Korean, carboncoated lithiumion battery could cut recharge times down to minutes

Anyone who's had to recharge an EV -- or, for that matter, any mobile device with a very big battery -- knows the pain of waiting for hours while a lithium-ion pack tops up. South Korea's Ulsan National Institute of Science and Technology has developed a conduction technique that could cut that charging time down to less than a minute. By dousing the nanoparticle materials of the battery in a graphite solution that's then carbonized, the researchers make a web of conductors that all start charging at once; current batteries have to charge towards the center slowly, like a not-very-edible Tootsie Pop. The immediate goal is to develop a secondary battery for an EV that could provide extra mileage in a matter of seconds. Here's hoping that the Ulsan team's fast-charging battery is more viable than others and spreads to just about everything -- we'd love to have EVs and laptops alike that power up in as much time as it takes to fill a traditional car at the pump.

Samsung HM5100 Bluetooth S Pen makes a surprise debut in our Note 10.1 'press kit,' we pencil in a chat (hands-on)

Samsung HM5100 Bluetooth S Pen makes a surprise debut in our Note 101 'press kit,' we pencil in a chat handson

Hidden among the higher-profile items at Samsung's Galaxy Note 10.1 launch today was a device that at first seemed familiar, but turned out to be far more than your everyday S Pen. That's right, Samsung's already capable stylus just got a major boost -- meet the BT S Pen. The device, which received no formal introduction during its host device's launch event, first appeared in the "press kit" bag that attendees received on the way out the door. It's similar in size and shape to the company's Galaxy S Pen Holder Kit, which serves as a sleeve for the standard-issue Note S Pen, but Bluetooth functionality, along with a microphone and tiny speaker, enable the lightweight plastic contraption to double as a wireless headset -- sure to come in handy with the SIM slot-equipped international Note 10.1 flavor.

We caught our first hint of the pen's functionality upon discovering a bundled AC adapter -- that seemed mighty odd. The box also included an unusually beefy user manual and no fewer than five replacement "nibs" (read: stylus tips). Pairing took but a few seconds, and then we were on our way answering calls with a single tap of the talk button. There's also a built-in vibration mechanism, which serves to alert you to incoming calls. Sound quality was solid, but speaking into a pen admittedly felt a bit odd -- you may not draw as many stares as you would if speaking directly into a 10.1, but the seemingly unusual action may still turn a few heads. Otherwise, the S pen functioned as expected.

The packaging is all we have to go off of at this point -- Samsung reps we spoke to didn't know to expect the device today, so there's no pricing or availability info to share. We do know that the it's rated for three hours of talk time and 130 hours of standby, it weighs 21 grams, offers Bluetooth 3.0 compatibility and will work with Galaxy Note devices -- you could use it as a headset with other gadgets, though there wouldn't be much appeal. It also includes a micro-USB charging cable, with the port accessible just above the shirt clip. That's all she wrote for now -- apparently this accessory was available exclusively at today's event, and may not make its way to the US, if it's released at all. You can see it in action now though, in our hands-on video after the break.

Leaked photo allegedly shows iPad mini's dock connector flex cable with headphone jack on bottom

Leaked photo allegedly shows iPad Mini's dock connector flex cable with headphone jack on bottom

Granted, the existence of a 7-inch iPad mini is far from confirmed, but the latest "evidence" to fan those rumor flames is a photo of what appears to be a dock connector flex cable that connects the smaller dock connector, headphone jack and home button connector. The photo appeared on the site Nowhereelse.fr, which also recently published photos that purportedly show the next-gen iPhone's tiny docking connector. Other reports have indicated that the iPad mini's headphone jack will be located on the top of the device (as it is on the current version of the tablet) as opposed to on the bottom, which would contradict this latest leaked photo, but this new layout corresponds to rumors about the iPhone 5. The one semblance of certainty in all this? iFixit's Kyle Wiens weighed in to say that the component "is consistent" with Apple parts.

This is the Modem World: whatchoo got under the hood?

Each week Joshua Fruhlinger contributes This is the Modem World, a column dedicated to exploring the culture of consumer technology.

DNP This is the Modem World whatchoo got under the hood

I just bought a new car. I chose an automatic transmission. I know, I know. In order to really appreciate driving, one must have three pedals and be in complete control of his torque curve.

But I do love driving and can hold my own in a conversation about horsepower, suspensions and cold-air intakes. As for working on cars, I could change my oil, but nothing more. In my teens, I drove a manual 1980 VW Rabbit that I took from Orange County to LA and back again almost every weekend. I loved the car, but after years of stop-and-go, my clutch leg grew giant-sized, like a crab. I promised myself to never sit in traffic in a manual transmission again.
