Honda, NASA and CalTech announced alternative to Li-Ion batteries

Honda Research Institute associated with the California Institute of Technology and NASA’s Jet Propulsion Laboratory has created a battery which provides higher energy density and a better ecological balance than preceding battery technologies.

The new battery chemistry supplies almost 10 times greater energy density and upward to ten times more energy than current battery tech. The breakthrough announced  in Science magazine is that they have succeeded in creating a fluoride ion battery (FIB) working at room temperature.

Unlike lithium-ion batteries, FIBs aren’t that prone to overheating, and procuring the raw materials for FIBs is much more environmentally friendly than pulling cobalt and lithium.

Although FIBs are considered strong candidates for next generation of high density power cells, their particular temperature conditions made them unsuitable for ordinary usage. Currently, ion-conducting solid-state fluoride batteries have to be used at temperatures over 302 °F (150 °C) for the electrolyte to become conductive.

To create the battery which could be used in smartphones or electric cars, the study group succeeded in building of a stable liquid fluoride-based electrolyte with higher working voltage and high ionic conductivity. Combined with a cathode composite with a so-called copper-lantanum-fluorine core-shell nanostructure, the researchers revealed reversible electrochemical cycles working at room temperature.
