Abstract
It is well understood that lithium metal
should not
exist in lithium
ion
batteries, but high energy/high rate lithium ion cells did not seem to have gotten this memorandum. Dissection of commercial cells often indicates direct and indirect evidence of metallic lithium present in the battery. This lithium is often called "dead" lithium as it is considered no longer active. In this presentation we motivate the nomenclature
zombie
lithium because it is, in this construction, truly undead. Lithium metal that is present in lithium ion batteries is never completely isolated from the other activities of the cell, and as the cell ages, without proper understanding, the "dead" lithium can suddenly arise and impact the cell is decidedly negative ways.
In this presentation we will review and (try to) understand behavior of zombie lithium generated during the operation of a lithium ion battery and time scale and length scales of its impact across the cell and the system.
