    How is Elon Musk going to produce his vaunted $35,000 Tesla when EV batteries are so expensive? By making his own. Tesla has signed a deal with Panasonic that'll see the pair team up to build the Gigafactory. It's from here that vehicle packs and cells will be mass-produced on an unprecedented scale that costs are expected to tumble. According to the announcement, Tesla will build the plant and maintain it, while Panasonic supplies the lithium cells, plant, machinery and manufacturing equipment to make the whole thing happen. The Gigafactory is expected to produce 35GWh of cells and 50GWh of power packs by 2020 and will be built just as soon as Musk and co. work out which state -- Arizona, New Mexico, Nevada or Texas -- depending on which has the better tax rebate renewable energy resources.

    If you're considering an iPhone case that includes a battery pack, you've already decided that increasing the size of your device is a fair trade-off for more life, but that doesn't mean that all battery cases are created equal. The iBattz Mojo Refuel I reviewed previously increased the overall footprint of the device quite a bit, and while the myCharge Freedom 2000 also creates an overall more bulky handset, it's not quite as dramatic as some of its competitors. Specs Capacity: 2000mAh Price: US$79.99 Design Like many of the battery pack cases, the myCharge Freedom 2000 slaps the majority of its weight onto the rear of the device. The iPhone clicks into place easily and the case keeps a relatively firm grip on your phone. There are cutouts for the camera, volume buttons, and silent switch, and a built-in lock button that, in theory, carries your button push through to the device below. Unfortunately, the button is flush with the case and can be a bit of a challenge to push. This is the one big issue I have with the case in terms of design, but it's not a deal breaker. The sides of the case are a semi-flexible hard plastic, while the rear of the case has either a matte feel or a slightly textured, glossy paint, if you choose one of the more colorful case options. The fit and finish of the case itself is very high, and it doesn't have the cheap toy feel that some cases fall victim to. The most unique aspect of the Freedom 2000 case is that it has an open-bottom design, exposing the entirety of the device's bottom ports and speakers. This is great for people who want to recharge just the phone and not the case, and even allows the use of some docks without removing the case. On the bottom of the case there is a small built-in cord that plugs into the iPhone's Lightning port to allow the extra battery to recharge the device. There's also a MicroUSB port on the bottom of the case to recharge the case itself. Functionality This case works slightly different than most; Rather than being permanently plugged into the iPhone's charging port, the Freedom 2000 requires you to plug the case into your phone whenever you need a little extra juice. Once you've connect the case to the phone, you initiate the charge by pressing and holding the battery button on the back of the case. A quick tap of the battery button reveals how much charge you have left in reserve. Conclusion As far as iPhone charging cases go, the myCharge Freedom 2000 is one of the more unique options. The open-bottom design is great for users of docks and those who want to still get some use out of their lightning cables, and the exposed speakers means no muffled music or game sounds. The lock button is my single sticking point, but it's a small price to pay for having what is essentially a full battery recharge available any time you need it.

    Nikon released a firmware update for its D3100, D3200, D5100, D5200 and Coolpix P7700 cameras during November, which only seemed to change how battery life was measured for a specific pack (the EN-EL14a, if you were wondering). Well, that's what the patch notes would have us believe, anyway, but according to some owners who've updated, the new version also stops those cameras working with third-party batteries. This isn't the first time a camera maker has used code to block unofficial power packs, and it'll no doubt irritate those who've passed on Nikon's $41 (EN-EL14) or $60 (EN-EL14a) spares in favor of cheaper options missing a logo. There doesn't appear to be any way to roll back the firmware version, so if you hadn't gotten round to updating yet, you might want to reconsider. We've reached out to Nikon for comment, and if we find out exactly what's buried within the unassuming update, we'll fill you in right here.

