\"IonCrossing_x\"<\/p>\n

A group of researchers at University of Illinois at Urbana-Champaign<\/a> have created microbatteries that charge 1,000 times faster than normal batteries and can, feasibly, “jump-start a car” while powering a cellphone. The group, led by William King<\/a>, is working on shrinking the batteries down to fit inside a “credit-card thin” device. <\/p>\n

The batteries use a design that offers a much larger surface area for the cathode and anode which improves discharge as well as charge rate. While cathode (or plus side) improvements have existed for a while, this is the first one that also improves the “minus side” or anode.<\/p>\n

In practice, the batteries could help create devices last 30 times longer or transmit farther distances – albeit with a hit in battery life. Many batteries either have a high power – the ability to pump out a lot of juice quickly – or high energy – the ability to store that juice and mete it out. Capactitors, for example, charge quickly but express their power very quickly as well. Li-Ion batteries hold energy but take a long time to charge. Because these batteries can hold so much energy and charge so quickly, you get the best of both worlds. <\/p>\n

“Now we can think outside of the box,” said James Pikul, a graduate student on the project. “It\u2019s a new enabling technology. It\u2019s not a progressive improvement over previous technologies; it breaks the normal paradigms of energy sources. It\u2019s allowing us to do different, new things.”<\/p>\n

You can read the paper here<\/a> but be warned it’s a bit nerdy and bit pricey to download. <\/p>\n
