Blocking lithium dendrite growth in solid-state batteries with an ultrathin amorphous Li-La-Zr-O solid electrolyte

Abstract

The formation and growth of dendrites in solid-state lithium metal batteries is a common cause of failure. Here, thin-film amorphous Li-La-Zr-O shows high resistance to lithium penetration, making it promising for thin-film solid-state batteries and as a coating for bulk ceramic electrolyte.
