The Honda Research Institute has announced a new breakthrough battery chemistry developed in collaboration with researchers from Caltech and NASA JPL. The technology described in detail in a recently published study has a better environmental footprint and allows the use of higher energy density materials compared to existing battery technologies.
Honda says the new technology overcomes the temperature limitation of fluoride-based battery technology. The team successfully demonstrated the operation of room temperature fluoride ion-based energy cells, opening the door to high-energy-density batteries that better meet the high-capacity demands of modern technology.
Even better, according to the researchers, fluoride ion batteries, unlike widespread lithium-ion batteries, which are known as volatile, safer, without the risk of overheating. This battery technology is also better for the environment because of the lower environmental impact of the starting materials.
According to the study, batteries made with chemicals can be up to ten times as high as lithium-ion batteries. Despite the drawbacks, this battery type has not replaced lithium-ion due to its temperature limitations – previously, temperatures above 302 ° C were required to function properly.
Researchers with Honda, NASA and Caltech have overcome this limitation and developed a fluoride ion cell that can operate at room temperature. The team achieved this with a fluoride-conducting liquid electrolyte that has high ionic conductivity and high operating voltage. One day, this technology could be behind batteries that drive everything from consumer appliances to electric vehicles.
