Lithium's Narrow Paths Limit Batteries

If you could shrink enough for a fantastic voyage across a lithium battery electrode, you'd see the level of charge at every scale is highly uneven. This is not good for the battery's health. Researchers who recognize the problem worked to view in great detail how the various particles in an electrode interact with lithium during use.

Tracking Pileups on Battery Charging Route to Drive Performance

Because of their high storage capacity, metal oxides are a promising class of potential conversion-type electrode materials for next-generation lithium-ion batteries. Conversion-type electrode materials undergo conversion reactions; when they react with lithium ions, they get converted into entirely new products. Today's commercial batteries are based on a completely different mechanism called intercalation.

'Founding Father' of Lithium Ion Batteries Helps Solve 40 Year Problem

In the late 1970s, M. Stanley Whittingham was the first to describe the concept of rechargeable lithium-ion batteries, an achievement for which he would share the 2019 Nobel Prize in Chemistry. Yet even he couldn't have anticipated the complex materials science challenges that would arise as these batteries came to power the world's portable electronics.

New Possibilities for 3D-Printing Human Tissue, Vocal Chord Repair

There is no replacement for the vocal cords when damage is severe or permanent. Now, a team of materials scientists has developed a soft material with promise of new treatments in the future. Their novel soft material, called an elastomer, is very stretchable and 10,000 times softer than a conventional rubber, matching the mechanical properties of vocal cords. The elastomer can be 3D printed for use in health care.

Forget about it: A material that mimics the brain

Inspired by human forgetfulness - how our brains discard unnecessary data to make room for new information - scientists conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually 'forgets.' This could one day be used for advanced bio-inspired computing.
