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 »

Spray-on Batteries

Written by , on June 29, 2012

Students at Rice University have reported in the journal Nature that they have invented a spray-on lithium-ion battery that could be applied to any surface.  Read more »

An “Infinite Range” Electric Plane

Written by , on May 11, 2012

One of the disadvantages of battery powered planes is that their weight remains the same as they fly whereas liquid fuel aircraft become lighter as they use up their fuel. This realisation led Chip Yates, holder of the world record for the fastest electric motorcycle, to the idea of dropping batteries when their charge was […]  Read more »

Electric Cars Could Refuel Like Petrol Cars

Written by , on March 12, 2012

A New York-based company, Eos Energy Storage, is developing a system that refills an electric vehicle’s battery in a way similar to the way petrol cars are refueled at service stations. Eos Energy Storage says that it can make a zinc-air battery in which the used electrolyte can be pumped out and a new electrolyte […]  Read more »

Battery Breakthrough Could Eliminate Range Anxiety

Written by , on March 7, 2012

Envia Systems, a Californian company with prototyping and production facilities in China, has developed a lithium-ion battery with roughly twice as much energy per gram as present batteries. Envia Systems found that by including manganese in a mix of materials for the cathode better energy densities could be achieved. The team then boosted the performance […]  Read more »
