Batteries are the secret to most of the cool "sci-fi" tech we all want but currently can't have.

  Hmm. I think fusion is more important, but I'll take what I can get.

    We have fusion, 1 AU away. Utility PV gives us an EROEI or around 11. That's good enough, such that a focus on storing the output trumps the development of more abundant local production.

      The sci-fi I'm most interested is a lot more distant than 1 AU.

  Not so much batteries, but "energy storage" in general. Batteries being one very important type of energy storage. If photovoltaics and/or wind become extremely cheap, to the point where the cost is 1 cent/kilowatt-hour, it would even be economical to crack hydrogen from seawater via electrolysis (a process that consumes vast amounts of electricity) and use hydrogen as storage.
