New Battery Tech Could Offer 3 Times More Power

Crushed silicon can create a smartphone battery that lasts three times longer than current cells

The mobile tech world has been growing at a ridiculous rate over the last few years.  Processor cores continue to multiply, screens get bigger and brighter, wireless speeds increase, cameras get faster and better, etc.

One thing that hasn’t really evolved with all these changes though is battery technology.  In fact, batteries are becoming a major downfall of many phones.  Lack of a removable battery can be a deal breaker for some.  Too small of a battery and the phone will likely not succeed.

Well it seems like a very promising new battery technology could be on the way.  An engineer, Sibani Lisa Biswal, and research scientist, Madhuri Thakur, from Rice University have discovered that crushed silicone can offer 3 times the battery capacity of your traditional lithium-ion battery.  Apparently, this crushed silicone can hold 1000mAh per gram versus the 350mAh per gram on the traditional battery.

If this technology comes to market it could be a major game changer.  Not only could you have longer lasting phones, but phones could get even thinner since a smaller battery could hold more charge.  This could potentially pair very well with something like a flexible screen display which would be aimed to be super thin.

I’m very much looking forward to seeing crushed silicone powered batteries in my future phones.

    Please never report on these – they’re always heartbreaking. By all accounts we should have been using Li-Air batteries 5 years ago (HP tried but stopped for some reason), or LiIon batteries with carbon nanotube anodes, or an array of brilliant laboratory discoveries that all seem to be silenced and suck our hopes away. The only thing that will increase your batter life in the next few years: more efficient radios (less packet loss), more efficient screens (backlights, or lack thereof in OLED), and bigger batteries. Sad but true

    I understand the need and want for smaller and better batteries, HOWEVER, I’d take a thicker phone with a bigger battery any day over a thin phone that has a cruddy battery. My GNex has decent battery life, but I can only imagine how much better it would be if they made the phone slightly thicker with a bigger battery (yes, I know you can get a bigger batter for it, and I did). I ended up buying a case for my phone not because I wanted to protect, but to make it thicker and easier to hold.

    Yeah I think it’s far too early to be reporting stuff like this – the tech market is filled with the broken promises of researchers fishing for investment money. I personally think battery tech is the absolutely number one restriction in the mobile computing market, though. Geeks get all worked up about screen densities,compute speeds and physical profiles of devices, but these are all issues that are giving consistently smaller returns on investment every year. You’re only going to be so thin, pretty soon any thinner and the device will become awkward. Speeds and screen displays will continue to get better and cheaper, but not enough to make you fall off your chair. Powering these devices, however, is woefully behind. Can you imagine a modern phone or tablet that could match, say, the battery cycles of a Kindle? That’s the target, that’s why the Chinese government has dumped millions into battery research, that’s why stories like this are everywhere. Whoever owns a cheap, practical, long lasting mobile power source tech will become incredibly powerful over the next 20 years.
