Flexible, fast-charging aluminum-ion battery offers safer alternative to lithium-ion

By - April 9, 2015 1 Picture
Researchers at Stanford University have created a fast-charging and long-lasting rechargeable battery that is inexpensive to produce, and which they claim could replace many of the lithium-ion and alkaline batteries powering our gadgets today. The prototype aluminum-ion battery is also safer, not bursting into flames as some of its lithium-ion brethren are wont to do. Read More

Breitling B55 Connected watch puts smartphone at its service

By - March 15, 2015 5 Pictures
Is the mobile phone threatening to kill off the wristwatch? Not if Swiss watchmaker Breitling has anything to say about it. With an apparent motto of "if you can't be 'em, then make 'em work for you," the Breitling B55 Connected combines smartwatch technology with haute horlogerie in a partnership where the phone serves the watch instead of the other way round.

Tesla gearing up for release of batteries for the home

By - February 25, 2015 1 Picture
The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle. Read More

New water-based organic battery is cheap, rechargeable and eco-friendly

By - June 29, 2014 1 Picture
Lithium-ion batteries have made portable, rechargeable electronics commonplace. Unfortunately, they do have some glaring drawbacks, including heat issues, being made with rare, toxic elements, and the fact the technology doesn't scale up very well, which limits applications. A team of scientists at the University of Southern California (USC) is working on an alternative in the form of a water-based organic battery that is not only cheaper and more environmentally friendly, but also holds the potential for scaling up for use in wind and solar power plants as a means to store large amounts of energy.

Caseboard electric skateboard knows when to fold 'em

By - June 19, 2014 11 Pictures
Electric skateboards can be a great way to get around town, but it's a different story when it's time to get off the board. The battery and motor that make things so cruisy when the board is underfoot have the opposite effect when its tucked under your arm. And it's not just the weight, with electric skateboards generally featuring a longboard form factor that can be unwieldy to carry. That's why Adam Riley of Epic Skateboards has developed the Caseboard, an electric skateboard that folds in half for carrying like a briefcase when not getting users from A to B. Read More

Graphene and carbon nanotubes combined to create flexible, wearable supercapacitor

By - May 15, 2014 3 Pictures
An international team of researchers has developed a supercapacitor composed of graphene and carbon nanotubes that is claimed flexible enough to be woven into clothing and potentially powerful enough to offer a real alternative to batteries for use in portable devices. Capable of being charged and discharged in excess of 10,000 cycles, the new supercapacitor also promises to be significantly lighter, faster to charge, and more robust than current battery technology.