  • Researchers create self-healing batteries inspired by artificial robot skin

    In the race to create a better battery, scientists have gazed longingly at silicon, prized for its ability to hold copious energy during charging. The material has a significant drawback, however: it likes to expand during said charging, causing it to eventually crack and become useless. However, scientists at Stanford's SLAC laboratory have developed silicon electrodes that repair themselves, inspired by -- of all things -- the latest research into robotic skin. They created a silicon polymer with weak chemical bonds which attract each other when the material cracks, allowing it to regain its shape in a few hours (as pictured above). The team managed a respectable 100 discharge cycles with a battery that used the material, a promising start but still far from their goal of 3,000 cycles for an electric vehicle. You can add that to the growing pile of promising battery tech that may amount to something, some day -- but at least the odds keep getting better.

  • Apple patents flexible batteries that would fit nicely in an iWatch

    For sure, Apple patents a lot of innovative technology that never sees the light of day. However, sometimes certain patents stand out due to current technology trends and stronger signs that Apple may indeed be working on a new iDevice. One such example that fits that description is a patent for an Apple invention that allows for flexible battery packs. The patent was published by the US Patent & Trademark Office yesterday and discovered by Patently Apple. As PA notes: Apple's invention relates to flexible battery packs for use in electronic devices that overcome one or more of the drawbacks of conventional battery packs. In one embodiment of the present disclosure, the flexible battery pack may include a plurality of cells, such as galvanic or photovoltaic cells. The battery pack also may include a plurality of laminate layers coupled to the cells that include a top laminate layer and a bottom laminate layer. An adhesive may be used to couple the top and bottom laminate layers together such that each of the plurality of cells is isolated from each other. This arrangement may allow the battery to be shaped to fit a form factor of the electronic device. This arrangement also may allow one or more of the cells to be selectively removed from the plurality, which may be desirable from a manufacturing perspective. One drawback of a smart watch is the amount of battery it would need to last all day, or indeed, all week. When people imagine the iWatch, it is often assumed the battery would sit behind the face plate. However, if Apple has come up with a way to make thin, curved batteries, the entire wriststrap could be a battery, thus enabling longer usage between charges. Does this patent signal that an iWatch is coming? Not totally, but combined with the recent iWatch trademark filings, it is evident that technology from this patent could be used in such a device.

    We often hear about the coming nanobot revolution, but just how are scientists planning on powering these future marvels? Well, researchers from Harvard and the University of Illinois may have found the solution in a 3D-printed battery: it's smaller than a grain of sand, yet has areal energy and power densities comparable to your cellphone battery. The team used a custom 3D printer with a 1mm wide nozzle to deposit two separate lithium metal oxide pastes into comb-like shapes, which then hardened to create an anode and cathode. After adding an electrolyte, a sub-hair-width cell was created with "performance comparable to commercial batteries in terms of charge and discharge rate, cycle life and energy densities." Those could someday wind up in medical devices, wearable electronics or tiny flying drones, for instance. To see how they did it, check the video after the break.

    Supercapacitors are often hailed as the holy grail of power supplies, but a group of researchers at the University of Illinois have developed a lithium-ion microbattery that leaves that prized solution in the dust, recharging 1,000 times faster than competing tech. Previous work done by Professor William P. King, who led the current effort, resulted in a fast-charging cathode with a 3D microstructure, and now the team has achieved a breakthrough by pairing it with an anode devised in a similar fashion. The resulting battery is said to be the most powerful in the world, avoiding the usual trade-off between longevity and power while having a footprint of just a few millimeters. By altering its composition, scientists can even optimize the contraption for more juice or increased life. It's expected that the technology could make devices 30 times smaller and help broadcast radio signals up to 30 times farther, but it'll still be a while before it winds up in a super-slim phone within your pocket. For now, the researchers have their sights set on integrating the tech with other electronic components and investigating low-cost manufacturing.

