Ultrasound-equipped battery prevents potential fires with sound waves

It’s hard to imagine a world without the lithium-ion batteries that power today’s laptops and mobile devices, but the technology does have its limits. One way scientists are working to break a bottleneck of energy density and greatly extend the battery… Continue reading Ultrasound-equipped battery prevents potential fires with sound waves

A Safer, Self-Healing Polymer Battery

Lithium-ion batteries are notorious for spontaneously combusting, with seemingly so many ways that it can be triggered. While they are a compact and relatively affordable rechargeable battery for hobbyists, damage to the batteries can be dangerous and lead to fires.

Several engineers from the University of Illinois have developed a …read more

3D Printing Batteries

We’ve all gotten pretty adept at 3D printing keychains and enclosures. Some people can even 3D print circuit boards to an extent. But the real goal is a Star Trek-style replicator that just pushes out finished products. Printing different components would be a key technology and unless you want to …read more

New Part Day: SMD Batteries

Here’s a tip for all you retrocomputing enthusiasts or even anyone with an old computer in the garage. Go remove the battery. Yes, that old mid-90s desktop has a battery inside for the real-time clock, and it’s a ticking time bomb. Batteries leak, and they’ll spew goo all over the circuit board, irreparably damaging your piece of electronic nostalgia. This goes for all electronics, too: that badge collection is going to be a pile of broken fiberglass in a decade. Remove your batteries now.

While lithium cells soldered to a motherboard will leak, now there might be a new technology …read more

How Smart is the Grid?

Marketing and advertising groups often have a tendency to capitalize on technological trends faster than engineers and users can settle into the technology itself. Perhaps it’s no surprise that it is difficult to hold back the motivation to get a product to market and profit. Right now the most glaring example is the practice of carelessly putting WiFi in appliances and toys and putting them on the Internet of Things, but there is a similar type of fiasco playing out in the electric power industry as well. Known as the “smart grid”, an effort is underway to modernize the electric …read more
