Device warns of catastrophic failure in lithium-ion batteries, robots celebrate
"Catastrophic lithium-ion battery failure" are five words Malfunctioning Eddie never wants to hear, and may not have to, thanks to a new sensor developed by the folks at the Johns Hopkins University Applied Physics Laboratory. Despite the popularity of lithium-ion batteries in everything from consumer electronics to hybrid and electric vehicles, they have been associated with a phenomenon called "thermal runaway" -- known to cause overheating and potentially, fire. The newly developed device measures the electrical parameter of the cell, which is an indicator of whether the internal layer temperatures are getting too toasty. The best part? The warning comes before the heat can reach the surface and cause catastrophic failure, perhaps saving our electronics from a fate like the one in the video after the break.
Has James Bond gone green? Bulletproof electric roadster in the works
Warding off assassins while saving the environment just became a cake walk with the Jo-Mojo, an upcoming creation by Lativian armored vehicle company DARTZ. This two seat convertible roadster brandishes an 80 horsepower electric engine capable of pushing zero to 60 mph in 9.5 seconds and a top speed of 125 mph -- yet most of its "mojo" is outside the hood. Custom seating, color-changing chameleon paint finish, bulletproof tires, and others are just a few of the many "drooling" features. The sunroof is given a task with flexible solar panels built-in, good for juicing up the batteries while idle or on the go. Aimed to hit the market at the end of Q2 2012, its estimated price tag starts at 30,000 euros (~ $40,000), within range of most low-end luxury automobiles. Check past the break for a video slideshow of this snazzy piece of metal by Gray Designs, DARTZ's partner in the venture.
Captain's Log: To spec or not to spec?
Captain's Log, Stardate 65340.3... Hello, computer (and players)! Unlike an answer to Shakespeare's original question, the answer to the question in this week's title is probably a no-brainer for most of you: Yes! Choosing a specialization, or "speccing," in MMOs is something that stretches across most titles out there, and Star Trek Online is no different. Whether you wish to resist attacks longer, do more damage, or add strength to your powers, choosing a customized spec can be rewarding and a challenge at the same time. With so many variables and places to spend your points, the possibilities are endless. While this week's Captain's Log is not here to tell you what you should spec into for your particular class or ship set-up, I would like to go over the space skill point overhaul that STO is about to go through. In the past, one of the biggest complaints from players was that they did not have a clear understanding of which skill tree affected which ability. The devs heard this feedback and have been working on a complete revamp to make these decisions simpler. Hopefully, this will allow you to have a better understanding of where and why to spend your points in a particular skill when you do have to re-spec at the launch of F2P on January 17th, 2012. Ensign, warp 10! Let's get our readers' bookmark buttons ready...
Dipping capacitors and batteries in nanotubes could improve capacity
Stanford researchers figured out that, by dipping electrodes for super capacitors in a solution of carbon nanotubes or a conductive polymer they could increase the charging capacity by up to 45-percent. The team started working with composite electrodes of graphene and manganese oxide, since manganese is cheap and plentiful, but were hamstrung by its low conductivity. The thin coating of more conductive material greatly boosted the capacitance of the electrodes, and thus their ability to hold a charge. Further tests are still required to find the actual energy density of the dipped electrodes, but lead researchers Yi Cui and Zhenan Bao are already working on a way to apply the same technique to batteries.
Evolta robot to take on the Ironman Triathlon, conquer the course in a week
Panasonic's little battery-powered bot that could, the Evolta, has garnered our attention several times over the years. It's already climbed out of the Grand Canyon and walked 500km from Tokyo to Kyoto, but apparently neither was enough to prove it and its namesake batteries' true mettle. This time, Panasonic's putting three of the robots through the Ironman Triathlon in Hawaii, and they've got a week to swim 2.4 miles, bike 112, and run a 26.2 mile marathon. Unlike the meatbags running the race who have a day to finish, the robots get a week -- though they'll be doing their thing 24 hours a day while only taking breaks to recharge their three AA batteries. Intrigued? The race starts on October 23rd, so there's plenty of time to watch the appropriately dramatic video explaining the challenge facing the triumvirate of tiny triathletes after the break.
