| Abstract: | Three materials were tested in small‐scale baskets of cubic dimensions and analyses were performed based upon the results according to the Frank‐Kamenetskii (FK) method and the crossing point (CP) method. Comparison of the FK method and the CP method results was performed additionally. The activation energy E and the QA value were found. The relationship between critical ambient temperature and the storage size was determined as well as the relationship between CAT and time to maximum thermal runaway for the materials.
