Boeing’s Battery Blues

Despite fires in the 787’s lithium-ion batteries, planes will become more dependent on electricity and batteries

In January, regulators in Japan and the United States grounded the worldwide fleet of Boeing 787 Dreamliners after lithium-ion batteries caught fire in two of them—one in the air over Japan and the other on the ground in Boston. As IEEE Spectrum went to press, authorities were tracing the proximate cause of the Boston fire to a short-circuit in one of the batteries. The ultimate cause remained unclear. 


What is clear, though, is that lithium-ion batteries in commercial airliners are probably here to stay. Airliners are going to keep electrifying previously mechanical systems like those used for braking and de-icing, because doing so makes the aircraft much lighter and more efficient, says Cosmin Laslau, an electrochemistry expert and technology analyst for Lux Research.

When the James Webb Space Telescope (JWST) reveals its first images on 12 July, they will be the by-product of carefully crafted mirrors and scientific instruments. But all of its data-collecting prowess would be moot without the spacecraft’s communications subsystem.

The Webb’s comms aren’t flashy. Rather, the data and communication systems are designed to be incredibly, unquestionably dependable and reliable. And while some aspects of them are relatively new—it’s the first mission to use Ka-band frequencies for such high data rates so far from Earth, for example—above all else, JWST’s comms provide the foundation upon which JWST’s scientific endeavors sit.
