Iron fluoride cathode materials have emerged as a promising class for next-generation rechargeable batteries, offering high theoretical energy densities and the potential for both lithium-ion and ...

The fluoride ions used in the new study bear a negative charge (anions), while lithium ions are positive (cations). "For a battery that lasts longer, you need to move a greater number of charges.

How these proteins remove fluoride ions from the cell is poorly understand. To glimpse into the inner workings of these proteins, researchers in Christopher Miller’s lab at Brandeis University in ...

Fluoride's 8x improvement in energy density won't be very useful, for example, if the battery lasts only a fraction as long as a lithium-ion cell (at the very least, this type of issue would ...

For fluoride-based batteries to operate at room temperature, fluoride ions would need to dissolve better into a liquid electrolyte, like lithium ions do. The technology could then move toward ...
