Lithium dendrites

Latest updated: Sep 24, 2024

Dendritic metallic lithium formed when lithium ions are reduced during the charging process of a lithium-ion battery.

Note: The form of lithium when it appears on the negative electrode side is not necessarily lithium dendrites; collectively, it's referred to as lithium plating.
