GE unveils Durathon battery for zero-emission buses

By - December 21, 2012 2 Pictures
General Electric’s research team has unveiled its new Durathon battery, which the company says makes it cheaper to power buses using clean energy. It is used in tandem with a lithium battery and a hydrogen fuel cell, a combination that the researchers say makes it possible for the vehicle to achieve full performance with a much smaller fuel cell than previously possible.

Machine uses artificial intelligence to sort dead batteries

By - December 19, 2012 2 Pictures
While it’s definitely important to keep the heavy metals in discarded batteries out of the environment, the sorting of all of the different types of batteries that arrive at a recycling depot could no doubt get extremely tedious. It’s the type of job that often goes to a machine. Well, such a machine has been invented. Called the Optisort, it can recognize about 2,000 types of batteries, and is currently being used to sort one third of those recycled in the UK. Read More

Plant root used to create eco-friendly lithium-ion battery

By - December 11, 2012 2 Pictures
Researchers have found an eco-friendly alternative to the metal ores currently favored in the electrodes of lithium-ion batteries. The new non-toxic and sustainable battery uses purpurin, a red/yellow dye extracted from the root of the madder plant that has been used for dying cloth for at least 3,500 years – meaning the substance can simply be grown rather than mined.

How to boost lithium battery performance – just add crushed silicon

By - November 6, 2012 2 Pictures
Researchers at Rice University and Lockheed Martin may have developed a low-cost method of creating longer-lasting, high-capacity lithium-ion batteries. Currently graphite is used as the anode in commercial li-ion products, despite the fact that a silicon anode could potentially store ten times more lithium ions. The team says it has solved one of the problems associated with silicon, which nearly triples the energy density of current li-ion batteries. Read More

New power amplifier design could double smartphone battery life

By - November 5, 2012 1 Picture
Cell phones have come a long way in terms of battery life, but lets be honest, there's still plenty of room for improvement. The very fact that we talk about using a phone for eight hours as being good is, well, bad. While next-gen battery technologies present one solution to the dilemma, a new breakthrough from MIT spinoff Eta Devices takes a different tack – by improving power amplifier efficiency the company hopes to double the battery life of smartphones.

New algorithms could allow lithium-ion batteries to charge twice as fast

By - October 5, 2012 1 Picture
The single biggest factor hindering the convenience, and therefore the adoption, of electric vehicles is the batteries used to power them. While filling up an ICE vehicle takes just a few minutes at the pump, electric vehicle recharge times are measured in hours. Engineers at the University of California, San Diego, have developed new algorithms that improve the efficiency of existing lithium-ion batteries and could allow them to be charged twice as fast than is currently possible.

The battery of the future might run on sugar

Researchers at the Tokyo University of Science have turned to sugar as part of a continuous effort to control Japan's growing import costs associated with building lithium-ion batteries. It seems that sugar may be the missing ingredient for building rechargeable batteries that are more robust, cheaper, and capable of storing more energy. Read More

Graphene paper anodes pave way for faster charging Li-ion batteries

By - August 27, 2012 1 Picture
While the lithium-ion batteries commonly used in electric cars are capable of storing a fairly large amount of energy, they’re not able to accept or discharge that energy very quickly. That’s why electric vehicles require supercapacitors, to speedily deliver energy when accelerating, or to store it when braking. Recently, however, researchers from New York’s Rensselaer Polytechnic Institute created a new anode material, that allows Li-ion batteries to charge and discharge ten times faster than those using regular graphite anodes. It could make EV supercapacitors unnecessary, and vastly shorten the charging time required by electronic devices. Read More
