Are fluoride-ion batteries a post-lithium ion battery system?

Fluoride-Ion Batteries (FIBs) have been recently proposed as a post-lithium-ion battery system. This review article presents recent progress of the synthesis and application aspects of the cathode, electrolyte, and anode materials for fluoride-ion batteries.

Are fluoride ion batteries an alternative high energy density battery system?

Hence, batteries based on fluorine electrochemistry, the so-called fluoride ion batteries (FIBs), have recently been deemed as an alternative next-generation high energy density battery system. This article reviews the recent progress in FIBs based on liquid electrolytes. The mechanisms, advantages, and drawbacks of FIBs are discussed.

Are fluoride ion batteries a challenge?

Challenges and perspectives Being an infant technology, FIBs experience many challenges in the way of their development. There are many challenges associated with each component in FIB viz. cathode, anode and electrolyte. As a result, fluoride ion batteries are yet to achieve the energy density and cycle life required for practical applications.

What is a fluoride ion battery?

Fluoride ion batteries (FIBs) exhibit theoretical volumetric energy densities, which are higher than any of the lithium or post‑lithium ion technology under consideration and they have recently stepped into the limelight of materials research as an ideal option to realise the concept of high energy density batteries at low cost.

Are fluoride-ion batteries the future of energy storage?

Although lithium-ion batteries have transformed energy storage, there is a need to develop battery technologies with improved performance. Fluoride-ion batteries (FIBs) may be promising alternatives in part due to their high theoretical energy density and natural elemental abundance.

How does a fluoride-ion battery maintain charge neutrality?

Batteries release energy as electrons move from a material with a high Fermi level (anode) to one with a low Fermi level (cathode). In a fluoride-ion battery, charge neutrality is maintained by the concurrent removal of fluoride ions from the cathode material and insertion of fluoride ions in the anode material (Figure 2).
