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.

Droid Bionic gets extended battery treatment, proudly struts its freshman 15 (video)

As you’re aware, the Droid Bionic features a 1735mAh battery that provides a slight bump in capacity over its competition — namely the Droid Charge and Thunderbolt. Still, if you plan to push this LTE powerhouse beyond moderate usage, you’ll likely find yourself in a feverish hunt for wall outlets before the day is through. Now, Android Central gives us a peek at the Bionic’s extended battery, and so long as you’re willing to live with the (super obvious) protrusion, you’ll find the latest Droid riding high with a 2760mAh cell. Perhaps it’s not the sleekest solution in the world, but hey, at least it’s not quite so insulting as the extended battery on Verizon’s first LTE handset — take a peek at the video after the break for a comparison.

Mophie cuts the price on the Juice Pack Boost and Powerstation, raises the battery capacity

Most companies here at IFA figured if they were going to haul it all the way to Berlin, they might as well unveil their products on a stage — you know, with some prepared remarks, a press release and maybe some disco music to get people pumped (okay, we haven’t been subjected to that yet). But not Mophie. The company has a habit of releasing its products quietly, demonstrating its unannounced wares in plain sight. That’s how we happened upon the newest versions of its Juice Pack mobile chargers, the Boost, Powerstation and Reserve. Of the three, the latter got the biggest makeover, with a more compact shape and a pop-out USB connector that’s attached to a plastic cable. As a result of that diet, though, it now has a battery capacity of 700mAh, not 1,000mAH, although its price is about to go up to $35 from $30. The good news is that Mophie lowered its prices for the other two, all while expanding the battery capacity. The Powerstation now has a 4,000mAh battery and costs $80 (down from $100) while the Boost is rated for 2,000mAh and costs $49.95 (a $10 price cut). In case you’re interested in this sort of thing, we’ve got hands-on photos below, and Mophie says the lot will hit the Apple Store in about two weeks.

S-Walker Electric Transporter hands-on (video)


In an IFA galaxy far far away lives the China Pavilion. And on the far side of the outer ring of the China Pavilion, buried amongst a plethora of steamers, curling irons, and television mounts, you may stumble upon the S-Walker — though you’re just as likely to miss it. And what might an S-Walker be? Well, if we’re being precise, it’s a “Speed-Walker, Sky-Walker, whatever,” according to its German booth master. Luke would be proud. Lesser beings may recognize it as a KIRF Segway, designed in Germany and handmade in China, just a mere ten days ago. Its biggest strength lies in price — the thing is expected to retail for €2,500 (about $3,550) sometime in the middle of next year. We suppose this yet-to-be-released electric transporter is here to serve warehouse workers, couriers, and the millions of college students who every day dream of zooming across campus atop a pair of motorized wheels, but simply couldn’t justify spending an entire semester’s tuition on a Segway.

We spent a few minutes riding the world’s first (and only) functional S-Walker around the rather deserted International Hall, and while very much still a prototype, the battery powered contraption felt peppy enough and responded accurately to commands, moving forward as we leaned to the front, and backing up as we shifted weight to the rear. You control direction using a small handlebar-mounted joystick, rather than by leaning from side-to-side as you would on a Segway. The designers capped speed at 10 kilometers per hour for the IFA demo, but production models will be boosted to 30 km/h, and it’s theoretically capable of reaching 100 km/h (but that’ll likely require some potentially-illegal hacking on your part). Roll on past the break to see the S-Walker in action. And may the force be with you.

Nissan Leaf mod offers more accurate battery status, less streamlined interior

Car mods come in many forms — including, even, a piece of cardboard with some switches and an LED display. The car being modded in this case is the Nissan Leaf, and the mod in question (still in its temporary form here, thankfully) is a simple but important one. It’s a homebrew device that plugs into the Leaf’s OBD-II diagnostics port and displays the battery’s exact state of charge, as opposed to the somewhat less specific bars that are displayed on the main dashboard display. Absolutely necessary? Not exactly, but the mod seems to be catching on with a growing contingent of DIY-minded Leaf forum members. Hit the source link below for a few more examples and some additional details for building your own.

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? Check out the full PR after the break.

Australian soldiers will be solar-powered

Soldiers carry a lot of gear when out in the field. The load would be backbreaking for anyone without the necessary strength and training. Of course, on top of all the gear, modern soldiers need to carry battery packs as well, including different battery packs for different items. Researchers at the Australian National University have […]

Sony intros 200-pound battery to power businesses, government agencies during a blackout

In the five months since a tsunami and 9.0 magnitude earthquake hit Japan, we’ve seen various technology companies struggle to get their manufacturing operations back in order, but Sony appears to be the first to introduce a product seemingly inspired by the disaster itself. The outfit’s Japanese division just announced the ESSP-2000, a 90kg (198-pound)battery whose 2.4kWh of power should keep businesses and government agencies afloat for at least a few hours in the event of a blackout or natural disaster. All told, the battery can support a maximum load of 1000VA, and can recharge to 95 percent in about two hours — not bad, considering the capacity of this thing. Sony also went with olivine-type lithium-ion iron phosphate batteries, which it says will last ten years. With a price of ¥2 million ($25,700), this battery’s clearly not meant to be a savior for home users, though for businesses it could be a small price to pay for an uninterrupted power supply.
