Fluoride battery has potential to hold ten times more energy than lithium battery

Few things hold as much potential to change a wide variety of devices for the better than the battery. Batteries with higher power capacity will allow for gadgets like notebooks and smartphones to operate longer away from an outlet. Higher power densities will allow a longer driving range for electric cars as well.
 
Researchers at the Karlsruhe Institute of Technology (KIT) have made a battery breakthrough that promises to increase energy capacity significantly.
 
The researchers developed a new concept for rechargeable battery that needs no lithium and can hold many times more energy inside than existing batteries. The new battery concept uses fluoride and is based on a fluoride shuttle that transfers anions between electrodes. Since the battery doesn't need lithium, they are also safer.
 
The concept was presented in the Journal of Materials Chemistry by Dr. Maximilian Fichtner and Dr. Munnangi Anji Reddy.
 
The new concept can be used in batteries in two ways. They metal fluorides can be applied as a conversion material in a lithium-ion battery and can be used to create batteries needing no lithium at all. The lithium-free batteries can store more energy at a lower weight using a fluoride containing electrolyte. In that form of battery the fluoride anion takes over charge transfer from the lithium cation.
 
Dr. Fichtner said, "As several electrons per metal atom can be transferred, this concept allows to reach extraordinarily high energy densities – up to ten times as high as those of conventional lithium-ion batteries."
 
The researchers are tweaking the design right now to work on further development and architecture. The goal is to improve the initial capacity and cyclic stability of the fluoride-ion battery.

My uncle works as prof. at the TU Delft (TU Technical University), (aerospace department) and they get funding from all over the world, also he has 17 patents on his name, (owned by the university), and I believe they, if i remember correctly, the TU owns about 2000 patents in total, and they make up for 55% of there funding.

Its a little bit older then MIT, and 1.5x bigger, but it has basically the same function.
http://home.tudelft.nl/en/

We have 3 TU's working closely together, and totaling about 2.5 times the size of MIT, and they have a together a legal/financial department that has 2 goals, patent the developments by the TU's and get the most out of them (and doing this now for all research of all the university's country), and find funding for research, from ware ever they can find it.

Now a days university's do most of the fundamental research, like in this example, and next to government funding battery making companies donate money for projects like this, its a win win win for all!
1. the University get money to buy equipment so it can teach cutting edge tech.
2. companies get license that tech and cheep researchers. (profs don't make that mouths, and students are basically free)
3. Students get to learn the the latest tech.

Next to that lots of tech university's work together with other university's, so government funding from a co-funded research project can have money flowing in a foreign university, and knowledge flowing back.

As some university's are ahead of other but then can lack the funding to further there research, and they then take the money ware they can get it.
