тепловой разгон

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.

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.
