EV Battery Maker A123 Dropping Fast, Funding Needed

Posted by Boniface Ndirangu in Energy Storage, Green Economics on May 18, 2012

There are sharp declines in the financial position of lithium-ion battery manufacturer A123 Systems, fanning in a lot of heat on this 10-year-old company founded and based on technology developed at MIT. To have a more clear picture of how terrible the situation is A123 just posted a $125 million net loss in its most [...]

Yi Cui’s New Silicon Nanotube Batteries Can Get Recharged Up to 6,000 Times

Posted by Boniface Ndirangu in Energy Storage on May 16, 2012

Yi Cui, a Stanford scientist and founder of Amprius, is working on a high-tech lithium ion battery that could last for 6,000 charge and discharge cycles – all without degrading itself below 85 percent. This could bring an end to the headaches that many go through with aging laptop batteries or electric cars which just [...]

New Grid-Ready Aqueous Lithium Ion Battery to Be Developed in German University

Posted by Ovidiu Sandru in Energy Storage on February 28, 2012

Although they’re being touted as the perfect energy storage medium for electric cars, lithium ion batteries, in the form they exist today, are not as good for grid energy storage applications. Dr. Fabio La Mantia from the Ruhr-Universität Bochum – Germany is going to develop an aqueous lithium ion battery adapted perfectly for the electrical grid. [...]

MRI Used to See Inside Batteries

Posted by Ovidiu Sandru in Energy Storage on February 13, 2012

I bet you knew MRI (Magnetic Resonance Imaging) is used to see what’s inside your brain, didn’t you? Well, its applicability is no longer limited to the human body, because MRI can now be used to diagnose batteries so scientists can see their defects without opening their carcase. A team of scientists from Cambridge, SBY [...]

New Lithium Ion Battery Embedded in Cotton Fabric Could Save Lives

Posted by Ovidiu Sandru in Energy Storage on February 6, 2012

Flexible batteries could be the future devices that power our gadgets, emit distress signals in the case of an emergency or even resuscitate a dying patient. Woven into fabrics, they can reach extreme applications, but also have to withstand extreme conditions like washing and ironing. A team at the Polytechnic School of Montreal in Canada led [...]

Russia Builds Liotech, World's Largest Lithium Ion Battery Factory

Posted by Ovidiu Sandru in Energy Storage on December 21, 2011

Some say the Chinese have the brightest minds in the world, an impressively high level of technological achievements (even though some are done by copying others), and that Russian things are ultimately the ones built to last. What could be better for the EV industry than the world’s largest lithium ion battery factory built in [...]

German Researchers Dramatically Improve Electrolyte Filling Time in Batteries, Reduce Costs

Posted by Ovidiu Sandru in Energy Storage on October 17, 2011

A discovery made by researchers at the Karlsruhe Institute of Technology (KIT) can eventually make lithium ion batteries cheaper by improving a key process that currently takes a lot of time to complete: filling the batteries with liquid electrolyte. The porous electrodes inside modern rechargeable batteries have to be properly filled with liquid electrolyte. Actually, [...]

New Conductive Glue Enhances Lithium Ion Battery Capacity by 30 Percent

Posted by Ovidiu Sandru in Energy Storage on October 3, 2011

Currently, lithium-ion battery electrodes are made of graphite – we all know their performance. Silicon electrodes, on the other hand, could theoretically hold up to 10 times more lithium than graphite and around 30 percent more electricity for that matter. The problem with silicon electrodes is that they swell when lithium enters them (the battery [...]

New Solid State Lithium Ion Batteries As Good As Liquid Ones, And Cheaper

Posted by Ovidiu Sandru in Energy Storage on August 3, 2011

A new solid state lithium battery has been recently invented by Japanese researchers. The cell performs just as well as regular lithium ion batteries, but instead of having a liquid electrolyte, it features a solid one. The advantages are numerous and people have been researching solid electrolytes for the past few years.

Transparent Lithium Ion Battery Invented by Stanford Researchers

Posted by Ovidiu Sandru in Energy Storage on July 27, 2011

They may not even know it, but I guess transparent batteries are the dream of every teenager or fancily-dressed girl out there. And the good news is that Yi Cui together with a team from the University of Stanford, have invented such a battery.

24M's Liquid Battery Can Be Filled With Sludgy Electrodes, Cuts Price in Half

Posted by Ovidiu Sandru in Energy Storage on May 30, 2011

24M, a spin-off from battery maker A123 has published a paper which describes a new type of battery that would outperform any existing lithium ion unit designed for electric vehicles. Today’s lithium batteries are bulky and heavy just because there’s a lot of extra material in them that doesn’t have anything with the storage of energy, but merely with supporting the active “ingredients.”

New Sodium Imide Battery Doesn't Overheat, Features 50% More Capacity

Posted by Ovidiu Sandru in Energy Storage on May 25, 2011

One of the biggest hurdles lithium ion batteries face is to overcome is heat. Today’s electric cars use complex and bulky cooling systems to get rid of the heat, fact that also lowers the batteries’ storage capacity and put weight on the car, lowering its mileage per charge. A new type of battery chemistry that doesn’t overheat is now emerging from Leyden Energy’s labs.

Company Promises to Develop Battery-Replacing Ultracapacitors in Electric Vehicles

Posted by Ovidiu Sandru in Energy Storage on May 9, 2011

For years, people have been thinking to reduce or even eliminate gasoline-powered vehicles, and switch to battery-powered ones. The the battery-powered electric vehicles’ era hasn’t already begun well enough, and now some are even thinking to replace batteries with something else: ultracapacitors.

Wheego LiFe Electric Car Out On The Market

Posted by Mihai Sandru in Electric Vehicles on April 27, 2011

It appears that the Nissan Leaf has a new contender that threatens to steal its clients away: the Wheego LiFe has recently been unveiled and sold at its dealership in Atlanta.

Xerox Researchers' Finding Can Yield 10 to 30% More Energy for Lithium Ion Batteries

Posted by Ovidiu Sandru in Energy Storage on March 4, 2011

A new printing technology invented by Xerox promises to have the ability of packing more energy into EV batteries. The invention involves the printing of a striped pattern of energy storage materials and highly conductive materials. The resulted electrodes are thicker than conventional ones, but can increase the energy stored in a battery by 10 to 30 percent.
