Investigation of the Causes of Thermal Run-away in Sealed Nickel-Cadmium Batteries

It is shown from analysis of charging current and voltage change on the terminals of sealed Ni-Cd battery at thermal runaway, that thermal runaway is accompanied by a new high-power electrochemical reaction, going at battery voltage of approximately 0.55 V.

Thermal runaway in nickel-cadmium batteries with sintered and extruded electrodes

It is shown by experiments that probability of thermal runway in nickel-cadmium batteries with sintered oxide-nickel electrodes is higher, than in the batteries with extruded and pasted electrodes. Besides, it is shown that the probability of thermal runaway decreases with decrease of battery capacitance.