New 'subconscious mode' could improve smartphone battery life, supress your WiFi id
Researchers at the University of Michigan have figured out a way to drastically increase your cellphone's battery life, at least while using WiFi. By using what they're calling E-MiLi, or Energy-Minimizing Idle Listening, professor Kang Shin (right) and student Xinyu Zhang have developed a proof of concept that could extend battery life up to 54-percent with the WiFi radio on. Even when idle, a wireless radio is actively checking for incoming traffic. E-MiLi scales back the wireless card's clock to just 1/16th of its normal operating speed, and only kicks back into full gear when it senses incoming data. To be really useful though, we'd love to see the same trick employed on cellular data networks -- that LTE sure is fast, but it's not exactly battery-friendly. Check out the PR after the break.
Leeds researchers tout gel-based batteries as better, safer and cheaper
They're some fairly bold claims, but a team of researchers at the University of Leeds say they've managed to develop a new type of polymer gel that could lead to batteries that are safer, cheaper to manufacture and more flexible than traditional lithium-ion batteries. That last detail could have some particularly interesting consequences, as the researchers say it allows for batteries that can "shaped and bent to fit the geometries of virtually any device." What's more, all of that apparently comes with no compromise in performance, and the team has already licensed the technology to Polystor Energy Corporation, which is now conducting trials to commercialize the battery cells. The only catch is that there's not so much as a hint as to when such batteries might actually be available.
Nichicon lays claim to the world's smallest EV chargers with NGQ-202, NGQ-203 models
Although it'll still be hard to misplace in your pile of electronics, a company called Nichicon has launched what it says is the world's smallest chargers for electric vehicles, the NGQ-A202 and the NGQ-A302. By using what the company calls advanced module technology, it was able to shrink its EV charger down by 50 percent to around 59 x 13.8 x 23.6 inches, also reducing the weight by up to 66 percent. Compatible with the ChAdeMO standard, these 20-30kW chargers will work with electric vehicles like Mitsubishi's i-MiEV and the Nissan Leaf, taking between 35 and 60 minutes to fully power your whip. Charging doesn't come cheap, however, as the batteries are said to retail between $24,600 and $27,000 when they launch sometime in October. Next step -- cutting the cord and going wireless, perhaps?

Researchers use graphene and tin sandwich to make better battery electrodes
Graphene, that microscopic chicken wire made of carbon atoms, has a great many theoretical uses. Among these is to improve Lithium-ion battery technologies, and the big brains at the Lawrence Berkeley National Laboratory have created a graphene and tin composite material for use in battery electrodes. When it's baked at 572 degrees Fahrenheit (300 degrees Celsius) the tin turns into nanopillars that widen the gap between the graphene layers. The greater volume of tin provided by these tiny towers improves electrode performance (read: faster charging), and the flexibility of the graphene prevents electrode degradation. Naturally, current prototypes can only maintain capacity over 30 charge cycles -- as opposed to the hundreds required for commercial applications -- so some serious improvement has to happen before we see it strut its stuff in any phones or EVs. This leaves us, once again, extolling the virtues of graphene, but lamenting its exclusively academic application.
Stanford researchers create transparent battery, dream of a see-through iPhone (video)
We've had about all of the transparent displays we can handle. Besides, what good is a screen you can see through if the electronics behind it are as opaque as ever? Thankfully, the fine folks at Stanford are working hard to move us towards a future filled with invisible gadgets. Yi Cui and Yuan Yang led a team that have created a lithium-ion battery that appears transparent. In actuality, the cells are composed of a very fine mesh of electrodes, approximately 35-microns wide, that are small enough to appear invisible to the naked eye. The resulting power packs are cheap and flexible but, currently, can only store about half as much energy as a traditional Li-ion battery. Cui has a particular destination in mind for creation, as he told the college paper, "I want to talk to Steve Jobs about this. I want a transparent iPhone!" Check out the video after the break.
Sony eyes electric car future, wants to soon sell you Li-ion batteries
Sony must be smelling dolla dolla bills in the EV-charged streets because the company just announced its intentions to fab lithium-ion batteries for the cars mid-decade. The statement, made from its plant in Motomiya, hinges on a future market flush with consumer demand for the earth-friendly autos, and could see the construction of several dedicated factories. Given the Japanese company's recent history eating bits of competitor dust (hello Wii and iPod), we understand its forward-facing desire to become king of this Li-ion hill. But the mega-electronics maker isn't placing all of its batteries in one fuel-source just yet -- it's "also [considering] developing batteries for gasoline-electric vehicles and plug-in hybrids" -- should they win the green energy popularity contest. While we applaud the company for encouraging adoption of the environmentally-friendlier tech, we'd much rather see them make batteries for this bad boy from tomorrowland.
