Supercapacitor technology could result in the battery of your dreams
posted by Alan F. / Nov 22, 2016, 5:21 PM
In theory, these batteries could be a power user's dream. Charge one up for a few seconds, and a handset will last a whole week without needing another charge. Because supercapacitors store power on the surface of a material and don't require a chemical reaction to create the power, these batteries can be charged quickly. The prototype can be charged more than 30,000 times and still act like new. Currently employed cells start losing power capacity after a period of time.
The team at UCF played around with concepts, one being the attachment of two-dimensional material only a few atoms thick to the supercapacitors .By allowing electrons to pass quickly from core to shell, it resulted in a material with high energy and power density that charges fast. UCF's Yeonwoong "Eric" Jung said, "We developed a simple chemical synthesis approach so we can very nicely integrate the existing materials with the two-dimensional materials."
These batteries are also flexible, allowing them to be used in wearables. One major caveat according to Jung, is that the project is not yet ready to be commercialized. "But this is a proof-of-concept demonstration," he said. "Our studies show there are very high impacts for many technologies."

This fills the weekly quota for "new battery tech that will never happen is found".

Especially since it has been mentioned YEARS ago... the URL below is from 5 years ago: http://www.instructables.com/i
Also in 2012 (see source below) advances were already made (and not yet commercialized) to charge e.g. car batteries significantly faster.

Hopefully is 2-3 years it's made more accessible. That way the phone I buy will utilize such tech.

Yeah. I guess we will carrying hand grenades for a while.

Capacitors are equally capable of explosive and rapid discharge. Anything capable of storing and releasing this energy with known materials will have issues. If you've never sat next to a capacitor that blows it sounds like a shotgun going off. The electronics will most always out-pace energy storage. The electronics will consume less and become increasingly smaller. The largest issues are energy storage, display tech. (currently back lights), and rf transmitters/wireless in terms of energy usage. The operational time can be increased by more then mere batteries. Bottom line: Put that much energy into that small a space and it will escape in an uncontrolled manner no matter the materials or engineering. So as long as dense storage is required, you are correct jeroome86.

Don't worry all the phone manufacturers will installs these but with just enough capacity to last one day but our phones will be thinner because that's what matters most... evidently.

I know capacitors can be charged really fast.. but AFAIK capacitors also discharged really fast;; did they found a way to discharge it slowly, safely, and within stable voltage? (I dont read it anywhere in this article)

We always get promised with new batteries but we never seem to get them made available, with All this modern times no one ever seems to solve the battery problems its Amazing

Why would they? With current tech (coupled with non-replaceable batteries) batteries are depleted so significantly after 500 charge-cycles that consumers are literally forced to buy new devices. If you re-charge your phone once every day then that is a life-expectancy of about 2 years. This fits PERFECTLY in the plans of consumer product manufacturers. So there is absolutely no reason to change that. However, you will see this tech sooner in military though...

Another battery tech which is likey to not make it in the hands of consumers anytime soon. Though it's promising and while nice in concept, nothing to get excited about at this point in time.
