The National Transportation Safety Board has released its findings regarding the investigation it conducted following the events that led to the grounding of 50 long-range Boeing 787s. According to its report, a series of failures have been attributed to the Federal Aviation Administration (FAA), Boeing Co., and its supplier of lithium-ion batteries. Back in January 2013, ground workers at Boston Logan International Airport noticed that smoke and flames were coming from an auxiliary power unit lithium-ion battery that was in a Japan Airlines 787 Dreamliner that was parked at a gate. A second incident... Read more...
It seems we're constantly hearing about breakthroughs in battery technology, and though some of today's laptops and tablets boast all-day battery life, we're still waiting for the killer technology that will enable days, if not weeks and months of run time. A new lithium-ion battery developed by German scientists won't get us any closer to that goal, but it could be a big deal for electric vehicles. Using materials that exclusively originate from German companies, scientists at Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (ZSW, from here on out) created a Li-ion...

Researchers are still searching for the Holy Grail in battery technology that will ultimately hold a charge for much longer than what's currently available and be affordable to the masses. One that has promise is a new all-solid lithium-sulfur battery developed by scientists at the Department of Energy's Oak Ridge National Laboratory (ORNL). The research team, led by Chengdu Liang, claims the lithium-sulfur battery has around four times the energy density of conventional lithium-ion technologies found in today's devices, and it's pretty cheap to boot. "Our approach is a complete change from the... Read more...
Over the past few years, we've seen a number of recalls involving faulty batteries that can overheat and cause a fire. Now there's a new technology called Stoba that could be on the market as soon as the first quarter of next year that could help prevent lithium-ion batteries from catching fire or exploding in devices such as laptops and mobile phones. Stoba was developed at the Industrial Technology Research Institute (ITRI), Taiwan's national research organization. When lithium-ion batteries develop internal shorts, it doesn't take long before they can heat up to as much as 932 degrees Fahrenheit,... Read more...
