Chapter 04 of 5
Dendrites and Thermal Runaway
The material failures that lead to battery fires.
- Internal Conflict
The Instability of Success
The same high reactivity that makes lithium a great energy carrier also makes it prone to dangerous structural failures.
- Microscopic Threat
What are Dendrites?
Dendrites are microscopic, needle-like lithium crystals that grow from the anode during the charging process.
- Mechanism
The Plating Problem
If lithium ions move faster than the anode can absorb them, they accumulate on the surface and solidify into spikes.
