Can you imagine a battery that is 1 billionth of a meter thick and as tall as the thickness of a human hair? Scientists at Rice University have developed a new tiny, tiny lithium ion battery. It is only 150 nanometers thick (1 billion nanometers to equal 1 meter). It is so small that it is hard to see with the naked eye.
The idea here is to fabricate nanowire energy storage devices with ultrathin separation between the electrodes, said Arava Leela Mohana Reddy, a research scientist at Rice and co-author of the paper. This affects the electrochemical behavior of the device. Our devices could be a very useful tool to probe nanoscale phenomenon.
So far battery technology hasn't been able to power our electronic devices for more than 10 hours at a time. Even with the largest capacity lithium ion batteries, Smartphones act like battery vampires sucking the charge right down. The largest capacity cell phone battery I have seen is 4000mAh. The problem is that these extended capacity batteries are heavy and much thicker than the standard batteries that come with the phones. This means that you need an extended battery cover as well as the fact that the gel case you bought to go with your new Smartphone will no longer fit. The new nano batteries would mean you could get huge capacities in tiny batteries, thus making the Smartphones lighter and thinner.
Will we be seeing this new technology any time soon? It's probably a few years down the road, but just think of how light weight those new MacBook Airs will be in the future Will your new Smartphone be as thin as a credit card? The possibilities are endless.
Meanwhile, back at the farm While we wait for the new nano technology to catch up to our needs, you will need another solution. I have a Motorola Droid X. The battery life for the standard battery was dismal to say the least. I love the phone, but let's face it, having to be tied to a charger by mid-day was painful, as well as inconvenient. I bought a Droid X extended battery and am so much happier. My new battery is 2600mAh, which gives me almost twice the capacity as the original 1390mAh battery that came with the phone. I have heard that there is a new aftermarket battery for the HTC EVO 3D. The new HTC EVO 3D extended battery is 4000mAh. Amazing! Of course it will be much heavier than the standard 1700mAh battery that comes with the EVO 3D, but as with all 4G Smartphones, you need that extended capacity to make it through the day. Let's hope that the nano batteries will be here sooner rather than later.
