Li-ion batteries fully charging in just minutes? Why not, say South Korean researchers

Li-ion batteries fully charging in just minutes? Why not, say South Korean researchers
A team of researchers at the Ulsan National Institute of Science and Technology in South Korea thinks it can leave its mark on technology by developing a kind of li-ion battery that can be charged in just minutes, instead of hours.

You know how annoying it is - having to wait for a few hours until your mobile device is fully charged. And what if your phone's battery dies and you don't have enough time to charge it to a decent level? Well, you probably end up turning off 4G/3G, location and data services and such kind of stuff, but you'll still be nervous, looking at that battery meter every few minutes.

It looks like this kind of experiences may soon be left in the past, as the new carbonized li-ion battery may dramatically shorten the time needed to fully charge your device. Current batteries are built in such a way that doesn't allow the charge to reach every part of the battery directly, which introduces this big delay that we have. The technology developed by the South Korean researchers involves the placement of the battery cells in a special graphite solution, which causes carbon to permeate the battery materials. This carbonization of the battery obviously creates a dense network of conductors throughout the electrodes of the battery, ultimately allowing for faster charging.

Sadly, it isn't known yet what kinds of devices will be able to take advantage of this new type of battery and if phones will be among them. What's probably even worse is that it isn't known when this technology will become commercially-available.

Wish some manufacturers take it from here to success.

imagine this technology in the Droid Razr maxxx, super long battery life and it charges in minuets! id jump ship and get verizon then.

This sounds like the technology is better suited for cars b-c of big size.

Manufacturers will be stepping up to commercialize the technology. It's too compelling not to. Also, size shrinking is just a matter of time. Transistors started out as being the size of a penny (height and width - !) for a single transistor.

I think this technology is much more useful for cars, for phones there are many ways to extend the battery life, the simplest thing is make the battery removable.

Yeah me too. But when are we going to see LiFePo4? Li-ion is so last generation. Airsoft guns and remote control cars are already there. I have a LiFePo4 battery for Magpul Masada PTS, and it's such better than my Li-ion battery. We see the hardware tech going from single, to dual, and now to quad core. Things are getting better and better on the hardware front. It is time for batteries to catch up.

I'm glad I clicked on the source to find something that was actually worth reading.

This is good news for future power hungry phones, laptops and tablets :) Full charge within minutes will be such a advantage!!!

Most demanding technology right now

They better patent this right now before Apple steals it and makes it as if it was their idea.

If this is Korean Manufecturer coming with this kind of battry they should register their patient other wise apple if apple get chance they wont hasitate to sue them too about copying there idea.

Six or more months ago, researchers at Northwestern University claimed they discovered a means to re-design Li-Ion battery technology to hold ten times the power currently possible and charge fully in a fraction of the time. So, the team at Ulsan National Institute of Science and Technology are a little late to the party. Now only if they could figure out how to make the batteries without rare earth metals...

Wonder if we are looking at a patented (after stealing) version of this called iBat (iBattery) (well by who is anyone's guess).

How bout the xperia s.. charges less than an houR!

Now this is what "innovation" is all about. Not just some stupid remake versions of former technologies like... (*spits on the ground) what Apple does.

Won't see this for years, can't displace the multi billion dollar industry without some push back. Just like the oil industry. It's so hard for the world to change for the better without getting someone pissed off about it and possibly losing money,.
