Capacitors supports 10k recharge cycles
An 18-year-old student, Eesha Khare, has reportedly developed a new form of energy storage, referred to as a supercapacitor, that promises to recharge a cellphone in 20 to 30 seconds. The research project landed Khare a $50,000 scholarship and an Intel Foundation Young Scientists Award at the Intel-sponsored International Science and Engineering Fair, along with a $5,000 "best of category" award and another $3,000 prize in the chemistry division.
Adds 2,100mAh battery
Accessory maker Mophie has launched an iPhone 5 version of the Juice Pack Plus. The new case adds a 2,100mAh battery, which can roughly double the usable life of an iPhone. It in fact holds slightly more power than the Plus for the iPhone 4/4S, which is rated at 2,000mAh.
Extends life of iPad, other devices
It's not often an iPad case comes with a manual, even a short one, but it seems like an increasing number of models include some form of electronics. The Props Power Case needs a manual for its integrated lithium ion battery -- we received an 8,000mAh unit, although a 12,000mAh model is also available. In our review, we'll test how well the case works as both protection and a power supply.
Two other Chinese firms step up to fill in on iPad, MacBook batteries
A report in China Business News claims that Samsung SDI, the company's battery-producing subsidiary, has decided to withdraw from selling batteries to Apple, possibly in retaliation for various moves the iPad maker has made to reduce its dependence on Samsung as a supplier. Two other Chinese firms, Tianjin Lishen Battery and Amperex Technology, are said to be filling in for Samsung's absence in the iPad and MacBook lines of batteries, which Samsung SDI formerly supplied.
Tango uses rare tilting back
Continuing a series of CES announcements, XtremeMac has announced the Tango TT, a new speaker dock for iOS devices.

It also features a flexible dock connector, which lets iOS devices (including iPads) sit in the dock in portrait or landscape orientations.
Replaces batch that had defective batteries
Apple is now shipping replacement iPod nanos to customers who had Nanos from a certain batch in the first-generation production run that have been shown to have defective batteries that could, in rare circumstances, overheat or even catch fire. The new units are exactly the same as the replacements, and not brand new iPod nanos (which now hold 8GB or 16GB) as some had hoped. The original Nanos came in 1, 2 or 4GB capacities.
Second investigation launched into L-Ion batteries
The US National Highway Traffic Safety Administration (NHSTA) is reportedly looking into the safety of lithium-ion batteries used in electric automobiles. The action identified by Bloomberg tipsters comes in the aftermath of a recent battery fire involving a Chevy Volt. The scope of investigation will most probably include plug-in vehicles from Nissan and Ford, as well as other General Motors subsidiaries.
Greener tech fo Apple portables?
Two newly-published Apple patent applications suggest an unexpected Apple interest in hydrogen fuel cells, AppleInsider notes. The first, Parallel fuel stack architecture, suggests a way of arranging cells into a stack. A common problem with stacks is said to be a tendency toward a single point of failure in a connected series. There can also be many kinds of vulnerabilities, such as degradation of the electrolyte, accumulation of nitrogen in the anode, and water flooding in the anode or cathode. The reliability of stacks can go down as the number of cells grows, Apple comments.

MBP battery swap costs
Apple has confirmed the pricing and steps needed to replace the battery in the new 17-inch MacBook Pro, a report indicates. Due to a new power-efficient design, the battery cannot easily be replaced by owners; instead, an Apple spokesperson says, people will have to bring their Pros to an Apple Store or an authorized reseller, where they will pay a fee of $179. This should cover the cost of installation, the new battery, and safe disposal of the old battery.
Apple battery controversy
Developing European Union guidelines could force Apple to adopt a more user- and environmentally-friendly approach to batteries, reports say. The legal body is currently in the process of drafting a "New Batteries Directive," which would expand on the present set of guidelines designed to make it easier to remove, dispose of and/or recycle old batteries. The present directive indicates that companies must make it simple to remove batteries from electronics; the proposed one would insist that batteries can be "readily removed" for replacement or disposal.
QuickerTek MacBook battery
QuickerTek has announced a new external battery/charger for the MacBook and 15-inch MacBook Pro. The battery provides users between 8 and 10 extra hours of usage, on top of what a MacBook's internal battery already provides. The casing appears to be brushed aluminum, allowing it to blend in with other Apple products, and features an LED charging status indicator.
ASUS Eee PC batteries
Consumers who bought ASUS' Eee PC 900 in Hong Kong are accusing the company of misleading them.

The company is now giving a free battery upgrade to buyers who purchased the Eee PC 900 on its launch date.
Argonne Composite Battery
Researchers at Argonne National Laboratory in Argonne, IL claim to have developed composite battery materials that will increase battery life by up to 30 percent, as well as making them safer and last longer than conventional lithium-ion batteries. The new batteries, based on a new generation of lithium-ion electrode chemistry, are similar to the ones GM is developing for its Chevy Volt electric vehicle, but Argonne is likely to market its technology to extend the usefulness of laptops and cell phones.
FastMac 17" MBP battery
Upgrade specialist FastMac has announced a new upgraded notebook battery, designed specifically for the 17-inch MacBook Pro. By swapping it with the default unit, owners are said to gain extended battery life, over and above the 5.75 hours promised by Apple. Along those lines, the FastMac battery is rated at 71Wh, surpassing Apple's 68Wh figure. Both batteries, however, use lithium-polymer cells, and have LED lights to indicate charge status. The new FastMac model should ship within 10 days, and can be pre-ordered now for $100; this is said to be $30 cheaper than a replacement from Apple.
Luggage lithium ban
Within days, air travellers will no longer be able hold loose lithium batteries in their luggage, the US Department of Transportation says. As of January 1st, batteries will either have to be inserted into a phone, notebook or other electronic device, or else dropped into a plastic bag, and bundled along with carry-on baggage in a limit of two batteries per passenger.
The issue, according to the Federal Aviation Administration, is that if a lithium battery catches fire while in a cargo hold, current extinguishing systems are unable to stop the blaze. The National Transportation Safety Board insists that it cannot rule out lithium as the source of a plane fire at the Philadelphia International Airport in 2006.
