Elon Musk: I can fix Boeing's battery problem

By - March 11, 2013 4 Pictures
Elon Musk says he's still waiting for a call from Boeing to fix the jumbo jet maker's overheating Dreamliner battery problem. For the past few months, Boeing's 787 fleet has been grounded in the United States following a lithium-ion battery that caught fire in flight. The National Transportation Safety Board was unable to determine the cause of the fire, but the Tesla and SpaceX CEO says the problem is clear to him, and he's willing to "do the fix" for Boeing.

Experimental lithium-ion battery can be stretched, twisted and wirelessly charged

By - February 27, 2013 3 Pictures
Thanks to the advent of stretchable electronics, we’re currently witnessing the development of things like smart fabrics, bendable displays, and even pressure-sensitive skin for robots. In many potential applications, however, the usefulness of such electronics would be limited if they still had to be hooked up to a rigid battery. In response to that problem, a team of scientists have recently created – you guessed it – a stretchable lithium-ion battery. Read More

Silicon nanoparticles used to create a super-performing battery

By - February 14, 2013 1 Picture
In some peoples’ opinion, electric cars won’t become truly viable until their batteries offer a lot more driving range, and can be recharged much more quickly than is currently possible. Well, those people may soon be getting their wish. Scientists at the University of Southern California have developed a new type of lithium-ion battery, that they claim holds three times as much energy as a conventional li-ion, and can be recharged in just ten minutes.

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.
