New Flow Battery Promises Lower Cost Grid Storage

Written by , on May 9, 2013

Researchers from the U.S. National Accelerator Laboratory and Stanford University have develpoed a new type of flow battery which could potentially provide low-cost, long-life storage for solar and wind energy. Current flow batteries pump two different liquids through an interaction chamber where dissolved molecules undergo chemical reactions that store or release energy. The chamber contains […]  Read more »

Microbatteries Offer Both Power and Energy

Written by , on April 18, 2013

Researchers at the University of Illinois at Urbana-Champaign have developed new microbatteries which out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics. Currently capacitors are used for applications that need a lot of power because they can release energy very quickly – however, can only store a small […]  Read more »

Redox Flow Battery Capacity Increased 8-fold

Written by , on March 19, 2013

Scientists at Germany's Fraunhofer Institute have announced an important breakthrough in the development of a redox flow battery that reaches stack power up to 25 kilowatts. This is eight times larger than previous systems. Redox flow batteries store electrical energy in chemical liquid electrolytes. The electrolytes are charged and discharged in small reaction chambers. Several […]  Read more »

PV Charger Built into Phone Screen

Written by , on March 5, 2013

Wysips, a company based in Aix-en-Provence, in southern France, has developed a photovoltaic film which can be built into a mobile phone, laptop or tablet screen and charge the battery from any artificial or natural light source. According to Wysips chief executive, Ludovic Deblois, “With 10 minutes in the sun you will be able to […]  Read more »

Silicon Anode Gives Lithium-ion Battery Superior Performance

Written by , on February 14, 2013

Researchers at the University of Southern California have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes. The new batteries hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. Silicon, which is cheap and has a high potential capacity, would […]  Read more »

Flexible Lithium-ion Batteries

Written by , on January 17, 2013

Researchers at South Korea's Ulsan National Institute of Science and Technology have developed a lithium-ion battery so flexible that it can be tied in a knot. Traditional batteries use liquefied electrolytes in hard cases. These hard casings prevent flexibility and create a risk of explosion should heat melt the film that separates electrolytes. In a […]  Read more »

Sodium Battery Progress – Less than Reported

Written by , on November 24, 2012

Currently, the leading battery technology is lithium-ion. These batteries work well and can be recharged hundreds of times. The problem is that lithium is not cheap and is likely to become more expensive as demand for batteries increases. After lithium, the next most attractive element is sodium. Sodium is extremely plentiful and cheap. The problem […]  Read more »

Crushed Silicon Boosts Battery Performance

Written by , on November 15, 2012

Researchers at Rice University have developed a low-cost method of creating longer-lasting, high-capacity lithium-ion batteries using crushed silicon film, rather than cgraphite, as the anode. Currently, graphite is used as the anode in lithium-ion batteries, despite the fact that a silicon anode could potentially store ten times more lithium ions. The problem with silicon is […]  Read more »

Sodium-ion Battery for Affordable Grid-scale Storage

Written by , on August 13, 2012

Researchers at  Murdoch University in Perth, Western Australia, have developed a water-based sodium-ion battery which they say shows excellent potential for affordable, grid-scale energy storage. Other storage technologies, such as molten salt or molten sulfur, work at high temperatures, making them expensive to use. The water-based sodium-ion battery provides more affordable low-temperature storage. The battery […]  Read more »

New Coolant Could Double Battery Life

Written by , on July 18, 2012

Researchers at the Fraunhofer Institute in Oberhausen, Germany, have developed a new fluid for cooling the expensive batteries in electric cars and, thereby, extending their life. The fluid, called "CryoSolplus" is a mixture of water, paraffin, anti-freeze and a stabilization agent. It can absorb three times as much heat as water and, therefore, needs a […]  Read more »
