Quantum batteries are theoretically awesome, practically non-existent

December 22, 2009

Today’s dose of overly ambitious tech research comes from the physics lab over at the University of Illinois at Urbana-Champaign, in a proposal titled “Digital quantum batteries: Energy and information storage in nano vacuum tube arrays.” It’s like a who’s who of undelivered promises got together and united to form one giant and impossible dream, but it’s one we’d prefer to believe in regardless. Aiming to improve battery performance by “orders of magnitude,” the project’s fundamental premise is that when capacitors — and we’re talking billions of them — are taken to a small enough scale and packed to within 10nm of one another, quantum effects act to prevent energy loss. The projected result is a wonderful world of rapid recharges and storage of up to ten times the energy current lithium-ion packs can hold, as well as the potential for data retention. The only problem? It would take a year just to build a prototype, meaning we can expect market availability somewhere between a score from now and just prior to the underworld morphing into an ice rink.

Stanford wants to roll its own paper batteries

December 9, 2009

It was only a couple of months ago that MIT was wooing us with the energy-preserving properties of carbon nanotubes, and in a classic act of oneupmanship Stanford has now come out and demonstrated paper batteries, which work thanks to a carbon nanotube and silver nanowire “ink.” We’ve seen this idea before, but the ability to just douse a sheet of paper in the proper magical goo and make a battery out of it is as new as it is mindblowing. Battery weight can, as a result, be reduced by 20 percent, and the fast energy discharge of this technology lends itself to utilization in electric vehicles. The video after the break should enlighten and thrill you in equal measures.

Energizer promises new and improved zinc-air battery for summer 2010

December 1, 2009

Energizer has been working on zinc-air batteries for quite some time now (along with plenty of others), but it looks like its now finally set to deliver with a new “standard battery” that’s said to be on track for a launch sometime in the summer of next year. What’s more, while some of the company’s previous attempts at zinc-air batteries have only been able to manage average run times of between one and three months, Energizer says it’s recently been able to triple things in time for the batteries’ big debut. That will first come in the form of some AAAA batteries from Energizer itself, which will apparently be priced similarly to “special lithium batteries,” and will eventually be followed by zinc-air batteries in a range of different sizes. During the same time, we should also start to see some of the first products with integrated zinc-air batteries from some of the 30 odd OEMs now working with Energizer, who are working to put the batteries into everything from Bluetooth headsets to remote controls to portable audio players.

South Korean researchers devise a safer lithium ion battery

November 17, 2009

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.

Fluidic Energy promises better, cheaper metal-air batteries, wins DoE grant

November 5, 2009

It’s not the only company working on metal-air batteries, but Scottsdale, Arizona-based Fluidic Energy may be in a better position to deliver on its promises than most, as it’s just managed to snag a $5.13 million research grant from the US Department of Energy to further develop the “breakthrough” technology. While that word’s thrown around quite a bit these, in the case, it may actually live up to the hype, considering that breakthrough in question would be a battery that’s able to deliver eleven times the energy density of the best lithium-ion batteries for less than one-third of the cost. The key to that, it seems, is the battery’s use of an ionic liquid as its electrolyte, which is described as a “wonder fluid” since it’s able to last significantly longer than other fluids because drying out isn’t a problem, and because it brings with it a significant boost in energy density. Of course, the company still apparently doesn’t have an actual battery to back up its claims just yet, and it’s not making any promises about when it might deliver one either.

Lenovo issues battery recall for six ThinkPad models

August 14, 2009

Lenovo’s issued a recall for the batteries on six of its ThinkPad models. The batteries are apparently causing a range of problems, including bringing up the error messages “irreparable damage” and “battery cannot be charged,” and causing overall short capacity batteries, or those than cannot be charged or experience massive drops on the fuel gauge quickly. The recalled models are the R60, R61, T60, T61, X60, and the X61, and Lenovo’s got a free diagnostic tool on its website that you can use to check and see if your model is one of those affected. While there’s no word on how many users have been affected, If you are one of the unlucky, the company is offering free replacements.

New Sony lithium ion batteries promise 4x the capacity, 99% recharge in 30 minutes

August 11, 2009

Sony’s certainly had its share of battery problems but, like most battery-makers, it’s also doing its part to try to improve things, and it’s now announced a new lithium-ion battery that should not only be more stable, but last significantly longer than traditional batteries as well. That’s apparently possible in part due to its use of an olivine-type lithium iron phosphate for the cathode material, which should help boost the battery’s overall lifespan to four times that of conventional lithium ion batteries, not to mention provide an 80% capacity retention after 2,000 charge-discharge cycles and, perhaps most impressively, a promised 99% recharge in just 30 minutes. According to Sony, the batteries are especially well suited for use in power tools (where they’ll first show up), but it does say they’ll also eventually be “expanded to a wide range of other mobile electronic devices.”

Eberhard’s RFMC rapid charger for Tesla Roadster now up for order

August 6, 2009

If you’re one of the lucky few who own a Tesla Roadster, this will certainly be of interest to you. And, for the rest of us — well, let’s indulge ourselves in a bit of vicarious living for a moment, shall we? Eberhard’s just made its rapid charger — the Roadster Foundry Mobile Connector (or RFMC) — available to order. The RFMC comes with adapters that will allow charging at 12, 16, 24, 32 or 40 amps, and a fully depleted battery will charge overnight when charging at 40 amps. All you need to do (owning a Roadster is the hardest part, no doubt) to get the newer, faster charger is send the standard MC120 charger the car came with, plus $960 to EV components, wait for the new RFMC to show up, then go back to your normal life — you know, sitting on a desolate beach in your insane car watching the sun go down.

Vice President Biden announces $2.4 billion in battery-related grants

August 5, 2009

It hasn’t been much of a secret that the US government was planning to dole out a couple of billion in battery-related grants to automakers this week, but we only got the details on who gets what today when Vice President Joe Biden made the big announcement himself in Detroit. As you might expect, the big three automakers all got a sizable chunk of the $2.4 billion up for grabs, with GM snagging $240 million for three separate grants, Ford getting $92.7 million (part of which will fund an electric-drive-parts facility in Michigan), and Chrysler receiving $70 million to develop and deploy advanced plug-in hybrid pickups and minivans. The single biggest winner, however, is Johnson Controls Inc., which got close to $300 million to produce battery parts for hybrid and electric vehicles. Chrysler partner A123 Systems Inc. was the next highest with $249.1 million, while EnerDel got $118.5 million that it’ll use for its Indianapolis plant that produces lithium-ion cells and battery packs.

Tiny, printable batteries promise to change the face of obnoxious greeting cards forever

July 2, 2009

Researchers at the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Chemnitz led by Prof. Dr. Reinhard Baumann have unveiled tiny, printable batteries that they hope to put into production for pennies apiece. The new battery prototype is primarily composed of a zinc anode and a manganese cathode that can be screen printed and covered with a non-printed template cover. Each mercury-free battery weighs less than one gram, and can individually produce about 1.5 volts of electricity. By placing several batteries side by side, however, up to 6 volts can be generated. The institute has already produced these little power houses in the lab, and hopes to see them into production by the end of the year. The batteries have a relatively short lifespan, making them suitable for applications such as powering greeting cards. All we can say is that this battery would have made the card we got two years ago that sang “Word Up” much, much awesomer.
