Lithium-ion batteries, used in consumer devices and electric vehicles, typically last hours or days between charges. However, with repeated use, they degrade and need to be charged more frequently. Now, researchers are considering radiocarbon as a source for safe, small and affordable nuclear batteries that could last decades or longer without charging.

Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method.

A new strategy for recycling spent lithium-ion batteries is based on a hydrometallurgical process in neutral solution. This allows for the extraction of lithium and other valuable metals in an environmentally friendly, highly efficient, and inexpensive way. The leaching efficiency is improved by a solid-solid reduction mechanism, known as the battery effect, as well as the addition of the amino acid glycine.
