Battery-Powered Spacecraft Speed

Even the highest quality of batteries are approximately 40 times *less* energy dense than fossil fuels, making the likelihood of them being used for powering spacecraft instead of jet fuel or nuclear power so much less likely. Yet, there seems to be a push to create electric space vehicles just like there is a push for electric automobiles. What is the likelihood of these catching on, or even being improved in any meaningful way? What is in the spaceflight industry’s future?
