Observation of Lithium Dendrites at Ambient Temperature and Below

C short-circuit most rapidly due in part to a favorable morphology at this temperature. The experimentalapproach has broad applicability to other electrochemical energy storage technologies where mass transport limitations are presentat low temperatures, particularly Li-air, Li-S, and Zn-air batteries.© The Author(s) 2014.
