New research from Sandia National Laboratory is moving toward advancing solid state lithium-ion battery performance in small electronics by identifying major obstacles in how lithium ions flow across battery interfaces.
The team of researchers, including ECS member Forrest Gittleson, looked at the nanoscale chemistry of solid state batteries, focusing on the area where the electrodes and electrolytes make contact.
“The underlying goal of the work is to make solid-state batteries more efficient and to improve the interfaces between different materials,” says Farid El Gabaly, coauthor of the recently published work. “In this project, all of the materials are solid; we don’t have a liquid-solid interface like in traditional lithium-ion batteries.”
According to El Gabaly, the faster the lithium can travel from one electrode to the other, the more efficient the batteries could be.
