(Phys.org) —Single-walled carbon nanotubes (SWCNTs) are being widely studied for their potential applications in many areas; for example, as electrode materials for energy storage, as transparent conductive films, and as ...
How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current ...

(Phys.org)—Scientists with a common goal, to figure out an alternative to the lithium ion battery, the main power source of choice, are not giving up. The quarrel is not with the lithium ion battery's performance but in ...
(PhysOrg.com) -- New high resolution images of electrode wires made from materials used in rechargeable lithium ion batteries shows them contorting as they become charged with electricity. The thin, nano-sized wires writhe ...

(PhysOrg.com) -- Working together, Matthieu Gaudet and Steve Arscott from the University of Lille (IEMN lab) in France have built a circuit using a phenomenon known as photoelectrowetting, which allows a switch to be turned ...
Rechargeable batteries based on magnesium, rather than lithium, have the potential to extend electric vehicle range by packing more energy into smaller batteries. But unforeseen chemical roadblocks have slowed scientific ...
