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 »

Cheap Plastic Absorbs CO2 from the Air

Written by , on February 20, 2012

Scientists at the Loker Hydrocarbon Research Institute and the University of Southern California, Los Angeles have produced a cheap plastic capable of removing large amounts of carbon dioxide from the air. The material has the potential to be used in large-scale batteries as well as "artificial trees" to remove carbon dioxide from the air. The […]  Read more »

Solid State Batteries – More Power and No Fire Risk

Written by , on January 11, 2012

Solid-state batteries store energy in thin, solid film, rather than in a liquid like conventional lithium ion batteries. They are much lighter than standard batteries and, unlike standard lithium ion gatteries, they are not prone to catch fire when they are stressed. One company working on developing solid state lithium ion batteries is Sakti3 Inc, […]  Read more »
