What is the basis for Toyota's fluorine battery claims?

In summary, Toyota is researching Fluorine batteries that claim to have 7x the energy density of LiIon batteries, as found in a Google search. However, according to a textbook table of reduction potential, lithium is actually higher than fluorine. The 7x energy density refers to the stored electrical energy for the same weight or range with 1/7 the battery weight. The achievement of this is not simply due to fluorine being gaseous at room temperature, as fluorine is not used for redox in these batteries. The energy density of a battery also depends on the mass of other substances required for correct operation.

TL;DR Summary
Why is Toyota researching Fluorine batteries when LiIon cell potentials are higher?
Google top result says Toyota is researching Fluorine batteries that they claim will have 7x energy density of LiIon. However my textbook table of reduction potential gives lithium as higher than fluorine. Any idea what they base their claims on?

Thanks

I got that far. My point is how do they achieve this? Simply by virtue of fluorine being gaseous at room temp?

Fluorine batteries don't use fluorine for redox, it is just shuffled between anode and cathode.

Besides, energy density of a battery doesn't depend just on the redox reaction involved, it also needs to take into account mass of every other substance required for a correct operation.
 

FAQ: What is the basis for Toyota's fluorine battery claims?

1. What is a fluorine battery?

A fluorine battery is a type of rechargeable battery that uses fluorine as the active material in its cathode. It is also known as a "fluoride-ion battery" or "fluoride-ion cell."

2. How does a fluorine battery differ from other types of batteries?

Unlike traditional lithium-ion batteries, which use lithium ions to store and release energy, fluorine batteries use fluoride ions. This allows for higher energy density and faster charging times.

3. What makes Toyota's fluorine battery claims significant?

Toyota claims that their fluorine battery technology has the potential to greatly increase the range and performance of electric vehicles, as well as reduce charging times. This could have a major impact on the future of transportation and energy storage.

4. What evidence does Toyota have to support their claims?

Toyota has conducted extensive research and development on fluorine battery technology and has published several studies demonstrating its potential. They have also built prototype electric vehicles using fluorine batteries and have successfully tested them on the road.

5. When will Toyota's fluorine batteries be available for commercial use?

At this time, Toyota has not announced a specific timeline for when their fluorine batteries will be available for commercial use. They are continuing to research and develop the technology and have not yet announced any plans for mass production or release to the public.
