New co-authored paper demonstrates potential ten-fold energy density increase over existing lithium-ion battery technologies.

Researchers Develop new Battery chemistry with 10X More Energy Density over Lithium

Scientists from Honda Research Institute have collaborated with researchers at California Institute of Technology (Caltech) and NASA’s Jet Propulsion Laboratory to develop a new battery chemistry that enables the use of materials with higher energy density and a more favorable environmental footprint than current battery technologies. The collective team of scientists co-authored a new paper on the topic that was published in Science and is available at http://science.sciencemag.org/cgi/doi/10.1126/science.aat7070.

The joint study reports that the research team has opened new doors in the development of high energy-density batteries capable of meeting rapidly growing energy storage needs by overcoming the current temperature limitations of fluoride-based battery (FIB) technology and by demonstrating the room-temperature operation of fluoride-ion based energy cells.

Fluoride-ion batteries offer a promising new battery chemistry with up to ten times more energy density than currently available Lithium batteries,

said Dr. Christopher Brooks, Chief Scientist, Honda Research Institute, and a co-author of the paper.

Unlike Li-ion batteries, FIBs do not pose a safety risk due to overheating, and obtaining the source materials for FIBs creates considerably less environmental impact than the extraction process for lithium and cobalt.

FIBs provide an attractive alternative to other types of potential high-energy battery electrochemistries, such as those based on lithium- or metal hydride chemistries, which are generally limited by the inherent properties of their electrodes. Due to the low atomic weight of fluorine, rechargeable batteries based on the element could offer very high energy densities–up to 10 times greater than the theoretical values for lithium-ion technologies. However, while FIBs are considered a strong contender for the “next-generation” of high-density energy storage devices, they are limited by their required temperature requirements.
