what element will fluorine replace in lithium bromide qui

Fluorine is a chemical element with the symbol F and atomic number 9. The dielectric constant (or relative permittivity) of LiF is 9.0. The only problem with this novel technology is that fluoride-based batteries have poor recyclability. Researchers in Japan also are testing fluoride-ion batteries as possible replacements for lithium-ion batteries in vehicles. In these layered electride materials, we predict that adding and removing the fluoride ions would cause significantly smaller structural changes, thus helping achieve a longer cycling life, Hartman said. Mishra, assistant professor of mechanical engineering & materials science, said that the new battery materials are both layered electrides. Electrides are a relatively new class of materials that have been known in principle for about 50 years, but it wasnt until the past 10 to 15 years that their properties were better understood, Mishra said.
