Power Supplies & Batteries

A team of researchers from Stanford University and the Department of Energy’s (DOE) SLAC National Accelerator Laboratory have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries.

It could happen someday, say a group of mechanical engineering students at Rice University, Houston, TX. As a project required for graduation, four seniors created PediPower shoes that extract and store energy with every step to power portable electronics and, maybe even medical devices.

Scientists at Carnegie Mellon University, Pittsburgh, PA, are developing edible electronic devices that can be implanted in the body, and say that the device could be programmed and deployed in the gastrointestinal tract or the small intestine and once the battery packaging is in place,...

The demand for ever-smaller electronic devices has led to the miniaturization of a variety of technologies, but energy-storage units, such as batteries and capacitors, have lagged behind. Now, researchers at UCLA say that they have developed an innovative technique using a DVD burner to...

Researchers at Northwestern University, Evanston, IL and the University of Illinois have demonstrated a stretchable lithium-ion battery can power their innovative stretchable electronics. The stretchable electronic devices now could be used anywhere, including inside the human body, they say,...
