Lithium-ion

Yu Wang and Katie Zhong, with their gum-inspired electrolyte

Although high-capacity lithium batteries make many of today's mobile electronics possible, they do have one flaw – they occasionally catch fire. This can happen when they overheat, and their liquid acid electrolyte ignites and leaks out. Now, however, scientists at Washington State University have created a gummy electrolyte material that could make such fires a thing of the past.  Read More

The Urb-E electric riding implement folds into a remarkably compact package (Photo: Urb-E)

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

A prototype lithium-ion battery, that incorporates the polymer

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

The 787-9 is the second Dreamliner variant (Photo: Boeing)

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 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

One of the lithium-ion 'microbatteries'

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.  Read More

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

The Boosted Boards skateboard

Last year we reported on San Francisco-based startup Boosted Boards' eponymous debut product, an electric skateboard that can lay credible claim to being the world’s lightest electric vehicle. The skateboard was the subject of a successful Kickstarter campaign, and having survived the perils of moving from pitch to product, is now available for wider pre-order.  Read More

The 787 Dreamliner used in the test

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

The Boeing 787 Dreamliner on display in Paris

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.  Read More
