    A train car carrying lithium batteries exploded just north of downtown Houston on Sunday. The blast was so strong, it broke windows in nearby homes. "The moment that I got into the threshold and got inside an explosion went off and it threw me into the other side of the door, so there was a tremendous amount of force – I had no idea what was happening." said Tashi Garcia, who lives nearby the railroad tracks. After the ringing in his ears subsided, he said he checked out the damage to his home. There were broken windows and cracks along...

    Anyone who has a portable device — including smartphones, tablets, laptops, smartwatches and fitness trackers — is obviously familiar with a lithium-ion (Li-ion) battery because most (if not all) of these devices are powered by this kind of battery. We’ve been okay with the rechargeable for a while, but as lithium-ion batteries are now close to reaching their maximum storage capacity (in other words, battery life can’t be extended any more), and with the horror stories about phone batteries that explode or burn, the search is on for an alternative battery that can meet our demands better and safer. So...

    Greens and technically challenged scribes apparently believe that battery-powered cars and planes are exciting new clean “zero-emissions” vehicles. There is little new about batteries – battery-powered cars were running on British roads over a century ago. They were pushed out of the market by internal combustion engines. Batteries just store energy made elsewhere, and all have a finite life. Every battery needs primary energy and resources for production, recharging, replacing, and recycling, and every step produces its own emissions. Batteries require lots of expensive raw materials – lead, calcium, nickel, cadmium, lithium, hydrogen, plus ancillary copper, steel, zinc, aluminium, and...

    Well it seems the battery gods have heard our call and bestowed upon us a miracle.Researchers at the University of California Irvine (UCI) may have discovered a way to drastically increase the life of modern day batteries. And the best part is that they stumbled upon this solution by accident.To be more specific, the discovery was made by fifth-year PhD student, Mya Le Thai. Mya was working on an electrolyte gel that was to substitute the electrolyte liquid currently found in batteries in an attempt to make it more affordable. But in a coincidental twist of fate (thank you...

    MnO2-coated batteries can now last 400 years, 200,000 cycles Doctoral research student Maya Le Thai was working in her laboratory with nanobatteries one day when she decided to try a new approach. She coated an entire gold nanowire with a manganese dioxide MnO2 shell and covered the assembly with a "plexiglass-like" electrolyte gel, but the resulting outcome was completely unexpected. As she "playfully" experimented with different materials, the resulting nanobattery produced effectively "unlimited" lifetime charge cycles lasting well over 400 years. Traditional nanowire-based batteries are thousands of times thinner than a human hair, highly conductive and feature a large...

    Jeffrey Grossman thinks we've been looking at coal all wrong. Instead of just setting it afire, thus ignoring the molecular complexity of this highly varied material, he says, we should be harnessing the real value of that diversity and complex chemistry. Coal could become the basis for solar panels, batteries, or electronic devices, he and his research team say. Read more at: http://phys.org/news/2016-04-electronics-coal.html#jCp

    Consumer technology company Sony is recalling battery packs for certain models of its Vaio laptop over concerns faults with the kit could cause the device to catch fire. It's the third major recall of battery packs from a laptop manufacturer in just a month. In February, both Toshiba and Panasonic recalled battery packs sold with their laptops and notebooks over similar fire hazard concerns. The month prior, Apple was forced to recall wall power chargers due to their potential to cause electric shock, while Microsoft asked 285,000 Australian customers to send back power cords for its Surface Pro devices over...

    The blimp that broke loose from an Army facility in Maryland last fall, wreaking havoc with its milelong tether, flew uncontrolled for hours because someone neglected to put batteries in its automatic-deflation device, Pentagon investigators have found. The pilotless, radar-carrying blimp was part of the troubled JLENS missile-defense system, which has failed to perform as promised while costing taxpayers more than $2.7 billion since 1998. The runaway blimp episode was caused by a cascade of events spanning 13 hours, according to people familiar with the investigation, an overview provided to congressional staff members and a summary released by a military...

  • Hemp nanosheets could be better than graphene for making the ideal supercapacitor

    06/17/2015 2:21:57 AM PDT · by 2ndDivisionVet · 21 replies
    As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors, according to David Mitlin, Ph.D. Supercapacitors are energy storage devices that have huge potential to transform the way future electronics are powered. Unlike today’s rechargeable batteries, which sip up energy over several hours, supercapacitors can charge and discharge within seconds. But they normally can’t store nearly as much energy as batteries, an important property known as energy density. One approach researchers...
