Stanford scientists give new life to Thomas Edison's nickel-iron battery

By - July 8, 2012 6 Pictures
A green, rechargeable battery that is suitable for powering electric vehicles and stationary power storage applications, and that would survive tens of thousands of charge cycles in a useful life of 100 years without loss of capacity. What could be a better innovation for our times? Such a battery has been developed, and recently improved by Stanford researchers. Oh, one other thing. The battery was invented by Thomas Edison in 1901. Read More

Spray-on lithium-ion batteries could shape the next generation of portable electronics

By - June 30, 2012 6 Pictures
While battery technology has come a long way in recent years, it still places constraints on the size and shape of cellphones and other personal electronic devices. Researchers at Rice University are looking to solve this problem by developing a rechargeable lithium-ion battery that can be painted on virtually any surface ... and early results are promising.

Plug + Play is a winning formula for an electric vehicle charging station

Design By Many, a challenge-based design community, recently announced the winners of its Electric Vehicle Charging Station competition. First prize was awarded to the HMMY team for its Plug + Play concept. The smart-looking electric vehicle charging station attempts to stimulate awareness of the gap between production and consumption of energy. The design "generates a renewed consciousness of energy use in our modern lives," according to HMMY. Read More

AQUA TEK S – the first waterproof, ruggedized, solar-powered battery case for iPhone

By - February 15, 2012 5 Pictures
If you're hoping to attract investors to get yet another iPhone case to an already crowded market, it had better do more than just protect a phone from bumps and scrapes. Snow Lizard Products is giving itself the best possible chance of raising funds for its new AQUA TEK S case for iPhone 4 and 4S with an offering that not only boasts ruggedized protection, but also includes a solar panel, built in battery, and is waterproof up to 20 ft (6 m).

New GreenZero chargers eliminate vampire power drain

By - January 3, 2012 4 Pictures
The spring-loaded PumPing Tap concept that would eject electrical plugs from an outlet when not actively drawing electricity attracted a fair share of criticism from readers when we looked at it earlier this week. Bracktron has come up with a more practical solution with its line of GreenZero chargers that detect when the device being charged is unplugged or fully charged and automatically shut off to eliminate stand-by – also known as vampire power – consumption.

Sony demos paper-fueled battery

By - December 21, 2011 1 Picture
We've heard of gadgets being powered by some pretty crazy stuff, but how about paper? Sony recently showed off a new bio-cell battery that breaks down paper in order to create power. A paper battery sounds a little bit far-fetched, but the technology works, and could potentially change how we power devices in the future. So how does it work? The process starts with an enzyme suspended in water. When paper is dropped in, the enzyme starts to break it down and produce glucose that can then be harvested and used to power a battery. Sony described the break down process as similar to how a termite might eat and break down wood. Read More

Transparent and flexible lithium-ion battery developed

By - July 27, 2011 5 Pictures
There have been numerous attempts at designing partially transparent gadgets over the years, with the LG GD900 cell phone being a notable example. Fully translucent mobile devices are difficult to produce, however, as they would require a fully see-through battery, which hasn't been available yet. Stanford University researchers now claim to have developed such a device - a see-through, flexible, lithium-ion battery, suitable for powering mobile gadgets like cell phones, tablets or e-readers.

iCruiser battery pack juices up mobile devices

By - July 5, 2011 4 Pictures
Smartphones, tablets and media players have helped to make our mobile existence so much more tolerable - but they all suffer from varying degrees of the same problem. Battery life is always a nagging concern for regular travelers, leading many to carry some form of external portable power source like the Juice Pack Powerstation we reviewed recently. Even though Mophie's external battery pack proved its worth in our tests, we may just have to trade it in for the New Trent iCruiser IMP1000 - which offers over three times the battery capacity in a similar-sized format and claims compatibility with almost every device in the market.

New discovery might lead to laptops powered through typing

By - June 23, 2011 1 Picture
Everlasting batteries and self-powering portable electronics have come one step closer to reality, according to the results of a new research by Australian scientists from Royal Melbourne Institute of Technology (RMIT). The group of researchers successfully measured piezoelectric thin film’s capability to turn mechanical pressure into electricity. It may sound like an idea from the realm of science fiction, but the discovery could eventually lead to laptops powered through typing. Read More