Denmark lands Europe's first Better Place EV battery swapping station
Better Place continued on its quest of global EV-battery-switching domination, Tuesday, bringing its special drop-and-swap charging solution to the fine folks of Gladsaxe, Denmark. An automated robot arm ceremoniously traded out the battery in a Renault Fluence Z.E., marking the beginning of a nine-month roll out across the country. The aptly titled Battery Switch station is the first of its kind in Europe and the first of 20 to be installed in Denmark. It was a monumental occasion, to be sure, one that could have only benefited from a performance of Michael Jackson's Heal the World as sung by Danish humanoid (and ladies' man) Geminoid-DK.

SEI creates new porous Aluminum-Celmet, makes rechargeable batteries last longer
Quick: What costs hundreds of dollars and dies after four hours? If your answer included anything portable and tech-based -- you guessed right. In fact, most of our magical and exciting gadgetry has less-than-stellar means of holding a charge, but a recent breakthrough by Sumitomo Electric Industries could change all that. Employing the same process used to create Celmet (a NiMH component), researchers at the R&D company managed to coax aluminum into being a bit more receptive. The resulting Aluminum-Celmet has a whopping 98 percent porosity rate, leaving the Li-ion gate wide-open for a flood of electrical juice. And unlike its nickel-based brother, this piece de porous non-resistance has a steep corrosive threshold that could soon help power a line of high-capacity, small form rechargeable batteries. Production is already underway at Osaka Works, with SEI hoping to speed adoption of these franken-batts into our mass consuming mitts. Technical-jargony PR release after the break.
Toshiba SCiB to be used in Mitsubishi i-MiEV, recharge to 80 percent in just 15 minutes
Toshiba's SCiB (Super Charge Ion Battery) technology has long been the source of great hope and anticipation in electronics circles, but it's never quite delivered the world-changing retail products that its marketing promised. Hoping to correct that in a big way, the company's now hooked up with Mitsubishi to distribute said fast-charging cells in the taxman-friendly i-MiEV (to be known as Mitsubishi i in the US) and its taxi variant, the MINICAB-MiEV. How fast-charging, you ask? We're told recharging will be done in 15 minutes for 80 percent, 10 minutes for 50 percent, and a mere 300 seconds for 25 percent. You'll need a CHAdeMO charger to achieve such rapid revitalization rates, but those stations are sprouting up across the US now. There are other favorable qualities to Toshiba's batteries, including "excellent charging and output" under very low temperatures, 2.5 times the number of charge / discharge cycles of regular lithium ion cells, and safer operation than most other alternatives.

Bird Electron EP-15V charges your MacBook Air from eight C-type batteries
Remember those thick C-type batteries you used to toss in your flashlights before the age of LEDs? Well, they're not likely to overtake the disposable battery market anytime soon, but they did just become slightly more useful to a very select number of Japanese MacBook Air owners. The EP-15V from Bird Electron will bridge eight of those C batts to create a 12-volt power source, giving your 11.6-inch MacBook Air a two-hour boost when used with standard alkaline batteries. The charger was released today in Japan, and will initially sell for ¥19,800 (about $250), not including batteries or the requisite MagSafe Airline Adapter (¥5,800, or about $75 in Japan). The EP-15V isn't likely to be the most practical option, considering its cost, size, weight (2.3 pounds, or just over 1 kilogram -- before you add batts), and the fact that you'll need access to an adapter and eight batteries, which you'll be tossing after just two hours of use. But if you find yourself in a remote village with a hearty C-type battery supply and no electricity or access to the sun, then you might just regret not picking one up.
