Using an ultrasound emitter in a lithium metal battery improves charging speed and safety
Researchers in the US have included an ultrasound emitter in a lithium metal battery to improve charging speed and safety
all in one,” said Ping Liu, professor of nanoengineering at the Jacobs School. “It is exciting and effective.”

The most difficult part of the process was designing the device, said An Huang, a Ph.D. student in materials science at UC San Diego. The challenge was working at extremely small scales, understanding the physical phenomena involved and finding an effective way to integrate the device inside the battery.

“Our next step will be to integrate this technology into commercial lithium ion batteries,” said Haodong Liu, nanoengineering postdoctoral researcher at the Jacobs School.
