Supercapacitors !!

Assalamulaikum.. how are you guys? i am SUPERB fine.... hehehe..  it is because, i am at home now!!!!! this holiday actually i decided to stay at Sabah since i got final year project to be done and need to start earlier, but at the last minute decision i travel back home but only for 1 week. its ok i guess, i am still enjoying my vacation..(chewahh)....

So.here i am, at  nice room comfort with cool air (aircond) and nice bed as it was. Home is like heaven! i sleep more than 8 hours a day!! don't blame me, its too comfort here. hehe...after two days i am back now was the first time i open my blog and decided to write something.. this is because there is much more things more interesting to do instead surfing the internet all day, like i usually do...

Yesterday, my sister do some birthday party for her first son,Mohd Irfan Daniel for him becoming 1 years old. i bought 1 pair of clothes to him.My first sister also come, kak long and her family and also some friends of my mom... we eat and laugh happily... Then as usual all my nephew ask me to bring out laptop because they wanted to play games.. Then i bring it out, without charger, just using batteries.. 

After a few hours, they come to me again and ask to switch on the laptop back... i ask, why?? then they said that my laptop turnoff automatically... then i realized, i just let them use the laptop by batteries, of course it does not stand too long. 3 hours for maximum time.. then i get the charger, plug it and then all of them happily playing games again.. nice to see all the kids happy.... :)

After a while, i started thinking... what if the we can get a batteries that can last long, for maybe all day? this problem of electric capacity had been practically on research for so many years. and of course, year to year they do get some improvisational and the batteries  technology is developing intensely. However, such all the research had been done, they got the higher energy capacity, but also requires a lot of time to charge it. The matter of time is really as an impact for people nowadays because time is very limited.
battery low!!
Then I search and discover some new research that they find a way to store electrical remarkably high storage capacity while retaining other attractive attributes such as superfast energy release, quick recharge time and a lifetime of at least 10 000 charge/ discharge cycles.
"Those properties make this new form of carbon particularly attractive for meeting electrical energy storage needs that also require a quick release of energy -- for instance, in electric vehicles or to smooth out power availability from intermittent energy sources, such as wind and solar power," said Brookhaven materials scientist Eric Stach, a co-author on a paper describing the material published in Science on May 12, 2011
It was called as SUPERCAPACITORS!! Supercapacitors are similar to batteries in that both store electric charge. Batteries do so through chemical reactions between metallic electrodes and a liquid electrolyte. Because these chemicals take time to react, energy is stored and released relatively slowly. But batteries can store a lot of energy and release it over a fairly long time.

Supercapacitors, on the other hand, store charge in the form of ions on the surface of the electrodes, similar to static electricity, rather than relying on chemical reactions. Charging the electrodes causes ions in the electrolyte to separate, or polarize, as well -- so charge gets stored at the interface between the electrodes and the electrolyte. Pores in the electrode increase the surface area over which the electrolyte can flow and interact -- increasing the amount of energy that can be stored -Yanwu Zhu et all


many types and design of capasitors



how its works

Therefore,maybe with this new technology we no need to worry that any of our electrical device run off of battery... no need to worry when we go travelling, our handphone got low batteries, trouble finding place with plug available to charge it, no more.... !!!! this prototype still in test, but somehow maybe after some few months or a years its will be in a marketplace... who knows? 

Thats all from me today.. happy holidays for those having it right now.. may peace upon you all!!! :)

p/s: after this product release, no need to worries your gps run off battery dear.. :P
p/s 2: hopes i can stay more longer at home... plzzzzz... (blink2 eyes) :P
