Researchers Prevent Fires in Next-Gen Lithium Batteries

New research from SLAC National Accelerator Laboratory, Menlo Park, CA, could help remove a major barrier to developing lithium-sulfur and lithium-air batteries. The SLAC engineering team discovered that adding two chemicals to a lithium metal battery's electrolyte prevents the formation of dendrites, “fingers” of lithium that pierce the barrier between the battery’s halves and cause electrical shorts, overheating, and fires. The engineers discovered that adding both chemicals, in specific amounts, stopped lithium dendrite formation and the lithium metal electrode acquired a stable protective coating that improved the battery’s performance.

The Truth about Parylene Coating & Medical Devices

Parylene is the generic name for members of a unique polymer series. Parylene conformal coatings represent a distinct family of organic polymeric coating materials that are polycrystalline and linear in nature, with innumerable commercial applications. Resilient, dielectric, and pinhole-free, parylenes are frequently selected for use with products subjected to ongoing conditions of duress that might otherwise diminish their performance.

Coming Soon - Design for Manufacturability - Advanced technologies that aid engineers in the transition from design to production

In conjunction with SAE The aerospace industry is embracing technological breakthroughs concerning advanced materials and additive manufacturing to maximize manufacturing efficiencies. As a result, engineering’s emphasis has switched from understanding the basics of advanced materials and additive manufacturing to incorporating them into the early stages of designs. This webcast will look at processes and tools being used by engineers throughout the industry to maximize the communication and collaboration skills between design and manufacturing so that better decisions are made early in the development stage, no matter how small the component or how big the aircraft. Webinar attendees will be invited to interact with the experts during an Audience Q&A.

Will remote-controlled passenger flights take off in the next 5 years?

This week's Question: Last month, the Manassas, VA-based Aurora Flight Sciences Corp. tested its 4100-pound twin-propeller experimental airplane. The Centaur flew without a pilot and within airspace also being used by commercial aircraft. John Langford, the CEO of Aurora, is very optimistic about the test flight and the future of Centaur and other unmanned aircraft. Langford recently told CNN: “I’m a huge believer that the unmanned airplane revolution will make aviation safer for everybody. That isn’t to say there won’t be accidents, but the overall level of safety will go up as the robotic stuff is introduced.” Merging large unmanned aircraft into commercial airspace will require adjustments to aircraft and operator certification, air traffic control, and the FAA's air traffic system. Langford believes that planes like Centaur will be able to fly with FAA approval in 5 to 7 years. What do you think? Will remote-controlled passenger flights take off in the next 5 years?
