The problem is none of these approaches solve the disposal problem or the dirty bomb problem. You can buy 1,000 of these and build a dangerous device that would require serious clean-up and, obviously, can hurt a lot of people.
So, this will never be in a smartphone or laptop, but perhaps power industrial items that can't be practically charged often like remote robots or sensors. Or applications in space to replace aging, expensive, and heavy RTG's.
