slacking off looking for better batteries.
