Modeling Internal Shorting Process in Large-Format Li-Ion Cells

The temperature behavior is significantly different from that of the large resistance case. The temperatures in both SCO and Al tab jump to above 500°C immediately following the short-circuit. Therefore, in contrast to the large resistance case, two hot spots are formed, one on the tabs and the other on the SCO.

Electrical Principles

The internal resistance of a chemical battery is typically between a fraction of an ohm and a few ohms, and is mainly due to the resistance of the electrolytic materials used in the manufacture of the battery. Current …
