Along that line, I found this article about John
Goodenough, co-inventor of the lithium-ion battery, to
be encouraging. John just invented another new battery,
which he says will knock the li-ion battery dead. He's 94
years old and his comments about invention and age are
interesting:

Science Friday ran a small segment on new battery tech awhile back:

I don't remember them mentioning John but they covered several things
being researched...

The following was thought to be close to production:

The most promising battery the documentary team came across is being
developed by Tufts University Professor Mike Zimmerman, Pogue says.
Hes confronted the problem of lithium-ions explosive liquids head on
€” by eliminating the liquids.

"He's made a solid sheet of a special plastic, a special polymer, that
lets the ions travel back and forth between the electrodes even better
than a liquid electrolyte does," Pogue says. "And yet, because its a
physical barrier, you cant short out like lithium-ion batteries can.
So these are plastic electrode batteries..."

Interesting stuff

Yeah, I'll say it's interesting. The Braga/Goodenough battery uses a glass electrolyte and sodium, as an alternative to lithium:

Let's hope one or more of them pan out.