  • WSJ: Airbus to drop lithium-ion batteries from A350 to meet delivery schedule

    Amidst the ongoing brouhaha over rival Boeing's Dreamliner-grounding battery troubles, Airbus has decided not to use lithium-ion batteries in its newest aircraft, the A350, according to industry officials cited by the Wall Street Journal. The European plane maker is said to be making the change in an effort to stick to its plan of pressing the jet into commercial service by the middle of next year. While the craft's early test flights this summer will still make use of four lithium-ion batteries for on-ground electrical power and as backup in the air as originally intended, it will be delivered to airlines with conventional nickel-cadmium batteries instead. Safety considerations are undoubtedly part of the picture, but since the A350 is already behind schedule by a couple of years, its manufacturer can't afford any further delays -- anticipated in case regulators find fault with the use of lithium-ion packs in flights. As Boeing struggles to find a fix and get the 787 back into the air, it seems Airbus has taken the easy way out. [Image credit: Airbus S.A.S / H. Goussé]

  • WSJ: Boeing readying battery tweaks for 787 Dreamliners

    The Wall Street Journal has gotten word that Boeing is preparing tweaks to its 787's lithium-ion batteries that could minimize the risk of fire and let its Dreamliners take to the skies before a long-term solution is sussed out. Citing industry and government officials, the WSJ says the modifications will see a larger separation between battery cells in an effort to lessen the risk of heat and fire spreading. Other measures may include keeping cells more firmly in place to prevent them from moving about and interfering with electronics, incorporating heat sensors and a beefed-up battery cover that could contain flames and chemicals. Changes to the aircraft aren't nailed down across the board just yet, and they still need approval by Japanese and American regulators before they can be applied. According to one of the WSJ's sources, a best-case scenario could see Dreamliners put back on passenger flight duty in March. [Image credit: Martin Deutsch, Flickr]

    Battery nerds rejoice: Panasonic has cobbled together an electronic torch that will play nice with almost anything in your collection. The Any Battery Light can siphon power from AA, AAA, D and C-sized batteries, lighting the dark with just a single serving of any compatible size. Loading it up with all four provides up to 86 hours of continuous LED illumination. Not all batteries are equal, of course -- a single AAA isn't going to shine as brightly as its thicker cousins, and users will need to manually flip a switch to choose what size battery the torch draws its light from. Japanese consumers will be able to pick one up for about ¥2,000 ( $23) in red or white later this month.

  • Nissan upgrades US Leaf warranties, will 'restore' batteries that lose too much charge

    Nissan has thrown down the warranty gauntlet to other EV makers by announcing it would be the first to "restore" battery capacity if a Leaf's full charge fell below 9 out of 12 "bars" within 5 years or 60k miles. The new clause was announced by VP Andy Palmer and will go into effect in spring of next year on all models, including those sold in 2011 and 2012. The company stressed it would only "repair or replace the battery under warranty with a new or remanufactured unit to restore capacity at or above a minimum of nine bars," and not a full charge -- saying a gradual, but not excessive loss of charge was normal. Nissan added that it'd look to improve the accuracy of the battery gauge, since the aforementioned bars on the dash were computer managed and not exactly scientific. All of this applies to US-only vehicles for now, but similar policies will soon go into effect worldwide, according to the statement. So, if you've been starting to get range anxiety, check the PR below the break for more info.

  • Scientists develop eco battery powered by root-extracted dye

    Scientists have been figuring out how to develop eco-friendly ways of recharging batteries for years, from harvesting temperature fluctuations to harnessing your fidgets. But perhaps a better solution is to create a different kind of battery altogether; one that uses greener sources instead of finite ingredients like cobalt. That's exactly what the whiz-kids from the City College of New York, Rice University and the US Army Research Laboratory have done with a new lithium-ion battery powered by red dye extracted from madder roots. Called rose madder or purpurin, the dye was apparently used in ancient civilizations for dying fabrics in oranges, reds and pinks. Fortunately for the future of the battery, it turns out its color molecules are also carriers of carbonyl and hydroxyl groups that make it ripe for use as an electrode and that purpurin is far easier to process than other organic materials: "These aromatic systems are electron-rich molecules that easily coordinate with lithium," said CCNY Professor George John. It'll likely take years before we'll get to the point of mass production of these things, but in the future we could finally say that batteries do indeed grow from trees.

