What do you mean wait? How long must we wait? The technology is nearly 20 years old...
"Its use as a battery electrode was first described in published literature by
John Goodenough's research group at the
University of Texas in 1996"
Furthermore, the batteries used by the military, especially in astrospace applications, blow the fuck out of any consumer battery. I do consulting work from time to time for a company which manufactures military grade batteries which go into satellites and other high end military applications.
Like I've said, consumer battery technology is disgustingly behind time. The consumer market is at least 50 years behind the military in terms of technology.
