Ten-fold increase in battery life could be possible with new electrode technology

Ten-fold increase in battery life could be possible with new electrode technology
While the displays, processors, and all the bells and whistles our mobile devices come with have been getting noticeably better and better over time, the batteries that power our gadgets do not seem to be treated with the same attention. However, here comes a team of researchers from Northwestern University that breaks that rule and focuses on delivering a battery with performance we can only dream of at this time.

The folks have developed a lithium-ion electrode that should enable traditional li-ion batteries, the same type that the great majority of contemporary cell phones use, to have ten times as much capacity as they do today. Furthermore, a battery that uses the special electrode would still be five times as efficient even after 150 charging cycles, which is about a year of regular use.

So, where does the magic lies? In a nutshell, the electrodes of a modern lithium-ion battery are made out of graphene sheets. Silicon used for the same purpose may superior to graphene, yet its expanding and contracting during the charging process renders it practically useless. The guys came up with the idea of constructing a battery electrode composed of both silicon and graphene sheets in order to minimize the silicon's unwanted behavior. Besides, holes with diameter between 10 and 20 nanometers were drilled through the sheets of graphene, which allegedly can speed up the battery's charging time up to ten times. 

Of course, do not expect finding this technology under your smartphone's back cover anytime soon as it has yet to be perfected. Besides, it is still not clear whether it will be cost-effective enough to be marketed. On the other hand, it is surely nice knowing that researchers are working hard on pushing the boundaries of batteries even further, and we sure hope that the battery life of a heavily-used smartphone will soon be measured in days, not hours.

That will be the next great innovation in smartphones. We have processing power (dual and quad-core) ; we have HD Amoled screens ; we have thinness ; what we have not is battery life. Imagine your iPhone 4s ; Galaxy Nexus ; Bold 9900 or Lumia 800 lasting one week. Very cool.

What is rare is style, comfort, security, durability and age sustainability... Some of these are based on my opinions so you might totally disagree. What do you people think?

Put this in LG Nitro HD for AT&T and I pay you the price as if I bought two of them with a promise of Ice Cream update

lol not to knock the dream but i'll believe it when i see it. . . there have been so many technologies taht sound potentially game changing but never got through,. anyone remember racetrack memory? ok how about Bubble memory? exactly. although this is what we've been waiting for since smartphones really took off... well... if it's too good to be true; burn it at the stake.

I absolutely agree. Over the many years I have been in the cell phone industry, I have read about many battery technologies that COULD be the big next breakthrough for increased battery life. None have ever panned out as of yet. So, I will agree and say I will believe it when I see it.

stop talking about it only do it! I've been hearing about his new everlasting super duper cells for a long time. We got dual/quad cores, 720p screens, 12 mpx camera unit, LTE but we STILL HAVE CRAPPY BATTERY which are not enough even for one day in most cases!!!!!!

if they can invient something like this why dont they put in cars? i bet i can use this new type of battery in my AIRSOFT gun

Well first off the batteries used in cars last a lot longer than your average Li-ion battery does, but it would be a pain carrying around something like that on a daily basis. Secondly if and when this technology gets perfected I'm sure you will be able to use it in many diff types of applications, such as your precious AIRSOFT gun, but I'm sure that will be quite some time from now and you may grow out of playing with toys by then. Lol

Now with this Apple can start adding 4G without battery sacrifice

Battery energy density affects all manner of applications, from cell phones to electric cars. The first one to crack this nut with a cost-effective solution will hit the jackpot like never before. The Northwestern U. team may be knocking on the door....

There have been announcements like this for the past decade, yet all of them have never seen light... Don't want to sound like a conspiracy theorist but do you know how much money companies will lose if batteries lasted for a week instead of a day? Just some food for thought.

Sad, but true. Look at the Oil industry.. there are all kinds of conspiracy theories about how oil companies have bought up electric patents and paid inventors to keep quiet.. to keep oil mainstream as long as possible. I really don't see the same thing happening with battery technology however.. as a new technology will cause an explosion in tech sales. I think right now the current battery tech is holding back innovation.. a battery that lasts 10x longer... I imagine companies will open the floodgates with products that can tap into the extra power.. until we're back at these NEW batteries lasting only 1 day! I think a new battery technology is just a win win for consumers and companies alike.

True because in the philippines... i watch on the news that a Filipino invented water powered car... using the water as a fuel.... then he was gone after that...

I heard this kind of news many times over. Now even latest devices still using old lithium battery. Just bring it on will ya.

If the RAZR has this new extremely thin battery technology why can't they just cram two together to make it double the battery life but a "normal" sized battery. I would take a RAZR the size of a Bionic with double the battery life... Just sayin'...

then it wouldnt be a "razr"

It just wouldn't be quite as thin as the RAZR... there are other selling points.

Because it won\'t work. You cannot just put together two batteries and make them work. It has its limits. What...capacity about 4.000? And then put another one and make it 6.000? And so on and so forth. They need new technology to make batteries last longer.

Wow ten fold that's innovation andbbig lift..... two/ three weeks on stanby andbtwo days of use.

If it can really offer upto 10x the battery life than \"triditional\" Li-Ion batteries, then I could see about 150 charging cycles in a year, but as of right now I\'m doing at least 365 charging cycles in a year.

Agreed, some days i charge my phone multiple times especially when using the hotspot or playing lots of games.

It's about damn time someone started focusing on a solution to a better battery!!

After my rather irritating stint with my Thunderbolt, I am starting to careless about all the features and abilities of the phone and is much more focused on getting some honest to good battery life. Or else what is the point of having a phone like a super computer if it only lasts 20 mins a day before i need a charger. Battery tech is worse than 3D geez

Here what i want a 2000 mah battery in a thickish phone with a 4 inch screen and a 800 mhz optimized quad core. The battery life would be great. O yeah and a super amoled non hd.

Do you have the recent gingerbread update on your thunderbolt? I generally get anywhere from 12-15 hrs a day on mine...

Like someone said before...it reminds me those conspiracy theory about oil companys...BUT! If they are able to make ultra thin chassis, 720p screens, good camera unit (I remember one of my first phones...siemens c75 I believe...it had a detachable camera unit. Well, that was something amazing!:D)...why do they focus on battery NOW? beause they made more powerful processors and realized that those tiny batteries are just not big enough. A little bit too late. They do it for their own comfort, not ours.

Good News. The Battery on my EVO Sucks. To quote Football Coach Pat Fitzgerald... " Go CATS!"