  • Fisker Karma production has been halted for a month, A123 Systems' bankruptcy to blame

    Fisker Automotive is certainly no stranger to hold ups, and it turns out they've had another: production of the firm's Karma hybrid has been halted since its sole battery supplier, A123 Systems, filed for bankruptcy in October. Since A123 slowed its battery output after the filing, the automaker has been too short on batteries to continue churning out vehicles. Fisker anticipates resuming production after the ill-fated outfit is auctioned off, but it doesn't expect to know the outcome of the sale until mid-December. If your Karma's lithium-ion pack goes kaput in the meantime, there's still hope. As of now, the company says it has enough batteries in stock for customers who need replacements.

    So far your footsteps, breath and nervous energy have all been tapped to charge up batteries, and now researchers from the Georgia Institute of Technology scientists have pulled it off using thermal changes. They did it with so-called pyroelectric nanogenerators, which use polarization changes to harvest heat energy from temperature fluctuations. Normally output current is too low for commercial electronics, but by making one with lead zirconate titanate (PZT), the team was able to create a device that could charge a Li-ion coin battery to power a green LED for a few seconds. The researchers predict that by doubling the surface area, they could drive wireless sensors or LCDs using only environmental temperature changes from an engine or water pipe, for instance. The result could be green power, but without all that pesky moving around.

    If you're the fidgety type, new research from Georga Tech may one day turn your nervous energy into a fully charged cellphone. The scientists, who previously borrowed piezoelectric power from walking, created static electricity generated from movement between plastic and metal, similar to the way a balloon can be electrified by rubbing it on your hair. The charging area was greatly increased by patterning the surfaces on a nanoscale level, allowing this "tribolectric effect" to be multiplied and converting up to 15 percent of the mechanical energy into electricity (so far). About 50 common materials could be paired to create the material, and a 2 x 2-inch patch could conceivably be worn as an armband and used to charge up a cellphone battery. So far the tech works fine in the lab, but it remains to be seen if real world vibrations can generate enough energy to make it practical. While you're waiting, though, feel free to stock up on coffee.

    Is your cell phone dead and there's nary an outlet in sight? It's not an issue if you're feeling zesty and also toting a BoostTurbine hand charger, which Eton just announced as part of its new portable charger lineup. The BoostTurbine2000 and 1000 model numbers denote the mAh of the batteries in each device, which can borrow volts from a conventional outlet, then transfer up to a full or half charge (respectively) to most smartphones. In a pinch, though, you can pop out the hand-crank and grab about 30 seconds of call time for each minute of sweat equity, according to the company (depending on your motivation, natch). The BoostTurbine2000 will set you back $59 while the 1000 model will run $49, and both are now available at Eton's store. The company also outed a new line of regular plug-in portable chargers -- it's all in the PR after the break.

    On Wednesday night, Stanford Ovshinsky, inventor of the nickel-metal hydride (NiMH) battery, passed away at the age of 89 due to complications from cancer. The Akron, Ohio native may not be a household name, but there's a good chance that many of your electronics have been powered by his work, as NiMH batteries are used in everything from mice to hybrid cars. A self-taught inventor who didn't attend college, Ovshinsky held hundreds of patents, received a number of honorary degrees and is even the namesake of a branch of electronics dubbed Ovonics. Flat-panel displays, solar cells and even phase change memory are just a handful of other technologies that his work helped to develop. Next time you pick up a modern gadget, just remember that Ovshinsky is partly responsible for its existence. [Image credit: Joi Ito, Flickr]

  • NC State nanoflowers can boost battery and solar cell capacity, 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 at the University of California San Diego have devised new algorithms that could 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 $415,000 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 $4 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." Update: UC San Diego reached out to let us know that they were awarded $415,000 (not $460,000 as previously noted) out of a grant totaling $4 million (not $9.6 million), split between Bosch and Cobasys. We've updated the post and the press release below to reflect the correct figures.
