Researchers, in collaboration with Toyota Motor Corporation, have worked on a new type of cathode material for all-solid-state batteries. They have reportedly improved the capacity per volume of the positive cathode for “all-solid-state fluoride ion batteries” to about three times that of lithium-ion batteries.
Reports revealed that when incorporated into a battery, it’s expected to have 2x more energy density than lithium-ion batteries.
The cathode material for all-solid-state fluoride-ion batteries (FIBs) delivers a reversible capacity of approximately 550 mAh/g. That’s more than double the 120–250 mAh/g typical of lithium-ion cathodes, according to a report.
Fluoride-ion battery to be part of practical EVs
The fluoride-ion battery is expected to be part of the practical use for EVs after a few years.
Researchers from Kyoto University use copper nitride in the cathode. Other materials, such as manganese and…
