Recharged in 60 seconds

It’s been two years since Toshiba announced a lithium-ion battery capable of being recharged in 60 seconds. What’s with the blackout since then? Did they run into some previously undetected technical problems with it? Or was the whole thing just a slightly mis-timed April fools joke (note the timestamp on the press release)?

(I only just read about the whole concept on some obscure blog, referred to by Shoutwire.)

Or maybe I’m just a little too early in my ponderings: Wikipedia tells me commercial applications are to be expected in 2006 or early 2007 although the 2005 sources anticipated products for 2006 already.
