New research may enable 300% faster charging times for lithium-ion batteries
About the only interesting thing we have seen out of batteries lately on a commercial level is how LG was able to design a curved cell for the LG G Flex. Other than that, the density and chemical design for lithium-ion batteries is getting real long in the tooth.
However, there has been a breakthrough at the University of Tokyo which may have discovered a new candidate to replace the current configuration of electrolytes currently used in lithium-ion cells. Researchers have found this new electrolyte to exhibit high reactivity and resistance to degradation, both properties that bode well for high performance batteries.
This chemical make-up uses a solvent that is four-times more concentrated than what is currently used. The new mixture should be able to establish a new line of batteries that can recharge faster, and discharge more power per unit time. If recharge times are reduced to one-third of normal, we can also expect voltage to increase from 3V to 5V.
The work being done by the University of Tokyo, along with the University of Kyoto and Japan’s National Institute of Materials Science is aimed at automotive applications and providing better power cells for electric cars. However, these advances will certainly make it consumer electric battery applications for products like the smartphones we dig so much.

Research research research! When are they ever getting implemented, when are the users getting their hands on it? This question begs for an answer.

Exactly, every few months we see article claim major battery improvement tech, yet we still don't any phone using any of the tech
Hopefully OEMs shift their focus to battery life this year :)

Check thunderpowerrc.com for their G8 Pro Force 70C batteries.
These batteries can be charged at 12C. That means that they can be fully charged in 5 minutes. They've been available for over a year. A 1000mAh battery can be charged at 12 amps for 5 minutes for a full charge and a 2000mAh battery can be charged at 24 amps for 5 minutes for a full charge. This is over 20 times faster than my cell phone charges right now. The only problem is that those tiny wires in my USB port will burn up instantly with that kind of current. But, you could remove the battery and put it in an external charger, go take a crap, then come back, put it in your phone and off you go, all charged up.
These batteries can also discharge at 70C. That means 70 Amps of output power for about 51.5 seconds.

THIS is what we actually need!!!
Not more cores, Extreme resolution screens or faster clock speeds

Agreed, we don't need those stupid 4K video, "smart" grimmicks, 999 mp camera and etc.
All OEM should focus on enhancing the power efficiency instead

research is made in tokyo = in future xperia phone? :-D

this is just suggestion but how about we research something better and more efficient then Li-ion batteries i mean that would revolutionize the portable world handhold consoles phones equipment etc.... charges faster lasts longer due to the way it handles whatever substance it uses to charge i mean Li-ion batteries have been around since a long time ago !

The question is: How many charging cycles will the battery last?

The thunderpowerrc.com G8 Pro Force 70C batteries that I've been using in my RC helicopter have handled over 50 charge cycles so far with no apparent degradation in performance.
What upsets me is that I bought these batteries a half a year ago, and they've been available for a year now and my cell phone still takes 2 hours to charge. Why? The technology is there already, why isn't it in my phone yet?
