Engineers report progress toward lithium-metal batteries that charge fast – as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown quickly into dense layers of uniform lithium metal that lack battery-performance-degrading spikes called dendrites.

Researchers at the University of California San Diego developed an ultrasound-emitting device that brings lithium metal batteries, or LMBs, one step closer to commercial viability. Although the research team focused on LMBs, the device can be used in any battery, regardless of chemistry.

A team of researchers has developed a flexible, rechargeable silver oxide-zinc battery with a five to 10 times greater areal energy density than state of the art. The battery also is easier to manufacture; while most flexible batteries need to be manufactured in sterile conditions, under vacuum, thi

UC San Diego nanoengineers developed a safety feature that prevents lithium metal batteries from rapidly overheating and catching fire in case of an internal short circuit. The clever tweak does not prevent battery failure, but rather provides advance warning of failure and makes it much safer.

…from spent lithium ion batteries and makes them work just as good as new. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. Researchers built new batteries using the regenerated cathodes. Charge storage capacity, charging time and battery lifetime were…
