Battery knowledge · Aging and degradation
Dendrite
A tree-like metal deposit that can grow from the negative electrode through the separator, raising self-discharge or causing an internal short circuit. [1]
Example
Aging and degradation: an example situation
Capacity loss and resistance rise can have different causes; a film-growth curve cannot identify both.
Read Dendrite alongside Internal short circuit in this context. An unintended electronic path between the electrodes inside a cell — through a metal particle, a burr, a damaged separator or lithium deposits. It discharges the cell internally and turns its energy into local heat.
