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.

Don't you think we're due in time for a battery breakthrough? It's been a while. And no, 4000/5000maH batteries are not a breakthrough. I mean an actual breakthrough. Everything is rapidly progressing except battery tech.

it is overdue. the reason why battery tech is taking a long time they any other tech is because it involves a lot of chemistry and different types of testing in order for it to be stable to sell to consumers. No matter how much a company gives to R&D battery tech is going to take a lot of time for that reason. While articles like this and others say the progress for battery tech is finally coming up but it will be a couple of years before testing really comes to reality.

Yep, we are talking about stuff that if it´s not safe it could start burning and/or explode and worst case kill people.

Every few months there's some report about some University or another discovering a battery breakthrough. But nothing ever comes of it.

Yeah. Almost all of them has some grapheme here and there but none has seen the light of day so far. With battery tech, I guess stability and safety comes first

just ignore all those university invention, they just wont made it to mass production, all we can hope is some R&D team from big company invent new battery type.. Li-ion and Li-Po already used for decades, and all they do is increase the density of capacity and charge rate, and thats all we need for now :-/

Take a chill pill and while you're at it, how about you put a knife into a LiPo or LiOn pack and then you'll instantly appreciate just how volatile these things are as well as just how much real world testing is involved to get these battery tech advances to market with a high degree of safety. IMO we're at least another 5-10yrs off using this tech, so strap yourself in for the long haul.

Finally something worthy of a patent.

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

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.

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

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.

So in the meantime lets support replaceable batteries.

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

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:

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.
