Which cathode material is used in thermally activated batteries?

Typical cathode material in thermally activated batteries is iron (II) sulfide (FeS 2) bearing the S 2 2 − anion. A general advantage of FeS 2 is its insolubility in molten alkali halide eutectics. Therefore it cannot diffuse to the anode and cause short circuiting [ 8 ].

How does a thermal battery work?

What is a thermally activated battery?

Summary State of the art thermally activated batteries use an alkali halide eutectic mixture that serves as electrolyte. The anode of thermal batteries is based on high melting alloys of lithium, the cathode uses either iron disulfide or cobalt disulfide which in comparison to the former allows for higher operating temperatures.

How pyrotechnic heating pellets are used to activate thermal batteries?

To activate thermal batteries pyrotechnic heating pellets are required which are integrated regularly in the stack of cells as is depicted in Fig. 1. Upon ignition the heat released causes the electrolyte to liquefy and the battery starts operating.

Who invented the thermal battery?

Thermal activation & discharge The first thermal battery was invented by German Georg Otto Erb in the 1940s and found mass use as a fuse battery in the A4 ballistic missile. This battery - based on calcium/calcium chromate – did not require a pyrotechnic heating charge but harvested the excess thermal energy provided by the rocket engine [ 19 ].

What are the hazards associated with thermal batteries?

The general hazards encountered with thermal batteries are the high container temperatures encountered upon firing and the resulting danger of fire for flammable materials adjacent to it. The hazards of bulk amounts of heat powder (84/16) have been investigated by Guidotti et al. [ 56 ].
