Sieving ions with a polymer membrane

Ion-sieving polymer membranes can perform with exquisite precision by gaining unprecedented control over pore size and uniformity within the membranes, KAUST researchers have shown.

Phonon catalysis could lead to a new field

Batteries and fuel cells often rely on a process known as ion diffusion to function. In ion diffusion, ionized atoms move through solid materials, similar to the process of water being absorbed by rice when cooked. Just like ...

Deep space mine

Many resources essential to the technology on which we depend are dwindling or are increasingly inaccessible to certain nations for geopolitical reasons. A case in point is that several of the rare metallic elements that ...

A leap in using silicon for battery anodes

The same material you'll find at the tip of a pencil—graphite—has long been a key component in today's lithium-ion batteries. As our reliance on these batteries increases, however, graphite-based electrodes are due for ...

Chasing lithium ions on the move in a fast-charging battery

A team of scientists led by the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Lawrence Berkeley National Laboratory has captured in real time how lithium ions move in lithium titanate (LTO), a fast-charging ...
