New cell will double the battery life of smartphones as soon as early next year

Ask the average Joe (or Joanne) on the street which part of his or her smartphone he/she would like to see improved next year, and the answer would indubitably be the battery. So it is good news indeed that a spin-off from MIT, SolidEnergy Systems, has developed a battery that is half the size of the juicer employed by the Apple iPhone 6s.

The new battery will sport a 20% thinner anode than current batteries because of the thin foil used to make it. The electrolyte is a hybrid solid and liquid. with a solid layer wrapped around both the foil and a non-flammable liquid. Since the SolidEnergy battery uses the lithium-metal foil for the anode instead of graphite, it can hold more ions than the standard Lithium-ion cell employed today.

So the SolidEnergy cell has twice the energy density of current Lithium-ion batteries, meaning that it can hold the same amount of energy as today's smartphone batteries, but at half the size. Or, it can match the size of the current batteries and hold twice as much power. And using the non-flammable liquid makes them safer to use than the Li-ion cells, which are a threat to explode when punctured and exposed to oxygen.

Believe it or not, these batteries are ready to go into commercial production. They could be employed by smartphones and wearables as soon as early next year. Handset manufacturers will have a tough decision to make. Do they offer the same battery life on their phones, but open up room inside the devices for new features or to make them thinner? Or do they keep the battery the same size, but give their devices twice the battery life available on current models.

"as soon as early next year" It better be, new battery tech for the masses is long overdue.

Damn straight. Now no matter what atrocities Jony Ive commits while making next year's IPhone "more refined", battery life will still be better. (seriously Tim, do something about Jony's eating's ruining your products for me)

Can you believe he got to fat? That's what happens when you get lazy and celebrating how many people you suckered into buying the same design 3 times in a row.

I was with you up until that last sentence :D.......Yay, male bonding!!!!!

I have to admit, I couldn't help saying the last sentence. But it is true. Right? I mean the guy who designed the HTC Magic phones isn't at HTC anymore and he used the same design 3 times too. But HTC saw significant drop in sales. Because they were never thought selling many to begin with. But if 75M are willing t . Uy it twice, why not try three times? It's like Spades. You ever play? If so then you can agree that if you have the Ace, King and Queen of the dame suite, that it's 3 guaranteed books...right? But again I could resist.

But still, even if this tech got into smartphones next year, I still don't like Jony Ive's thinner is better, imagine an iOS on a huge battery, now that would be AWESOME.

I can't wait to see how excited Jony Ive gets about next year's new 3mm thick iPhone with 6mm camera bump thanks to new battery technology...

Yes me too, SO EXCITED, I love being able to chop onions with my phone :D /s

Sure smart phone manufacturers will use this tech to make more thinner phones than providing more juice.

The somewhat outdated Galaxy S5 is even better with a few spare already stellar 2800mAh batteries. Everyone regress if they will. Just like the so many who want communism in the U.S. - Must be all the drugs and chemicals in the food. Glad I haven't been stricken, though I would probably fit in more with the general population.

I'm experiencing bad battery drain on my marshmallow S5 and random half restarts Only lollipop I could get anywhere between 4-6hours SoT, now I'm lucky to get 3hr30

Don't know where you live, but I've seen no one that wants communism in the US, I'm in MN. Now Socialism, seen plenty that support that. I'm sick of sealed batteries and the never ending quest to make phones thinner.

True innovation right here. People always say make the phone thicker. I'm like no, come up with an innovative way to make the battery better. Boom, here it is! I like when companies challenge themselves instead of taking the easy way out.

Or, use this concept AND make the phone thicker, which would mean even better battery life.

I like ultra thin phones. It's always impressive how much they can squeeze in.

"Better Battery" Finally, an article on a topic I think most on this site will agree on!

Yep. The fight will come later with thinner phones versus longer life.

The problem is if these things ever come to fruition or not, I can't tell u how many similar stories I've read about better batteries being right around the corner for years now!

Many things are in development for years before they get leaked/released. This is great news.

Exactly. How many stories about a breakthrough in battery yield by a group of students at (insert university name here) that will be available in the next year. A year goes by and it's never heard about again. The last one was the story about the accidental finding having to do with, IIRC, using gold or silver for the anode instead of copper that yielded higher capacities in a smaller form factor. That was around a uear ago, no update since.

This guy knows what I'm talking about! Lol some of these next year batteries were like 3-4 years ago and you never hear about it again.

yeah right.. just ignore these kind of news and leave it to bigger manufacturer (who slowly but surely increasing their battery size) S6 (2550mAh) -> S7 (3000mAh) Note 5 (3000mAh) -> Note 7(3500mAh)

Better battery and better speaker.. we are on our way!

Not so much if the speaker is water resistant. That is like putting earmuffs on, and then wondering why you can't hear as well.

That is why phones come with headphones. So you don't have to use the speaker.a

Not mentioned is the recharge cycle life span if it's improve. or worse

This is welcomed technology but we really don't need thinner phones.

We only need more battery life, I know right?
