"A team from the National University of Singapore's Nanoscience and Nanotechnology Initiative (NUSNNI), led by principle investigator Dr Xie Xian Ning, has developed the world's first energy-storage membrane.

Electrical energy storage and its management is becoming an urgent issue due to climate change and energy shortage. Existing technologies such as rechargeable batteries and supercapacitors are based on complicated configurations including liquid electrolytes, and suffer from difficulties in scaling-up and high fabrication costs. There is also growing public concern and awareness of the impact of traditional energy sources on the environment, spurring a continued search for alternative, green, sustainable energy sources.


Cost-effective and environmentally friendly


Xie and his team have developed a membrane that not only promises greater cost-effectiveness in delivering energy, but also an environmentally friendly solution. The researchers used a polystyrene-based polymer to deposit the soft, foldable membrane that, when sandwiched between and charged by two metal plates, could store charge at 0.2 farads per square centimeter. This is well above the typical upper limit of 1 microfarad per square centimetre for a standard capacitor.


The cost involved in energy storage is also drastically reduced. With existing technologies based on liquid electrolytes, it costs about US $7 to store each farad. With the advanced energy storage membrane, the cost to store each farad falls to an impressive $0.62. This translates to an energy cost of 10-20 watt-hour per U.S. dollar for the membrane, as compared to just 2.5 watt-hour per U.S. dollar for lithium ion batteries.


"Compared to rechargeable batteries and supercapacitors, the proprietary membrane allows for very simple device configuration and low fabrication cost. Moreover, the performance of the membrane surpasses those of rechargeable batteries, such as lithium ion and lead-acid batteries, and supercapacitors," Xie said.


The research is supported by grants from the Singapore-MIT Alliance for Research & Technology (SMART), and National Research Foundation. Dr Xie and his team started work on the membrane early last year and took about 1.5 years to reach their current status, and have successfully filed a US patent for this novel invention....

...Potential applications: From hybrid vehicles to solar panels and wind turbines...

There are alot of words in there that I don't understand ... but it sounds pretty neat, nonetheless :)

Yeah, huge problem facing the world is better energy storage. Good for the universities, I'm sure this could bring in a lot of money for research and to the inventors of this, people who work tirelessly and don't really make all that much money. Not that that was their purpose for doing this, positive research like that can ensure they get funding for the rest of their careers.

Now, somebody come up with something better than burning fossil fuel please

IN an nutshell, it means that the medium for storing energy just got about a gazillion times thinner, cheaper and can store about a gazillion times more energy before needed to be recharged. The possibilities for applications of this are unbelievable: electric cars that may go 5,000 miles on one charge of only 4 hours at a normal electrical outlet.... skuba diving suits with added heat elements that last for weeks instead of hours.... lighter and more components in spacecraft... the list is just endless.

Sounds pretty damn promising.

They are calling it a "balloon".

Who is they? if you are going to post, then please consider staying on topic.
A nine second video of someone releasing a balloon says absolutely nothing to us, other that to waste our time.

:whatever:
And I ask again, who is calling it a "balloon" and what is the purpose of the 9 second video?
If you really have something to contribute, I am definitely very interested.
Otherwise, stop spamming threads I create with worthless junk. Thank you.
