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.

Using computer simulations and X-ray experiments, researchers could “see” in detail why lithium ions move slowly in a solid-state battery—specifically, at the electrolyte-electrode interface. The work could lead to new strategies to enhance ionic conductivity in solid-state batteries.

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…
