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.

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.

Power to the Batteries New center promises better batteries for low-carbon future Better solar panels and wind turbines are important to helping ensure a low-carbon future. But they are not enough. The energy from these intermittent sources must be stored, managed, converted and accessed when it’s needed most. And the…

…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…

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

…to the challenge. Rechargeable batteries are ubiquitous in every aspect of modern life. They power our cell phones, laptops, and portable electronics. In the very near future, they will also power our environmentally friendly electric cars. In light of these increasingly demanding applications, researchers have been trying to develop batteries…
