"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.
