Recently Torrance, CA based CALEB Technology and LA/Brea, CA based California Lithium Battery signed an MOU to establish a Joint Venture to produce a new line of safe ultra-high performance lithium ion batteries for consumer electronic devices, power tools, and electric vehicles (EVs). Los Angeles, CA (PRWEB) July 18, 2014 As the global demand continues to grow for a safe, affordable, high energy density lithium-ion battery (LIB) two recognized Southern California advanced battery...

How To Make More Efficient Fuel Cells
2014-07-10 03:09:31

By Glen Martin, Stanford School of Engineering Using high-brilliance X-rays, researchers track the process that fuel cells use to produce electricity, knowledge that will help make large-scale alternative energy power systems more practical and reliable Solar power and other sources of renewable energy can help combat global warming but they have a drawback: they don't produce energy as predictably as plants powered by oil, coal or natural gas. Solar panels only produce electricity...

Lithium-sulfur batteries last longer with nanomaterial-packed cathode Electric vehicles could travel farther and more renewable energy could be stored with lithium-sulfur batteries that use a unique powdery nanomaterial. Researchers added the powder, a kind of nanomaterial called a metal organic framework, to the battery's cathode to capture problematic polysulfides that usually cause lithium-sulfur batteries to fail after a few charges. A paper describing the material and its...

Energy Converted And Stored In Single Unit Using Self-charging Power Cell
2012-08-21 14:42:59

Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries. At the heart of the self-charging power cell is a piezoelectric membrane that...

Some of the planet´s tiniest inhabitants may help address two of society´s biggest environmental challenges:  how to deal with the vast quantities of organic waste produced and where to find clean, renewable energy. According to César Torres and Sudeep Popat, researchers at Arizona State University´s Biodesign Institute, certain kinds of bacteria are adept at converting waste into useful energy.  These microorganisms are presently being applied to the...

Rice researchers develop paintable battery
2012-06-29 05:30:54

[ Watch the Video ] Michael Harper for redOrbit.com — Your Universe Online Researchers at Rice University in Houston, Texas have put their minds together to create an incredibly thin battery. So small, in fact, if can be painted on the surface of whatever it´s meant to power. This rechargeable lithium-ion battery is applied in layers, recreating the components of a traditional battery. Rice scientist Pulickel Ajayan helped to create the sprayable battery and posted the...

The sun doesn't always shine and the breeze doesn't always blow and therein lie perhaps the biggest hurdles to making wind and solar power usable on a grand scale. If only there were an efficient, durable, high-power, rechargeable battery we could use to store large quantities of excess power generated on windy or sunny days until we needed it. And as long as we're fantasizing, let's imagine the battery is cheap to build, too. Now Stanford researchers have developed part of that dream...

Engineers at Case Western Reserve University have made an electrochemical cell that uses a plasma for an electrode, instead of solid pieces of metal. The technology may open new pathways for battery and fuel cell design and manufacturing, making hydrogen fuel and synthesizing nanomaterials and polymers. A description of the research is now published in the online edition of the Journal of the American Chemical Society at http://pubs.acs.org/doi/abs/10.1021/ja207547b. "Plasmas formed...

Hybrid energy storage device is as small as it can possibly get The world at large runs on lithium ion batteries. New research at Rice University shows that tiny worlds may soon do the same. The Rice lab of Professor Pulickel Ajayan has packed an entire lithium ion energy storage device into a single nanowire, as reported this month in the American Chemical Society journal Nano Letters. The researchers believe their creation is as small as such devices can possibly get, and could be valuable...

Texas-A new low cost test for acute pancreatitis that gets results much faster than existing tests has been developed by scientists at The University of Texas at Austin. The sensor, which could be produced for as little as a dollar, is built with a 12-cent LED light, aluminum foil, gelatin, milk protein and a few other cheap, easily obtainable materials. The sensor could help prevent damage from acute pancreatitis, which is a sudden inflammation of the pancreas that can lead to severe stomach...

Vladimir Kozmich Zworykin (July 30, 1889 - July 29, 1982) was a Russian-American engineer, inventor, and initiator of television technology. One of his accomplishments includes the invention of a television transmitting and receiving system utilizing cathode ray tubes. In the early thirties, he was instrumental in the physical production of components used in the television, including charge storage-type tubes, infrared image tubes, and the electron microscope. Although many biographers...
