New long-lasting 'battery' can charge in seconds, doesn't degrade

Recommended Posts

This one is one to watch as it may move quickly to an IPO once capable of production.


From cell phones to EVs everyone has wanted a fast charge and long lasting battery. These super capacitors are even flexible.


If this battery breakthrough makes it beyond the lab, waiting for a smartphone to charge could be a thing of the past.




"Scientists have developed a method for creating small, flexible supercapacitors that could mean blisteringly fast charging times and more reliable batteries.


While lithium-ion batteries can break after about 1,500 charges, this supercapacitor can be recharged 30,000 times before degrading, according to scientists at the University of Central Florida. Better yet, the supercapacitor can charge in a blink of an eye and wouldn't need topping up for a week.


Supercapacitors use static electricity to store energy, as opposed to batteries which use an electrochemical reaction.


"If they were to replace the batteries with these supercapacitors, you could charge your mobile phone in a few seconds and you wouldn't need to charge it again for over a week," said Nitin Choudhary, a postdoctoral associate and one of the main authors of a new paper detailing the process.


The supercapacitors they've created are also flexible, which could help address one of the main pitfalls of devices such as the Apple Watch.


Their supercapacitors are packed with millions of nanometer-thick wires wrapped in two-dimensional materials.

"A highly-conductive core facilitates fast electron transfer for fast charging and discharging. And uniformly coated shells of two-dimensional materials yield high energy and power densities," the university explains.

Jung is in the process of patenting the method. However, he warned it could be some time before this technology is seen in electronic gadgets and vehicles.

"It's not ready for commercialization," Jung said. "But this is a proof-of-concept demonstration, and our studies show there are very high impacts for many technologies."

Supercapacitors aren't exactly new; I think the hook for this particular article is the fact that the ones being touted are flexible. Supercapacitors are already in use in some applications in lieu of batteries. I have some Honeywell timers that use them instead of button batteries as backups during power outages. Backup batteries tend to fail from disuse and you don't know it until you need them. Capacitors have longer lives. Here's the timer: https://smile.amazon.com/gp/product/B004AP92N2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1


Charging a capacitor is usually fast, but not instantaneous. If a capacitor is going to replace a battery with a particular amp-hour rating then it will have to hold the same amount of charge as the battery would release in that many amp-hours of use. So the speed of charging will depend on the apparatus used for the charging. High currents will be needed if a large capacitor is to be charged quickly.

Fast discharge rates can also be dangerous. Batteries have some internal resistance which limits their peak discharge current. Supercapacitors don't. They make great firestarters if their output is accidentally shorted.

Agreed guys, and known, as that is why they are talking about starting with smaller applications like cell phones. I remember when everyone "out there" talked about how all Lithium batteries will burn up in cars because of the capacities involved. The article is talking not just about the bendable aspect but that the bendable makes it more flexible for smaller applications. And that it is not yet ready for prime time.

I post related technologies here that I find in my reading are in development and have the potential to be disruptive (Profitable). Some fizzle out - others don't. I will watch this one develop.


As we've seen recently in the Samsung S7 Note phone explosive fires, and when Boeing had a serious issue with lithium batteries exploding, and declined help offered by Musk causing more time grounded, any strong storage and rechargeable system can, when poorly manufactured, cause issues. Of course Musk and Space X are the antichrist as it were with the ULA members. Even if he can help them.


I have done basic electronics guys. I know capacitors are nothing new. I built the GR2000 Heath kit electronic tuning TV in 1972 doing the Devry Institute Bell and Howell home study course. The most important thing I learned is that I love modules and despise component level repairs. MY Samsung 52" LCD TV way back had a capacitor problem and blew the tops off which they repaired out of warranty. I believe those were of the same batches as the infamous now Dell cover up of their massive failures of enterprise desktops from the same issues. I don't remember any of those smaller circuit board failures cause any explosions or fires in my TV or the desktops.


I posted here six years ago and before about the Samsung capacitors and the Dell cover-up from 2003 - 2005 and posted again when they finally admitted and settled in 2010. I would not do biz with Dell for a while. Until 2014. Now I have two of them, a Venue 11 Pro tablet and my aging 2014 XPS 2720.


Samsung capacitors:



Dell capacitors.



I am waiting for delivery of my new Moto Z Play phones with fast charging since Microsoft let all us Windows phone owners down. Verizon is offering them as free no trade in upgrade and new account phones until Sunday. The S7 for 10 bucks a month for 24 months no contract renewal required.


I did have one fire when the power center and surge protection blew from a bad power supply at a friend's house. It did catch fire and I was able to pull it out of the built in nook I built in the first rig for it and threw it out to burn out safely.


I also had a oil filled electric heater do the same when the circuit board under the controls caught and same thing, threw it out.


My wife still smokes so I got her a vape mod that uses 18650 batteries that come from China both with protected circuitry and without (cheaper.) I use 14500 Lithium batteries in my Cree LED high lumen flashlights. I use Trustfire protected 14500 Li-Ion batteries, as well as protected 18650s.


From the exploding/burning Li-Ion Hoverboards to the Telsa cars and PowerWalls, cheap isn't acceptable.


I expect the new tech storage technology to have bad imitations. But I doubt any of the previous capacitors used Graphene and nano tech in their construction. Of course we all know these bring with them their own set of control issues to overcome.


Heck I use rechargeable batteries that hold 80-90% of their charge for a year, and yes I spent a bit on a Nitecore D2 LCD readout charger. I remember the early NimH batteries that did not come pre-charged and hold their charge like the new breed does. Most non RVrs are not even aware of pre-charged rechargeable batteries, except for some with Eneloop 1900 mAh batteries. I use Imedion by PowerX 2400 mAh and have a charger that reconditions them. I still have three Eneloop batteries that are still going strong after five years in use. https://www.amazon.com/Powerex-MHRAAI4-Imedion-Rechargeable-Batteries/dp/B003LWMZ5M


Now I am looking at the flexible capacitor and I am sure like Li-Ion, there will be cheap knockoffs as well as performance well made products. Remember when Japanese was considered junk? Remember Goldstar cheap junk which most can't comprehend is LG (Lucky Goldstar)


If there is money in it, development will happen. We'll see. Worth watching I think. Batteries and high capacity storage are where more money is beginning to go.


Remember this from last April? https://news.uci.edu/research/all-powered-up/



“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” said Penner, chair of UCI’s chemistry department. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”


“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most.”


I am still seeing Power utility companies using the stabilizing problem with adding micro grids and posted this here in 2015: https://cleantechnica.com/2015/02/27/irelands-first-combined-ultracapacitor-energy-storage-facility/?utm_source=Cleantechnica+News&utm_medium=email&utm_campaign=727030b6d2-RSS_EMAIL_CAMPAIGN&utm_term=0_b9b83ee7eb-727030b6d2-331970081


And this in the recent past: http://www.eosenergystorage.com/opportunity/ Musk is not the only one that sees that energy storage is the future. Generating cheap energy is easy today, and, as the Germans are demonstrating, that renewable energy plants are cheaper to build with no further money output for energy input from fossil fuels.


We've seen what happens when real science butts up against pop science.


This is extremely intimidating to the oil barons and their subsidiary high cost electric energy coal suppliers who are usually the same folks.


I posted this here in 2013 : https://www.cnet.com/news/new-teeny-tiny-battery-charges-in-less-than-a-second/


I bet some of it becomes ready for prime time in my lifetime. :)


On edit: Lou thanks for the switch source. useful for security too!