Sanyo expands Eneloop battery offerings with Pro for more power, Plus for less heat
If you love Sanyo's ever-so-practical Eneloop rechargeable batteries, you'll be smitten with its two latest AA additions. First into the battery compartment is the 2400mAh Eneloop Pro; it's loaded with twenty-five percent more juice than the standard model, and is a perfect match for your power-draining Nikon Speedlight -- not quite as formidable as the 2,500mAh XX series, though. Moving onto the next slot is the Eneloop Plus, which adds a positive temperature coefficient thermistor -- a resistor that prevents the batts from reaching skin-scorching heat levels in kids' toys. Blazing Hello Kitty anyone? Both will come in packs of two or four, and also as bundles with a charger. Residents of Japan will be able to pick up the batteries at varying points this year, but aside from the ¥1,260 (about $15) Pro two-pack, pricing remains open. If your heart's beating like the pink bunny's drum, check out the source link below for the details and some fancy infographics.
New 'semi-solid' battery could recharge EVs as fast as pumping gas
Researchers at MIT reckon they've struck oil. In fact, you're looking at what they call "Cambridge crude" -- a substance that could halve the weight and cost of EV batteries and make them quicker to charge too. The black goo is packed with a high concentration of energy in the form of particles suspended in a liquid electrolyte. When separated by a filter, these particles function as mobile electrodes that can be pumped into and around a system before the energy is released. So instead of waiting up to 20 hours to juice your Nissan Leaf, you could potentially just pump this pre-charged substance into it -- rather like dirty old gas. Until now, no such "semi-solid flow cell" has been able to hold useful quantities of energy, but this stuff literally oozes with it. Not only could it power EVs, it could even be used for large-scale electricity storage for utilities. The researchers insist this energy revolution is years off -- but when it comes, there will be blood.
HP expands laptop battery recall, doesn't want you to feel the burn
HP wants to make sure you don't get burned, literally. For the third May in a row, it's issuing another expansion of its voluntary battery recall on laptops produced from July 2007 to May 2008 -- frankly, we're considering a holiday to mark the occasion. May 2009 saw a recall of 70,000 batteries followed by an expansion to cover 15,000 in China, totaling 85,000 affected laptops. It didn't end there though, as further expansion was put in place during May 2010 to cover even more models, and this time around, a sizeable number of lappies have been added to the ever-growing list. About five percent of the models from the aforementioned time frame could have problematic batteries, and HP will be providing replacements for those at risk of getting a little too hot under the collar. If your machine was also part of the previous recalls, HP's saying those should be verified as well, even if you've done so in the past already. The full grid of affected laptops can be perused after the break -- Memorial Day weekend will be full of grilling, but we wouldn't want that to include your skin, okay?
Third Rail zaps iPhone case market with detachable battery pack
For every gadget that claims to charge an iPhone on the go, there's sure to be a constituency that swears by it (or quite possibly at it). With external battery packs from HyperMac, Zagg, Kensington, Newer and Monoprice, you can dangle a cable; with battery-equipped cases from Exogear, Boost and Kensington you can keep your extra joules right next to your phone. We've seen some clever inventions (the RichardSolo 1800, the PowerEZ) and too-clever ones (the X-Power charger-in-a-cable), but precious few options that give you power when you need it without adding weight, aggravation and charging hassles. Since Macworld Expo this year, I've been happily using the US$79.99 mophie juice pack air with my iPhone 4 when I need extended power. It's light (about 68 grams), packs a solid 1500 mAh battery and charges reliably and simply with a Micro USB cable. It's a great product, but it does bulk up the phone substantially; if you carry the iPhone in a pocket, you'll notice the difference in weight and size (mophie's 2000 mAh product, the $99.95 juice pack plus, adds even more bulk and mass). I also don't need extra power most of the time; it's only when I've got a busy day on the road, and I can't charge here and there. If there were a way to get the all-in-one convenience of the juice pack without having to carry the battery all the time, I'd love it. That's why I was excited to check out Third Rail Mobility's new battery and case system for the iPhone 4, developed by a family of entrepreneurs who say they aren't afraid to touch the 'third rail' of mobile consumer electronics in addressing poor battery life. The system, on sale today, pairs a slimline 1250 mAh battery with a light protective case. But this battery comes off, attaching firmly when you need it and staying out of the way in your bag or jacket when you don't. I've been testing a prerelease unit for the past week, hoping to figure out if it truly is the best of both worlds. [Commenter beq points to a similar system from Tekkeon, which I had not heard of before; the $79.95 myPower case puts the battery into the top half of the case, allowing you to swap that out for additional charges. It does not include the stacking or third-party device charging features of the Third Rail system. –MR]
