Thermal fuse high-temperature batteries

Concerns about short-circuit currents, especially internal, are very similar to those associated with Ni-Cd systems. Temperature rise to due short circuit can lead to very high temperatures at the battery case, although most cells will withstand a great deal of short-circuit abuse. These temperatures can be sufficient to cause burns or ignite flammable materials [34]. To guard against this, many modem batteries, especially those contained in a multicell pack, include integrated safety devices such as PTC resistors, thermal fuses, and thermistors to sense pack temperature remotely.
