In this study, there was first developed an analytical model of thermal runaway in alkaline batteries. The model was constructed based on the thermal runaway new mechanism experimentally deduced by us in our previous works proving that the thermal runaway was connected with initiation of a powerful exothermic reaction of atomic hydrogen recombination. It was shown that the equations obtained from the model for current and voltage changes on battery terminals during a thermal runaway correspond to experimental data with the relative error not more than 4.2%.
