University of Maryland presented safer Lithium batteries manufactured by ALD at AVS 64 in Tampa, Florida

Researchers demonstrate a technique to fabricate safer and more compact batteries.

WASHINGTON, D.C., October 30, 2017 -- The lithium-ion batteries that commonly power mobile phones and laptops are ubiquitous and efficient. But they can occasionally explode -- as evidenced in the batteries used by Samsung's Galaxy Note 7, which the company recalled last year.

Solid-state batteries, which eschew the flammable and unstable liquid electrolytes of conventional lithium-ion batteries, could be a safer option. Now, researchers have demonstrated a new way to produce more efficient solid-state batteries. This proof-of-principle study may lead to safer and more compact batteries useful for everything from sensor networks to implantable biomedical devices.

Alex Pearse, a doctoral student at the University of Maryland, College Park and the Nanostructures for Electrical Energy Storage, a DOE-sponsored Energy Frontier Research Center, will present this work during the AVS 64th International Symposium and Exhibition being held Oct. 29-Nov. 3, 2017, in Tampa, Florida.
