Flexible batteries get the graphene treatment, could be cheaper than other bendy batts
We've been talking about flexible batteries for years now, but a team of Korean researchers have presented a new solution to bendable energy sources that is not only more powerful than standard lithium-ion batteries, but also potentially cheaper to produce than its malleable predecessors -- and unsurprisingly, everyone's favorite wonder material, graphene, is at the heart of the innovation. The rechargeable battery contains a vanadium-oxide cathode, grown on a sheet of graphene paper, an unidentified separator, and an anode made of lithium-coated graphene. According to the folks behind the new power source, it sports higher energy and power density, as well as a better cycle life than the literally stiff competition. Similar advances have also out-performed rigid lithium-ion batteries, but have enlisted carbon nanotubes, a material more expensive to produce than graphene. Of course, like all technological advances, we won't be seeing these things for years, if not decades, so you might as well get used to ye olde standard bearer.
Stanford develops safer lithium-sulfur batteries with four times the charge of lithium-ion cells
Longer battery life is high atop our list of gadget prayers, and the brainiacs at Stanford are one step closer to making our dreams come true with a new lithium-sulfur technology. Half of this trick lies in the silicon nanowire anode that the same team developed back in 2007, whereas the new cathode consists of a similarly commodious lithium sulfide nanostructure. Compared to present lithium-ion batteries, Stanford's design is "significantly safer" and currently achieves 80 percent more capacity, but it's nowhere near commercial launch with just 40 to 50 charge cycles (Li-ion does "300 to 500") due to the compound's rapid degradation. That said, we're promised a theoretical quadruple boost in capacity as the technology matures, so until then we'll keep that hamster running in our backpack.
South Korean researchers devise a safer lithium ion battery
While some researchers are focused on making batteries that are both safer and longer-lasting, it seems like the folks at the Korea Atomic Energy Research Institute (or KAERI) are simply concerned with making 'em really, really safe. To that end, they've now announced that they've managed to develop a new type of "separator" that is said to be far more resistant to heat and impact than traditional polyethylene separators. Made from a mix of polyethylene, nano-alumina and flourine-based resin that has been subjected to radiation, the new separator can supposedly hold up to temperatures of 150 degrees Celsius and "considerable outside impact," and it can apparently be applied to all sorts of lithium-ion batteries -- including everything from phones to laptops to electric cars. Of course, there's no word as to when we might actually see the new and improved batteries, but KAERI has apparently already applied for the necessary patents for the new technique.
Korean geniuses invent lithium batteries with eight times the juice
Oh, what wondrous things come from the land of Korea -- dancing emotional robot humanoids, oxygen-emitting robot plants, and multiple 24-hour StarCraft channels. It's all good, and we dig robotics and televised gaming, but this latest invention could be our favorite if it pans out. Professor Cho Jae-Phil and his team at Hanyang University have replaced the graphite in lithium batteries with a certain kind of silicon, which we're told can store eight times the power. No word on what the batteries have actually been used for yet, but it stands to reason they could eventually make it to consumer electronics. Now you see why we're willing to say this might be better than 24-hour StarCraft. Say it with us: 48-hour StarCraft.
Lithium Remote Server Monitoring Eye Candy
I first heard about the Lithium network monitoring application a while back in an article on Macworld describing how beautiful it was, but I just found out today that Lithium offers a FREE Edition (for a limited time) that anybody can download and use to monitor up to 10 devices. Lithium comes in two parts: Core that runs on your OS X (or Linux) sever(s) and a Console program that runs on your Mac, which allows you access to the data generated by the Core (you can also access the data on the web or with a Windows client). If you have a multi-mac home network or perhaps a Mac co-lo this could be a very attractive way to keep tabs on your server(s).If you have more than 10 devices you can upgrade to the Professional (25 devices) or Enterprise Edition (Unlimited devices) for $198 or $839 respectively. Who knew server monitoring could look so good?[Via FreeMacWare]
Air Oxyride: 100 batteries included
Panasonic has bumped up the power of its Oxyride batteries, claiming the new version is 120% more efficient than the original model. And to prove it, Panny has decided to launch an airplane powered by 100 AA Oxyride batteries (you might recall that the original Oxyride was heralded by a battery-powered ultralight vehicle). No word on how far the plane will be able to go powered on those AAs -- or whether Panny's actually managed to recruit anyone to fly the thing (though we hear Richard Branson is game). We assume that, after this stunt, Panny will roll out next year's upgrade with an Oxyride-powered space shuttle, and follow that one with a battery-powered lunar colony. Maybe after that, they'll consider something really dramatic, like beating disposable lithiums or rechargeable NiMHs in a digicam.
