A new discovery could finally usher the development of solid-state lithium batteries, which would be more lightweight, compact, and safe than current lithium batteries. The growth of metallic filaments called dendrites within the solid electrolyte has been a longstanding obstacle, but the new study explains how dendrites form and how to divert them.

International team of researchers describe new fossil species discovered in fossil deposit near Llandrindod Wells in mid-Wales. The fossil, Mierridduryn bonniae, shares many features with Cambrian 'weird wonder' Opabinia, but is 40 million years younger. Robust phylogenetic analyses suggest that Mierridduryn is either the third opabiniid ever discovered, or is a distinct group that is key for understanding the evolution of the arthropod head.

Lithium-ion (Li-ion) batteries are used to power everything from smart watches to electric vehicles, thanks to the large amounts of energy they can store in small spaces. When overheated, however, they're prone to catching fire or even exploding. But recent research offers a possible solution with a new technology that can swiftly put the brakes on a Li-ion battery, shutting it down when it gets too hot.

Pumping up thermal water, separating lithium, and using it to produce batteries for electric mobility -- the idea of lithium as an environmentally compatible and regionally available by-product of geothermal energy plants appears highly promising. However, it has not been clear so far whether domestic lithium extraction is really worthwhile. A team of researchers has now summarized the state of the art, analyzed raw materials markets, and assessed technologies.
