New IBM battery technology??

Perhaps you missed the announcement earlier this year that the laboratory of John B. Goodenough (that's really his name, btw), the guy who invented lithium batteries, has developed a solid electrolyte that is expected to make possible completely solid state batteries with 2.5 to 5 times the energy density of current lithium ion batteries, with no fire risk, longer lasting, and makes it possible to use sodium instead of lithium, which, being vastly more abundant and thus much cheaper than lithium, should make those batteries much cheaper to make as well.
