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.

Now, let's subsidize the crap out of this thing. Since the Govt. wants to hand subsidies out like candy, these guys should get one. Batteries are practically the equivalent of HDDs, advancement wise. They need a new killer-app to set things on fire. If we want a smart phone that can spend more than one day away from the charger, this is necessary. PS -- I want this very much! If we want a car that can drive with zero emissions, haul a family, the dog, and camping gear, this is necessary.

Thats what univerities are for.

Really: Universities are government sponsored R&D labs. If they [or the researchers there] bothered to patent anything, between them and DARPA, there wouldn't be any product left to sell.

Many things discovered in University labs are patented, often before the research papers are published. I definitely know of a company that I have worked with that was spun off from a major University just to hold patent rights on some of the research.

Seriously, Steve Jobs took most of his initial ideas from academia. If university r&d patented everything, there wouldn't be Apple Computer ;)

Just because batteries can make phones last longer from the wall, doesn't mean they will.

More than likely, they'll just give a more beefed-up, power-consuming chipset. They'll be able to add GPUs/CPUs that require even more power, better GPS/Radio antennae that are more accurate, stronger WiFi antennae, and more RAM/HD space. At least, until they hit the heat restriction wall, or space constrictions,... and then they'll leave the rest for recharge life cycle.

If the latest Kal-El CPU is an indication, they're finally starting to do it right. Kal-El is marketed as a quad core, but it actually has 5 cores. The fifth core is a low power/low power consumption core which is used when the phone/tablet is doing anything not needing the power of the four regular cores.

So the phone uses the regular quad cores when you do anything CPU intensive, but uses the low power consumption of the 5th core when the phone is idle or doing simple stuff.

Are you quite sure your government would subsidize a German university..?

Look at where some of the "stimulus" went to answer that question. Billions went to companies outside the US.

In case you just woke up from a 65 year coma, World War 2 is over; Germany has been a peace-keeping nation since. I don't see why investing in R&D should have a geographical or political stipulation attached to it.

ARE YOU DOING DRUGS???

Why would US taxpayers subsidize R&D in a foreign country where they will take out patents and build companies there to come back and take more American jobs?

Why would ANY country subsidize that? Hey, it's just the way the world is setup. If there were no country boundaries then it wouldn't matter, but you're talking about transferring wealth from one country to another on the taxpayer's backs!!!

Life doesn't fit cute little "let's all play nice together" scenarios.

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.
http://en.wikipedia.org/wiki/Delft_University_of_T...
http://en.wikipedia.org/wiki/University_of_Twente
http://en.wikipedia.org/wiki/Eindhoven_University_...

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.
