I know it's stupid but Doubling the size of a AA battery seems cheaper than improving the efficiency?

  weight weight weight size size size. It's that important. Phone batteries, car batteries, drone batteries. Maybe commercial airline batteries one day.

    And if you don't care about weight and size, there are better and cheaper options than lithium anyway.

      I've been designing and building an ebike, and were at the point where even if I threw out weight and size off the equation there's not really anything better than Li-ion for capacity at significant C-rates versus price.
