Startup comes up with a revolutionary battery tech - same capacity, half the size. Will be making modules for Project Ara
So, just last month, Google announced the first Project Ara handset that will become commercially available later this year – the Spiral 2. Well, it will only be offered in Puerto Rico, as the company wanted a small market to start the experimental project on. Quick reminder for those, who might not remember – Project Ara is Google's attempt to build a modular smartphone – one that has its hardware neatly segregated in various replaceable panels, which can be freely switched out on the user's whim.

One of the major concerns for one such phone is the battery capacity – after all, a small module can only hold that many cells, and it was noted, as the Spiral 2 was announced, that it will offer 20% to 30% less battery capacity than other products of the similar range.

Well, that may well be on its way of becoming a non-issue. SolidEnergy – a startup, founded in 2012, has been hard at work, trying to improve the way modem batteries are made. The company has managed to develop a super-thin metal anode with twice the energy density of graphite and silicon anodes that are presently used. This allows the batteries to appear "near anode-less", reducing their physical size to half.

SolidEnergy says it will be ready to commercialize the revolutionary battery in 2016, and it will be aiming at the mobile markets first – namely, it will look to create a module for Project Ara phones, which will provide more juice in the same package, but will likely try to sell its product to other major manufacturers as well. Additionally, in 2017, SolidEnergy will look to extend its solutions to the electric car market.


Thanks for the tip, Giulio!

Finally some battery news are also coming.

Now we just need more 3000< mAh batteries in the size of a 2500> battery..NOT Smaller battery.

Let's double the battery and cut the size in half. Now, I'm excited for that :D Z3/4 with a 5,000mAh battery would just be sick... o.O

Z3 got an amazing battery life with 3100mAh....so 5000 plus 20mn SoC and....AAAAAAAAAAAAH I LOVE TECH! XD

wouldn't it be better to make a bigger battery with more capacity , like a 4000mah battery of the same size as normal battery.

either way the new obsession with Qhd and 4k will send battery life down to the dark age , until spec obsessed fandroids get educated about displays and how PPI isn't everything , battery life will always suffer.

And yet, with QHD the Note 4 not only gets better battery life than its 1080p predecessor (with only a. 625% larger battery), it gets better battery life than nearly all phablets (including the iPhone 6+, which it also gets better reviews than)

So who should I believe, you or reality?

this is huge! i am more interested in lithium sulfur batts (2017 ish). they are way more important to society as a whole. but these lithium 'metal' batts will work out just fine in the meantime.

I want them to get carbon nanotube tech to be viable and combine it with other advancements for a high capacity, small volume, and quick charging without the degradation (or minimize it substantially). Then add some discreet solar panels to the phone and you'd have one long lasting device. Increasingly efficient chipsets should be a given at this point.

The Note 4 has QHD and still has MUCH better battery life than Note 3.
Get a clue

yeah samsung has done one hell of a job in raising the efficiency of their panels. the bad thing about that is they don't sell those panels to other phone oems.

Sharp and LG can also make some very efficient panels, especially after further maturity. Sony as well.

Exactly. That panel is the reason why Z3 has some pretty good battery statistics.

wouldn't it be even better with FHD , no doubt from what I've seen samsung has done a good job with the note 4.
But
i'm jut saying how about choice one model with FHD and big battery and another to please the spec loving crowd,

to me battery life is more beneficial than a slight increase in display PPI and no. of processor cores.

You've got people griping about the number of models Samsung puts out, now here's someone asking for more models.

I don't believe a thing what startups claim. All they have been doing is raising funds through misleading information.

woah, that means 3500mah could just be the size of a regular 2200mah battery.

I won't trust them until major OEMs can test them in the lab to make sure they don't blow up or anything
