After having been sent a vacuum fluorescent display (VFD) based clock for a review, [Anthony Francis-Jones] took the opportunity to explain how these types of displays work. Although VFDs are ...

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material ...

Cathodes play a dominant role in defining cell energy density, and also make up a significant proportion of cell costs, due to the use of high-cost metals such as cobalt, nickel and lithium. Standard ...

In 2020, Tesla announced a breakthrough battery that would be much cheaper to produce while offering higher energy density thanks to new technologies like dry cathode coating and silicone anode.
