U.S. battery materials supplier, 3M, has recently been granted $4.6 million by the U.S. Department of Energy to further their efforts in creating the next advancement for lithium ion batteries. There's hope that a major change in lithium ion batteries will positively affect their use in electric vehicles.
Currently, 3M is doing research around their latest patent, which involves Silicon anodes that could increase call capacity by over 40% when matched with certain cathodes.. This, of course, could have an effect on not just larger-scale lithium ion batteries, such as for electric vehicles, but even smaller-scale lithium ion batteries used in cell phones, laptops, and camcorders.

New iPad owners, beware: there's been a lot of talk revolving around whether iPads are now "too hot". Forums have been abuzz with Apple customers repeating this complaint, but the question remains: does it get dangerously hot?
According to tests run by Consumer Reports, "The New iPad gets up to 13 degrees hotter than the iPad 2 when playing a game." This was tested by running the famous iPad game Infinity Blade II for 45 minutes while propped up and charging. Overall, the New iPad hit a high of 116 degrees Fahrenheit!
Previous tests and reports by Consumer Reports also concluded that laptops/netbooks could reach up to 120 degrees, at which point it may begin to damage bare skin over time. However, that doesn't seem to be a major point of worry, as most users also note that the iPad only gets "overly warm".
Apple's PR Truly Muller commented to AllThingsD, "The new iPad delivers a stunning Retina display, A5X chip, support for 4G LTE plus 10 hours of battery life, all while operating well within our thermal specifications. If customers have any concerns they should contact AppleCare." Whether this turns out to be as bad as the iPhone 4's AntennaGate scandal remains to be seen.

The latest iteration of Apple's tablet, the New iPad, is just as good at staying alive as its predecessors. Ever wonder how it manages to stay on for so long though? Especially in today's age, when battery-life is definitely a major factor in people's choices for laptops, smartphones, and other accessories.
Turns out, the New iPad has a whopping 42.5Whr battery. Quick flashback: the original 1st-generation iPad had a 24.8Whr battery, while the iPad 2 had a 25Whr battery. And while the New iPad is only 0.6mm thicker than the iPad 2, one just has to wonder: how in the world did Apple do that? According to arstechnica's teardown (note: Consumers should not try this at home), Apple simply managed to "more efficiently pack in the components - and increase the overall device thickness ever so slightly". No magic here, folks.
No matter how much you want to stare at the battery out of curiosity, tearing the device apart is always dangerous and likely shouldn't be done. And as fun as it is, professionally taking it apart is definitely still a better option than dropping it - which is proven to be fatalfor the iPad, if squaretrade's blog and video is any indication.

NEC's unveiled their newest prototype of their Ultra-thin organic radical battery (ORB) today, measuring in at 0.3 mm. These batteries are not only small, but also flexible, and can be attached to integrated circuit (IC) cards. The IC cards themselves aren't too think either (measuring around 0.73 to 0.76mm thickness on average).
The power behind NEC's latest ORB is enough to match a Li-Ion battery. That's not to say that it'll run your laptop, but ratio-wise, it delivers a higher power output and faster recharging speeds. Currently, these new batteries have a capacity of 3mAh, which should be enough to perform 2,000 display screen updates, 360 consecutive flash firings and 35 location transmissions on just one charge. As far as longevity, these ORB's retain 75% of their charge/discharge capacity even after 500 cycles, similar to the performance of Li-Ion smartphone batteries.

Although there was no Apple iPad 3 at CES on display, there has been a rumor going around that the Apple iPad 3 might be launched in a few months, March of 2012. The new iPad 3 also might be very similar to the iPad 2, but with improved hardware overall. Apple already knows the next iPad 3 is going to be a success, just like it’s iPad and iPad 2 predecessors. It’s no surprise that there won’t be any sneak peeks before it is released.
Below are some rumored Apple iPad 3 specs:
• An improved Apple A5 dual-core 1GHz processor or a possible A6 quad-core processor.
• Retina Display, 9.7-inch QXGA 2048 x 1536p resolution HD display.
• Super-sharp display with 326 ppi (pixels per inch) or greater. iPad 2 is 132 ppi.
• 4G LTE radio for faster internet speeds.
• Larger 14,000mAh battery for the iPad 3. The iPad 2 battery is rated at 6930 mAh.
• 10 hours of video watching over Wi-Fi.
• Improved HD Facetime front camera and 8 megapixel or higher rear camera, like the iPhone 4S.
• Storage options could range from 16 GB, 32 GB, 64 GB, and a possible 128 GB with iCloud services.
• Thicker casing.
• Stronger glass comparable to Gorilla Glass 2.
• AT&T and Verizon carriers.
• Addition of Siri.
Although these are just rumores on iPad 3 specifications. We can expect an iPad 3 arrival sometime in March 2012, and a possible iPhone 5 in the pipeline. The iPad 3 specs sound good and we will all wait impatiently for the next release.
