Solid-State Battery Could Extinguish Fire Risks (thestack.com)

An anonymous reader writes: "Researchers have designed a new type of battery that, unlike traditional models containing liquid or gel electrolytes, consists purely of solid chemical compounds and is non-flammable, representing a huge boost for improving battery safety," reports The Stack. "Responding to dangers linked to traditional lithium-ion batteries, the team based at the Swiss Federal Institute of Technology in Zurich, has built a solid alternative which contains only solid-state electrodes and electrolytes." The battery is constructed with a layer of highly conductive lithium garnet, which works as a solid electrolyte between two electrodes. The researchers applied the material of the negative pole in viscous form, which allowed it to seep through the porous electrolyte layer. The team was able to temper the battery at 100C. "With a liquid or gel electrolyte, it would never be possible to heat a battery to such high temperatures," the study claims.

Energy density?

[Anonymous Coward]

Unless I'm missing something they were a little vague as to the energy density of this battery technology. The one detail they did appear to provide is that the batteries only function decently at over 200 degrees Fahrenheit. Unless they're dirt cheap or can make some major leaps in their specs I don't think we'll be seeing this technology in any real use for a while.
