Only problem is who will keep replacing and buying new batteries?...like the old cameras, the money was made in selling film

Just a few points:

(1) That didn't keep Lithium batteries from replacing Ni-Cd or Ni-Mh batteries. For all their problems, Lithium batteries are infinitely superior to their predecessors so they won the day.

(2) Device manufacturers will drive demand. Apple devices have been equipped with non-user replaceable batteries for years and other manufacturers are following suit. A technology that can make the battery live throughout the expected life of the device and make it give a better user experience would make their product more appealing.

(3) Lithium batteries go all explody when damaged. There's an ongoing push to outlaw their shipment by air. Some carriers already refuse to carry them unless they're installed in a device. An alternate technology that was both superior in performance and safer would probably be the tipping point that got the Lithiums banned from air (and maybe other forms of) transportation and you can't sell what you can't ship.
