Boeing Knew About the 787 Dreamliner’s Battery Problems Before It Caught Fire

The Boeing 787 Dreamliner was recently grounded across the world because its lithium ion batteries would self-combust in a blaze of glory (aka the batteries melt). What’s interesting is that Boeing knew about all the battery problems in the 787 before any flight was grounded. More »

Sony – “SX Series” (ICG-SX1000 & ICD-SX734) Voice recorder with high-quality sound and user-friendly functions

Sony’s new IC voice recorder is very practical and easy-to-use. Because of their new system called “3 microphone system”, you can select the most appropriate microphone mode according to the size of the venue or the recording object. If you think it’s difficult to adjust the setting by yourself, you can make the setting “Omakase Voice” (Automatic Voice Adjuster).
It has a large LCD screen and USB connection, so it makes data transfer very easy. The …

Toyota and BMW make it official, commit to green vehicle technology partnership

Toyota and BMW make it official, commit to green vehicle technology partnership

We’re well aware Toyota and BMW are pretty good pals, but details of their ongoing study sessions on green vehicle tech have been vague thus far. The trickle of information continues, and today the companies met to autograph more bits of paper and clasp hands for the camera. New binding agreements were signed to reaffirm deals inked in March and June last year, and their research into next-generation lithium-ion batteries has been expanded to cover the lithium-air kind (hopefully, they are less flammable). Work on making vehicles lighter continues, and they expect to complete development of an inclusive fuel cell system by the distant target of 2020. Expect to see some fruits of BMW and Toyota’s labor before then, though, as they intend to “define a joint platform concept for a mid-sized sports vehicle” by the end of the year. Don’t get too excited — we imagine that jargon means we’ll be privy to a few bits of artwork and some inspirational words come the deadline. If you’d like to know more about the evolving partnership, check out the source links below.

A123 Systems becomes America’s latest EV battery maker to file for bankruptcy

A123 Systems becomes America's latest EV battery maker to file for bankruptcy

Having been riddled with setbacks, including a major recall of faulty batteries supplied to Fisker Automotive, Michigan’s favorite EV battery maker A123 Systems has filed for bankruptcy. It has also announced the sale of its main business units to rival Johnson Controls in a deal pegged at $125 million — a sad fraction of the billion dollars it raised since it launched in 2001 (not least from government grants). It seems that neither fresh lithium ion innovations nor a potential deal with Chinese investors were able to keep the company out of the red, which leaves A123 on the road to nowhere — right behind that other DoE-sponsored hopeful, Ener1.

NC State nanoflowers can boost battery and solar cell capacity, make great prom accessories

NC State crafts nanoflowers that boost battery and solar cell capacity, would make great prom accessories

We see a lot of sleek-looking technology pass through our doors, but it’s rare that the inventions could be called beautiful by those who aren’t immersed in the gadget world. We’d venture that North Carolina State University might have crossed the divide by creating an energy storage technology that’s both practical and genuinely pretty. Its technology vaporizes germanium sulfide and cools it into 20-30 nanometer layers that, as they’re combined, turn into nanoflowers: elegant structures that might look like the carnation on a prom dress or tuxedo, but are really energy storage cells with much more capacity than traditional cells occupying the same area. The floral patterns could lead to longer-lived supercapacitors and lithium-ion batteries, and the germanium sulfide is both cheap and clean enough that it could lead to very efficient solar cells that are more environmentally responsible. As always, there’s no definite timetable for when (and if) NC State’s technology might be commercialized — so call someone’s bluff if they promise you a nanoflower bouquet.

Researchers create algorithms that help lithium-ion batteries charge two times faster

Researchers create algorithms that help lithium-ion batteries charge two times faster

Researchers at the University of California San Diego have devised new algorithms that can cut lithium-ion battery charge times in half, help cells run more efficiently and potentially cut production costs by 25 percent. Rather than tracking battery behavior and health with the traditional technique of monitoring current and voltage, the team’s mathematical models estimate where lithium ions are within cells for more precise data. With the added insight, the team can more accurately gauge battery longevity and control charging efficiency. The group was awarded $460,000 from the Department of Energy’s ARPA-E research arm to further develop the algorithm and accompanying tech with automotive firm Bosch and battery manufacturer Cobasys, which both received the remainder of a $9.6 million grant. Wondering if the solution will ever find its way out of the lab? According to co-lead researcher Scott Moura, it’ll see practical use: “This technology is going into products that people will actually use.”

Toyota plans dialed-back launch of eQ and iQ EV city cars in December

Toyota plans limited launch of eQ and iQ EV in December

Toyota’s just-arrived RAV4 EV will soon get a much smaller cousin — albeit a very elusive one. An electric version of the iQ city car will arrive in Japan (as the eQ) and the US (as the iQ EV) this December, but the automaker is significantly scaling back its 2010 promises of several thousand cars sold per year to just 100 fleet-oriented vehicles. The charging times, costs and range of EVs do not meet society’s needs,” vice chairman Takeshi Uchiyamada says to explain the smaller ambitions. It’s easy to understand the cautious approach after seeing the car’s final details. While they’re not out of line with the specs of other EVs, the eQ’s 3-hour fast charge, 62-mile range and ¥3.6 million ($46,130) price wouldn’t have regular customers flocking to dealerships. Most of Toyota’s energy is instead being funneled into its tried-and-true hybrids, with 21 due on the market by 2015, as well as plans to deliver the company’s first hydrogen fuel cell car by the same year. Eco-conscious drivers may be disappointed that Toyota isn’t moving as aggressively into a pure electric realm as some of its rivals, but we’d rather see smartly planned baby steps than an overly risky plunge.

Editorial: Physics and politics stand in the way of true mobile

Editorial Physics and politics stand in the way of true mobile

Progress is lumpy. The future is attained in a series of epochal strides, each followed by a lot of relatively inconsequential shuffling forward. The invention of the internet (and especially the consumer-friendly web) was a rare giant step that motivated immense adoption of computers and digital lifestyles. A global marketplace of online citizens spawned gadgets, software apps, corporate gold-rushing and other feverish shuffling.

Even with the opulent gadgetry we admire and enjoy, the whole expanding tech bubble seems to be reaching for something beyond itself. The incremental improvements of personal technology don’t thrust into the future as much as push against constraining walls of the present. Sharper screens and thinner computers are delightful results of corporate development cycles. But we are tethered to the present, which one day will seem primitive in retrospect, by two unglamorous bridles: power and connectivity.

LG Chem develops very flexible cable batteries, may leave mobile devices tied up in knots

LG Chem develops cableshaped flexible batteries, may leave mobile devices tied up in knots

The world is no stranger to flexible batteries, but they’ve almost always had to be made in thin sheets — that doesn’t amount to a long running time if you’re powering anything more than a watch. LG Chem has developed a flexible lithium-ion battery that’s not just better-suited to our bigger gadgets but could out-do previous bendable energy packs. Researchers found that coating copper wires with nickel-tin and coiling them briefly around a rod results in a hollow anode that behaves like a very strong spring; mating that anode with a lithium-ion cell leads to a battery that works even when it’s twisted up in knots. Join multiple packs together, and devices could have lithium-ion batteries that fit many shapes without compromising on their maximum deliverable power. Some hurdles remain to creating a production-grade battery, such as a tendency for the pack to shed a small amount of capacity whenever it’s put under enough stress. LG Chem is fully set on turning these cable batteries into shippable technology, however, and could ultimately produce mobile devices and wearables that really do bend to their owners’ every whim.
