New electrolyte could mean an end to spontaneously combusting lithium batteries

Last year, lithium-ion battery fires became a hot topic, pardon the inescapable pun, with both a Tesla automobile and the Boeing 787 Dreamliner succumbing to fires. In cross-disciplinary research at the University of North Carolina (UNC), a compound being studied to prevent marine life from sticking to ships may also be the solvent (and the solution) to keep lithium ion batteries from catching alight when they overheat.

Urb-E squeezes onto personal mobility train

Compact personal mobility vehicles are a great option for commuters looking to solve the "last mile" problem. The latest such vehicle to hit the streets aimed at filling this need is the Urb-E from Urban Mobility, which claims it is the "world's most compact electric vehicle."Read More

Self-healing electrode coating could lead to longer-lasting batteries

In their continuing efforts to increase the energy density of lithium-ion batteries, scientists have began looking at alternative materials for those batteries' electrodes – materials such as silicon. The problem is, electrodes swell and shrink as they absorb and release lithium ions, causing them to break down over time. This is particularly true of silicon, which is brittle by nature. Now, however, scientists have developed a conductive elastic polymer coating for those electrodes, that heals its own cracks after each use. Read More

Boeing rolls out first Dreamliner 787-9

Boeing has rolled out the first 787-9 Dreamliner variant at its Everett, Washington assembly plant. The second of three variants of the Dreamliner, the 787-9 carries more passengers and has a greater range than the 787-8 that has been in operation since 2011. The first 787-9 is scheduled to be delivered to Air New Zealand next year.Read More

Europe's "biggest battery" to regulate UK renewable energy

Europe's largest battery is to undergo testing in the UK, where it will be used to store and regulate energy generated from renewable sources such as wind and solar power, The Guardian reports. The lithium manganese battery, developed by S&C Electric Europe, Samsung SDI and Younicos, will be capable of storing up to 10 MWh of energy.Read More

Scientists create lithium-ion batteries the size of a grain of sand

While we’re currently witnessing the rise of tiny electronic devices such as biosensors, many of those devices do have one limiting factor – they still require not-so-tiny batteries, which ends up somewhat defeating the whole miniaturization process. Although some devices can get their power from external sources, scientists from Harvard University and the University of Illinois at Urbana-Champaign have come up with an alternative ... functional 3D-printed lithium-ion batteries no larger than a grain of sand.

New microbatteries combine the advantages of lithium-ion batteries and supercapacitors

There can be little doubt that people love their mobile devices. But, by leaving them high and dry at the most inconvenient of times, this love generally doesn't extend to the batteries that power said devices. New microbatteries developed by researchers at the University of Illinois at Urbana-Champaign (UIUC) that measure just a few millimeters in size, yet are powerful enough to power a mobile phone may be more likely to inspire a little love.Read More

Boeing completes final certification test of new 787 battery system

On Friday, Boeing completed the final certification test required by the United States Federal Aviation Administration (FAA) for approval of the company’s lithium-ion battery modifications for the 787 Dreamliner aircraft. The test flight was made using a Boeing-owned production airplane built for LOT Polish Airlines with the company reporting that the test was “straightforward and the flight was uneventful.” Read More
