Lithium-oxygen batteries can provide five times the capacity of lithium-ion cells

Lithium-oxygen batteries can provide five times the capacity of lithium-ion cells
Power users rejoice. A prototype of a new smartphone battery using lithium-oxygen, provides as much as five times the power as the current lithium-ion cells used in today's smartphone units. One of the problems in developing the new battery is that lithium-oxygen is "thermodynmically unstable." That doesn't sound like a phrase you want describing the chemicals that are powering the device in your hand. 

But at the U.S. Department of Energy's Argonne National Laboratory, a new discovery has found a way to "produce stable crystallized lithium superoxide (LiO2) instead of lithium peroxide" while the battery discharged. Lithium-superoxide breaks down into lithium and oxygen allowing the battery to be more stable and efficient with a long life-cycle. In addition, the new discovery means that the cell won't be an open system requiring extra oxygen from the environment to be pumped inside. This is another factor making it not only safer and more stable, but also economical.

Despite the new breakthrough, don't expect to see the lithium-oxygen batteries powering up your handset just yet. More research still needs to be done before smartphone users can take advantage of this next wave of powerful batteries.

And oems will just keep shaving the thickness out of over-all build in flagship phones instead of placing long-lasting batteries. In marketing world, thinner phone is a number one priority.

is it rechargeable? since it say it will break down to Lithium and oxygen when discharging, and I dont think electricity can reverse that reaction :-/

Well, it would be quite pointless of them to research a battery that isn't rechargeable so I'll go out of my way and say that it is.

For now, the best we can have is 4000mAh.

Be it bigger capacity or faster charge time, those discoveries—and no foreseeable implementation—has been the theme of the last decade or so.

Guys stop with the childish bickering about Apple and Samsung it doesn't matter, neither have gone all out to solve this in all fairness, the last few years they have all depended on processors using less battery!

Hope this doesn't mean smaller batteries for Slimmer phones..... Hope you can hear samsung :p

Even though Samsung has slimmer phones, there batteries are still larger than any OEM who has a phone of similar size with very few exceptions. Dimensions - 153.2 x 76.1 x 7.6 mm (6.03 x 3.00 x 0.30 in) VS 158.2 x 77.9 x 7.3 mm (6.23 x 3.07 x 0.29 in). Battery - Non-removable Li-Po 3000 mAh battery VS Non-removable Li-Po 2750 mAh battery (10.45 Wh) I think you're calling out the wrong OEM. You need to look at the facts. Plus Samsung has this:http://www.androidauthority.com/samsung-doubles-lithium-battery-capacity-620330/

Yeah Samsung is actually quite good at fitting a decent sized battery into small phones. For example, Galaxy S6 (2550 mah): 143.4 x 70.5 x 6.8 mm HTC One A9 (2150 mah):145.8 x 70.8 x 7.3 mm

Because they can't get away with a smaller battery. I suggest educating yourself in the way Android and Java work.

Yea I really hate when Meizu Pro 5 lasts longer than iP6s+. The more you know.

26. Unordinary unregistered

How's the Galaxy Note 5? Forgot since it really wasn't that impressive. After all, we were talking about Samsung, bb :*

I was expecting an explanation on how Java is bad. Am I wrong?

29. Unordinary unregistered

Battery life would be leagues better if they didn't use Java. Go do some research. Also funny that I didn't even mention any form of Apple or the iPhone, lmfao. Typical butt hurt response. It's ok bb, I still love you :) Mwuah

Whatever happened to Samsung breakthrough that was gonna allow them to put a 4000mha battery into a phone the size of the note 5? They said it would be in production by this year

18. SenorThrottles

Well they were able to fit a 4000mah battery into the A9 which is slightly bigger, but thinner than the Note 5

So in the meantime lets support replaceable batteries.

All these new battery breakthroughs to bad we won't see them in phone for 2-5 years.

yea cause it will take that long to test and find a stable medium in order to be safe for mass production. I know a lot of people want battery tech immediately like it is easy to develop new battery tech. but doesn't realize how much testing and research it involves to make them. i am sure in due time it will happen

24. Arch_Fiend

Yeah it takes years to test/develop the life cycle so I understand why it takes as long as it does to develop new battery tech.

Yeah, but for the past 10 years we keep hearing about breakthroughs that never materialize. LiPo an Li-Ion are OLD technologies, something should have been possible to commercialize... I'm getting pessimistic about ever having good batteries.

Just another promise of a battery breakthrough that will never see the light of day. Sigh...

10. korean411

if they find a stable medium then the new battery tech will eventually see the light of day after numerous testing. Battery tech is going to take a long time to develop because designing it involves a lot of chemistry i hopes to find a way to be safe and stable for consumers to buy.
